The problem

Most lending launches start with a whitepaper, a tokenomics model and a date — and a liquidation design that stops paying out in volatile markets. The protocol has to be safe from the first block, and the dashboard has to make risk legible to ordinary users.

How we build it

We model the interest-rate curve and liquidation incentives before writing contracts, then build the suite as isolated markets so a bad asset can never drain the pool. A Next.js dashboard reads indexed data via The Graph and shows health factors, APYs and utilisation in real time.

01

Isolated markets, shared liquidity view

Each asset lives in its own market with its own risk parameters, so a depeg or oracle failure is contained. The dashboard still presents a single portfolio — users see one balance, one health factor, one borrow limit.

A liquidation engine that stays profitable

We simulate 2021–2024 volatility against the proposed close factor and bonus curve, look for scenarios where liquidators would not act, and redesign the incentive to scale with health-factor deficit until bad debt in simulation is near zero.

Audit-ready from the first commit

Invariant and fuzz tests run in CI from week one. The audit pack — threat model, architecture, test coverage — is ready before the auditors are booked, so remediation is a two-week window rather than a launch delay.
