Libre Protocol
Bitcoin-backed USDT lending with one shared, variable-rate pool. Every loan, vault, and liquidation is verifiable on-chain.
USDT Lending Pool
How Libre lending works
One shared, variable-rate pool connects two sides. Borrowers post Bitcoin as collateral to draw USDT; lenders supply USDT to earn the yield borrowers pay. Everything settles on-chain — no custodian, no sign-up, no KYC.
Borrow USDT against your BTC
Lock Bitcoin in a segregated on-chain vault and borrow USDT against it — no selling, no credit checks, no KYC. Repay anytime; your BTC is returned when you do.
- Keep your Bitcoin exposure while unlocking liquidity
- Variable rate set by pool utilization, repay whenever
- A 72-hour window protects you before any liquidation
Supply USDT and earn yield
Deposit USDT into the shared pool and earn a variable yield paid by borrowers. Every loan is backed by real Bitcoin collateral you can verify on-chain.
- Yield scales with how much of the pool is borrowed
- Withdraw whenever the pool has available liquidity
- Backed by segregated BTC collateral, not lent out
Bitcoin prices come from multiple independent feeders run by Libre block producers, each drawing on a different price data provider. The contract takes the median of their reports (at least 3 required), rejecting any feed that deviates more than 10% — so no single operator can move the price. Feeds refresh roughly every 30 seconds, and loans will never liquidate on a price older than 5 minutes: if the feed goes stale, liquidations pause until it recovers.
72-Hour Protection
Price must breach the threshold for a sustained 72h before liquidation executes — time for borrowers to add collateral or repay.
1% Liquidation Discount
Liquidated BTC is sold 1% below market rate — an opportunity for traders to absorb supply as Libre scales.
Contract-Enforced
Smart contracts execute every loan, renewal, and liquidation automatically. Contract upgrades are governed by a 3-of-5 board multisig — no single party can intervene.
