Lattice
Lattice built open-source software and infrastructure for autonomous onchain worlds, including the MUD framework, Redstone chain, and Quarry infrastructure. In April 2026, it announced it is winding down after five years; Redstone is scheduled to shut down on May 15, 2026.

MUD
Project Links
Description
MUD is an MIT-licensed open-source framework for building onchain applications on Ethereum-compatible networks. It includes development tooling, frontend templates, a development server with contract hot reloading, an automatic indexer, MUD-native account abstraction, and token-standard support; developers can deploy with Lattice’s Quarry environment or compose a stack using EVM chains, ERC-4337 bundlers, and the MUD indexer.Category: Developer Tooling
Redstone Chain
Project Links
Description
Redstone is a blockchain built specifically for onchain games and autonomous worlds, offering features like an automatic MUD indexer, low-latency edge RPCs, and super low transaction fees. It is developed by Lattice in collaboration with Optimism, utilizing an innovative plasma data availability architecture to ensure low fees independent of blob demand.Chains:
Dozer
Project Links
Description
Dozer is a MUD indexer that retrieves MUD Store logs from an Ethereum RPC endpoint, aggregates record updates, splices, and deletions into complete records, and persists them in PostgreSQL. Its JSON HTTP Logs API supports querying records by table ID, key tuple, address, and block number for point-in-time access. It also includes configuration, CLI operation, and PostgreSQL backup and S3-based restore routines.Category: OnChain Data API
Quarry
Project Links
Description
Quarry is a Lattice-built computing environment for onchain worlds. Its integrated stack spans block building through an ERC-4337 bundler, providing end-to-end latency as low as 7ms, passkey-enabled smart-account onboarding with gas sponsorship, low-cost OP Stack transactions using Ethereum Blobs DA and Alt-DA, and planned multi-chain scaling. It is Lattice’s full-stack implementation of MUD’s open Standard World Interface APIs.Category: Blockchain Gaming Infrastructure
