How wallets work in production
Integrate the SDK into your app to create wallets, choose custody, generate and confirm shares, then execute transactions with optional gas sponsorship.
Provision client and session
Create a Smart Wallet client in your app and issue a short-lived session token for authenticated wallet actions through the SDK.
Generate and confirm Smart Wallet shares
Generate MPC Smart Wallet shares and confirm storage so lifecycle state is explicit and auditable in your onboarding flow.
Execute send/sign with gas options
Run asset transfers and signing through one flow, then switch on gas sponsorship where you want a smoother end-user experience.
Protect recovery and eject paths
Persist encrypted backup shares, manage backup statuses, or enable controlled eject windows from your backend proxy.
