Support for EIP712 Arrays in typedData
Currently walletlink (Coinbase Wallet) doesn't seem to support signing messages with Arrays in typedData. At Snapshot we are planning to switch fully to EIP712 and require this for some voting types and for creating proposals.
This proposal can be used to test signing a message with array type: https://bafybeial75q5u2edo3gg5w7z5bkp3id6pgpr4hghebulfowfx74rak2vty.on.fleek.co/#/fabien.eth/proposal/0x1dbca6fa6e9685180dfa2b2bcd10bbb51721c16a1135fdbb40f904747c09bdb5
If you login with Coinbase wallet and try to cast a vote, it will fail with this error:
