MUD, our application framework, is open-source and is enabling various projects that run on Optimism or the OP Stack, including Words3, an on-chain infinite scrabble (https://words3.xyz), Primodium, an onchain resource management game (https://www.primodium.com/), Sky Strife, Kamigotchi, and more. It was also the framework of choice at the ETHGlobal Autonomous Worlds Hackathon sponsored by Optimism, ETHGlobal, Protocol Labs, and Lattice that took place in May. OPCraft, our onchain voxel game, was fully open-sourced and launched on the OP Stack in October last year. In 2 weeks, it saw 3.5m tx (~2x the Bedrock testnet) and helped uncover multiple bugs in the OP Stack. It also showed developers the OP Stack's potential for gaming and complex apps (even featuring in a WIRED article!)
