This repository is an appendix to the official discussion taking place on the official forum. Please start by reading it at this address: https://community.starknet.io/t/snip-off-chain-signatures-a-la-eip712 This repository might not be up-to-date, which is why, in doubt, always refer to the official discussion and feel free to open an Issue/PR.
The purpose of this repository is NOT to establish a set of standard interfaces but rather to present different cases and how to produce a hash that is compatible with StarknetJS. Although I tried to stay as close as possible to the terms used in EIP-712 and in the StarknetJS documentation
Note that each file can be taken as a standalone, which is why there some code is duplicated. The most simple case can be found here
