What is MUD?
MUD is an open-source engine for building onchain applications and autonomous worlds on Ethereum. Built by Lattice, MUD reduces the complexity of building Ethereum apps with a tightly integrated software stack. Developers can get started by running a single command and choosing from frontend templates including React and Three.js. MUD includes an automatic indexer, native account abstraction, and support for token standards. First released in 2022, MUD has been used by developers and game studios to build production applications with millions of onchain entities. All MUD interfaces with peripheral services—indexers, blockchains, ERC-4337 bundlers—are openly accessible and under standardization. Developers can launch with Lattice's Quarry environment for ultra-low latency or design a custom stack with any EVM blockchain.
