EIP712 Signing Demo

This is a demonstration of EIP712 signing support via MetaMask's eth_signTypedData_v3 API call. It includes copy-and-paste Solidity code that performs EIP712 hashing and ecrecovery on-chain.

Try it here.

Please use MetaMask version 4.14.0 and above as earlier versions do not necessarily support eth_signTypedData_v3.
