A capital-efficient Bitcoin financing protocol that leverages Aave and Uniswap to provide instant liquidity for BTC purchases
From user loan creation to treasury capital management
User wants to buy 1 BTC, pays down payment in USDC
Treasury swaps USDC → BTC via Uniswap
Supply BTC to Aave, borrow USDC against it
User pays monthly, treasury auto-repays Aave debt
Understanding the mechanics behind the magic
Capital efficiency through DeFi composability
Treasury holds USDC reserves. When a user requests BTC, treasury first checks available balance.
Treasury swaps USDC for WBTC on Uniswap V3 using exactInputSingle for optimal pricing.
BTC is supplied to Aave V3, then USDC is borrowed against it (up to 70% LTV). This can be done iteratively for maximum leverage.
Each iteration: Supply → Borrow → Supply again. Default: 3 iterations at 70% LTV = ~3.4x effective buying power
From creation to final redemption
User specifies BTC amount, down payment %, and tenure. Terms are calculated and locked on-chain instantly.
Chainlink Automation checks payment schedules. Users must keep USDC balance funded. 30-day grace period after each due date.
80% of each payment automatically goes to Aave to reduce debt. Protocol earns spread between loan APR and Aave borrow rate.
Once fully paid, user redeems voucher NFT. Treasury withdraws BTC from Aave and transfers to user.
How USDC and BTC move through the protocol
Our protocol has built-in safety mechanisms to protect against market volatility and ensure your BTC is never at risk of liquidation
Hard cap at 75% LTV ratio
The protocol continuously monitors the Loan-to-Value (LTV) ratio on Aave. If BTC price drops and LTV approaches 75%, the system automatically triggers rebalancing.
Treasury funds are automatically used to repay borrowed USDC on Aave, reducing the debt and bringing the LTV back to safe levels.
Aave liquidation starts at ~83% LTV — we stay well below this threshold
10% buffer always ready
The protocol maintains an emergency liquidity fund equal to 10% of total borrowed amount. This reserve is always ready to be deployed.
In case of sudden BTC price drops, the emergency reserve can be instantly supplied back to Aave to prevent any liquidation event.
Of total borrowed amount — ready for instant Aave debt repayment
Your BTC is always protected by multiple safety layers
