eth_getProof - SEI

Example code for the eth_getProof JSON-RPC method. Complete guide on how to use eth_getProof JSON-RPC in GetBlock Web3 documentation.

Returns the IAVL proof (note: not a MPT proof) of the given keys for an account on Sei. This is useful for verifying account state.

Parameters

Parameter	Type	Description
address	string	The address of the account
storageKeys	array	Array of storage keys to prove
block	string	Block number in hex, or 'latest', 'earliest', 'pending', 'safe', 'finalized'

import { ethers } from 'ethers';

const provider = new ethers.JsonRpcProvider('https://shared.eu-central-1.getblock.io/<ACCESS-TOKEN>/');

// Using ethers provider methods
const result = await provider.send('eth_getProof', ["0x742d35Cc6634C0532925a3b844Bc9e7595f5bE21", ["0x0"], "latest"]);
console.log(result);
