eth_getProof on Katana
Measured 2026-10-11 by our weekly probe, which calls eth_getProof through the same Katana 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 Katana: what we measured
- Default Katana routing keeps state for roughly the last 1,000,000 blocks (about 11.6 days of Katana 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/katana?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/katana?key=YOUR_API_KEY") });
// Any JSON-RPC method, typed loosely: eth_getProof on Katana
const result = await client.request({
method: "eth_getProof",
params: ["0x0000000000000000000000000000000000000000",[],"latest"],

Frequently asked questions
Does Katana support eth_getProof?
Yes. eth_getProof answered correctly on the SwiftNodes Katana endpoint in our weekly method probe (2026-10-11), which sends real requests through the customer path.
Are there limits on eth_getProof on Katana?
Default Katana routing keeps state for roughly the last 1,000,000 blocks (about 11.6 days of Katana history). A proof for a block older than that needs historical state. Add &archive=1 to send the request to archive upstreams (paid plans).
Katana endpoints, live block height and WebSocket status are on the Katana RPC page.
