Ethereum: Foundry scripts read deployed contract addresses

Ethereum: Accessing Deployment Information from the Foundry Environment

As an Ethereum developer, you are probably familiar with the Foundry platform, which provides a convenient way to deploy and manage smart contracts. However, one of the main benefits is access to information about your deployed contracts. In this article, we will explore how to read deployment addresses and other relevant information from the Foundry environment.

Prerequisites

Before you begin, make sure you have created a new contract in Foundry using the “create” command-line interface or the Foundry GUI. This will give you a deployment ID that can be used as an address when interacting with your deployed contracts.

For example:

foundry create my-contract --language Solidity --contract-type script

This would create a new contract named “my-contract” on the “mainnet” network using the Solidity language. The deployment ID will be generated automatically.

Accessing Deployment Information from Foundry

You can access deployment information from your Foundry environment in the following ways:

• Foundry CLI

  

  : Use the “foundry” command-line interface to access your contract’s deployment IDs and other relevant information.

foundry get-deploy-id my-contract
foundry get-contract deployment-id 1234567890abcdef

This will return the deployment ID for your “my-contract” contract.

• Foundry Web Interface: Open the Foundry web interface using the following URL: [ (replace with your actual Foundry URL).

In the Foundry interface, go to your contract’s details page and look for the “Deploy ID” field. This will display the deployment ID.

• Foundry API: The Foundry API allows you to access deployment information programmatically.

import requests
api_url = '
headers = {'Authorization': 'Bearer YOUR_API_KEY'}
response = requests.get(api_url, headers=headers)
deploy_id = response.json().get('id')
print(deploy_id)

Replace “YOUR_API_KEY” with your actual Foundry API key.

Reading Deployment Addresses

You can read the contract address from a deployed contract as follows:

const deployId = 'your-deploy-id-here';
const contractAddress = 0x${deployId.slice(2)};
// Use the contract address to interact with your contract
console.log(contractAddress);

Replace “your-deploy-id-here” with the actual deployment ID of your contract.

Conclusion

Using deployment information from the Foundry environment can save you time and effort when managing your smart contracts. The methods described above allow you to retrieve your contract’s deployment ID and other relevant information for use in your development workflow.
