cast wallet sign-auth

NAME

cast-wallet-sign-auth - Sign an EIP-7702 authorization.

SYNOPSIS

cast wallet sign-auth address

DESCRIPTION

Sign an EIP-7702 authorization for an address.

Note that sign-auth uses the current nonce as it is not aware of whether you are going to broadcast the authorization from the same or a different sender.

If you are sending the transaction from the same address you will need to either pass the next nonce using the --nonce flag or alternatively use cast send <to> --auth <address> to sign and send directly.
