ThegetCompressedAccountsByOwner RPC method returns all compressed accounts owned by a specific address, with support for filtering, pagination, and data slicing.

You can test this method via the OpenAPI example or custom examples below.

Common Use Cases

• Portfolio Discovery: Find all compressed accounts for a wallet
• Token Account Enumeration: Discover user’s compressed token holdings
• Account Migration: Identify accounts to migrate from regular to compressed
• Balance Aggregation: Calculate total holdings across all accounts

Parameters

1. owner (PublicKey, required): Base58-encoded public key of the account owner to query compressed accounts for.
2. options (object, optional): Configuration object for filtering and pagination:
   • filters (array, optional): Array of filter objects to narrow results by specific criteria
   • dataSlice (object, optional): Slice of account data to return with offset and length fields
   • cursor (string, optional): Cursor for pagination from previous response to fetch next page
   • limit (BN, optional): Maximum number of accounts to return (use bn() helper)

Note: All options parameters are optional. Without filters, returns all compressed accounts for the owner.

Response

The response contains a paginated list of compressed accounts:

• items (array): Array of compressed account objects with merkle context
  • hash (string): Unique hash identifying the account for merkle proof generation
  • address (string, optional): Account address if available
  • lamports (number): Account balance in lamports
  • owner (string): Public key of the account owner
  • data (object): Account data information including discriminator and data hash
  • tree (string): Public key of the merkle tree storing this account
  • leafIndex (number): Position of account in the merkle tree
  • seq (number): Sequence number for account ordering
  • slotCreated (number): Slot when account was created
• cursor (string | null): Pagination cursor for next batch, null if no more results

Developer Tips

• Pagination Strategy: Use cursor-based pagination for owners with many accounts to avoid timeouts and ensure consistent results
• Data Slicing Optimization: Implement data slicing when you only need account metadata to reduce response size and improve performance
• Empty Response Handling: Handle cases gracefully where new addresses have no compressed accounts - this is normal behavior
• Caching Considerations: Cache results appropriately as compressed account states can change with each transaction
• Batch Size: Start with smaller batch sizes (50-100) and adjust based on response times and data needs

Troubleshooting

No accounts found

Owner has no compressed accounts

This is normal for new addresses or those that haven’t used compression:

const accounts = await rpc.getCompressedAccountsByOwner(owner);

if (accounts.items.length === 0) {
    console.log("No compressed accounts found for this owner");
    console.log("Create compressed accounts first using createAccountWithLamports or token operations");
}

Request timeout with large responses

Too many accounts returned at once

Use pagination and data slicing to reduce response size:

const accounts = await rpc.getCompressedAccountsByOwner(owner, {
    limit: bn(50),        // Smaller batch size
    dataSlice: {          // Reduce data per account
        offset: 0,
        length: 10
    }
});

Examples

The below examples work - just make sure you installed the dependencies.

Dependencies & Setup

npm install @lightprotocol/stateless.js @solana/web3.js

For Rust examples: Requires light-client, solana-sdk, anyhow, and tokio crates. See Rust example comments for setup details.

Example: Get All Compressed Accounts

TypeScript

import { createRpc, Rpc } from '@lightprotocol/stateless.js';
import { PublicKey } from '@solana/web3.js';

const rpc: Rpc = createRpc(
  'https://devnet.helius-rpc.com/?api-key=YOUR_API_KEY',
  'https://devnet.helius-rpc.com/?api-key=YOUR_API_KEY'
);

async function getAllCompressedAccounts() {
    const owner = new PublicKey('OWNER_ADDRESS_HERE');
    const result = await rpc.getCompressedAccountsByOwner(owner);

    console.log(\`Found ${result.items.length} compressed accounts\`);

    result.items.forEach((account, index) => {
        console.log(\`Account ${index + 1}:\`);
        console.log(\`  Hash: ${account.hash.toString()}\`);
        console.log(\`  Lamports: ${account.lamports.toString()}\`);
        console.log(\`  Owner: ${account.owner.toBase58()}\`);
    });

    return result;
}

getAllCompressedAccounts();

Rust Client: light-client v0.14.0 is available on crates.io. Use LightClient for the current stable API.

// Current API: light-client 0.14.0
use light_client::rpc::LightClient;

use anyhow::Result;

#[tokio::main]
async fn main() -> Result<()> {
    let client = LightClient::new("https://devnet.helius-rpc.com/?api-key=YOUR_API_KEY".to_string()).await?;

    // Query compressed accounts by owner
    let owner = Pubkey::from_str("OWNER_PUBKEY_HERE")?;

    match client.get_compressed_accounts_by_owner(&owner, None).await? {
        response => {
            println!("Found {} compressed accounts", response.value.items.len());

            for (index, account) in response.value.items.iter().enumerate() {
                println!("Account {}:", index + 1);
                println!("  Hash: {}", account.hash);
                println!("  Lamports: {}", account.lamports);
                println!("  Owner: {}", account.owner);

                println!("  Leaf Index: {}", account.leaf_index);
            }
        }
    }

    Ok(())

import { createRpc, bn, Rpc } from '@lightprotocol/stateless.js';
import { PublicKey } from '@solana/web3.js';

const rpc: Rpc = createRpc(
  'https://devnet.helius-rpc.com/?api-key=YOUR_API_KEY',

async function getAllAccountsPaginated(owner: PublicKey) {
    let allAccounts = [];
    let cursor = undefined;
    let totalBalance = bn(0);
    const batchSize = 100;

    do {
        const batch = await rpc.getCompressedAccountsByOwner(owner, {
            cursor,
            limit: bn(batchSize)
        });

        allAccounts.push(...batch.items);
        cursor = batch.cursor;

        // Calculate running balance
        batch.items.forEach(account => {
            totalBalance = totalBalance.add(account.lamports);
        });

        console.log(\`Fetched ${batch.items.length} accounts, total: ${allAccounts.length}\`);

        // Rate limiting
        await new Promise(resolve => setTimeout(resolve, 100));

    } while (cursor);

    console.log(\`Total compressed accounts: ${allAccounts.length}\`);
    console.log(\`Total balance: ${totalBalance.toString()} lamports\`);
    return { accounts: allAccounts, totalBalance };

// Usage
const owner = new PublicKey('OWNER_ADDRESS_HERE');

    accounts.items.forEach((account, index) => {
