FlashStack is an open‑source, atomic flash‑loan protocol built for the Stacks blockchain (Bitcoin Layer 2) that lets users borrow sBTC without collateral, execute any on‑chain strategy — such as arbitrage or liquidation — and repay the loan plus a small fee in a single transaction, reverting automatically if repayment fails. It’s aimed at developers and DeFi builders who need instant, trustless capital for on‑chain strategies, while security‑focused enterprises can leverage its hardened testnet implementation as a foundation for production‑grade, audited flash‑loan services.
