đĒ ERC20sLearn how to fetch ERC20 tokens in common from multiple users.
Airstack provides easy-to-use APIs for enriching dapps and integrating on-chain and off-chain data from Ethereum, Base, Degen Chain, and other Airstack-supported chains .
In this guide, you will learn how to use Airstack to fetch ERC20 Tokens In Common .
Pre-requisites
Basic knowledge of GraphQL
Get Started
JavaScript/TypeScript/Python
If you are using JavaScript/TypeScript or Python, Install the Airstack SDK:
npm yarn pnpm pip
React
Copy npm install @airstack/airstack-react
Node
Copy npm install @airstack/node
React
Copy yarn add @airstack/airstack-react
Node
Copy yarn add @airstack/node
React
Copy pnpm install @airstack/airstack-react
Node
Copy pnpm install @airstack/node
Then, add the following snippets to your code:
React Node Python
Copy 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 (loading) {
return < p >Loading...</ p >;
}
if (error) {
return < p >Error: { error .message}</ p >;
}
};
Copy import { init , fetchQuery } from "@airstack/airstack-react" ;
init ( "YOUR_AIRSTACK_API_KEY" );
const query = "YOUR_QUERY" ; // Replace with GraphQL Query
const { data , error } = fetchQuery (query);
console .log ( "data:" , data);
console .log ( "error:" , error);
Copy 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.
ERC20 Tokens In Common
You can fetch common ERC20 tokens of multiple user(s) provided the user's 0x address, Farcaster name or ID, ENS domains, or Lens profile:

Query Response
Copy query MyQuery {
TokenBalances(
input: {
filter : { owner : { _eq : "betashop.eth" }, tokenType : { _eq : ERC20 } }
blockchain : base
}
) {
TokenBalance {
token {
tokenBalances(
input: {
filter : {
owner : { _eq : "tokenstaker.eth" }
tokenType : { _eq : ERC20 }
}
}
) {
id
token {
address
symbol
name
}
}
}
}
}
}
Copy {
"data" : {
"TokenBalances" : {
"TokenBalance" : [
{
"token" : {
"tokenBalances" : [
{
"id" : "af2c9253761bbc7a547caa471e99a9641b1f5029d01a2374bd3c872017f61d33" ,
"token" : {
"address" : "0x4ed4e862860bed51a9570b96d89af5e1b0efefed" ,
"symbol" : "DEGEN" ,
"name" : "Degen"
}
}
]
}
} ,
{
"token" : {
"tokenBalances" : [] // owned by betashop.eth, but not tokenstaker.eth
}
}
]
}
}
}
