🔑0x Address

Learn how to use Airstack to universally resolve and reverse resolve 0x addresses to Solana addresses, Farcaster, and ENS Domains (including offchain Namestone & cb.id).

In this guide, you will learn how to use Airstack to:

Pre-requisites

An Airstack account
Basic knowledge of GraphQL

Get Started

JavaScript/TypeScript/Python

If you are using JavaScript/TypeScript or Python, Install the Airstack SDK:

React

npm install @airstack/airstack-react

Node

npm install @airstack/node

React

yarn add @airstack/airstack-react

Node

yarn add @airstack/node

React

pnpm install @airstack/airstack-react

Node

pnpm install @airstack/node

pip install airstack

Then, add the following snippets to your code:

import { init, useQuery } from "@airstack/airstack-react";

init("YOUR_AIRSTACK_API_KEY");

const query = `YOUR_QUERY`; // Replace with GraphQL Query

const Component = () => {
  const { data, loading, error } = useQuery(query);

  if (data) {
    return <p>Data: {JSON.stringify(data)}</p>;
  }

  if (loading) {
    return <p>Loading...</p>;
  }

  if (error) {
    return <p>Error: {error.message}</p>;
  }
};

import { init, fetchQuery } from "@airstack/node";

init("YOUR_AIRSTACK_API_KEY");

const query = `YOUR_QUERY`; // Replace with GraphQL Query

const { data, error } = await fetchQuery(query);

console.log("data:", data);
console.log("error:", error);

import asyncio
from airstack.execute_query import AirstackClient

api_client = AirstackClient(api_key="YOUR_AIRSTACK_API_KEY")

query = """YOUR_QUERY""" # Replace with GraphQL Query

async def main():
    execute_query_client = api_client.create_execute_query_object(
        query=query)

    query_response = await execute_query_client.execute_query()
    print(query_response.data)

asyncio.run(main())

Other Programming Languages

To access the Airstack APIs in other languages, you can use https://api.airstack.xyz/gql as your GraphQL endpoint.

Get All Solana Addresses Connected To 0x Address

You can get all the solana addresses connected to a given 0x addresss by using the Wallet API:

Try Demo

Code

query MyQuery {
  Wallet(
    input: {identity: "0xe0235804378c31948e81441f656d826ee5998bc6", blockchain: ethereum}
  ) {
    farcaster: socials(input: {filter: {dappName: {_eq: farcaster}}}) {
      connectedAddresses { # Fetch all SOL connected addresses from Farcaster (if any)
        address
        chainId
        blockchain
        timestamp
      }
    }
    domains {
      multiChainAddresses { # Fetch all SOL address registered with ENS (if any)
        address
        symbol
      }
    }
  }
}

{
  "data": {
    "Wallet": {
      "farcaster": [
        {
          "connectedAddresses": [ // No SOL address connected in FC
            {
              "address": "0xe0235804378c31948e81441f656d826ee5998bc6",
              "chainId": "1",
              "blockchain": "ethereum",
              "timestamp": "2023-07-04T18:54:04Z"
            }
          ]
        }
      ],
      "domains": [
        {
          "multiChainAddresses": [
            {
              // This is the SOL address registered by user in ENS
              "address": "GJQUFnCu7ZJHxtxeaeskjnqyx8QFAN1PsiGuShDMPsqV",
              "symbol": "SOL"
            },
            {
              "address": "0xe0235804378c31948E81441f656D826eE5998Bc6",
              "symbol": "ETH"
            }
          ]
        }
      ]
    }
  }
}

Get All 0x Addresses Connected To Solana Address

You can get all the 0x addresses connected to a given solana addresss by using the Wallet API:

Try Demo

Code

query MyQuery {
  Wallet(
    input: {
      identity: "GJQUFnCu7ZJHxtxeaeskjnqyx8QFAN1PsiGuShDMPsqV"
      blockchain: ethereum
    }
  ) {
    addresses
  }
}

{
  "data": {
    "Wallet": {
      "addresses": ["0xe0235804378c31948e81441f656d826ee5998bc6"]
    }
  }
}

Get All Farcaster and ENS Domains Resolved From An Array of 0x addresses

You can resolve an array of 0x addresses to their Farcaster account and ENS Domains (including offchain domains, e.g. Namestone & cb.id) using the Socials and Domains API:

Try Demo

Code

query MyQuery {
  # Get All Farcaster accounts
  Socials(
    input: {
      filter: {
        identity: {
          _in: ["0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045"]
        }
      },
      blockchain: ethereum
    }
  ) {
    Social {
      userAssociatedAddresses
      dappName
      profileName
    }
  }
  # Get All ENS domains, including offchain Namestone & cb.id
  Domains(
    input: {
      filter: {
        resolvedAddress: {
          _in: ["0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045"]
        }
      },
      blockchain: ethereum
    }
  ) {
    Domain {
      resolvedAddress
      name
      isPrimary
    }
  }
}

{
  "data": {
    "Socials": {
      "Social": [
        {
          "userAssociatedAddresses": [

          ],
          "dappName": "farcaster",
          "profileName": "vitalik.eth" // Farcaster fname
        }
      ]
    },
