​
Overview

With CDP API and SDKs, you can retrieve token balances for any address on supported EVM networks and Solana. This allows you to check balances for both native tokens (like ETH, SOL) and ERC-20/SPL tokens across multiple blockchain networks. The token balance APIs support querying balances for:
  • EVM Networks: Ethereum, Base, and Base Sepolia
  • Solana Networks: Solana Mainnet and Solana Devnet
Token balance queries are read-only operations and do not require account ownership. You can check balances for any public address.

​
EVM Token Balances

Use the listTokenBalances method to retrieve token balances for any EVM address. This method returns both native tokens (like ETH) and ERC-20 tokens held by the address.

​
Basic Usage

import { CdpClient } from "@coinbase/cdp-sdk";
import "dotenv/config";

const cdp = new CdpClient();

const result = await cdp.evm.listTokenBalances({
  address: "0x5b76f5B8fc9D700624F78208132f91AD4e61a1f0",
  network: "base-sepolia",
});

console.log(`Found ${result.balances.length} token balances:`);
for (const balance of result.balances) {
  console.log("Token contract address:", balance.token.contractAddress);
  console.log("Balance amount:", balance.amount.amount);
  console.log("Balance decimals:", balance.amount.decimals);
  console.log("---");
}

​
Supported Networks

The EVM token balance API supports the following networks:
  • Mainnet: ethereum, base
  • Testnet: base-sepolia

​
Pagination

For addresses with many token balances, you can use pagination to retrieve results in manageable chunks: 
// Get the first page of token balances
const firstPage = await cdp.evm.listTokenBalances({
  address: "0x5b76f5B8fc9D700624F78208132f91AD4e61a1f0",
  network: "base-sepolia",
  pageSize: 10,
});

console.log("First page results:");
for (const balance of firstPage.balances) {
  console.log("Token contract address:", balance.token.contractAddress);
  console.log("Balance amount:", balance.amount.amount);
  console.log("Balance decimals:", balance.amount.decimals);
  console.log("---");
}

// Get the next page if available
if (firstPage.nextPageToken) {
  const secondPage = await cdp.evm.listTokenBalances({
    address: "0x5b76f5B8fc9D700624F78208132f91AD4e61a1f0",
    network: "base-sepolia",
    pageSize: 10,
    pageToken: firstPage.nextPageToken,
  });

  console.log("\nSecond page results:");
  for (const balance of secondPage.balances) {
    console.log("Token contract address:", balance.token.contractAddress);
    console.log("Balance amount:", balance.amount.amount);
    console.log("Balance decimals:", balance.amount.decimals);
    console.log("---");
  }
}

​
Solana Token Balances

Use the listTokenBalances method to retrieve token balances for any Solana address. This method returns both native SOL and SPL tokens held by the address.

​
Basic Usage

import { CdpClient } from "@coinbase/cdp-sdk";
import "dotenv/config";

const cdp = new CdpClient();

const result = await cdp.solana.listTokenBalances({
  address: "4PkiqJkUvxr9P8C1UsMqGN8NJsUcep9GahDRLfmeu8UK",
  network: "solana-devnet",
});

console.log(`Found ${result.balances.length} token balances:`);
for (const balance of result.balances) {
  console.log("Token mint address:", balance.token.mintAddress);
  console.log("Balance amount:", balance.amount.amount);
  console.log("Balance decimals:", balance.amount.decimals);
  console.log("---");
}

​
Supported Networks

The Solana token balance API supports the following networks:
  • Mainnet: solana
  • Devnet: solana-devnet

​
Pagination

For addresses with many token balances, you can use pagination: 
// Get the first page of token balances
const firstPage = await cdp.solana.listTokenBalances({
  address: "4PkiqJkUvxr9P8C1UsMqGN8NJsUcep9GahDRLfmeu8UK",
  network: "solana-devnet",
  pageSize: 3,
});

console.log("First page:");
for (const balance of firstPage.balances) {
  console.log("Token mint address:", balance.token.mintAddress);
  console.log("Balance amount:", balance.amount.amount);
  console.log("Balance decimals:", balance.amount.decimals);
  console.log("---");
}

// Get the next page if available
if (firstPage.nextPageToken) {
  const secondPage = await cdp.solana.listTokenBalances({
    address: "4PkiqJkUvxr9P8C1UsMqGN8NJsUcep9GahDRLfmeu8UK",
    network: "solana-devnet",
    pageSize: 2,
    pageToken: firstPage.nextPageToken,
  });

  console.log("\nSecond page:");
  for (const balance of secondPage.balances) {
    console.log("Token mint address:", balance.token.mintAddress);
    console.log("Balance amount:", balance.amount.amount);
    console.log("Balance decimals:", balance.amount.decimals);
    console.log("---");
  }
}

​
Working with Your Own Accounts

If you want to check balances for accounts you’ve created with the CDP SDK, you can easily get the address from your account object: 
// Create or get an existing account
const account = await cdp.evm.getOrCreateAccount({ name: "my-account" });

// Check the account's token balances
const balances = await cdp.evm.listTokenBalances({
    address: account.address,
    network: "base-sepolia",
});

​

The token balance response includes detailed information about each token:
