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>;
  }
};

Airstack provides an AI solution for you to build GraphQL queries to fulfill your use case easily. You can find the AI prompt of each query in the demo's caption or title for yourself to try.

Get ERC20 Token Total Supply

You can fetch an ERC20 token's total supply by using the totalSupply field from Tokens API by providing ERC20 token contract address as an input:

Try Code

Show me total supply of @Wrapped Ether

Demo

query TotalSupply {
  Tokens(
    input: {
      filter: { address: { _eq: "0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2" } }
      blockchain: ethereum
    }
  ) {
    Token {
      totalSupply
      decimals
    }
  }
}

Get ERC20 Token Name & Symbol

You can fetch an ERC20 token's name and symbol by using the name and symbol fields from Tokens API by providing ERC20 token contract address as an input:

Try Demo

Show me the name and symbol of @Wrapped Ether

Code

query MyQuery {
  Tokens(
    input: {
      filter: { address: { _eq: "0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2" } }
      blockchain: ethereum
    }
  ) {
    Token {
      name
      symbol
    }
  }
}

Get ERC20 Token Logo Images

You can fetch all ERC20 token logo images by using the Tokens API by providing ERC20 token contract address as an input:

Try Demo

Show me the the logo image of @Wrapped Ether

Code

query MyQuery {
  Tokens(
    input: {
      filter: { address: { _eq: "0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2" } }
      blockchain: ethereum
    }
  ) {
    Token {
      projectDetails {
        imageUrl
      }
    }
  }
}
