So, if you’re already familiar with Gnosis, feel free to skip the initial two sections and jump straight into the ”Moralis’ Gnosis API – Easiest Way to Build Gnosis Dapps” part. 

However, if you’re new to Gnosis, join us in the following section as we briefly explore the intricacies of this network! 

What is Gnosis? Gnosis Chain Explained

Martin Köppelman and Stefan George founded Gnosis back in 2015 when the organization – at the time – was building prediction markets. In 2020, Gnosis announced plans to fully decentralize into a DAO (decentralized autonomous organization). Just one year later, in 2021, the GnosisDAO and xDAI communities voted to combine their ecosystems to create Gnosis Chain! 

So, what is Gnosis Chain? 

Gnosis Chain is an Ethereum sidechain secured by a global network of 160,000+ validators worldwide. The network’s diverse set of validators and focus on community-driven governance ensures that Gnosis Chain remains neutral in its operations.

Furthermore, Gnosis Chain utilizes an innovative dual-token model with two central tokens: xDai and GNO. XDai is a stablecoin pegged to the USD, and it’s used for transactions, fees, and payments on Gnosis Chain. GNO, on the other hand, provides security via Gnosis’ consensus-layer Gnosis Beacon Chain. Consequently, GNO is used for staking, protocol protection, and community governance. 

In addition to the Ethereum sidechain, Gnosis hosts an extensive ecosystem of other products. Two prominent examples include CoW and Safe. CoW, short for ”coincidence of wants”, is a permissionless decentralized exchange (DEX) allowing users to trade ERC-20 tokens. Safe is an account abstraction leader on the Ethereum network with the purpose of accelerating the transition to smart contract accounts.

That briefly covers Gnosis and Gnosis Chain. So, let’s now explore some benefits of building on this network!

The Wallet API features many prominent endpoints, and with only single lines of code, you can seamlessly fetch all tokens, NFTs, native tokens, transactions, etc., and check the activity of any wallet on Gnosis Chain. 

To illustrate the accessibility of this tool, here’s an example of how you can get all NFTs owned by a wallet using the getWalletNFTs() endpoint:  

const response = await Moralis.EvmApi.nft.getWalletNFTs({
  "chain": "0x64",
  "address": "0x88ad09518695c6c3712ac10a214be5109a655671"

Thanks to the multi-chain capabilities of the Wallet API, you can use the same tool to create cross-chain compatible dapps that integrate wallet stats, real-time NFT transfer data, decoded transactions, and much more! 

Blockchain API 

Moralis’ Blockchain API lets you seamlessly unlock the power of raw and decoded blockchain data with precision and pace. As such, when working with this industry-leading interface, it has never been easier to analyze smart contracts, set up real-time alerts, and build powerful trading platforms!

Gnosis API Tutorial: How to Get the Token Balances of any Wallet 

In this section, we’ll provide an in-depth tutorial showing you how to get the token balances of any wallet on the Gnosis Chain. And thanks to the accessibility of the Moralis Gnosis API, you can accomplish this in three straightforward steps: 

  1. Get Your Moralis API Key
  2. Write a Script Calling the getWalletTokenBalances() Endpoint
  3. Execute the Code

However, you must deal with a few essential prerequisites before you can get going! 

Prerequisites for Using the Gnosis API

The Gnosis API supports multiple programming languages. However, in this tutorial, we’ll be using JavaScript. As such, make sure you have the following ready before you proceed: 

  • Node.js v14+
  • NPM/Yarn

Step 1: Get Your Moralis API Key 

The first thing you’ll need to call the Gnosis API is a Moralis API key. Consequently, start by clicking on the ”Start for Free” button at the top right to sign up with Moralis: 

Step 1 - Click on the "Start for Free" button to sign up using Moralis Gnosis API

With an account at hand, you can now click on the ”Settings” tab, scroll down to the ”API Keys” section, and copy your key:

Please keep it for now, as you will use it in the next step! 

Step 2: Write a Script Calling the getWalletTokenBalances() Endpoint 

Open your preferred integrated development environment, set up a new project, and run the following command in the root folder to install the Moralis SDK: 

npm install moralis @moralisweb3/common-evm-utils

Next, create a new ”index.js” file and add the following code: 

const Moralis = require("moralis").default;
const { EvmChain } = require("@moralisweb3/common-evm-utils");

const runApp = async () => {
  await Moralis.start({
    apiKey: "YOUR_API_KEY",
    // ...and any other configuration

  const address = "0x88ad09518695c6c3712ac10a214be5109a655671";

  const chain = "0x64";

  const response = await Moralis.EvmApi.token.getWalletTokenBalances({



From here, start by replacing YOUR_API_KEY with the key you fetched in the previous step: 

Showing the code snippet and where to paste the Gnosis API key

Afterward, configure the address constant by assigning it the address of the wallet from which you want to query the token balances. What’s more, make sure that the chain const is set to 0x64

Showing the address and chain parameters and modifications to make to build on Gnosis Chain

We then pass along both address and chain as parameters when calling the getWalletTokenBalances() endpoint:

That’s it for the code; all that remains from here is running the script! 

Step 3: Execute the Code 

For the final step, open a new terminal and run this command in the root folder of the project: 

node index.js

In return, you should get a response containing an array of all tokens held by the wallet in question. And for each token, you’ll also get the current balance. It should look something like this:

    token_address: '0xfd135b71c8dbb1c2bd052edafc9cba77dd2a7d69',
    symbol: '',
    name: '',
    logo: null,
    thumbnail: null,
    decimals: 18,
    balance: '600000000000000000000000000',
    possible_spam: true

Congratulations; you now know how to get all token balances of any wallet on Gnosis Chain! 

You can follow the same steps to call any other endpoint for Gnosis Chain. You simply need to make minor configurations to the parameters and change the endpoint during the second step!
