Sign arbitrary data for off-chain transactions and state channels #297

Closed veqtor closed 3 years ago

veqtor commented 3 years ago

In Ethereum, specifically Metamask, there's a lot of usage of the wallet to sign arbitrary transactions for L2 scaling and login functionality. A similar feature, if implemented in a secure way (there would have to be a prefix so that the bytes being signed aren't a valid in an on-chain tx, unless said on-chain tx is part of the dapp functionality, ex in sidechain BLS threshold aggregation) would allow for very interesting applications.

Ideally this functionality should be implemented as a TZIP, but I was thinking, since metamask developed and then submitted an EIP, you guys could do the same, or?

Hey, sorry for the late response.

This feature is supported. TZIP: https://gitlab.com/tzip/tzip/-/blob/master/proposals/tzip-10/tzip-10.md#2-sign-payload Beacon Connect: https://docs.walletbeacon.io/guides/sign-payload Temple Connect: https://github.com/madfish-solutions/templewallet-dapp#sign
