Lend: Hyperscalable capital efficient lending protocol on Sonic SVM.

Lend is a decentralized lending protocol built on Sonic SVM, optimizing capital efficiency and scalability for DeFi users. Designed to leverage Sonic’s HyperGrid sharding, it offers a scalable and robust lending solution.

Key Features

• Enhanced Capital Efficiency: Continuous matching with atomic splitting ensures funds are utilized effectively, pairing large positions with smaller counterparts seamlessly.
• User Convenience: Stale positions are refunded automatically (99.5%), with a 0.5% fee to deter spam—no manual claims required.
• Risk Management: Loans require 1.5x collateral minimum, with liquidation at 1.2x, ensuring stability without oracles.
• Shard Isolation: Sharding enhancing performance, scalability and security across the protocol.
• Sonic Integration: Built for Sonic SVM’s low-cost storage and parallel execution, delivering high performance at scale.

How It Works

1. Borrowers offer asks with collateral and rate caps.
2. Lenders submit bids with loan amounts, rates, and durations.
3. Real-time matching pairs bids and asks atomically.
4. Loans accrue interest; repay or face liquidation if health drops below 1.2x.
5. Admin withdraws fees from shard-specific treasuries.

Lend/Sonic Advantage

Lend taps into Sonic SVM’s sharding and efficiency to deliver a lending protocol that’s secure, scalable, and capital-efficient—ready for the future of DeFi.

Steps to Test Lend Contract

Install the Following:

• Anchor (v0.29.0)
• Solana CLI (v1.18.26)
