eth_getBalance on Abstract

Everything below was measured on 2026-10-13 by calling eth_getBalance on Abstract through the same endpoint customers use, and is re-measured weekly.

What eth_getBalance does

Returns an account's balance of the chain's native token in wei (the smallest unit, 10^-18), at a given block. It works for contracts as well as wallets; ERC-20 balances need eth_call to the token's balanceOf instead.

Example request

curl -s https://rpc.swiftnodes.io/rpc/abstract?key=YOUR_API_KEY \
  -X POST -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"eth_getBalance","params":["0x000000000000000000000000000000000000dEaD","latest"]}'

import { createPublicClient, formatEther, http } from "viem";

const client = createPublicClient({
  transport: http("https://rpc.swiftnodes.io/rpc/abstract?key=YOUR_API_KEY"),
});

const wei = await client.getBalance({ address: "0x000000000000000000000000000000000000dEaD" });
console.log(formatEther(wei), "ETH");

// At a past block (older than the default window: add &archive=1 to the URL)
const then = await client.getBalance({ address: "0x000000000000000000000000000000000000dEaD", blockNumber: 87545212n });

// Many balances in one request: Multicall3 is deployed on Abstract
const balances = await client.multicall({
  contracts: addresses.map((a) => ({ address: "0xcA11bde05977b3631167028862bE2a173976CA11", abi: [{ name: "getEthBalance", type: "function", stateMutability: "view", inputs: [{ type: "address" }], outputs: [{ type: "uint256" }] }], functionName: "getEthBalance", args: [a] })),
});
