Returns the value of the provided position at the provided address, at the provided block in Bytes32 format.

Parameters

ParameterTypeDescription
addressOrNamestringThe address or ENS name of the account to get the code for.
positionintegerThe position of the storage slot to get.
blockTagstringThe optional block number or hash to get the code for. Defaults to 'latest' if unspecified.

blockTag parameters

  • pending - A sample next block built by the client on top of latest and containing the set of transactions usually taken from local mempool. Intuitively, you can think of these as blocks that have not been mined yet.
  • latest - The most recent block in the canonical chain observed by the client, this block may be re-orged out of the canonical chain even under healthy/normal conditions.
  • safe - The most recent crypto-economically secure block, cannot be re-orged outside of manual intervention driven by community coordination. Intuitively, this block is “unlikely” to be re-orged. Only available on Ethereum Goerli.
  • finalized - The most recent crypto-economically secure block, that has been accepted by >2/3 of validators. Cannot be re-orged outside of manual intervention driven by community coordination. Intuitively, this block is very unlikely to be re-orged. Only available on Ethereum Goerli.
  • earliest - The lowest numbered block the client has available. Intuitively, you can think of this as the first block created.

Response

PropertyTypeDescription
Promise<string>stringReturns the value at this storage position.

Example Request and Response

Request

Here is an example of how to make a getStorageAt request using the Alchemy SDK:

// Imports the Alchemy SDK
const { Alchemy, Network } = require("alchemy-sdk");

// Configures the Alchemy SDK
const config = {
    apiKey: "alchemy-replit", // Replace with your API key
    network: Network.ETH_MAINNET, // Replace with your network
};

// Creates an Alchemy object instance with the config to use for making requests
const alchemy = new Alchemy(config);

const main = async () => {
    //Initialize variables for the parameters
    let address = "registrar.firefly.eth"
    let position =  0
    
    //Call the method to get storage
    let response = await alchemy.core.getStorageAt(address, position)

    //Logging the response to the console
    console.log(response)
};

main();
