This package serves to generate a Types object compatible with EIP-712 ( https://w3c-ccg.github.io/ethereum-eip712-signature-2021-spec/ )
Import getEthTypesFromInputDoc into your project and pass in the message that you intend to sign using EIP-712, including the proof object. This will return an object that can be used as the types object passed into eth_signTypedDatav4
Simply run yarn to initialize project, then yarn test to test.
