How to get ERC20 metadata by contract

Step 1: Setup Moralis

Read the article Setting Up Moralis: Getting Started and make sure to finish all the steps. Only after that you can go ahead to complete this guide.

Step 2: Get ERC20 metadata by contract

In order to get all ERC20 metadata by contract, Moralis provides you with an getTokenMetadata endpoint.

Here you'll need two parameters: addresses and chain.

Once you have obtained the addresses and chain, you can copy the following code:

index.js (JavaScript)

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 = ["0x1f9840a85d5af5bf1d1762f925bdaddc4201f984"];

  const chain = EvmChain.ETHEREUM;

  const response = await Moralis.EvmApi.token.getTokenMetadata({
    addresses,
    chain,
  });

  console.log(response.toJSON());
};

runApp();

index.ts (TypeScript)

import Moralis from "moralis";
import { EvmChain } from "@moralisweb3/common-evm-utils";

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

  const address = ["0x1f9840a85d5af5bf1d1762f925bdaddc4201f984"];

  const chain = EvmChain.ETHEREUM;

  const response = await Moralis.EvmApi.token.getTokenMetadata({
    addresses,
    chain,
  });

  console.log(response.toJSON());
};

runApp();

index.py (Python)

from moralis import evm_api

api_key = "YOUR_API_KEY"
params = {
    "addresses": ["0x1f9840a85d5af5bf1d1762f925bdaddc4201f984"],
    "chain": "eth"
}

result = evm_api.token.get_token_metadata(
    api_key=api_key,
    params=params,
)

print(result)

Step 3: Run the script

To run the script, enter the following command:

Shell (JavaScript)

node index.js

Shell (TypeScript)

ts-node index.ts

Shell (Python)

python index.py

In your terminal, you should see the following JSON response:

[
  {
    "address": "0x1f9840a85d5af5bf1d1762f925bdaddc4201f984",
    "name": "Uniswap",
    "symbol": "UNI",
    "decimals": "18",
    "logo": "https://cdn.moralis.io/eth/0x1f9840a85d5af5bf1d1762f925bdaddc4201f984.webp",
    "logo_hash": "064ee9557deba73c1a31014a60f4c081284636b785373d4ccdd1b3440df11f43",
    "thumbnail": "https://cdn.moralis.io/eth/0x1f9840a85d5af5bf1d1762f925bdaddc4201f984_thumb.webp",
    "block_number": null,
    "validated": null,
    "created_at": "2022-01-20T10:39:55.818Z"
  }
]

Congratulations 🥳 You just got ERC20 metadata by contract with just a few lines of code using the Moralis Token API!
