base-camp

Implementation of solutions to the exercises of the Base Camp.

This codebase uses Foundry, a blazing fast, portable and modular toolkit for Ethereum application development written in Rust.

Deployment, Verification and Submission

Deployment

Pre-requisites

Set up wallet

Set up your preferred wallet (eg. Coinbase Wallet), enable the Base Goerli Testnet and fund your Ethereum address with test ETH (eg. using the Bware Labs Base Faucet).

Enable auto-compile

In the Solidity compiler settings check the Auto compile checkbox.

Deployment Steps

One simple but manual approach to deploying contracts to a network consists of the following steps:

1. Navigate to the official Remix IDE website: https://remix.ethereum.org/
2. Create a new workspace using the Basic template and name it as desired (eg. base-camp)
3. Add a new file under the contracts directory with the name of the contract you're looking to deploy (eg. BasicMath.sol)
4. Select Injected Provider and make sure that Base Görli network is selected
5. Select the contract you're looking to deploy in the CONTRACT dropdown
6. Hit the deploy button (after configuring any deployment options that may be needed for your contract)

Verification Steps

After deploying a contract,

1. Copy the address of the deployed contract (eg. hit the Copy button under the Deployed Contracts section on the Deploy and run transactions panel in the Remix IDE)
2. Navigate to Base Scan: https://goerli.basescan.org/address/<contract address here>
3. Click on the Contract tab
4. Click on Verify & Publish and follow the steps

Submission for testnet NFT

1. Navigate to the exercise page (eg. Control Structures Exercise)
2. Hit the Connect button to connect your desired wallet. This does not have to be the same wallet or used to deploy the contract, it can be any of your wallets. Make sure to select the Base Görli network in your wallet.
3. Paste the address of the contract you're looking to submit in the Contract address input field
4. Hit the Submit button and confirm in your wallet

Foundry Commands

Foundry consists of:

• Forge: Ethereum testing framework (like Truffle, Hardhat and DappTools).
• Cast: Swiss army knife for interacting with EVM smart contracts, sending transactions and getting chain data.
• Anvil: Local Ethereum node, akin to Ganache, Hardhat Network.
• Chisel: Fast, utilitarian, and verbose solidity REPL.
