Featured Hacks


🚧 OP Stack Hacks are explicitly things that you can do with the OP Stack that are *not* currently intended for production use

OP Stack Hacks are not for the faint of heart. You will not be able to receive significant developer support for OP Stack Hacks — be prepared to get your hands dirty and to work without support.

# Overview

Featured Hacks is a compilation of some of the cool stuff people are building on top of the OP Stack!

# Description

OPCraft was an OP Stack chain that ran a modified EVM as the backend for a fully onchain 3D voxel game built with MUD (opens new window).

# OP Stack Configuration

  • Data Availability: Ethereum DA (Goerli)
  • Sequencer: Single Sequencer
  • Derivation: Standard Rollup
  • Execution: Modified Rollup EVM

# Description

Ticking Optimism is a proof-of-concept implementation of an OP Stack chain that calls a tick function every block. By using the OP Stack, Ticking Optimism avoids the need for off-chain infrastructure to execute a function on a regular basis. Ticking Conway is a system that uses Ticking Optimism to build Conway’s Game of Life (opens new window) onchain.

# OP Stack Configuration

  • Data Availability: Ethereum DA (any)
  • Sequencer: Single Sequencer
  • Derivation: Standard Rollup with custom tick function
  • Execution: Rollup EVM
