Abstract: Get ERC-20 Token Balances with RPC Nodes

It doesn’t matter should you’re constructing a Web3 pockets, portfolio tracker, tax instrument, or different comparable platforms – chances are high, you want entry to the ERC-20 token balances of your customers. Nevertheless, querying ERC-20 token balances from RPC nodes has historically been a bothersome and time-consuming endeavor. Doing so requires many requests and necessitates stitching collectively plenty of information your self. Luckily, there’s now a extra streamlined different: Moralis’ Prolonged RPC Strategies.

Our Prolonged RPC Strategies make it doable to question decoded and enriched information seamlessly utilizing RPC-style requests. With this function, you solely want a single name to get ERC-20 token balances, transaction histories, token costs, and extra utilizing RPC nodes.

To focus on the accessibility of our Prolonged RPC Strategies, right here’s the eth_getTokenBalances endpoint in motion:

import fetch from ‘node-fetch’;

const choices = {
technique: ‘POST’,
headers: {
settle for: ‘utility/json’,
‘content-type’: ‘utility/json’
},
physique: JSON.stringify({
“jsonrpc”: “2.0”,
“id”: 1,
“technique”: “eth_getTokenBalances”,
“params”: [
{
“address”: “0xcB1C1FdE09f811B294172696404e88E658659905”,
}
]
})
};

fetch(‘YOUR_NODE_URL’, choices)
.then(response => response.json())
.then(response => console.log(response))
.catch(err => console.error(err));

In return for calling the script above, you’ll get the ERC-20 token balances of the required handle, enriched with token logos, spam indicators, and far more. Right here’s a pattern response:

{
//…
consequence: [
{
token_address: ‘0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2’,

},
//…
]
}
