The LENX Protocol is an omnichain Bitcoin liquidity market, using native Bitcoin and Frax BAMM to enhance BTC liquidity in DeFi. It introduces xBTC and XD tokens, allowing for both algorithmic and user-defined interest rates. LENX provides deep liquidity for xBTC pools, serving as building blocks for innovative BTC and BRC-layered protocols. The protocol supports instant withdrawals of native BTC for suppliers and customizable borrowing options for users, with no mandatory maturity dates. Core features include no liquidation risks, the absence of oracles for lending decisions, and interest accumulation mechanisms for both suppliers and borrowers.
