HyVM
HyVM is an EVM Hypervisor written in Huff that enables execution of arbitrary EVM bytecode.

What is HyVM?
HyVM is an Ethereum Virtual Machine (EVM) Hypervisor written in Huff, serving as the execution core of mass.money. It allows the execution of arbitrary EVM bytecode by functioning as a library called with delegateCall. Developers can call the HyVM library with delegateCall to process smart contract bytecode, enabling custom and complex logic with chained calls. Written in Huff and dependent on Foundry's Forge, HyVM re-implements each opcode to fit its own memory layout and logic, effectively running an EVM on top of the EVM.
