Here is a step-by-step guide to extracting a list of tokens (not NFTs) created by a Solana user using the getParsedTokenAccountsByOwner
method:
Prerequisites
- You have a Solana account with the necessary permissions to access token metadata.
- You have installed Solana CLI and verified your wallet address.
Method: getParsedTokenAccountsByOwner
The getParsedTokenAccountsByOwner
method allows you to retrieve a list of parsed token accounts for a given owner. This method is specific to the Solana Transaction Analysis API and is used to extract data that has not been previously indexed by the Solana blockchain.
Here are the steps to get user-generated tokens:
- Install the required library
: You will need to install the
solana-token-metadata
package using npm or yarn:
`whammy
npm install solana token metadata
Create a script that connects to your Solana cluster and initializes the token metadata index:javascript
const { connect } = require('@solana/web3.js');
const TokenMetadata = require('solana-token-metadata');
// Connect to the Solana network (devnet or testnet)
connect();
// Initialize the token metadata index
const application = new TokenMetadata();
application.init().then(() => {
console.log('Token metadata index initialized!');
}).catch((error) => {
console.error(error);
});
- Get Owner ID: Get the Solana account ID of the user you want to get tokens for. You can use the getAccount
method to get the account object:
javascript
const ownerAccount = await getAccount();
console.log('Owner Account:', ownerAccount);
getParsedTokenAccountsByOwner
Call: Use the
getParsedTokenAccountsByOwnerfunction to get a list of parsed token accounts for the specified owner:
javascript
- ${token.tokenId}const parsedTokens = await app.getParsedTokenAccountsByOwner(accountOwner.publicKey.toString());
console.log('Parsed tokens:');
parsedTokens.forEach((token) => {
console.log(
);
});
Code Example
Here is an example code snippet that demonstrates how to get user-generated tokens using the getParsedTokenAccountsByOwnermethod:
javascript
const { connect, getAccount } = require('@solana/web3.js');
const TokenMetadata = require('solana-token-metadata');
// Connect to the Solana network (devnet or testnet)
connect();
// Initialize the token metadata index
application.init().then(() => {
console.log('Token metadata index initialized!');
}).catch((error) => {
console.error(error);
});
async function fetchTokens() {
const accountOwner = await getAccount();
const parsedTokens = await app.getParsedTokenAccountsByOwner(ownerAccount.publicKey.toString());
console.log(Parsed tokens: ${parsedTokens.length});
// Processing parsed token data
parsedTokens.forEach((token) => {
console.log(– ${token.tokenId});
});
}
getTokens();
`
This code connects to the Solana network, initializes the token metadata index, and callsgetParsedTokenAccountsByOwnerto get a list of tokens created by a given owner. The received tokens are then processed and written to the console.
Note that this example uses thegetAccountmethod to retrieve the account object and the
getParsedTokenAccountsByOwner` function to retrieve the parsed token accounts. You will need to modify these functions to suit your specific use case.
