eth_getProof on Arbitrum Nova

Measured 2026-10-11 by our weekly probe, which calls eth_getProof through the same Arbitrum Nova endpoint customers use.

What eth_getProof does

Returns an EIP-1186 Merkle proof for an account and selected storage slots, which a client can verify against the block's state root without trusting the RPC provider.

eth_getProof on Arbitrum Nova: what we measured

• Default Arbitrum Nova routing keeps state for roughly the last 64 blocks (about 6.9 hours of Arbitrum Nova history). A proof for a block older than that needs historical state. Archive routing did not measure as available on this chain.

Example request

curl -s https://rpc.swiftnodes.io/rpc/arbitrum-nova?key=YOUR_API_KEY \
  -X POST -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"eth_getProof","params":["0x0000000000000000000000000000000000000000",[],"latest"]}'

import { createPublicClient, http } from "viem";

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

// Any JSON-RPC method, typed loosely: eth_getProof on Arbitrum Nova
const result = await client.request({
  method: "eth_getProof",
  params: ["0x0000000000000000000000000000000000000000",[],"latest"],
});
