Galoy is building the core banking system for software-native banks. One ledger for dollars, euros, Bitcoin, and stablecoins.
The Galoy core is written in Rust around an event-sourced, double-entry ledger. Capabilities are built as modules with explicit contracts, enforced at compile time, and the whole system is deployed and operated as one.
Inside the core:
- Multi-currency ledger: dollars, euros, Bitcoin, and stablecoins in one double-entry accounting model
- Payments: ACH, Fedwire, RTP and FedNow, Lightning, and major stablecoins
- Digital-asset lending: term loans and lines of credit collateralized by digital assets, with real-time collateral marking and configurable margin calls.
- Governance: maker-checker approvals wired into credit and withdrawal flows, with every action logged
- Custody: custody-independent by design. Banks bring their own qualified custodian.
A de novo institution starts on the Galoy core directly. An incumbent bank can adopt a single module deployed alongside the core it runs today.
We open source components for Bitcoin payments, accounting, event sourcing, and reliability infrastructure so builders can inspect, adapt, and reuse them:
The team behind the Galoy core ran the Bitcoin Beach Wallet in El Salvador at national scale from 2019 to 2025. Galoy is ISO 27001:2022 certified.
