Tutorial: Using EIP-712

[qbzzt]

Tutorial title

Using EIP-712

Tutorial description

EIP-712 enables us to have the user's wallet ask for a signature and then verify that signature on-chain. This enables, for example, organizations to sponsor the gas for transactions by their users while still keeping those users in control.

However, EIP-712 is not trivial to use. You need to specify the correct codes both on the contract side and the client side.
