EIP-712 Replay Protection

[xBalbinus]

Description:
FYI - filecoin-project/lotus#12761
When you’re signing a raw message, the EIP-191 Signed Data Standard adds a prefix so that the message can never be a scam transaction. Hugo is requesting adoption of this common Ethereum standard in Filecoin by Lotus, FEVM contexts, L2s, etc. which is why he’s tagged the folks in this Lotus issue.

Fil-b Team: Related is also EIP-712 which is popular in the Eth community, explained well in https://www.cyfrin.io/blog/understanding-ethereum-signature-standards-eip-191-eip-712this article> and adds replay protection and would get us to clear signing on Ledger. It’s also supported by a lot of wallets and Hugo could add support for it to the iso-filecoin JS library.
