eth_getProof on Mantle

Measured 2026-10-04 by our weekly probe, which calls eth_getProof through the same Mantle 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 Mantle: what we measured

• Default Mantle routing keeps state for roughly the last 1,000,000 blocks (about 23.1 days of Mantle history). A proof for a block older than that needs historical state. Add &archive=1 to send the request to archive upstreams (paid plans).

Example request

curl -s https://rpc.swiftnodes.io/rpc/mantle?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/mantle?key=YOUR_API_KEY") });

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