Get all assets the wallet holds

This endpoint can help you fetch all the Assets a wallet holds including native tokens, fungible tokens, non fungible tokens & multitokens.

Managing digital assets across various blockchain networks can be a challenging task. However, with TatumSDK, a powerful TypeScript library, developers can effortlessly retrieve wallet balances from multiple blockchains using a unified interface. This guide will demonstrate how to leverage TatumSDK's cross-chain capabilities to obtain wallet balances on Ethereum and Bitcoin, two popular, yet different blockchain networks. By following the steps outlined, you'll be able to streamline the development process and build applications that easily interact with multiple blockchains, saving time and reducing complexity.

How to get a balance on Ethereum network

Use the TatumSDK (@tatumio/tatum) to get a balance of the wallet.

Hint

TatumSDK wraps multiple different calls to the Tatum API together in 1 function, so we don't show here the curl example for using direct HTTP API calls. You can check the API documentation for specific operations, which are internally used inside the library.

// yarn add @tatumio/tatum
import {TatumSDK, Network, Ethereum, ResponseDto, AddressBalance} from '@@tatumio/tatum'

const tatum = await TatumSDK.init<Ethereum>({network: Network.ETHEREUM})

const balance: ResponseDto<AddressBalance[]> = await tatum.address.getBalance({
  addresses: ['0xF64E82131BE01618487Da5142fc9d289cbb60E9d'], // replace with your address
})

console.log(balance.data)
// Install with: npm install @tatumio/tatum
import { TatumSDK, Network } from "@tatumio/tatum";

(async () => {
  try {
    const tatum = await TatumSDK.init({ network: Network.ETHEREUM });
    const balance = await tatum.address.getBalance({
      addresses: ['0xF64E82131BE01618487Da5142fc9d289cbb60E9d'], // replace with your address
    });
    console.log(balance.data);
  } catch (error) {
    console.error("Error fetching wallet balance:", error);
  }
})();

Expected Response

[
    {
        asset: 'ETH',
        address: '0xF64E82131BE01618487Da5142fc9d289cbb60E9d',
        decimals: 18,
        balance: '0.001',
        type: 'native',
    }
]

How to get a balance on the Bitcoin network

In order to get a balance of a Bitcoin address, you can use the same approach and reuse the same code.

// yarn add @tatumcom/js
import {TatumSDK, Network, Bitcoin, ResponseDto, AddressBalance} from '@tatumio/tatum'

const tatum = await TatumSDK.init<Bitcoin>({network: Network.BITCOIN})

const balance: ResponseDto<AddressBalance[]> = await tatum.address.getBalance({
  addresses: ['bc1q7zw9ax8tm4jk2k2674u6lcd9fwjut8kqtvfeg8'], // replace with your address
})

console.log(balance.data)

// Expected outcome
// [{
//     asset: 'BTC',
//     address: 'bc1q7zw9ax8tm4jk2k2674u6lcd9fwjut8kqtvfeg8',
//     decimals: 8,
//     balance: '0.001',
//     type: 'native',
// }]
// Install with: npm install @tatumcom/js
const { TatumSDK, Network } = require("@tatumio/tatum");

(async () => {
  try {
    const tatum = await TatumSDK.init({ network: Network.BITCOIN });
    const balance = await tatum.address.getBalance({
      addresses: ["bc1q7zw9ax8tm4jk2k2674u6lcd9fwjut8kqtvfeg8"], // replace with your address
    });
    console.log(balance.data);
  } catch (error) {
    console.error("Error fetching wallet balance:", error);
  }
})();

// Expected outcome
// [{
//     asset: 'BTC',
//     address: 'bc1q7zw9ax8tm4jk2k2674u6lcd9fwjut8kqtvfeg8',
//     decimals: 8,
//     balance: '0.001',
//     type: 'native',
// }]

You can see, that the same request and response is used for different blockchain networks.
