How to get ERC20 metadata by symbols

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 symbols

In order to get ERC20 metadata by symbols, Moralis provides you with an getTokenMetadataBySymbol endpoint.

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

Once you have obtained the symbols 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 symbols = ["UNI", "AAVE", "LINK"];

  const chain = EvmChain.ETHEREUM;

  const response = await Moralis.EvmApi.token.getTokenMetadataBySymbol({
    symbols,
    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 symbols = ["UNI", "AAVE", "LINK"];

  const chain = EvmChain.ETHEREUM;

  const response = await Moralis.EvmApi.token.getTokenMetadataBySymbol({
    symbols,
    chain,
  });

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

runApp();

index.py (Python)

from moralis import evm_api

api_key = "YOUR_API_KEY"
params = {
    "symbols": ['UNI', 'AAVE', 'LINK'],
    "chain": "eth"
}

result = evm_api.token.get_token_metadata_by_symbol(
    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:
