It is recommended to install Yarn through the npm package manager, which comes bundled with Node.js when you install it on your system. It is recommended to use a Node.js version >= 16.0.0.

Once you have npm installed, you can run the following both to install and upgrade Yarn:

npm install --global yarn

After having installed Yarn, simply run:

yarn install

Example Goerli:

yarn deploy:goerli

The deployment script deploy.ts includes the tenderly Hardhat Runtime Environment (HRE) extension with the verify method. Please consider uncommenting and configuring the Tenderly project, username, forkNetwork, privateVerification, and deploymentsDir attributes in the hardhat.config.ts file before deploying or remove this call. Also, for this plugin to function you need to create a config.yaml file at $HOME/.tenderly/config.yaml or %HOMEPATH%\.tenderly\config.yaml and add an access_key field to it. For further information, see here.

yarn xdeploy

This template uses the xdeploy Hardhat plugin. Check out the documentation for more information on the specifics of the deployments.

In the .env file place the private key of your wallet in the PRIVATE_KEY section. This allows secure access to your wallet to use with both testnet and mainnet funds during Hardhat deployments. For more information on how this works, please read the documentation of the npm package dotenv.

Truffle developed the Truffle Dashboard to provide an easy way to use your existing MetaMask wallet for your deployments and for other transactions that you need to send from a command line context. Because the Truffle Dashboard connects directly to MetaMask it is also possible to use it in combination with hardware wallets like Ledger or Trezor.

First, it is recommended that you install Truffle globally by running:

npm install -g truffle

To start a Truffle Dashboard, you need to run the following command in a separate terminal window:

truffle dashboard

By default, the command above starts a Truffle Dashboard at http://localhost:24012 and opens the Dashboard in a new tab in your default browser. The Dashboard then prompts you to connect your wallet and confirm that you're connected to the right network. You should double check your connected network at this point, since switching to a different network during a deployment can have unintended consequences.

Eventually, in order to deploy with the Truffle Dashboard, you can simply run:

yarn deploy:dashboard

You can start an instance of the Hardhat network that forks the mainnet. This means that it will simulate having the same state as the mainnet, but it will work as a local development network. That way you can interact with deployed protocols and test complex interactions locally. To use this feature, you need to connect to an archive node.

This template is currently configured via the hardhat.config.ts as follows:

forking: {
    url: process.env.ETH_MAINNET_URL || "",
    // The Hardhat network will by default fork from the latest mainnet block
    // To pin the block number, specify it below
    // You will need access to a node with archival data for this to work!
    // blockNumber: 14743877,
    // If you want to do some forking, set `enabled` to true
    enabled: false,
}

Change the contract address to your contract after the deployment has been successful. This works for both testnet and mainnet. You will need to get an API key from etherscan, snowtrace etc.

Example:

npx hardhat verify --network fantomMain --constructor-args arguments.js <YOUR_CONTRACT_ADDRESS>

This template repository also includes the Foundry toolkit.

If you need help getting started with Foundry, I recommend reading the 📖 Foundry Book.

make update

or

forge update

make build

or

forge build

To run only TypeScript tests:

yarn test:hh

To run only Solidity tests:

yarn test:forge

or

make test

To additionally display the gas report, you can run:

make test-gasreport

Inside the scripts/ folder are a few preconfigured scripts that can be used to deploy and verify contracts via Foundry. These scripts are required to be executable meaning they must be made executable by running:

make scripts
