# signTypedData

Signs [EIP-712](https://eips.ethereum.org/EIPS/eip-712) typed data via [ERC-7739 `TypedDataSign` format](https://eips.ethereum.org/EIPS/eip-7739).

This Action is suitable to sign messages for contracts (e.g. ERC-4337 Smart Accounts) that implement (or conform to) [ERC-7739](https://eips.ethereum.org/EIPS/eip-7739) (e.g. Solady's [ERC1271.sol](https://github.com/Vectorized/solady/blob/main/src/accounts/ERC1271.sol)).

With the calculated signature, you can use [`verifyTypedData`](/docs/actions/public/verifyTypedData) to verify the signature

## Account and/or Verifier Hoisting

If you do not wish to pass an `account` and/or `verifier` to every `signTypedData`, you can also hoist the Account and/or Verifier on the Wallet Client (see `config.ts`).
