Overview

getTokenAccountsByOwnerV2 is an enhanced version of the standard getTokenAccountsByOwner method, specifically designed for efficiently querying token portfolios and handling wallets with extensive token holdings. This method introduces cursor-based pagination and incremental update capabilities.

New Features in V2:

• Cursor-based pagination: Configure limits from 1 to 10,000 token accounts per request
• Incremental updates: Use changedSinceSlot to fetch only recently modified token accounts
• Portfolio scalability: Handle wallets with thousands of token accounts efficiently
• Backward compatibility: Supports all existing getTokenAccountsByOwner parameters and filters
• Optional withContext: true adds slot and apiVersion under result.context; omit or false and they are not included

Filter Requirement: You must provide either a mint (specific token) or programId (SPL Token or Token-2022 program) in your query. Querying all token types for an owner without a filter is not supported.

Key Benefits

Large Portfolios

Handle wallets with thousands of token accounts without timeouts or memory issues

Real-time Tracking

Monitor portfolio changes in real-time using changedSinceSlot for incremental updates

withContext (optional)

Boolean on the config object (params[2]). Only the shape of result changes, not filters, limits, or pagination. Omitted or false: result.value is the token account array. true: result.context plus result.value as an object (accounts, paginationKey, totalResults). If you handle both, branch on Array.isArray(result.value).

// Omitted or false
{ "jsonrpc": "2.0", "id": "1", "result": { "value": [], "paginationKey": null, "totalResults": null } }

// true
{ "jsonrpc": "2.0", "id": "1", "result": {
  "context": { "slot": 411895550, "apiVersion": "3.1.9" },
  "value": { "accounts": [], "paginationKey": null, "totalResults": null }
}}

Pagination Best Practices

Important Pagination Behavior: End of pagination is only indicated when no token accounts are returned. The API may return fewer accounts than your limit due to filtering - always continue pagination until paginationKey is null.

Basic Portfolio Query

// Get all SPL Token accounts for a wallet
let allTokenAccounts = [];
let paginationKey = null;

do {
  const response = await fetch(`https://mainnet.helius-rpc.com/?api-key=${API_KEY}`, {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify({
      jsonrpc: '2.0',
      id: '1',
      method: 'getTokenAccountsByOwnerV2',
      params: [
        "9WzDXwBbmkg8ZTbNMqUxvQRAyrZzDsGYdLVL9zYtAWWM", // wallet address
        { "programId": "TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA" },
        {
          encoding: 'jsonParsed',
          limit: 1000,
          ...(paginationKey && { paginationKey })
        }
      ]
    })
  });
  
  const data = await response.json();
  allTokenAccounts.push(...data.result.value);
  paginationKey = data.result.paginationKey;
} while (paginationKey);

console.log(`Total token accounts: ${allTokenAccounts.length}`);

Incremental Portfolio Updates

// Get only token accounts modified since a specific slot
const portfolioUpdates = await fetch(`https://mainnet.helius-rpc.com/?api-key=${API_KEY}`, {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({
    jsonrpc: '2.0',
    id: '1',
    method: 'getTokenAccountsByOwnerV2',
    params: [
      walletAddress,
      { "programId": "TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA" },
      {
        encoding: 'jsonParsed',
        limit: 1000,
        changedSinceSlot: lastUpdateSlot // Only get recent changes
      }
    ]
  })
});

Token Program Support

Token-2022 Support: Use TokenzQdBNbLqP5VEhdkAS6EPFLC1PHnBqCXEpPxuEb as the programId to query Token-2022 accounts with extensions like transfer fees, interest-bearing tokens, and more.

// Query Token-2022 accounts (supports token extensions)
const token2022Response = await fetch(`https://mainnet.helius-rpc.com/?api-key=${API_KEY}`, {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({
    jsonrpc: '2.0',
    id: '1',
    method: 'getTokenAccountsByOwnerV2',
    params: [
      walletAddress,
      { "programId": "TokenzQdBNbLqP5VEhdkAS6EPFLC1PHnBqCXEpPxuEb" }, // Token-2022
      { encoding: 'jsonParsed', limit: 1000 }
    ]
  })
});

Migration from getTokenAccountsByOwner

Migration is simple - just add pagination parameters to your existing queries:

{
  "jsonrpc": "2.0",
  "id": "1",
- "method": "getTokenAccountsByOwner",
+ "method": "getTokenAccountsByOwnerV2",
  "params": [
    "9WzDXwBbmkg8ZTbNMqUxvQRAyrZzDsGYdLVL9zYtAWWM",
    { "programId": "TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA" },
    {
      "encoding": "jsonParsed",
+     "limit": 1000
    }
  ]
}
