Project Background and Challenges

The client is a DeFi team and needs a lending protocol supporting multi-chain deployment, covering lending pools, interest rate models, and automated liquidation. We undertake contracts, oracle integration, and front-end solutions.

The core challenge lies in the security of liquidation logic and the consistency of multi-chain behavior— The clearing engine must be stably triggered under extreme market conditions and not maliciously manipulated, while the contract must maintain consistent performance across different chains. The contract is audited by a third party before being listed on multiple chains.

The scope we undertake

Lending pools and interest rate model contracts, automated clearing engines, oracle integration, The Graph index, and frontend.

Scope 1

Key technical decisions

Decision 01
Liquidation engine design
Clearing logic is independent and modular, stable triggers during extreme market conditions, and anti-manipulation design prevents malicious liquidation arbitrage.
Decision 02
Multi-chain consistency
Contracts maintain consistent behavior when deployed across multiple chains, reducing cross-chain variance risks through unified deployment and parameter management.
Decision 03
Pre-launch audit
Core contracts are listed only after third-party security audits, ensuring no luck in fund security.
