  EVM Assembly Composer (Development)
  https://github.com/yarrumretep/evm-asm
  This open-source project is a JavaScript framework that allows for easy composition of Ethereum Virtual Machine Assembly code.
  Snapshotable | Easily Snapshot the On-chain State (Development)
  https://github.com/yarrumretep/snapshotable
  This open-source project facilitates the creation of snapshots of states that require users to cheaply track historical balances for implementations of voting, dividend, and/or other timing based functionality in smart contracts.
  Solidity Contract Clone Framework (Development)
  https://github.com/yarrumretep/clone-factory
  This open source project encapsulates a technique that we developed for deploying multiple super-efficient identical contracts on an Ethereum blockchain. It has been adopted by several projects and has allowed these projects to save on the deployment and operation costs of their systems.
