The SVM already verifies this for the onchain +space. Both address spaces are checked before creation, preventing re-init +attacks, even if the account is currently cold. + + Miners automatically compress when +virtual rent is below threshold (e.g., multiple epochs without any writes). In +practice, cold markets should be rare. The common path (hot) has no extra +overhead and does not increase CU or txn size. + + +No. Any write bumps the virtual rent balance. Active accounts do not get compressed. + + + No. Helius and Triton run +the Interface RPC endpoints, self-hosting the Photon indexer is optional. Helius +Labs maintains the open-source Photon indexer implementation. + + +Hot markets work all the same as long as Solana is up. Cold accounts cannot be loaded into hot state until your indexer or RPC provider recovers. +Note that compression is cryptographically verifiable, so integrity and safety are not dependent on the indexer or any other external service beyond the onchain protocol. + + + +When accounts compress after extended inactivity, the on-chain rent-exemption is released back +to the rent sponsor. This creates a revolving fund: active "hot" accounts hold a +rent exempt balance temporarily, inactive "cold" accounts release it back. The +rent sponsor must be derived from the program owner. For all mint, ATA, and +token accounts, the Light Token Program is the rent sponsor. For your +program-owned PDAs, the SDK derives a rent sponsor address automatically. + + +--- + + +API is in Beta and subject to change. + +Questions or need hands-on support?

+description: Query Light Protocol and related repositories via DeepWiki MCP. Use when answering questions about compressed accounts, Light SDK, Solana development, Claude Code features, or agent skills. Triggers on technical questions requiring repository context.
+---
+
+# DeepWiki Research
+
+Query repositories via DeepWiki MCP to answer technical questions with precise, source-backed answers.
+
+## Execution Steps
+
+### 1. Initialize Context: Understand Current Repository
+
+### 2. Identify Question Scope
+
+Determine the domain:
+- Programs, client SDKs, architecture, implementation details
+- Specific components (LightAccount, ValidityProof, CPI, etc.)
+
+### 3. Fetch Repository Context
+
+Select the appropriate repository based on question scope:
+
+**Light Protocol (compressed accounts, state trees, ZK compression, Light SDK)**
+```
+mcp__deepwiki__read_wiki_structure("Lightprotocol/light-protocol")
+mcp__deepwiki__read_wiki_contents("Lightprotocol/light-protocol")
+mcp__deepwiki__ask_question("Lightprotocol/light-protocol", "your question")
+```
+
+**Solana Development (programs, accounts, general Solana)**
+```
+mcp__deepwiki__read_wiki_structure("blueshift-gg/blueshift-dashboard")
+mcp__deepwiki__read_wiki_contents("blueshift-gg/blueshift-dashboard")
+mcp__deepwiki__ask_question("blueshift-gg/blueshift-dashboard", "your question")
+```
+
+**Claude Code (CLI features, commands, configuration)**
+```
+mcp__deepwiki__read_wiki_structure("anthropics/claude-code")
+mcp__deepwiki__read_wiki_contents("anthropics/claude-code")
+mcp__deepwiki__ask_question("anthropics/claude-code", "your question")
+```
+
+**Agent Skills (skills, subagents, patterns)**
+```
+mcp__deepwiki__read_wiki_structure("anthropics/skills")
+mcp__deepwiki__read_wiki_contents("anthropics/skills")
+mcp__deepwiki__ask_question("anthropics/skills", "your question")
+```
+
+### 4. Apply Precision Rules
+
+**AVOID:**
+- Vague verbs: "handles", "manages", "processes", "enables", "provides"
+- Abstract nouns: "operations", "management", "coordination"
+- -ing endings when a precise verb exists
+- Marketing language: "comprehensive", "rich", "seamless"
+
+**USE:**
+- Exact function/method names
+- Concrete data structures
+- Specific operations: "sets discriminator", "creates hash", "nullifies account"
+- File:line references
+
+### 5. Format Response
+
+Structure answers with:
+- Technical precision
+- Code examples with inline comments
+- Source references (file paths, line numbers)
+
+## Example Output
+
+**Question:** What do you include in instruction data for compressed account creation?
+
+**Answer:**
+
+---
+
+## Compressed Account Creation Instruction Data
+
+Instruction data contains three components for proof verification and tree coordination.
+
+**Components:**
+
+```rust
+pub struct InstructionData {
+    proof: ValidityProof,
+    address_tree_info: PackedAddressTreeInfo,
+    output_state_tree_index: u8,
+    // + custom account data
+}
+```
+
+**1. Non-inclusion proof**
+- `ValidityProof` proves the derived address does not exist in the specified address tree
+- Client generates via `getValidityProof()` RPC call
+
+**2. Tree location parameters**
+- `PackedAddressTreeInfo`: Specifies which address tree registers the address (u8 index, not pubkey)
+- `output_state_tree_index`: Specifies which state tree stores the compressed account hash
+
+**3. Custom account data**
+- Program-specific fields (e.g., `message: String`, user data)
+
+**Execution flow:**
+
+1. Address tree proves uniqueness, stores address
+2. State tree stores account hash
+3. ValidityProof cryptographically guarantees address is unused
+
+**Why separate trees:**
+
+Compressed accounts require client-generated cryptographic proof that address doesn't exist (unlike regular Solana where runtime checks PDA existence). Address trees enforce uniqueness; state trees store account hashes.
+
+**Packed structs** use `u8` indices to reference accounts in `remaining_accounts`, reducing transaction size.

+# Airdrop
+
+Distribute compressed tokens to multiple recipients using TypeScript client.
+
+## Quick Decision
+
+| Scale | Approach |
+|-------|----------|
+| <10,000 recipients | Single transaction - see [Simple Airdrop](#simple-airdrop-10000-recipients) |
+| 10,000+ recipients | Batched with retry - see [Batched Airdrop](#batched-airdrop-10000-recipients) |
+| No-code | [Airship by Helius](https://airship.helius.dev/) (up to 200k) |
+
+## Core Pattern
+
+```typescript
+import { CompressedTokenProgram, getTokenPoolInfos, selectTokenPoolInfo } from "@lightprotocol/compressed-token";
+import { bn, createRpc, selectStateTreeInfo, buildAndSignTx, sendAndConfirmTx } from "@lightprotocol/stateless.js";
+import { ComputeBudgetProgram } from "@solana/web3.js";
+
+const rpc = createRpc(RPC_ENDPOINT);
+
+// 1. Get infrastructure
+const treeInfo = selectStateTreeInfo(await rpc.getStateTreeInfos());
+const tokenPoolInfo = selectTokenPoolInfo(await getTokenPoolInfos(rpc, mint));
+
+// 2. Build compress instruction (SPL -> compressed to multiple recipients)
+const ix = await CompressedTokenProgram.compress({
+  payer: payer.publicKey,
+  owner: payer.publicKey,
+  source: sourceAta.address,           // SPL ATA holding tokens
+  toAddress: recipients,                // PublicKey[]
+  amount: recipients.map(() => bn(amount)),
+  mint,
+  tokenPoolInfo,
+  outputStateTreeInfo: treeInfo,
+});
+
+// 3. Send with compute budget (120k CU per recipient)
+const instructions = [
+  ComputeBudgetProgram.setComputeUnitLimit({ units: 120_000 * recipients.length }),
+  ix,
+];
+const { blockhash } = await rpc.getLatestBlockhash();
+const tx = buildAndSignTx(instructions, payer, blockhash, []);
+await sendAndConfirmTx(rpc, tx);
+```
+
+## Setup: Create Mint
+
+```typescript
+import { createMint } from "@lightprotocol/compressed-token";
+import { getOrCreateAssociatedTokenAccount, mintTo } from "@solana/spl-token";
+
+const { mint } = await createMint(rpc, payer, payer.publicKey, 9);
+const ata = await getOrCreateAssociatedTokenAccount(rpc, payer, mint, payer.publicKey);
+await mintTo(rpc, payer, mint, ata.address, payer.publicKey, 100_000_000_000);
+```
+
+## Compute Units
+
+| Recipients/instruction | CU |
+|----------------------|-----|
+| 1 | 120,000 |
+| 5 | 170,000 |
+| Batched tx | 500,000 |
+
+## Lookup Tables
+
+Reduce transaction size:
+
+| Network | Address |
+|---------|---------|
+| Mainnet | `9NYFyEqPkyXUhkerbGHXUXkvb4qpzeEdHuGpgbgpH1NJ` |
+| Devnet | `qAJZMgnQJ8G6vA3WRcjD9Jan1wtKkaCFWLWskxJrR5V` |
+
+## Simple Airdrop (<10,000 recipients)
+
+Single transaction approach for small distributions.
+
+```typescript

+    toAddress: recipients,
+    amount: amounts,

+
+// Use lookup table to reduce tx size

+
+### Verify Distribution
+
+```typescript
+for (const recipient of recipients) {
+  const accounts = await rpc.getCompressedTokenAccountsByOwner(recipient, { mint });
+  const balance = accounts.items.reduce((sum, acc) => sum + Number(acc.parsed.amount), 0);

+# Compressed PDAs
+
+The base library to use Compressed Accounts in Solana on-chain Rust and Anchor programs.
+Compressed accounts do not require rent-exemption, which makes them suitable for:
+- user owned accounts
+- not config accounts which are often read
+- not pool accounts, since compressed accounts cannot be used concurrently
+
+Compressed Accounts store state as account hashes in State Merkle trees.
+and unique addresses in Address Merkle trees.
+Validity proofs (zero-knowledge proofs) verify that compressed account
+state exists and new addresses do not exist yet.
+
+- No rent exemption payment required.
+- Constant 128-byte validity proof per transaction for one or multiple compressed accounts and addresses.
+- Compressed account data is sent as instruction data when accessed.
+- State and address trees are managed by the protocol.
+
+For full program examples, see the [Program Examples](https://github.com/Lightprotocol/program-examples).
+For detailed documentation, visit [zkcompression.com](https://www.zkcompression.com/).
+For pinocchio solana program development see [`light-sdk-pinocchio`](https://docs.rs/light-sdk-pinocchio).
+For rust client development see [`light-client`](https://docs.rs/light-client).
+For rust program testing see [`light-program-test`](https://docs.rs/light-program-test).
+For local test validator with light system programs see [Light CLI](https://www.npmjs.com/package/@lightprotocol/zk-compression-cli).
+
+### Difference to Light-Accounts (Light-PDA)
+Light-PDA's are Solana accounts with sponsored rent-exemption.
+There is no proof required for interactions with Light-PDA's which makes
+them suitable for Defi Usecases. Compressed PDA's don't require rent-exemption,
+but a proof for interactions.
+
+## Using Compressed Accounts in Solana Programs
+
+1. [`Instruction`](https://docs.rs/light-sdk/latest/light_sdk/instruction/)
+    - `CompressedAccountMeta` - Compressed account metadata structs for instruction data.
+    - `PackedAccounts` - Abstraction to prepare accounts offchain for instructions with compressed accounts.
+    - `ValidityProof` - Proves that new addresses don't exist yet, and compressed account state exists.
+2. Compressed Account in Program
+    - [`LightAccount`](https://docs.rs/light-sdk/latest/light_sdk/account/) - Compressed account abstraction similar to anchor Account.
+    - [`derive_address`](https://docs.rs/light-sdk/latest/light_sdk/address/) - Create a compressed account address.
+    - `LightDiscriminator` - DeriveMacro to derive a compressed account discriminator.
+3. [`Cpi`](https://docs.rs/light-sdk/latest/light_sdk/cpi/)
+    - `CpiAccounts` - Prepare accounts to cpi the light system program.
+    - `LightSystemProgramCpi` - Prepare instruction data to cpi the light system program.
+    - [`InvokeLightSystemProgram::invoke`](https://docs.rs/light-sdk/latest/light_sdk/cpi/) - Invoke the light system program via cpi.
+
+## Client Program Interaction Flow
+
+```text
+ ├─ Client
+ │  ├─ Get ValidityProof from RPC.
+ │  ├─ pack accounts with PackedAccounts into PackedAddressTreeInfo and PackedStateTreeInfo.
+ │  ├─ pack CompressedAccountMeta.
+ │  ├─ Build Instruction from PackedAccounts and CompressedAccountMetas.
+ │  └─ Send transaction.
+ │
+ └─ Custom Program
+    ├─ CpiAccounts parse accounts consistent with PackedAccounts.
+    ├─ LightAccount instantiates from CompressedAccountMeta.
+    │
+    └─ Light System Program CPI
+       ├─ Verify ValidityProof.
+       ├─ Update State Merkle tree.
+       ├─ Update Address Merkle tree.
+       └─ Complete atomic state transition.
+```
+
+## Features
+
+1. `anchor` - Derives AnchorSerialize, AnchorDeserialize instead of BorshSerialize, BorshDeserialize.
+
+2. `v2`
+    - available on devnet, localnet, and light-program-test.
+    - Support for optimized v2 light system program instructions.
+
+3. `cpi-context` - Enables CPI context operations for batched compressed account operations.
+   - available on devnet, localnet, and light-program-test.
+   - Enables the use of one validity proof across multiple cpis from different programs in one instruction.
+   - For example spending compressed tokens (owned by the ctoken program) and updating a compressed pda (owned by a custom program)
+     with one validity proof.
+   - An instruction should not use more than one validity proof.
+   - Requires the v2 feature.
+

+description: Query Light Protocol and related repositories via DeepWiki MCP. Use when answering questions about compressed accounts, Light SDK, Solana development, Claude Code features, or agent skills. Triggers on technical questions requiring repository context.
+---
+
+# DeepWiki Research
+
+Query repositories via DeepWiki MCP to answer technical questions with precise, source-backed answers.
+
+## Execution Steps
+
+### 1. Read Required Context
+
+Before answering any question:
+
+```bash
+cat /home/tilo/.claude/context/terminology-reference.md
+```
+
+### 2. Identify Question Scope
+
+Determine the domain:
+- Programs, client SDKs, architecture, implementation details
+- Specific components (LightAccount, ValidityProof, CPI, etc.)
+
+### 3. Fetch Repository Context
+
+Select the appropriate repository based on question scope:
+
+**Light Protocol (compressed accounts, state trees, ZK compression, Light SDK)**
+```
+mcp__deepwiki__read_wiki_structure("Lightprotocol/light-protocol")
+mcp__deepwiki__read_wiki_contents("Lightprotocol/light-protocol")
+mcp__deepwiki__ask_question("Lightprotocol/light-protocol", "your question")
+```
+
+**Solana Development (programs, accounts, general Solana)**
+```
+mcp__deepwiki__read_wiki_structure("blueshift-gg/blueshift-dashboard")
+mcp__deepwiki__read_wiki_contents("blueshift-gg/blueshift-dashboard")
+mcp__deepwiki__ask_question("blueshift-gg/blueshift-dashboard", "your question")
+```
+
+**Claude Code (CLI features, commands, configuration)**
+```
+mcp__deepwiki__read_wiki_structure("anthropics/claude-code")
+mcp__deepwiki__read_wiki_contents("anthropics/claude-code")
+mcp__deepwiki__ask_question("anthropics/claude-code", "your question")
+```
+
+**Agent Skills (skills, subagents, patterns)**
+```
+mcp__deepwiki__read_wiki_structure("anthropics/skills")
+mcp__deepwiki__read_wiki_contents("anthropics/skills")
+mcp__deepwiki__ask_question("anthropics/skills", "your question")
+```
+
+### 4. Apply Precision Rules
+
+**AVOID:**
+- Vague verbs: "handles", "manages", "processes", "enables", "provides"
+- Abstract nouns: "operations", "management", "coordination"
+- -ing endings when a precise verb exists
+- Marketing language: "comprehensive", "rich", "seamless"
+
+**USE:**
+- Exact function/method names
+- Concrete data structures
+- Specific operations: "sets discriminator", "creates hash", "nullifies account"
+- File:line references
+
+### 5. Format Response
+
+Structure answers with:
+- Technical precision
+- Code examples with inline comments
+- Source references (file paths, line numbers)
+
+## Example Output
+
+**Question:** What do you include in instruction data for compressed account creation?
+
+**Answer:**
+
+---
+
+## Compressed Account Creation Instruction Data
+
+Instruction data contains three components for proof verification and tree coordination.
+
+**Components:**
+
+```rust
+pub struct InstructionData {
+    proof: ValidityProof,
+    address_tree_info: PackedAddressTreeInfo,
+    output_state_tree_index: u8,
+    // + custom account data
+}
+```
+
+**1. Non-inclusion proof**
+- `ValidityProof` proves the derived address does not exist in the specified address tree
+- Client generates via `getValidityProof()` RPC call
+
+**2. Tree location parameters**
+- `PackedAddressTreeInfo`: Specifies which address tree registers the address (u8 index, not pubkey)
+- `output_state_tree_index`: Specifies which state tree stores the compressed account hash
+
+**3. Custom account data**
+- Program-specific fields (e.g., `message: String`, user data)
+
+**Execution flow:**
+
+1. Address tree proves uniqueness, stores address
+2. State tree stores account hash
+3. ValidityProof cryptographically guarantees address is unused
+
+**Why separate trees:**
+
+Compressed accounts require client-generated cryptographic proof that address doesn't exist (unlike regular Solana where runtime checks PDA existence). Address trees enforce uniqueness; state trees store account hashes.
+
+**Packed structs** use `u8` indices to reference accounts in `remaining_accounts`, reducing transaction size.

+# Light Token
+
+## Light Token SDK
+
+The base library to use Light Token Accounts, Light Mints, and compressed token accounts.
+
+### Light Token Accounts
+- are on Solana devnet.
+- are Solana accounts.
+- can hold tokens of Light, SPL and Token 2022 mints.
+- cost 17,288 lamports to create with 24 hours rent.
+- are rentfree:
+    - rent exemption is sponsored by the token program.
+    - rent is 388 lamports per rent epoch (1.5 hours).
+    - once the account's lamports balance is insufficient, it is auto-compressed to a compressed token account.
+    - the accounts state is cryptographically preserved on the Solana ledger.
+    - compressed tokens can be decompressed to a Light Token account.
+    - configurable lamports per write (eg transfer) keep the Light Token account perpetually funded when used. So you don't have to worry about funding rent.
+    - users load a compressed account into a light account in-flight when using the account again.
+
+### Light Mints
+- are on Solana devnet.
+- are Compressed accounts.
+- cost 15,000 lamports to create.
+- support `TokenMetadata`.
+- have the same rent-config as light token accounts
+

+
+### Endpoints
+
+| Service   | URL                                              |
+|-----------|--------------------------------------------------|
+| RPC       | `https://devnet.helius-rpc.com?api-key=` |
+| WebSocket | `wss://devnet.helius-rpc.com?api-key=`   |
+| Indexer   | `https://devnet.helius-rpc.com?api-key=` |
+| Prover    | `https://prover.helius.dev`                       |
+
+### Client Setup
+
+```typescript
+import { Rpc, createRpc } from "@lightprotocol/stateless.js";
+
+const HELIUS_API_KEY = process.env.HELIUS_API_KEY;
+
+const RPC_ENDPOINT = `https://devnet.helius-rpc.com?api-key=${HELIUS_API_KEY}`;
+const COMPRESSION_ENDPOINT = RPC_ENDPOINT;
+const PROVER_ENDPOINT = "https://prover.helius.dev";
+
+const connection: Rpc = createRpc(RPC_ENDPOINT, COMPRESSION_ENDPOINT, PROVER_ENDPOINT);
+
+// Fetch state trees at runtime
+const { stateTrees } = await connection.getCachedActiveStateTreeInfo();
+const outputStateTree = stateTrees[0].tree;
+```
+
+### Key Considerations
+
+- **Helius or Triton required**: The photon indexer implementation is maintained by Helius. You can also use Triton. Currently these RPC's provide compression endpoints
+- **Runtime tree fetch**: Always fetch active state trees at runtime via `getCachedActiveStateTreeInfo()`
+- **Same programs**: Program addresses are identical on devnet and mainnet
+- **Devnet-specific trees**: State tree lookup tables differ from mainnet
+
+### Devnet Addresses
+
+| Lookup Table                    | Address                                        |
+|---------------------------------|------------------------------------------------|
+| State Tree Lookup Table         | `DmRueT3LMJdGj3TEprqKtfwMxyNUHDnKrQua4xrqtbmG` |
+| Address Tree Lookup Table       | `G4HqCAWPJ1E3JmYX1V2RZvNMuzF6gcFdbwT8FccWX6ru` |
+
+Usage notes:
+
+- Always fetch state trees dynamically using `getCachedActiveStateTreeInfo()`
+- Do not hardcode tree addresses; they rotate as trees fill up
+- Lookup table addresses are stable and can be referenced directly
+
+## Rust Program Tests with light-program-test
+
+A fast local test environment for Solana programs using compressed accounts and tokens.
+
+**Use `light-program-test` when:**
+- You need fast test execution
+- You write unit/integration tests for your program or client code
+
+**Use `solana-test-validator` when:**
+- You need RPC methods or external tools that are incompatible with LiteSVM
+- Testing against real validator behavior
+
+### Prerequisites
+
+1. **ZK Compression CLI**: Required to start the prover server and download Light Protocol programs
+
+   ```bash
+   npm i -g @lightprotocol/zk-compression-cli
+   ```
+
+   If programs are missing after CLI installation, run `light test-validator` once to download them
+
+2. **Build programs**: Run `cargo test-sbf` to build program binaries and set the required
+   environment variables for locating program artifacts
+
+### Debugging
+
+Set `RUST_BACKTRACE=1` to show detailed transaction information including accounts and parsed instructions:
+
+```bash
+RUST_BACKTRACE=1 cargo test-sbf -- --nocapture
+```
+
+## Pre-initialized Accounts
+
+The test validator loads 39 pre-initialized accounts from the CLI's `accounts/` directory.

+# ZK Nullifiers
+
+Uses Compressed PDAs.
+
+## Overview
+
+Building a ZK Solana program requires:
+- Nullifiers to prevent double spending
+- Proof verification
+- A Merkle tree to store state
+- An indexer to serve Merkle proofs
+- Encrypted state
+
+## Nullifiers on Solana
+
+A nullifier is a deterministically derived hash to ensure an action can only be performed once. The nullifier cannot be linked to the action or user. For example Zcash uses nullifiers to prevent double spending.
+
+To implement nullifiers we need a data structure that ensures every nullifier is only created once and never deleted. On Solana a straight forward way to implement nullifiers is to create a PDA account with the nullifier as seed.
+
+PDA accounts cannot be closed and permanently lock 890,880 lamports (per nullifier rent-exemption).
+Compressed PDAs are derived similar to Solana PDAs and cost 15,000 lamports to create (no rent-exemption).
+
+| Storage | Cost per nullifier |
+|---------|-------------------|
+| PDA | 890,880 lamports |
+| Compressed PDA | 15,000 lamports |
+## When to Use Nullifiers
+
+## Pattern Overview
+
+```
+1. Client computes nullifier = hash(secret, context)
+2. Client fetches validity proof for derived address (proves it does not exist)
+3. Client calls create_nullifier with nullifier values and proof
+4. Program derives address from nullifier, creates compressed account via CPI
+5. Light system program rejects CPI if address already exists
+```
+
+## Reference Implementation
+
+Source: [program-examples/zk/nullifier](https://github.com/Lightprotocol/program-examples/tree/main/zk/nullifier)
+
+### Account Structure
+
+```rust
+#[derive(Clone, Debug, Default, BorshSerialize, BorshDeserialize, LightDiscriminator)]
+pub struct NullifierAccount {}
+```
+
+Empty struct since existence alone proves the nullifier was used.
+
+### Address Derivation
+
+```rust
+pub const NULLIFIER_PREFIX: &[u8] = b"nullifier";
+
+let (address, address_seed) = derive_address(
+    &[NULLIFIER_PREFIX, nullifier.as_slice()],  // seeds
+    &address_tree_pubkey,                        // address tree
+    &program_id,                                 // program ID
+);
+```
+
+Address is deterministically derived from:
+- Constant prefix (prevents collisions with other account types)
+- Nullifier value (32 bytes)
+- Address tree pubkey
+- Program ID
+
+### Instruction Data
+
+```rust
+#[derive(Clone, Debug, AnchorSerialize, AnchorDeserialize)]
+pub struct NullifierInstructionData {
+    pub proof: ValidityProof,           // ZK proof that addresses don't exist
+    pub address_tree_info: PackedAddressTreeInfo,
+    pub output_state_tree_index: u8,
+    pub system_accounts_offset: u8,
+}
+```
+
+### Create Nullifiers Function
+
+```rust
+pub fn create_nullifiers<'info>(
+    nullifiers: &[[u8; 32]],
+    data: NullifierInstructionData,
+    signer: &AccountInfo<'info>,
+    remaining_accounts: &[AccountInfo<'info>],
+) -> Result<()> {
+    let light_cpi_accounts = CpiAccounts::new(
+        signer,
+        &remaining_accounts[data.system_accounts_offset as usize..],
+        LIGHT_CPI_SIGNER,
+    );
+
+    let address_tree_pubkey = data
+        .address_tree_info
+        .get_tree_pubkey(&light_cpi_accounts)
+        .map_err(|_| ErrorCode::AccountNotEnoughKeys)?;
+
+    let mut cpi_builder = LightSystemProgramCpi::new_cpi(LIGHT_CPI_SIGNER, data.proof);
+    let mut new_address_params: Vec =
+        Vec::with_capacity(nullifiers.len());
+
+    for (i, nullifier) in nullifiers.iter().enumerate() {
+        let (address, address_seed) = derive_address(
+            &[NULLIFIER_PREFIX, nullifier.as_slice()],
+            &address_tree_pubkey,
+            &crate::ID,
+        );
+
+        let nullifier_account = LightAccount::::new_init(
+            &crate::ID,
+            Some(address),
+            data.output_state_tree_index,
+        );
+
+        cpi_builder = cpi_builder.with_light_account(nullifier_account)?;
+        new_address_params.push(
+            data.address_tree_info
+                .into_new_address_params_assigned_packed(address_seed, Some(i as u8)),
+        );
+    }
+
+    cpi_builder
+        .with_new_addresses(&new_address_params)
+        .invoke(light_cpi_accounts)?;
+
+    Ok(())
+}
+```
+
+### Program Entry Point
+
+```rust
+#[program]
+pub mod nullifier {
+    pub fn create_nullifier<'info>(
+        ctx: Context<'_, '_, '_, 'info, CreateNullifierAccounts<'info>>,
+        data: NullifierInstructionData,
+        nullifiers: Vec<[u8; 32]>,
+    ) -> Result<()> {
+        // Verify your ZK proof here. Use nullifiers as public inputs.
+        // Example:
+        // let public_inputs = [...nullifiers, ...your_other_inputs];
+        // Groth16Verifier::new(...).verify()?;
+
+        create_nullifiers(
+            &nullifiers,
+            data,
+            ctx.accounts.signer.as_ref(),
+            ctx.remaining_accounts,
+        )
+    }
+}
+
+#[derive(Accounts)]
+pub struct CreateNullifierAccounts<'info> {
+    #[account(mut)]
+    pub signer: Signer<'info>,
+}
+```
+
+## Client Implementation (TypeScript)
+
+```typescript
+const NULLIFIER_PREFIX = Buffer.from("nullifier");
+const addressTree = new web3.PublicKey(batchAddressTree);
+
+// Derive addresses for each nullifier
+const addressesWithTree = nullifiers.map((nullifier) => {
+    const seed = deriveAddressSeedV2([NULLIFIER_PREFIX, nullifier]);
+    const address = deriveAddressV2(seed, addressTree, programId);
+    return { tree: addressTree, queue: addressTree, address: bn(address.toBytes()) };
+});
+
+// Get validity proof (proves addresses don't exist)
+const proofResult = await rpc.getValidityProofV0([], addressesWithTree);
+
+// Build remaining accounts
+const remainingAccounts = new PackedAccounts();
+remainingAccounts.addSystemAccountsV2(SystemAccountMetaConfig.new(programId));
+const addressMerkleTreeIndex = remainingAccounts.insertOrGet(addressTree);
+const outputStateTreeIndex = remainingAccounts.insertOrGet(outputStateTree);
+
+// Build instruction data
+const data = {
+    proof: { 0: proofResult.compressedProof },
+    addressTreeInfo: {
+        addressMerkleTreePubkeyIndex: addressMerkleTreeIndex,
+        addressQueuePubkeyIndex: addressMerkleTreeIndex,
+        rootIndex: proofResult.rootIndices[0],
+    },
+    outputStateTreeIndex,
+    systemAccountsOffset: systemStart,
+};
+
+// Call program
+const ix = await program.methods
+    .createNullifier(data, nullifiers.map((n) => Array.from(n)))
+    .accounts({ signer: signer.publicKey })
+    .remainingAccounts(remainingAccounts)
+    .instruction();
+```
+
+## Client Implementation (Rust)
+
+```rust
+use light_sdk::address::v2::derive_address;
+
+let address_tree_info = rpc.get_address_tree_v2();
+
+// Derive addresses
+let address_with_trees: Vec = nullifiers
+    .iter()
+    .map(|n| {
+        let (address, _) = derive_address(
+            &[NULLIFIER_PREFIX, n.as_slice()],
+            &address_tree_info.tree,
+            &program_id,
+        );
+        AddressWithTree {
+            address,
+            tree: address_tree_info.tree,
+        }
+    })
+    .collect();
+
+// Get validity proof (empty hashes = non-inclusion proof)
+let rpc_result = rpc
+    .get_validity_proof(vec![], address_with_trees, None)
+    .await?
+    .value;
+
+// Build accounts
+let mut remaining_accounts = PackedAccounts::default();
+let config = SystemAccountMetaConfig::new(program_id);
+remaining_accounts.add_system_accounts_v2(config)?;
+
+let packed_address_tree_accounts = rpc_result
+    .pack_tree_infos(&mut remaining_accounts)
+    .address_trees;
+
+let output_state_tree_index = rpc
+    .get_random_state_tree_info()?
+    .pack_output_tree_index(&mut remaining_accounts)?;
+```
+
+## How Nullifier Trees Work
+
+Light Protocol uses indexed Merkle trees for nullifiers (address trees). When creating a nullifier:
+
+1. Program derives a deterministic address from nullifier value
+2. Validity proof proves this address does NOT exist in the tree
+3. Light system program inserts the address into the tree
+4. Future attempts fail because address now exists
+
+The indexed Merkle tree structure allows efficient non-inclusion proofs. Each leaf contains not just its value but also a pointer to the next-highest value, enabling proofs that a value falls between two existing values.
+
+## Dependencies

+## Light Token
+
+Light token is a high-performance token standard that reduces the cost of mint and token accounts by 200x.
+
+* All light mint and token accounts are on-chain accounts like SPL, but the light token program sponsors the rent-exemption cost for you.
+* Light-token accounts can hold balances from any light, SPL, or Token-2022 mint.
+* Light-mint accounts represent a unique mint and optionally can store token-metadata. Functionally equivalent to SPL mints.

+Compressed Token Accounts
+- are well suited for airdrops and reward distribution.
+- require no rent-exemption
+- are on Solana mainnet.
+- are compressed accounts (similar UX to SPL)
+- can hold Light Mint and SPL Mint tokens.

+- Wallet support by Phantom and Backpack
+
+### Difference to Light-Token
+light-token: Solana account that holds token balances of light-mints, SPL or Token 22 mints.

+## Compressed PDAs
+
+Compressed accounts do not require rent-exemption, which makes them suitable for:
+- user owned accounts
+- not config accounts which are often read
+- not pool accounts, since compressed accounts cannot be used concurrently
+
+Load skill: [Full reference](references/compressed-pda.md)
+
+### Difference to Light-Accounts (Light-PDA)
+Light-PDA's are Solana accounts with sponsored rent-exemption.
+There is no proof required for interactions with Light-PDA's which makes
+them suitable for Defi Usecases. Compressed PDA's don't require rent-exemption,
+but a proof for interactions.
+
+### Client-Program Interaction Flow
+```text
+ ├─ Client
+ │  ├─ Get ValidityProof from RPC.
+ │  ├─ pack accounts with PackedAccounts into PackedAddressTreeInfo and PackedStateTreeInfo.
+ │  ├─ pack CompressedAccountMeta.
+ │  ├─ Build Instruction from PackedAccounts and CompressedAccountMetas.
+ │  └─ Send transaction.
+ │
+ └─ Custom Program
+    ├─ CpiAccounts parse accounts consistent with PackedAccounts.
+    ├─ LightAccount instantiates from CompressedAccountMeta.
+    │
+    └─ Light System Program CPI
+       ├─ Verify ValidityProof.
+       ├─ Update State Merkle tree.
+       ├─ Update Address Merkle tree.
+       └─ Complete atomic state transition.

-# Airdrop
-
-Distribute compressed tokens to multiple recipients using TypeScript client.
-
-## Quick Decision
-
-| Scale | Approach |
-|-------|----------|
-| <10,000 recipients | Single transaction - see [Simple Airdrop](#simple-airdrop-10000-recipients) |
-| 10,000+ recipients | Batched with retry - see [Batched Airdrop](#batched-airdrop-10000-recipients) |
-| No-code | [Airship by Helius](https://airship.helius.dev/) (up to 200k) |
-
-## Core Pattern
-
-```typescript
-import { CompressedTokenProgram, getTokenPoolInfos, selectTokenPoolInfo } from "@lightprotocol/compressed-token";
-import { bn, createRpc, selectStateTreeInfo, buildAndSignTx, sendAndConfirmTx } from "@lightprotocol/stateless.js";
-import { ComputeBudgetProgram } from "@solana/web3.js";
-
-const rpc = createRpc(RPC_ENDPOINT);
-
-// 1. Get infrastructure
-const treeInfo = selectStateTreeInfo(await rpc.getStateTreeInfos());
-const tokenPoolInfo = selectTokenPoolInfo(await getTokenPoolInfos(rpc, mint));
-
-// 2. Build compress instruction (SPL -> compressed to multiple recipients)
-const ix = await CompressedTokenProgram.compress({
-  payer: payer.publicKey,
-  owner: payer.publicKey,
-  source: sourceAta.address,           // SPL ATA holding tokens
-  toAddress: recipients,                // PublicKey[]
-  amount: recipients.map(() => bn(amount)),
-  mint,
-  tokenPoolInfo,
-  outputStateTreeInfo: treeInfo,
-});
-
-// 3. Send with compute budget (120k CU per recipient)
-const instructions = [
-  ComputeBudgetProgram.setComputeUnitLimit({ units: 120_000 * recipients.length }),
-  ix,
-];
-const { blockhash } = await rpc.getLatestBlockhash();
-const tx = buildAndSignTx(instructions, payer, blockhash, []);
-await sendAndConfirmTx(rpc, tx);
-```
-
-## Setup: Create Mint
-
-```typescript
-import { createMint } from "@lightprotocol/compressed-token";
-import { getOrCreateAssociatedTokenAccount, mintTo } from "@solana/spl-token";
-
-const { mint } = await createMint(rpc, payer, payer.publicKey, 9);
-const ata = await getOrCreateAssociatedTokenAccount(rpc, payer, mint, payer.publicKey);
-await mintTo(rpc, payer, mint, ata.address, payer.publicKey, 100_000_000_000);
-```
-
-## Compute Units
-
-| Recipients/instruction | CU |
-|----------------------|-----|
-| 1 | 120,000 |
-| 5 | 170,000 |
-| Batched tx | 500,000 |
-
-## Lookup Tables
-
-Reduce transaction size:
-
-| Network | Address |
-|---------|---------|
-| Mainnet | `9NYFyEqPkyXUhkerbGHXUXkvb4qpzeEdHuGpgbgpH1NJ` |
-| Devnet | `qAJZMgnQJ8G6vA3WRcjD9Jan1wtKkaCFWLWskxJrR5V` |
-
-## Simple Airdrop (<10,000 recipients)
-
-Single transaction approach for small distributions.
-
-```typescript
-import {
-  CompressedTokenProgram,
-  getTokenPoolInfos,
-  selectTokenPoolInfo,
-} from "@lightprotocol/compressed-token";
-import {
-  bn,
-  buildAndSignTx,
-  calculateComputeUnitPrice,
-  createRpc,
-  dedupeSigner,
-  selectStateTreeInfo,
-  sendAndConfirmTx,
-} from "@lightprotocol/stateless.js";
-import { ComputeBudgetProgram, Keypair, PublicKey } from "@solana/web3.js";
-import { getOrCreateAssociatedTokenAccount } from "@solana/spl-token";
-
-const RPC_ENDPOINT = "https://devnet.helius-rpc.com?api-key=YOUR_KEY";
-const rpc = createRpc(RPC_ENDPOINT);
-const mint = new PublicKey("YOUR_MINT_ADDRESS");
-
-// Define recipients and amounts
-const recipients = [
-  new PublicKey("..."),
-  new PublicKey("..."),
-  new PublicKey("..."),
-];
-
-const amounts = [
-  bn(20_000_000_000), // 20 tokens (9 decimals)
-  bn(30_000_000_000), // 30 tokens
-  bn(40_000_000_000), // 40 tokens
-];
-
-// Get infrastructure
-const treeInfo = selectStateTreeInfo(await rpc.getStateTreeInfos());
-const tokenPoolInfo = selectTokenPoolInfo(await getTokenPoolInfos(rpc, mint));
-const sourceAta = await getOrCreateAssociatedTokenAccount(rpc, payer, mint, payer.publicKey);
-
-// Build transaction
-const units = 120_000 * recipients.length;
-const instructions = [
-  ComputeBudgetProgram.setComputeUnitLimit({ units }),
-  ComputeBudgetProgram.setComputeUnitPrice({
-    microLamports: calculateComputeUnitPrice(20_000, units),
-  }),
-  await CompressedTokenProgram.compress({
-    payer: payer.publicKey,
-    owner: payer.publicKey,
-    source: sourceAta.address,
-    toAddress: recipients,
-    amount: amounts,
-    mint,
-    tokenPoolInfo,
-    outputStateTreeInfo: treeInfo,
-  }),
-];
-
-// Use lookup table to reduce tx size
-const lut = new PublicKey("9NYFyEqPkyXUhkerbGHXUXkvb4qpzeEdHuGpgbgpH1NJ"); // mainnet
-// const lut = new PublicKey("qAJZMgnQJ8G6vA3WRcjD9Jan1wtKkaCFWLWskxJrR5V"); // devnet
-const lookupTable = (await rpc.getAddressLookupTable(lut)).value!;
-
-const { blockhash } = await rpc.getLatestBlockhash();
-const tx = buildAndSignTx(
-  instructions,
-  payer,
-  blockhash,
-  dedupeSigner(payer, []),
-  [lookupTable]
-);
-const txId = await sendAndConfirmTx(rpc, tx);
-console.log(`Airdrop complete: ${txId}`);
-```
-
-### Verify Distribution
-
-```typescript
-for (const recipient of recipients) {
-  const accounts = await rpc.getCompressedTokenAccountsByOwner(recipient, { mint });
-  const balance = accounts.items.reduce((sum, acc) => sum + Number(acc.parsed.amount), 0);
-  console.log(`${recipient}: ${balance / 1e9} tokens`);
-}
-```
-
-## Batched Airdrop (10,000+ recipients)
-
-For large-scale distributions with retry logic and blockhash management.

-description: Query Light Protocol and related repositories via DeepWiki MCP. Use when answering questions about compressed accounts, Light SDK, Solana development, Claude Code features, or agent skills. Triggers on technical questions requiring repository context.
----
-
-# DeepWiki Research
-
-Query repositories via DeepWiki MCP to answer technical questions with precise, source-backed answers.
-
-## Execution Steps
-
-### 1. Read Required Context
-
-Before answering any question:
-
-```bash
-cat /home/tilo/.claude/context/terminology-reference.md
-```
-
-### 2. Identify Question Scope
-
-Determine the domain:
-- Programs, client SDKs, architecture, implementation details
-- Specific components (LightAccount, ValidityProof, CPI, etc.)
-
-### 3. Fetch Repository Context
-
-Select the appropriate repository based on question scope:
-
-**Light Protocol (compressed accounts, state trees, ZK compression, Light SDK)**
-```
-mcp__deepwiki__read_wiki_structure("Lightprotocol/light-protocol")
-mcp__deepwiki__read_wiki_contents("Lightprotocol/light-protocol")
-mcp__deepwiki__ask_question("Lightprotocol/light-protocol", "your question")
-```
-
-**Solana Development (programs, accounts, general Solana)**
-```
-mcp__deepwiki__read_wiki_structure("blueshift-gg/blueshift-dashboard")
-mcp__deepwiki__read_wiki_contents("blueshift-gg/blueshift-dashboard")
-mcp__deepwiki__ask_question("blueshift-gg/blueshift-dashboard", "your question")
-```
-
-**Claude Code (CLI features, commands, configuration)**
-```
-mcp__deepwiki__read_wiki_structure("anthropics/claude-code")
-mcp__deepwiki__read_wiki_contents("anthropics/claude-code")
-mcp__deepwiki__ask_question("anthropics/claude-code", "your question")
-```
-
-**Agent Skills (skills, subagents, patterns)**
-```
-mcp__deepwiki__read_wiki_structure("anthropics/skills")
-mcp__deepwiki__read_wiki_contents("anthropics/skills")
-mcp__deepwiki__ask_question("anthropics/skills", "your question")
-```
-
-### 4. Apply Precision Rules
-
-**AVOID:**
-- Vague verbs: "handles", "manages", "processes", "enables", "provides"
-- Abstract nouns: "operations", "management", "coordination"
-- -ing endings when a precise verb exists
-- Marketing language: "comprehensive", "rich", "seamless"
-
-**USE:**
-- Exact function/method names
-- Concrete data structures
-- Specific operations: "sets discriminator", "creates hash", "nullifies account"
-- File:line references
-
-### 5. Format Response
-
-Structure answers with:
-- Technical precision
-- Code examples with inline comments
-- Source references (file paths, line numbers)
-
-## Example Output
-
-**Question:** What do you include in instruction data for compressed account creation?
-
-**Answer:**
-
----
-
-## Compressed Account Creation Instruction Data
-
-Instruction data contains three components for proof verification and tree coordination.
-
-**Components:**
-
-```rust
-pub struct InstructionData {
-    proof: ValidityProof,
-    address_tree_info: PackedAddressTreeInfo,
-    output_state_tree_index: u8,
-    // + custom account data
-}
-```
-
-**1. Non-inclusion proof**
-- `ValidityProof` proves the derived address does not exist in the specified address tree
-- Client generates via `getValidityProof()` RPC call
-
-**2. Tree location parameters**
-- `PackedAddressTreeInfo`: Specifies which address tree registers the address (u8 index, not pubkey)
-- `output_state_tree_index`: Specifies which state tree stores the compressed account hash
-
-**3. Custom account data**
-- Program-specific fields (e.g., `message: String`, user data)
-
-**Execution flow:**
-
-1. Address tree proves uniqueness, stores address
-2. State tree stores account hash
-3. ValidityProof cryptographically guarantees address is unused
-
-**Why separate trees:**
-
-Compressed accounts require client-generated cryptographic proof that address doesn't exist (unlike regular Solana where runtime checks PDA existence). Address trees enforce uniqueness; state trees store account hashes.
-
-**Packed structs** use `u8` indices to reference accounts in `remaining_accounts`, reducing transaction size.

-### Common Operations
-
-| Operation | Instruction Builder | CPI Builder |
-|-----------|----------------|-------------|
-| Create Associated Token Account | `CreateAssociatedTokenAccount` | `CreateAssociatedAccountCpi` |
-| Create Token Account | `CreateTokenAccount` | `CreateTokenAccountCpi` |
-| Transfer | `Transfer` | `TransferCpi` |
-| Transfer Interface (auto-detect) | `TransferInterface` | `TransferInterfaceCpi` |
-| Close Token account | `CloseAccount` | `CloseAccountCpi` |
-| Create Mint | `CreateMint` | `CreateMintCpi` |
-| MintTo | `MintTo` | `MintToCpi` |
-
-### Features
-
-1. `anchor` - Derives AnchorSerialize, AnchorDeserialize instead of BorshSerialize, BorshDeserialize.
-2. `compressible` - utility functions for compressible sdk macros.
+### Instructions
+
+The instructions use pure CPI calls which you can combine with existing and / or light macros.
+For existing programs, you can replace spl_token with light_token instructions as you need. The API is a superset of SPL-token so switching is straightforward.

-## Light Token
-
-Light token is a high-performance token standard that reduces the cost of mint and token accounts by 200x.
-
-* All light mint and token accounts are on-chain accounts like SPL, but the light token program sponsors the rent-exemption cost for you.
-* Light-token accounts can hold balances from any light, SPL, or Token-2022 mint.
-* Light-mint accounts represent a unique mint and optionally can store token-metadata. Functionally equivalent to SPL mints.

-Compressed Token Accounts
-- are well suited for airdrops and reward distribution.
-- require no rent-exemption
-- are on Solana mainnet.
-- are compressed accounts (similar UX to SPL)
-- can hold Light Mint and SPL Mint tokens.
-- cost 5,000 lamports to create.
-- Wallet support by Phantom and Backpack
-
-### Difference to Light-Token
-light-token: Solana account that holds token balances of light-mints, SPL or Token 22 mints.
-Compressed token: Compressed account storing token data. Rent-free, for storage and distribution.

-## Compressed PDAs
-
-Compressed accounts do not require rent-exemption, which makes them suitable for:
-- user owned accounts
-- not config accounts which are often read
-- not pool accounts, since compressed accounts cannot be used concurrently
-
-Load skill: [Full reference](references/compressed-pda.md)
-
-### Difference to Light-Accounts (Light-PDA)
-Light-PDA's are Solana accounts with sponsored rent-exemption.
-There is no proof required for interactions with Light-PDA's which makes
-them suitable for Defi Usecases. Compressed PDA's don't require rent-exemption,
-but a proof for interactions.
-
-### Client-Program Interaction Flow
-```text
- ├─ Client
- │  ├─ Get ValidityProof from RPC.
- │  ├─ pack accounts with PackedAccounts into PackedAddressTreeInfo and PackedStateTreeInfo.
- │  ├─ pack CompressedAccountMeta.
- │  ├─ Build Instruction from PackedAccounts and CompressedAccountMetas.
- │  └─ Send transaction.
- │
- └─ Custom Program
-    ├─ CpiAccounts parse accounts consistent with PackedAccounts.
-    ├─ LightAccount instantiates from CompressedAccountMeta.

-## ZK Nullifiers
-
-[Full reference](references/zk-nullifiers.md)
-
-Use for privacy preserving applications on Solana to prevent double spending. Uses compressed PDAs as nullifiers. A nullifier is a deterministically derived hash to ensure an action can only be performed once. The nullifier cannot be linked to the action or user.
-
-| Storage | Cost per nullifier |
-|---------|-------------------|
-| PDA | 890,880 lamports |
-| Compressed PDA | 15,000 lamports |

+### Instructions
+
+The instructions use pure CPI calls which you can combine with existing and / or light macros.
+For existing programs, you can replace spl_token with light_token instructions as you need. The API is a superset of SPL-token so switching is straightforward.
+
+|  | Description |
+|---------|-------------|
+| [approve](https://github.com/Lightprotocol/examples-light-token/blob/main/programs/anchor/basic-instructions/approve/src/lib.rs) | Approve delegate via CPI |
+| [burn](https://github.com/Lightprotocol/examples-light-token/blob/main/programs/anchor/basic-instructions/burn/src/lib.rs) | Burn tokens via CPI |
+| [close](https://github.com/Lightprotocol/examples-light-token/blob/main/programs/anchor/basic-instructions/close/src/lib.rs) | Close token account via CPI |

+| [freeze](https://github.com/Lightprotocol/examples-light-token/blob/main/programs/anchor/basic-instructions/freeze/src/lib.rs) | Freeze token account via CPI |
+| [mint-to](https://github.com/Lightprotocol/examples-light-token/blob/main/programs/anchor/basic-instructions/mint-to/src/lib.rs) | Mint tokens via CPI |
+| [revoke](https://github.com/Lightprotocol/examples-light-token/blob/main/programs/anchor/basic-instructions/revoke/src/lib.rs) | Revoke delegate via CPI |
+| [thaw](https://github.com/Lightprotocol/examples-light-token/blob/main/programs/anchor/basic-instructions/thaw/src/lib.rs) | Thaw token account via CPI |
+| [transfer-checked](https://github.com/Lightprotocol/examples-light-token/blob/main/programs/anchor/basic-instructions/transfer-checked/src/lib.rs) | Transfer with mint validation via CPI |
+| [transfer-interface](https://github.com/Lightprotocol/examples-light-token/blob/main/programs/anchor/basic-instructions/transfer-interface/src/lib.rs) | Transfer between light-token, T22, and SPL accounts via CPI |
+
+### Macros

+
+### Examples
+
+|  | Description |
+|---------|-------------|
+| [cp-swap-reference](https://github.com/Lightprotocol/cp-swap-reference) | Fork of Raydium AMM that creates markets without paying rent-exemption |

+The state is cryptographically preserved on the Solana ledger.
 While compressed, pure on-chain lookups will return uninitialized.
