Every user who signs in to a Startale-integrated application gets an ERC-4337 smart account. The SDK exposes this account through a standard EIP-1193 provider, so wagmi, viem, and ethers all work without modification.

​
How accounts are created

When a user signs in with Google, LINE, Apple, or MetaMask, an embedded wallet is provisioned for them. The smart account is deterministically derived from that embedded wallet, then deployed on first use.

​
Signature compatibility

Signatures returned by the SDK are ERC-1271 compatible. To verify them off-chain, use viem’s verifyMessage. It resolves smart-account signatures automatically by calling isValidSignature on the deployed account.

​
Counterfactual signatures

Before the smart account is deployed, signatures are wrapped per ERC-6492. Verifiers that support 6492, including viem, handle both deployed and undeployed accounts transparently.

Smart-account internals are implemented in scs-aa-sdk, Startale’s open-source account-abstraction primitive. You do not need to install it directly. @startale/app-sdk includes everything you need.
