Solana: How to update spl-tokens metadata using cli

Updating Spl Token Metadata Using MetaMask and Solana CLI

As a developer working in the Solana ecosystem, it is important to regularly update your Spl token metadata. In this article, we will explore how to update Spl token metadata using the Solana (SOL) blockchain chaincode API and the MetaMask browser extension.

Prerequisites

• Solana CLI: Make sure you have the latest version of Solana CLI installed. It can be downloaded from the Solana official website.

• MetaMask: Install MetaMask on your computer to interact with the Solana blockchain.

• Spl Proxy Contract: Create a new Spl proxy contract using Solidity (SOL) and deploy it to the Solana network.

• Chaincode: Configure the chaincode on the Solana website for metadata updates.

1. Step 2: Update Metadata Using 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, such as “metadata-updater”.

• Update the metadata of the Spl proxy contract using the following command:

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

Replace “0x…YOUR Chaincode ID…” with your actual chaincode ID.

2. Step 1: 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

solana connect

• 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 the metadata using 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, such as “metadata-updater”.

• Update the metadata of the Spl proxy contract 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 are having trouble updating the metadata, please check the following.

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

• Please check that the chaincode contract and metadata file are up to date.

• Check for errors in MetaMask 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 a spl token using Solana’s chaincode-based API 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!
