DeFine

DeFi wallets can contain many sources of risk across positions, token permissions, assets and wallet activity.

DeFine brings these signals into one place so users can quickly see what needs attention, why it matters, and what to inspect first.

Users can monitor the wallet as a whole - including unusual activity and security risks - or follow specific DeFi positions and assets, with alerts when relevant risk appears or changes.

Underneath, DeFine tracks risk state over time rather than only showing the current blockchain state. On Arbitrum, the working implementation analyzes real Aave V3 positions, evaluates Health Factor risk deterministically, stores block-pinned historical snapshots, persists risk evaluations, and supports configurable monitoring thresholds.

DeFine uses a modular risk architecture designed to expand from individual risk modules into a wallet-level Risk Summary that connects meaningful changes with context and priority.

Reusable risk modules and EVM infrastructure utilities are also published through the open-source define-kit.

During the Buildathon, DeFine evolved from an existing Aave V3 risk-analysis foundation into a stateful risk-monitoring system on Arbitrum.

I added historical risk snapshots and position history, allowing users to inspect how an Aave V3 position and its risk change over time. Alongside this stateful history, DeFine continuously monitors Health Factor risk: users can configure the risk threshold they want monitored, while the system automatically re-evaluates the position on a schedule, tracks whether the condition is met, and persists the monitoring state over time.

The monitoring architecture is modular: position-specific risk modules produce normalized risk state that can use the same persistence, history and monitoring pipeline. Aave V3 Health Factor is the first working module, while the architecture is designed to extend to additional DeFi positions and risk types without rebuilding the monitoring system for each one.

I also developed and prototyped the wallet-level product flow around a clearer question: “What in this wallet needs my attention right now, and why?” The new Risk Summary, Activity view and risk-change explanations demonstrate how DeFi position and wallet-security signals can be brought together, given context and prioritized instead of presented as isolated alerts.

Cross-risk, unusual-activity and risk-attribution scenarios in the current UI are synthetic and explicitly marked Demo. The underlying Arbitrum Aave V3 data, Health Factor evaluation, historical snapshots and monitoring state are real.
