Foundry 101, a hands on introduction
summary
Foundry installs in under a minute and uses forge for Solidity-native tests and cast as a CLI; tests are Solidity contracts with setup fixtures composed by inheritance, reducing hundreds of JS lines to a few Solidity functions. Features shown: mainnet forking, gas snapshot reports to track regressions, an opcode-level debugger that finds a memory overwrite, and cheat codes like vm.prank and vm.sign to simulate callers and signatures. Migration from Hardhat drops JS boilerplate; deployment tooling is prototype work in progress.
