Advanced Sample Hardhat Project

This project demonstrates an advanced Hardhat use case, integrating other tools commonly used alongside Hardhat in the ecosystem.

The project comes with a sample contract, a test for that contract, a sample script that deploys that contract, and an example of a task implementation, which simply lists the available accounts. It also comes with a variety of other tools, preconfigured to work with the project code.

Try running some of the following tasks:

npx hardhat accounts npx hardhat compile npx hardhat clean npx hardhat test npx hardhat node npx hardhat help REPORT_GAS=true npx hardhat test npx hardhat coverage npx hardhat run scripts/deploy.js node scripts/deploy.js npx eslint '**/*.js' npx eslint '**/*.js' --fix npx prettier '**/*.{json,sol,md}' --check npx prettier '**/*.{json,sol,md}' --write npx solhint 'contracts/**/*.sol' npx solhint 'contracts/**/*.sol' --fix

Etherscan verification

To try out Etherscan verification, you first need to deploy a contract to an Ethereum network that’s supported by Etherscan, such as Ropsten.

In this project, copy the .env.template file to a file named .env, and then edit it to fill in the details. Enter your Etherscan API key, your Ropsten node URL (eg from Alchemy), and the private key of the account which will send the deployment transaction. With a valid .env file in place, first deploy your contract:

hardhat run --network ropsten scripts/deploy.js

Then, copy the deployment address and paste it in to replace DEPLOYED_CONTRACT_ADDRESS in this command:

npx hardhat verify --network ropsten DEPLOYED_CONTRACT_ADDRESS "Hello, Hardhat!"

高级示例Hardhat Project

该项目演示了一个高级的安全帽用例,集成了生态系统中与安全帽一起常用的其他工具

该项目附带了一个示例合同、该合同的测试、部署该合同的示例脚本,以及一个简单列出可用帐户的任务实现示例。它还附带了各种其他工具,这些工具预先配置为与项目代码一起使用

尝试运行以下一些任务:

npx hardhat accounts npx hardhat compile npx hardhat clean npx hardhat test npx hardhat node npx hardhat help REPORT_GAS=true npx hardhat test npx hardhat coverage npx hardhat run scripts/deploy.js node scripts/deploy.js npx eslint '**/*.js' npx eslint '**/*.js' --fix npx prettier '**/*.{json,sol,md}' --check npx prettier '**/*.{json,sol,md}' --write npx solhint 'contracts/**/*.sol' npx solhint 'contracts/**/*.sol' --fix

以太扫描验证

要尝试Etherscan验证,首先需要将合同部署到Etherscan支持的以太坊eth网络,如Ropsten

在此项目中,将.env.template文件复制到名为.env的文件中,然后对其进行编辑以填充详细信息。输入Etherscan API密钥、Ropsten节点URL(例如来自Alchemy)以及将发送部署事务的帐户的私钥。有了有效的.env文件后,首先部署合同:

hardhat run --network ropsten scripts/deploy.js

然后,复制部署地址并将其粘贴到命令中以替换部署的合同地址:

npx hardhat verify --network ropsten DEPLOYED_CONTRACT_ADDRESS "Hello, Hardhat!"
