eth_call on Ethereum
Everything below was measured on 2026-10-13 by calling eth_call on Ethereum through the same endpoint customers use, and is re-measured weekly.
What eth_call does
Executes a call against a block's state without creating a transaction, and returns the output bytes. Every contract read (balanceOf, quotes, view functions) is an eth_call. It costs nothing on-chain but still runs the EVM on the node.
eth_call on Ethereum: what we measured
| Multicall3 at 0xcA11…CA11 | deployed (3,808 bytes) |
|---|---|
| block.number seen inside a call | 26,183,537 |
| eth_blockNumber at the same time | 26,183,536 |
| State override (third parameter) | supported |
| Call with gas 0xffffffffffffffff | accepted (capped by the node) |
| Block given by hash (EIP-1898) | accepted |
What this means on Ethereum
State overrides work: you can replace an account's code, balance or storage for one call. That lets you simulate a transaction from an address with no funds, or test a contract change before deploying it.
Multicall3 is deployed at the standard address, so viem's client.multicall and ethers' multicall helpers batch many reads into one eth_call here without configuration.
Example request
curl -s https://rpc.swiftnodes.io/rpc/eth?key=YOUR_API_KEY \
-X POST -H "Content-Type: application/json" \
-d '{"jsonrpc":"2.0","id":1,"method":"eth_call","params":[{"to":"0xcA11bde05977b3631167028862bE2a173976CA11","data":"0x42cbb15c"},"latest"]}'import { createPublicClient, erc20Abi, http } from "viem";
const client = createPublicClient({
transport: http("https://rpc.swiftnodes.io/rpc/eth?key=YOUR_API_KEY"),
});
const balance = await client.readContract({
address: token, abi: erc20Abi, functionName: "balanceOf", args: [owner],
});
// Many reads in one eth_call (Multicall3 is deployed on Ethereum)
const [name, symbol, supply] = await client.multicall({
contracts: ["name", "symbol", "totalSupply"].map((functionName) => ({ address: token, abi: erc20Abi, functionName })),
allowFailure: false,
});
// Simulate with a state override: pretend the sender holds 10 ETH
await client.call({ account: sender, to, data, stateOverride: [{ address: sender, balance: 10n * 10n ** 18n }] });Other methods on Ethereum

Frequently asked questions
Does Ethereum support eth_call?
Yes. eth_call answered on the SwiftNodes Ethereum endpoint when our weekly probe called it through the customer path (2026-10-13).
Is Multicall3 deployed on Ethereum?
Yes, at 0xcA11bde05977b3631167028862bE2a173976CA11 (3,808 bytes of code, checked 2026-10-13).
Does eth_call support state overrides on Ethereum?
Yes. The third parameter accepts code, balance and storage overrides.
Ethereum endpoints, live block height and WebSocket status are on the Ethereum RPC page.
One key covers every chain we serve, and SwiftNodes has a free tier.
