How to resolve an ENS domain

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: Resolve ENS domain

In order to resolve the ENS domain to an ETH address, Moralis provides you a resolveENSDomain endpoint to do so.

Here you'll need one parameter: domain.

Once you've obtained the domain, 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 domain = "vitalik.eth";

  const response = await Moralis.EvmApi.resolve.resolveENSDomain({
    domain,
  });

  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 domain = "vitalik.eth";

  const response = await Moralis.EvmApi.resolve.resolveENSDomain({
    domain,
  });

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

runApp();

index.py (Python)

from moralis import evm_api

api_key = "YOUR_API_KEY"

params = {
  "domain": "vitalik.eth",
}

result = evm_api.resolve.resolve_ens_domain(
    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": "0x26fcbd3afebbe28d0a8684f790c48368d21665b5"
}

Congratulations 🥳 You just resolved the address to an ENS domain with just a few lines of code using the Moralis Resolve API!
