# Cross-chain transactions

For EVM wallets, you can create transactions on any supported EVM chain where you have a balance. Use the `blockchain` parameter to specify which chain to transact on.

## Creating a cross-chain withdrawal

When creating a transfer from an EVM wallet, include the optional `blockchain` parameter to specify the target chain:


```
POST /v2/vaults/{vault_id}/wallets/{wallet_id}/transactions/transfer
{
  "destination_address": "0x...",
  "symbol": "USDC",
  "quantity": "100",
  "blockchain": "ARBITRUM"
}
```

Default behavior
If no `blockchain` parameter is provided for an EVM wallet, the transaction defaults the wallet `blockchain`.

EVM only
The `blockchain` parameter only applies to EVM wallets. Using it with non-EVM wallets will return an error.
