🏁 Prerequisites

1. You have a Deploy NFT Contractson the Palm network written in Solidity, compiled and deployed.
2. You have the contract source code and the metadata file which contains the compilation settings.

Using the Sourcify Verifier

1. Go to the online verifier
2. Drag and drop the folder containing your source files and metadata, or add them separately. See below to help you find the correct files generated by Using Sourcify or Using Sourcify
3. Input the contract address you want to verify. If a contract at that address is verified in any of the chains it will be shown above.
4. Select the chain the contract is deployed to.
5. Click Verify.

With Hardhat

If you are using Hardhat to deploy your smart contracts you can verify in two ways:

Online
