+# Sprinter React SDK
+
+The Sprinter React SDK is a React wrapper for the [Sprinter SDK](https://github.com/ChainSafe/sprinter-sdk), enabling easy interaction with blockchain networks through React components and hooks. It provides context management and custom hooks for retrieving balances, tokens, supported chains, and solutions for asset transfers.
+
+## Installation
+
+To install the package, use npm or yarn:
+
+```bash
+npm install @chainsafe/sprinter-react
+# or
+yarn add @chainsafe/sprinter-react
+```
+
+## Usage
+
+Wrap your application in the `SprinterContext` to gain access to blockchain-related data within your component tree.
+
+### Example
+
+```tsx
+import React from 'react';
+import { SprinterContext } from '@chainsafe/sprinter-react';
+
+const App = () => (
+  <SprinterContext>
+    <YourComponent />
+  </SprinterContext>
+);
+
+export default App;
+```
+
+Inside your components, you can use the provided hooks to interact with blockchain data:
+
+```tsx
+import React, { useEffect } from 'react';
+import { useSprinterBalances, useSprinterTokens } from '@chainsafe/sprinter-react';
+
+const YourComponent = () => {
+  const ownerAddress = "0xYourAddressHere";
+  const { balances, getUserBalances } = useSprinterBalances(ownerAddress);
+
+  useEffect(() => {
+    getUserBalances();
+  }, [getUserBalances]);
+
+  return (
+    <div>
+      <h1>Balances:</h1>
+      <pre>{JSON.stringify(balances, null, 2)}</pre>
+      <h1>Available Tokens:</h1>
+      <pre>{JSON.stringify(tokens, null, 2)}</pre>
+    </div>
+  );
+};
+
+export default YourComponent;
+```
+
+### Available Hooks
+
+The following hooks are provided by the SDK:
+
+- **`useSprinter()`**: Access everything from the Sprinter context.
+- **`useSprinterBalances(account: Address)`**: Retrieve user balances for a given account.
+- **`useSprinterTokens()`**: Retrieve available tokens.
+- **`useSprinterChains()`**: Retrieve available blockchain chains.
+- **`useSprinterSolution()`**: Retrieve solutions for asset transfers.
+- **`useSprinterCallSolution()`**: Call solutions for transferring assets.
+
+### Custom Fetch Options
+
+You can pass custom fetch options when initializing the context:
+
+```tsx
+<SprinterContext fetchOptions={{ baseUrl: "https://api.test.sprinter.buildwithsygma.com/" }}>
+  <YourComponent />
+</SprinterContext>
+```
