Description

Finds the address that deployed the provided contract and the block number it was deployed in.

📘

Note

This method performs a binary search across all blocks since genesis and can take a long time to complete. This method is a convenience method that will eventually be replaced by a single call to an Alchemy endpoint with this information cached.

Parameters

Response

DeployResult response object parameters

Example Request and Response

Prerequisite: You will need to install the Alchemy SDK before making requests with it.

The commands for installing it using npm or yarn are given below:

npm install alchemy-sdk

yarn add alchemy-sdk

Request

Here is an example of how to make a findContractDeployer 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 () => {
    //Assign the contract address to a variable
    let address = "0xbc4ca0eda7647a8ab7c2061c2e118a18a936f13d"

    //The response fetches the contract deployer of the above address
    let response = await alchemy.core.findContractDeployer(address)

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

main();

Response

And here is an example of what a successful response to this request might look like:

{
  deployerAddress: '0xaba7161a7fb69c88e16ed9f455ce62b791ee4d03',
  blockNumber: 12287507
}

Use Cases

Here are some common use cases for findContractDeployer method:

• Contract verification: When a new contract is deployed on a blockchain, it is important to verify the identity of the deployer to ensure that the contract was deployed by a trusted source. By using the findContractDeployer method, developers can easily verify the deployer of a contract and ensure that the contract is legitimate.

• Security auditing: Security auditors can use the findContractDeployer method to identify potential security vulnerabilities in a smart contract by analyzing the behavior of the deployer. If the deployer is identified as a potential threat, additional security measures can be implemented to prevent unauthorized access to the contract.

• Contract management: Smart contracts are often used to automate business processes and manage digital assets. By using the findContractDeployer method, contract managers can identify who has deployed a particular contract and ensure that it is being used in accordance with the terms and conditions agreed upon by all parties.
