This repository contains the code sample for measuring gas usages of different usages of ABI encoding used in the article, "Deep Dive into ABI Encoding & Decoding: Techniques, Gas Efficiency, and Key Security Considerations".
TODO: Insert article link here
contracts: Comparison of many different usages of ABI encodingtest: Tests for contracts.hardhart.config.js: Hardhat configuration, including compiler optimization options.
yarn compile: Compile the contracts.yarn test: Run the tests and produce a gas usage report.
