Deploying Smart Wallets

The Swaps API uses smart contract wallets (account abstraction) to manage user funds and execute transactions. Before placing orders, your smart wallet must be deployed on-chain.

​

Smart Wallet Address

Your smart wallet address is deterministically computed from your EOA (Externally Owned Account) address. This means:

• The same EOA always produces the same smart wallet address
• The address can be computed before deployment
• No need to wait for deployment to know your wallet address

​

Deployment Process

Deployment is a one-time process per chain:

1. Get Sign Request - Request a typed data message for deployment
   • The message includes permission settings for session keys
   • Specifies which chain to deploy on
2. Sign Message - Sign the typed data with your EOA wallet
   • This proves you own the EOA and authorize the deployment
3. Deploy - Submit the signed message to deploy the wallet contract
   • The smart wallet contract is deployed on-chain
   • Session keys are configured for gasless transactions
   • Deployment is tracked in the system

​

After Deployment

Once deployed, your smart wallet can:

• Hold USDC for buy orders
• Hold ERC-1155 tokens for sell orders
• Execute on-chain transactions automatically
• Use session keys for gasless operations

​

Multi-Chain Support

Each chain requires a separate deployment. The system tracks which chains your wallet is deployed on, so you can deploy to multiple chains as needed.
