Writing, testing and debugging contracts using Buidler
summary
Live demo shows how to set up a Solidity project with Buidler, use ethers and Waffle to deploy and test a minimal token with an initial supply of 1,000,000, and write mocha/chai tests that call ethers.getSigners, deploy via ContractFactory, check balances and run transfers. Debugging uses Buidler EVM plus console.log in Solidity to print state and VM stack traces, and Waffle assertions like expect().to.be.revertedWith to verify require reverts; deploy scripts target Infura/Ropsten when replacing VM keys.
