Updating Spl Token Metadata with MetaMask and Solana CLI
As a developer working in the Solana ecosystem, you need to keep your Spl token metadata up to date. In this article, we’ll show you how to update your Spl token metadata using the Solana blockchain (SOL) Chaincode-based API and the MetaMask browser extension.
Prerequisites
- Solana CLI: Make sure you have the latest version of Solana CLI installed. You can download it from the official Solana website.
- MetaMask: Install MetaMask on your computer to interact with the Solana blockchain.
- Spl Token Contract: Create a new Spl token contract using Solidity (SOL) and deploy it to the Solana network.
- Chaincode: Configure Chaincode on Solana to update metadata.
Step 1: Update metadata with MetaMask
- Launch MetaMask on your computer.
- Connect your account to the MetaMask browser extension.
- Go to MetaMask settings and select “Chaincode” from the menu.
- Search for “Solana” and create a new chaincode contract, e.g.
metadata-updater.
- Update your Spl token contract metadata using the following command:
solana update-chaincode metadata-updater 0x...YOUR Chaincode ID...
Replace 0x...YOUR Chaincode ID... with your actual chaincode ID.
Step 2: Integrate Solana CLI and Chaincode
- Install the Solana CLI command line tool using npm or yarn:
npm install solana-cli -g
yarn global add solana-cli
- Connect to the Solana network using the
solana CLIcommand:
solana connection
- Build and deploy the chaincode contract to the Solana network using the following commands:
npx solana build metadata-updater --target solana-ops-sdk-v0.43.1
npx solana build-metadata-updater 0x...YOUR Chaincode ID...
Step 3: Update metadata with MetaMask
- Launch MetaMask on your computer.
- Connect your account to the MetaMask browser extension.
- Go to MetaMask settings and select “Chaincode” from the menu.
- Search for “Solana” and create a new chaincode contract, e.g.
metadata-updater.
- Update your Spl token contract metadata using the following command:
solana update-chaincode metadata-updater 0x...YOUR Chaincode ID...
Replace 0x...YOUR Chaincode ID... with your actual chaincode ID.
Troubleshooting
If you encounter issues updating your metadata, check the following:
- Make sure you have properly installed the Solana CLI command line tool.
- Check that your chaincode contract and metadata file are up to date.
- Check for errors in your MetaMask settings or chaincode configuration.
- If you are using a local blockchain network, make sure you are connected to it and have a valid identifier.
Conclusion
Updating your Spl token metadata using the Chaincode-based Solana API is a straightforward process. By following the steps and troubleshooting tips below, you should be able to successfully update your metadata using MetaMask and the Solana CLI. Happy developing!
