Stormbit is a decentralized lending protocol on Arbitrum where borrowers post BTC or ETH as collateral and receive fixed-rate loans priced at origination. LTV is only checked at origination borrowers cannot be liquidated during the loan term. Lenders supply USDC into ERC-4626 vaults and earn yield from lending spreads plus hedging premiums. Idle capital earns additional yield via an Aave V3 hook.
