> ## Agent Instructions
> SODAX is mainnet-only (no testnet chains or RPC endpoints exist) with a hub-and-spoke architecture; Sonic is the hub. SODAX is non-custodial protocol/software: it routes and settles; independent solvers on the marketplace fill — never say 'our solver', 'the SODAX solver', that SODAX trades, takes custody, or fills orders. For frontend/React integrations, prefer @sodax/dapp-kit hooks over calling @sodax/sdk directly. SDK operations — the methods that build, submit or await a transaction, and the API/quote calls — return Result<T, E> ({ ok: true, value } or { ok: false, error }): check result.ok, never wrap them in try/catch or branch on error.message; discriminate on the narrow error.code union instead. Synchronous config getters (getPartnerFee, getSupportedSwapTokens, getVault, ...) return their value directly, not a Result.

# Avalanche Wallets

> EVM wallets on Avalanche, and every other network's wallets through one interface, with @sodax/wallet-sdk-react or a direct provider.

Welcoming cross-network users means supporting the wallets they already use. On Avalanche, SODAX works with any wallet that can sign EVM transactions on the C-Chain (chain ID 43114), such as MetaMask. On the networks your users arrive from, it is Phantom, Suiet, Lobstr, and more. SODAX gives you both through one interface, so wallet plumbing never becomes the integration.

Nothing about Avalanche wallets is SODAX-specific: a wallet connected to the C-Chain is all you need.

## React apps: `@sodax/wallet-sdk-react`

The React package wraps each chain family's native wallet SDK (wagmi for EVM networks, including Avalanche) behind a uniform connector interface with a single persisted store.

```bash theme={null}
pnpm add @sodax/wallet-sdk-react
```

Mount the provider with the chains you serve. Avalanche is an entry under `EVM`, alongside any other EVM network you support:

```tsx theme={null}
import { SodaxWalletProvider, type SodaxWalletConfig } from '@sodax/wallet-sdk-react';
import { ChainKeys } from '@sodax/types';

const config: SodaxWalletConfig = {
  EVM: {
    chains: {
      [ChainKeys.AVALANCHE_MAINNET]: { rpcUrl: 'https://api.avax.network/ext/bc/C/rpc' },
      [ChainKeys.SONIC_MAINNET]: { rpcUrl: 'https://rpc.soniclabs.com' },
    },
  },
};
```

Then connect and read accounts with the same three hooks for every chain family:

```tsx theme={null}
import { useXConnectors, useXConnect, useXAccount } from '@sodax/wallet-sdk-react';

function EvmConnect() {
  const connectors = useXConnectors({ xChainType: 'EVM' }); // MetaMask, Rabby, ...
  const { mutateAsync: connect } = useXConnect();
  const account = useXAccount({ xChainType: 'EVM' });

  if (account.address) return <p>Connected: {account.address}</p>;

  return connectors.map(c => (
    <button key={c.id} onClick={() => connect(c)}>{c.name}</button>
  ));
}
```

One EVM connection covers every EVM network, so the wallet may be on a different network than Avalanche when your user acts. `useEvmSwitchChain({ xChainId: ChainKeys.AVALANCHE_MAINNET })` returns `isWrongChain` and a `handleSwitchChain` callback to prompt the switch.

### Bridging to SDK calls

`useWalletProvider({ xChainId: ChainKeys.AVALANCHE_MAINNET })` returns a typed `IEvmWalletProvider` ready to pass into any `@sodax/sdk` method. The [swap](/avalanche/swaps) and [money market](/avalanche/money-market) calls take it directly.

## Scripts and backends: `EvmWalletProvider`

Outside React, construct the provider from `@sodax/wallet-sdk-core` directly:

```typescript theme={null}
import { EvmWalletProvider } from '@sodax/wallet-sdk-core';
import { ChainKeys } from '@sodax/sdk';

const walletProvider = new EvmWalletProvider({
  privateKey: '0x…', // private key of the C-Chain account
  chainId: ChainKeys.AVALANCHE_MAINNET,
  rpcUrl: 'https://api.avax.network/ext/bc/C/rpc',
});
```

`EvmWalletDefaults` lets you tune behavior per provider: `sendTransaction`, `waitForTransactionReceipt`, `publicClient`, `walletClient`, and `transport`.
