Interlay is building its flagship product, "InterBTC," a fully collateralized one-to-one Bitcoin-backed asset that enables interoperability between multiple blockchain ecosystems while preserving Bitcoin's censorship-resistant nature. Interlay v2 proposes introducing native DeFi functionality to the network: a decentralized AMM-based exchange (Uniswap v2 model and Curve Stableswap) paired with a liquidity protocol for BTC borrowing and lending (Compound v2 model). By creating markets catering to Bitcoin holders and building deep liquidity in these protocols, Interlay will enable easy, one-click access to Bitcoin-centered DeFi use cases, ranging from simple passive liquidity provision to tailored long/short leverage positions.
