Metadata Update Commands

To process any of the below commands, you must first ensure that you have update authority over the NFT(s) that you are trying to udpate. To setup your key, follow the steps below:

1. Rename .env.example to .env.
2. Add your private key to the .env file, e.g.:

PRIV_KEY=kNykCXNxgePDjFbDWjPNvXQRa8U12Ywc19dFVaQ7tebUj3m7H4sF4KKdJwM7yxxb3rqxchdjezX9Szh8bLcQAjb

3. Run node solsnapper.js convert NOTE: This command converts a private key from B58 to Uint8Array which is what solana commandline uses by default. It will spit out a key.json file.
