Software you can read.
We open source components for Bitcoin payments, accounting, event sourcing, reliability infrastructure, and more, so builders can inspect, adapt, and reuse them.
Selected projects
The open-source harness Galoy uses to run AI agents against its own banking codebase: credential isolation, human approval gates, and a full record of every action. How we use it →
A framework for persisting event-sourced entities in PostgreSQL. It makes event sourcing possible and practical throughout your whole system.
A double-entry accounting ledger for high-throughput financial applications. It is strongly typed, SQL-backed, and designed so balances reconcile every time.
A durable background job runner backed by PostgreSQL. It schedules and retries asynchronous work with the same transactional safety as the rest of the system.
Outbox and inbox patterns implemented in Rust. It makes message passing between services reliable, solving a problem every event-driven system eventually runs into.
Wallet infrastructure for services that move on-chain Bitcoin at scale. It handles UTXO management, transaction batching, fee estimation, and signing behind a clean API.
Stablesats infrastructure that lets Bitcoin deposits hold USD-denominated value. It calculates target liabilities from ledger activity and hedges exposure through exchange integrations.
