Monad API method that returns the value from a storage position at a given address. This method allows you to read the raw storage of smart contracts, which is useful for debugging and analyzing contract state.

When called against a block older than the latest ~128 blocks, this method is treated as an archive request (2 RUs instead of 1 RU). See request units.

Parameters

• data — the 20-byte address of the storage.
• quantity — the position in the storage as a hexadecimal string.
• quantity|tag — the block number as a hexadecimal string, or one of the following block tags:
  • latest — the most recent block in the canonical chain

Response

• result — the value at this storage position, encoded as a 32-byte hexadecimal string.

eth_getStorageAt code examples

ethers.js

const { ethers } = require("ethers");

const provider = new ethers.JsonRpcProvider("CHAINSTACK_NODE_URL");

async function getStorageAt() {
  const contractAddress = "0xAc586b65F3cd0627D2D05AdB8EF551C9d2D76E12";
  const position = "0x0"; // Storage slot 0
  const value = await provider.getStorage(contractAddress, position);
  console.log(`Storage value at position 0: ${value}`);
}

getStorageAt();

Use case

A practical use case for eth_getStorageAt is reading private or internal state variables from smart contracts that are not exposed through public getter functions, or verifying that a contract’s storage layout matches expected values during audits.
