Canton Lend

Overcollateralized lending protocol on Canton Network for institutional DeFi.

What It Does

Pool-based lending protocol designed for institutional participants:

• Lending Pools — Deposit tokens to earn yield from borrowers
• Overcollateralized Borrowing — Lock collateral (150%+ ratio) to borrow
• Health Factor Monitoring — Real-time collateralization tracking
• Liquidation Auctions — Bid on undercollateralized positions
• Privacy-Preserving — Loan positions visible only to borrower and pool (Canton sub-tx privacy)

Why Canton for Lending?

1. Sub-transaction privacy — Your lending/borrowing positions are private
2. Atomic settlement — Deposits, borrows, and liquidations execute atomically
3. Institutional compliance — Integrates with Canton Credentials for KYC/AML gates
4. App rewards — 62% of CC emissions (~516M CC/month) flow to Featured Apps
