This repo contains the files I generated and my notes taken during the Cyfrin DAO and Governance Lesson as part of the Advanced Foundry course.

Foundry

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

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.

LESSON NOTES

My notes taken during this course can be found in the Notes.md file of this repository.

ENVIRONMENT VARIABLES

FROM TERMINAL, WE WANT FORGE TO REFER TO OUR .ENV FILE. TO DO THIS:

$ source .env

Documentation

Usage

Build

Test

$ forge test

Format

$ forge fmt

Gas Snapshots

$ forge snapshot

Anvil

$ anvil

Deploy

$ forge script script/Counter.s.sol:CounterScript --rpc-url <your_rpc_url> --private-key <your_private_key>

Cast

$ cast <subcommand>

Cast Function Signature

• Will return hexadecimal value
• Allows to check that we are doing what we expect to be doing- e.g check hex data in metamask against the hex value of function name to verify correct function is being called

$ cast sig "functionName()"

Cast Using CallData Decode

• This is used to achieve the same goal of 'cast sig', however, this is used for functions that have parameters which makes the hex string much larger
• This would return what each of the parameters are for the function

$ cast --calldata-decode "functionName()" HexString(e.g.2a4d5b etc etc)
