Description

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

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

Request

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

1
// Imports the Alchemy SDK
2
const { Alchemy, Network } = require("alchemy-sdk");
3
4
// Configures the Alchemy SDK
5
const config = {
6
    apiKey: "alchemy-replit", // Replace with your API key
7
    network: Network.ETH_MAINNET, // Replace with your network
8
};
9
10
// Creates an Alchemy object instance with the config to use for making requests
11
const alchemy = new Alchemy(config);
12
13
const main = async () => {
14
    //Assign the contract address to a variable
15
    let address = "0xbc4ca0eda7647a8ab7c2061c2e118a18a936f13d"
16
17
    //The response fetches the contract deployer of the above address
18
    let response = await alchemy.core.findContractDeployer(address)
19
20
    //Logging the response to the console
21
    console.log(response)
22
};
23
24
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.
