How to Get an ERC-20 Token Address

Users, decentralized applications (dApps), and smart contracts require ERC-20 token addresses to interact with tokens—whether for transactions, queries, or function calls. But what exactly is a token address, and how do you find one? This guide explores the easiest methods to retrieve any ERC-20 token’s address.

Key Takeaways

• ERC-20 token addresses are unique identifiers for smart contracts governing tokens.
• Use token explorers (e.g., Moralis Money) or block explorers (e.g., Etherscan) to find addresses quickly.
• Developers can leverage Moralis APIs to fetch token addresses programmatically.
• A step-by-step tutorial demonstrates how to get all ERC-20 token addresses in a wallet.

What Is an ERC-20 Token Address?

The ERC-20 standard defines rules for creating fungible tokens on Ethereum. Each token’s smart contract generates a unique public address (a hexadecimal string) that serves as its identifier.

Why It Matters

• Interoperability: Wallets and dApps use this address to recognize and manage tokens.
• Transactions: Sending/receiving tokens requires the token’s contract address.

3 Easy Ways to Get an ERC-20 Token Address

1. Using a Token Explorer (Moralis Money)

Steps:

1. Visit Moralis Money.
2. Search for the token (e.g., "USDC").
3. Copy the address from the "Coin Address" field.

2. Using a Block Explorer (Etherscan)

Steps:

1. Go to Etherscan.
2. Search for the token name.
3. Locate the address under "Contract" or "Other Info".

3. Programmatically via Moralis APIs

For developers, Moralis offers endpoints like:

• getWalletTokenBalances(): Fetch all tokens in a wallet.
• getTopERC20TokensByMarketCap(): Retrieve top tokens by market cap.
• getTopERC20TokensByPriceMovers(): Identify top gainers/losers.

Tutorial: Get All ERC-20 Token Addresses in a Wallet

Prerequisites:

• Node.js installed.
• Moralis API key (free).

Steps:

1. Install Moralis SDK:

   npm install moralis @moralisweb3/common-evm-utils  

2. Write a Script:

   const Moralis = require("moralis").default;  
   const { EvmChain } = require("@moralisweb3/common-evm-utils");  
   
   const runApp = async () => {  
     await Moralis.start({ apiKey: "YOUR_API_KEY" });  
     const address = "0xWalletAddress";  
     const chain = EvmChain.ETHEREUM;  
     const response = await Moralis.EvmApi.token.getWalletTokenBalances({ address, chain });  
     console.log(response.toJSON());  
   };  
   
   runApp();  

3. Run the Code:

   node index.js  

   Output: A list of tokens with their token_address fields.

FAQ

Why do I need an ERC-20 token’s address?

Can I get token addresses across multiple blockchains?

Yes! Moralis Money supports Ethereum, Polygon, Arbitrum, and more.

How do developers use token addresses?

For building wallets, swaps, or tracking token balances via APIs.
