To build, test, and deploy the example smart contract, we will use Hardhat, an Ethereum development environment. Make sure you have npm installed before executing the following commands.
First clone the repository and enter the directory.
$ git clone https://github.com/404-DAO/Example-Solidity-Sprint.git
$ cd "Example-Solidity-Sprint"
You have your choice of development frameworks for this sprint. The recommended tools are either Hardhat or Foundry.
Foundry is a command-line tool independent of NPM, meaning you must install it individually on your machine. Instructions on how to do so can be found on their website getFoundry.sh
curl -L https://foundry.paradigm.xyz | bash
It contains tools you may find useful during this challenge including
forge - A testing-framework for smart-contracts in Solidity
cast - A suite of command-line tools for common things in solidity
anvil - a chain-forking CLI-tool similar to ganache
We recommend forge and cast due to their fast runtime and excellent documentation. Once foundry is installed, no further configuration should be necesarry. Any code found in either contracts, test, or script will be compiled by using the forge build command.
Foundry has its own scripting and deployment library as well which you can read up on
Install the necessary dependencies
$ npm i
Compile the ExampleSoliditySprint2022 contract
$ npx hardhat compile
Run associated tests
$ npx hardhat test
Deploy to Goerli
$ npx hardhat run scripts/deploy.js --network Goerli
To deploy your contract or transaction you will need to place your private key in a .env file alongside your hardhat.config.js file under the variable GOERLI_PRIVATE_KEY=[key]

Play around with the contract using Etherscan or locally by running tests.
Try to complete f1. If you're testing locally using hardhat, start here.
Note: Each transaction sent to the network incurs gas cost, consider this when completing f1.
