Deploying a Contract Using the Second Address in Your Metamask Wallet With Hardhat
When developing smart contracts, it is essential to keep track of multiple addresses and their associated funds. One Common Scenario Involves Having Multiple Wallets, Each Storing Different Accounts or Assets. A contract created with hardhat.
Understanding Hardhat Config
Before diving into deploying contracts, crucial to understand the configuration file used by hardhat for development and production environment. For Local Development, you can use the following Configuration:
`js
module.exports = {
// Your Network Provider (e.g., Infua, EthersGorP)
Network: {
Provider: ‘
Network_id: 1,
},
// Your Wallet Provider (Metamask)
Walletprovider: {
privatekey: ‘
mnemonic: ‘
Gasprice: 20 * Math.Pow (10, 18),
},
// Your Project’s EntryPoint
Entries: [
{from: ‘0xyouraccountadddress’, to: ‘0xcontraddaddress’, args: [‘arg1’, ‘arg2’]},
],
};
`
In the example above:
Network: the provider and network details.
Walletprovider: Your Metamask Wallet Configuration, Including Private Key, Mnemonic, and Gas Price.
Entries: an array of contract deployment configurations.
Deploying Contracts Using Hardhat
To deploy a contract This file will specify the private key and other metadata.
Create a new file named .env inside your project Root:
`bash
Metamask_private_key = your_metascan_private_key
`
Alternatively, you can use hardhat’s built-in configuration feature to define an environment file with a single entry for each wallet.
`js
module.exports = {
// Your Network Provider (e.g., Infua, EthersGorP)
Network: ‘Development’,
// Metamask Wallets
Enviles: {
‘Metamask1’: {
Privatekey: ‘
mnemonic: ‘
Gasprice: 20 * Math.pow (10, 18),
},
‘Metamask2’: {
Privatekey: ‘
mnemonic: ‘
Gasprice: 20 * Math.Pow (10, 18),
},
},
};
`
Now, create a new file named hardhat.config.js with the following configuration:
`js
Const {Ethers} = Require (‘Ethers’);
consta (‘./ Enviles’);
module.exports = {
// Your Project’s EntryPoint
Entries: [
{from: ‘metamask1’, to: ‘0xcontraddress_1’, args: [‘arg1’, ‘arg2’]},
{from: ‘metamask2’, to: ‘0xcontraddress_2’, args: [‘arg3’, ‘arg4’]},
],
};
`
Deploying Contracts
With the Enviles configuration in place, you can now use hardhat to deploy contracts. In your main.js file or any other entry point:
`JavaScript
Const {Ethers} = Require (‘Ethers’);
const {Enviles} = require (‘./ hardhat.config’);
Async Function Main () {
// Import the contract abi and bytecode
Const Contractti = Await Import (‘./ Path/to/contract/abi.json’);
Const contractbytecode = Await import (‘./ path/to/bytecode.json’ contract;
// Get the Accounts from the Environment Files
Const {Metamask1, Metamask2} = Enviles;
// Deploy the Contract Using Hardhat’s Deploy Function`
Const Deployer = New Ethers.providers.jsonrpcprovider (
‘
{
Gasprice: 20 * Math.pow (10, 18),
}
);
Const accounts = Await Deployer.
