NFTEE - EIP712 Minting Example

This SUAPP example showcases how you can write a SUAPP to generate a 712 signature on SUAVE that can then ben sent to a contract on Eth L1 which allows you to mint an NFT.

Usage

Solidity

Like all examples in this repo:

forge build

Go Script

Before running you need to fill in some values:

• PRIV_KEY: Valid ECDSA Private Key with L1 Eth. (Hexadecimal format)
• ETH_RPC_URL: Ethereum L1 testnet RPC URL.
• ETH_CHAIN_ID: Chain Id of the L1 you're testing on.

To run the script, execute the following command in your terminal:

go run main.go

Notes

• The DOMAIN_SEPARATOR and MINT_TYPEHASH are currently hard coded, you will need to make this dynamic for you prod application. Also Accepting PRs!
• Ensure that the Ethereum Goerli testnet account associated with the provided private key has sufficient ETH to cover transaction fees.
• The script currently targets the Goerli testnet. For mainnet deployment, update the ETH_RPC_URL and ETH_CHAIN_ID appropriately, and ensure that the account has sufficient mainnet ETH.

712

The source code for creating the 712 Signature is based off Testing EIP-712 Signatures.
