sign_typed_dataPython,latest
Go to PyPISign the EIP-712 typed structured data from a specified developer-controlled wallet. This endpoint only supports Ethereum and EVM-compatible blockchains. Please note that not all Dapps currently support Smart Contract Accounts (SCA); the difference between Ethereum's EOA and SCA can be found in the account types guide. You can also check the list of Ethereum Dapps that support SCA: https://eip1271.io/.
