Mud

Mud is a multichain engine for building on-chain, autonomous 3-D worlds across Ethereum, Solana, BNB Chain, Polygon, Arbitrum, Avalanche, Base and other chains.

It is designed to make on-chain game development easier by addressing core challenges such as composability and interoperability.

Developers can use a range of tools, including the Solidity Entity Component System (solecs), the Reactive Entity Component System in TypeScript (recs), and a TypeScript library that keeps contract state in sync with the client state.
