Moonstream

Moonstream is an on-chain data infrastructure stack for chain games and web3 projects, with a team in Mountain View, California, composed of data crawlers, a Postgres storage layer and an access-controlled API. The problem it addresses is that game economy design lacks actionable on-chain data: designers need to see token supply, item flows and shifting player behavior, but reading chains directly is costly and incomplete. The platform lets users subscribe to wallet and contract addresses, continuously ingesting the relevant transactions and events, then query and export them through the API.

Use cases include loyalty and reputation systems, forecasting supply and price changes of tokens inside an economy, studying competitors, and distributing rewards to players through Drops. The Moonworm tool builds datasets of market activity, and companion programs flag anomalous behavior. The platform runs its own nodes, covers EVM networks including Ethereum, Polygon and Gnosis, supports testnets, and releases all code under Apache 2.0 so anyone can self-host. Users include Laguna Games and Game7. It is categorized as an on-chain analytics developer platform.
