Using web3.js

import { Connection, PublicKey } from '@solana/web3.js';

const connection = new Connection('https://rpc.orbitflare.com');

// Get token accounts by delegate
const delegate = new PublicKey('4vJ9JU1bJJE96FWSJKvHsmmFADCg4gpZQff4P3bkLZj');
const programId = new PublicKey('TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA');
const accounts = await connection.getTokenAccountsByDelegate(delegate, { programId });
console.log('Token accounts:', accounts);

// Get token accounts by delegate with analysis
async function getTokenAccountsByDelegateWithAnalysis(
  delegate: PublicKey,
  config: { programId: PublicKey; commitment?: string }
) {
  const accounts = await connection.getTokenAccountsByDelegate(delegate, config);
  
  return {
    accounts,
    analysis: {
      totalAccounts: accounts.value.length,
      totalBalance: accounts.value.reduce((sum, acc) => {
        const amount = BigInt(acc.account.data.parsed.info.tokenAmount.amount);
        return sum + amount;
      }, BigInt(0)),
      byMint: accounts.value.reduce((acc, account) => {
        const mint = account.account.data.parsed.info.mint;
        const amount = BigInt(account.account.data.parsed.info.tokenAmount.amount);
        acc[mint] = (acc[mint] || BigInt(0)) + amount;
        return acc;
      }, {} as Record<string, bigint>),
      metadata: {
        timestamp: Date.now(),
        commitment: config.commitment
      }
    }
  };
}

​

Notes

1. Returns all token accounts where the given public key is a delegate
2. The delegate has the authority to transfer tokens from these accounts
3. The response is immediate as it reads from the current state
4. The accounts can change with token transfers and other operations
5. The delegate must be a valid public key

​

Best Practices

1. Use appropriate commitment level based on your needs
2. Cache results when appropriate to reduce RPC load
3. Monitor for changes in delegated accounts
4. Consider using websocket subscription for real-time updates
5. Handle network errors and retry when appropriate

Use Cases

1. Delegate Account Analysis

   interface DelegateAccountAnalysis {
     delegate: string;
     accounts: Array<{
       pubkey: string;
       mint: string;
       balance: string;
       owner: string;
     }>;
     metrics: {
       totalAccounts: number;
       totalBalance: string;
       byMint: Record<string, string>;
       byOwner: Record<string, number>;
     };
     metadata: {
       timestamp: number;
       commitment?: string;
     };
   }
   
   class DelegateAccountAnalyzer {
     async analyzeDelegateAccounts(
       delegate: PublicKey,
       config: { programId: PublicKey; commitment?: string }
     ): Promise<DelegateAccountAnalysis> {
       const accounts = await connection.getTokenAccountsByDelegate(delegate, config);
       
       const byMint: Record<string, bigint> = {};
       const byOwner: Record<string, number> = {};
       let totalBalance = BigInt(0);
       
       accounts.value.forEach(account => {
         const mint = account.account.data.parsed.info.mint;
         const owner = account.account.data.parsed.info.owner;
         const amount = BigInt(account.account.data.parsed.info.tokenAmount.amount);
         
         byMint[mint] = (byMint[mint] || BigInt(0)) + amount;
         byOwner[owner] = (byOwner[owner] || 0) + 1;
         totalBalance += amount;
       });
       
       return {
         delegate: delegate.toBase58(),
         accounts: accounts.value.map(account => ({
           pubkey: account.pubkey,
           mint: account.account.data.parsed.info.mint,
           balance: account.account.data.parsed.info.tokenAmount.amount,
           owner: account.account.data.parsed.info.owner
         })),
         metrics: {
           totalAccounts: accounts.value.length,
           totalBalance: totalBalance.toString(),
           byMint: Object.fromEntries(
             Object.entries(byMint).map(([mint, amount]) => [mint, amount.toString()])
           ),
           byOwner
         },
         metadata: {
           timestamp: Date.now(),
           commitment: config.commitment
         }
       };

       const currentAccounts = new Map(
         accounts.value.map(account => [
           account.pubkey,
           account.account.data.parsed.info.tokenAmount.amount
         ])
       );
       
       const changes: Array<{
         type: 'added' | 'removed' | 'modified';

       }> = [];
       
       // Check for removed or modified accounts
       this.previousAccounts.forEach((balance, account) => {
