Can anyone point me to a smart contract with an ERC-20 token interface and with an ERC-1271 custom signature logic?

I want to bridge a token that does not use secp256k1. I am going to play around on a local chain on my laptop with Hardhat first. ERC-1271 is built for this purpose, and so I'll use that.

Just to start with, I'll forget the bridging logic. I want to mint an ERC-20 token with ERC-1271 signature verification. Can anyone point me to a solidity smart contract that can do this?
