How to Utilize APIs from Chainbase, Alchemy, and Moralis to Determine ERC-20 Token Balances
Summary:
This article offers comprehensive, step-by-step guides on how to utilize APIs from Chainbase, Alchemy, and Moralis to determine ERC-20 token balances associated with a specific wallet address. These techniques are handy when direct wallet access is unattainable, such as for businesses or law enforcement inquiries. Comprehensive instructions for each platform are included, providing users with a variety of approaches to extract token balance information from a blockchain network.
Deriving the balance of ERC-20 tokens in any wallet is as easy as opening it. All token balances linked to that wallet are automatically shown. However, when it falls on a third party, for instance, a business or law enforcement, to determine the ERC-20 token balances of any given address without direct access to the wallet, an alternative route is available. An Application Programming Interface (API) can be employed to scrutinize the balances of such a wallet, making possible an automated process of token balance assessment.
This article will guide you through how to utilize Chainbase, Alchemy, and Moralis APIs to extract information regarding ERC-20 tokens owned by an address.
Chainbase—the platform that serves as a Web3 blockchain interaction structure— provides API services for seamless exploration and utilization of blockchain networks with its APIs focusing on on-chain data extracts. The necessary tools to work with Chainbase include an account on the platform that comes with an API key, an integrated development environment, and a wallet address as input.
To find all ERC-20 tokens connected to an address using Chainbase:
1. Setup a free account, sign in, then launch your new project from the dashboard where you will obtain your API key.
2. Write a script using JavaScript and Axios to make an API call to Chainbase for ERC-20 token balances.
3. Load the token balances using the getAccountTokens API. Print out the data by running “node .js” in the terminal.
To use Alchemy to determine all ERC-20 tokens related to an address:
1. Download and install Node and the Node Package Manager (NPM).
2. Sign up for Alchemy, create a new app specifying Ethereum as the blockchain then note the HTTP URL and API key.
3. Install the required Node.js dependencies in an empty repository.
4. Pass the wallet address as the argument to the getTokenBalances method to receive token balances connected to the address.
To easily comprehend the earlier output which presents token contract addresses and balances in the smallest units, use the getTokenMetadata function for a neatly packaged information about the tokens.
To use Moralis for finding all ERC-20 tokens associated with an address:
1. Download and install Node.js v14+ and NPM, unpacking the binary to the installation folder. Create a Moralis account and copy the API key.
2. Use Moralis’s 'getWalletTokenBalances' endpoint which checks all ERC-20 tokens connected to an address.
3. Run a command in the terminal to trigger the JavaScript script and determine the tokens held.
Each of these methods provides distinct procedures, highlighting various methods of utilising APIs to determine ERC-20 token balances associated with a specific address.
