How to get all ERC20 transfers by contract

Suggest Edits

If you want to automatically get all the transfers of an ERC20 token, try Chainbase API getTokenTransfers. You can easily retrieve all the transfers for any ERC20 token with its contract address by using Chainbase API.

Overview - Tools you need to work with Chainbase

  1. A free account at Chainbase with an API key.
  2. An IDE. Our examples are shown in JavaScript, you can use VS Code as your IDE for example.
  3. A contract address of an ERC20 token as your input.

Step 1: Set up a free account at Chainbase

To better leverage the ability that Chainbase provides, you can register here for a free account and access to different APIs and data cloud.

After logging into Chainbase, visit the dashboard to get an overview. Create a new project in the console and get an API key.

Step 2: Write script using Chainbase API

  1. Using fetch in JavaScript.
network_id = '1'; // See https://docs.chainbase.com/reference/supported-chains to get the id of different chains.
contract_addr = '0x7d1afa7b718fb893db30a3abc0cfc608aacfebb0'; // Take Matic Token's contract address as an example.

fetch(`https://api.chainbase.online/v1/token/transfers?chain_id=${network_id}&contract_address=${contract_addr}&page=1&limit=5`, {
    method: 'GET',
    headers: {
        'x-api-key': CHAINBASE_API_KEY, // Replace the field with your API key.
        'accept': 'application/json'
    }
}).then(response => response.json())
    .then(data => console.log(data.data))
    .catch(error => console.error(error));
  1. Using axios in JavaScript. You need to install axios using npm install axios --save in the terminal first.
network_id = '1'; // See https://docs.chainbase.com/reference/supported-chains to get the id of different chains.
contract_addr = '0x7d1afa7b718fb893db30a3abc0cfc608aacfebb0'; // Take Matic Token's contract address as an example.

const axios = require('axios');
const options = {
    url: `https://api.chainbase.online/v1/token/transfers?chain_id=${network_id}&contract_address=${contract_addr}&page=1&limit=5`,
    method: 'GET',
    headers: {
        'x-api-key': CHAINBASE_API_KEY, // Replace the field with your API key.
        'accept': 'application/json'
    }
};
axios(options)
    .then(response => console.log(response.data.data))
    .catch(error => console.log(error));

Step 3: Print metadata of an ERC20 token

Chainbase API getTokenTransfers takes the chain id and token contract address as parameters, and returns all the transfers of that ERC20 token. If you want to know transfers related to one specific address, input the address information in the address field. You can also know the total transfer times through the count field in the returned data.

To get data printed, run command node <filename>.js in the terminal. In this case, the data returned looks as follows.
