A collection of EVM puzzles. Each puzzle consists on sending a successful transaction to a contract. The bytecode of the contract is provided, and you need to fill the transaction data that won't revert the execution.
Clone this repository and install its dependencies (npm install or yarn), open puzzles/puzzle_1.js, and fill the value of the data variable. Then run the puzzle by doing npx hardhat run puzzles/puzzle_1.js. You'll get a message saying if the puzzle was solved or not. That's it. And if you solve it, continue with the next ones :)
