Problem
Bitcoin holders face a difficult choice: sell their Bitcoin and lose upside potential, let their capital sit idle, or give up custody to borrow against it. Traditional lending platforms require handing over control of assets, while stablecoins like USDC and USDT are subject to freezing, blacklisting, and centralized control.
Solution
Uncap Finance enables Bitcoin holders to borrow against their BTC without giving up custody or control. Users deposit WBTC as collateral and mint USDU, a stablecoin backed by over $1 of Bitcoin for every USDU in circulation, ensuring a hard peg to the US dollar. Borrowers set their own interest rate starting at 0.5%, the lowest in DeFi, and can repay anytime to reclaim their Bitcoin. USDU is uncensorable—no blacklists, no admin keys, no centralized control—and can always be redeemed directly from the protocol for $1 worth of Bitcoin. The platform is fully transparent, open source, and audited by ChainSecurity, with no rehypothecation of deposited collateral. Depositors can also earn yield by supplying USDU to the Stability Pool, which generates sustainable APY from borrower interest.
Target Audience
Primary users are Bitcoin holders seeking low-cost, non-custodial liquidity without selling their BTC, as well as DeFi users looking for a censorship-resistant, Bitcoin-backed stablecoin to hold or deploy for yield.
