[CHECKLIST] Relayer event listeners and handlers for MASP

[dev0x1]

Overview

This checklist contains all tasks relevant for the relayer to get the MASP delivered on the relayer side. It includes

• transaction relaying of regular MASP transactions
• roots updating and governance proposals execution
• batch update processing by a relayer
• swap relayer tasks
• (for the future) delegated proof generation (which likely will be subsumed by zkSaaS or SGX node.

Tx relaying tasks (similar to existing flow)

• [TASK] Transaction Relaying: Create API Method #427
• [TASK] Transaction Relaying: Tests #428
• [TASK] Add documentation + diagrams of MASP tx relaying #586

Roots relaying tasks + governance

• [TASK] Roots relaying handler + event listener for MASP transaction tree #587
• [TASK] Roots relaying handler + event listener for SpentTrees #588
• [TASK] Roots relaying handler + event listener for UnspentTree #589
• [TASK] Tests for signed proposal execution of governance proposals #590

Batch relayer tasks

• [TASK] Batch Deposit Relaying for tx + reward trees: Event Listener #438
• [TASK] Batch Deposit Relaying: Tests #436
• [TASK] Batch Reward Tree Processing: Tests #439
• [TASK] Create Batched Deposit Processing diagram #423
• [TASK] Write Batched Deposit Processing documentation #422
• [TASK] Write Batched Reward Tree Processing documentation #426

Swap relayer tasks

• [TASK] Swap Relaying: Create API Method #429
• [TASK] Swap Relaying: Add validation and edge-case checking of proof inputs #430
• [TASK] Swap relaying: Generate swap proof #431
• [TASK] Swap Relaying: Tests #432
• [TASK] Write Swap Relayer Documentation #419

Future (delegated proof gen)

This is likely not a high priority

• [TASK] Delegatable Proof Generation: Create API endpoint #440
• [TASK] Delegatable proof generation: Tests #444
• [TASK] Delegatable Proof Generation: Add validation and edge-case checking of proof inputs #442
• [TASK] Write Delegatable Proof Generation documentation #420
