FAQ

EIP-1271 is a proposal that aims to standardize the process of verifying signatures when an account is a smart contract, e.g., a multi-sig.

You can use this DApp tool on desktop and mobile to validate signatures from a wallet account that implements WalletConnect and EIP-1271.
Also, you can use it to verify whether or not such a wallet account signed a specific message.

For now, only Ethereum Mainnet is supported. This tool has been designed to work specifically for Safe Multi-sigs even though it should also work with others.

Click on Connect Wallet in the navigation bar of this app, copy the link and paste it into the Safe WalletConnect app.
