Solana: how to update metadata of spl-tokens using cli

Updating Spl Token Metadata with MetaMask and Solana CLI

As a developer working on the Solana ecosystem, it is essential to keep the Spl token metadata up to date. In this article, we will explore how to update 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 for metadata updates.

Step 1: Update Metadata Using MetaMask

• Launch MetaMask on your computer.

• Log in to your account with the MetaMask browser extension.

• Go to MetaMask settings and select “Chaincode” from the menu.

• Search for “Solana” and create a new chaincode contract, such as metadata-updater.

• Update the metadata for the Spl token contract using the following command:

Solana update-chaincode metadata-updater 0x...YOUR Chaincode ID...

Replace 0x...Your Chaincode ID... with the actual ID of your chaincode.

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 thesolana CLIcommand:

solana connect

• Compile and deploy the chaincode contract to the Solana network using the following commands:

npx solana compile metadata-updater --target solana-ops-sdk-v0.43.1
npx solana build-metadata-updater 0x... Your chaincode ID...

• Search for “Solana” and create a new chaincode contract, such asmetadata-updater.

Solana update-chaincode metadata-updater 0x...YOUR Chaincode ID...

Replace 0x…Your Chaincode ID…` with the actual ID of your chaincode.

Troubleshooting

If you are having trouble updating metadata, please check the following:

• Make sure you have installed the Solana CLI command line tool correctly.

• Verify that the 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 the correct ID.

Conclusion

Updating the metadata of your Spl token with the Solana API based on Chaincode is a simple process. By following these steps and troubleshooting tips, you should be able to successfully update the metadata using MetaMask and the Solana CLI. Happy development!
