Bitcoin-native DeFi protocol that allows users to deposit BTC and earn on-chain, auto-compounding yield, all while maintaining full control over their assets. It's a secure, transparent platform that operates on the "Bitcoin‑in, Bitcoin‑out" principle—meaning users deposit Bitcoin and receive their principal plus rewards in BTC—without needing to rely on centralized custodians.
