eth_getProof

Last updated:

`eth_getProof` returns a cryptographic proof that an account — and the storage slots you ask for — held specific values at a specific block. The proof is the list of Merkle-Patricia trie nodes from the state root down to the account, and from each storage root down to the requested slot, as standardized in [EIP-1186](https://eips.ethereum.org/EIPS/eip-1186).

Use it when you need to *verify* on-chain state against a trusted block header without trusting the RPC node itself — for example in light clients, L2 fraud/validity proofs, cross-chain bridges, or any system that checks account balances and storage values against a known state root.

This is a `pro`-tier method. It is heavier than ordinary reads, so it carries a lower rate limit than `eth_getBalance` / `eth_getStorageAt`. Request only the storage keys you actually need to verify — every extra key adds another proof branch to compute and return.

Examples

curl https://<your-endpoint>/ \
  -X POST -H 'Content-Type: application/json' \
  -d '{"jsonrpc":"2.0","id":1,"method":"eth_getProof","params":[]}'
const res = await fetch("https://<your-endpoint>/", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({
  "id": 1,
  "method": "eth_getProof",
  "params": [],
  "jsonrpc": "2.0"
}),
});
const data = await res.json();
import requests
resp = requests.post("https://<your-endpoint>/", json={"id":1,"method":"eth_getProof","params":[],"jsonrpc":"2.0"})
print(resp.json())
