The problem ShieldFi solves
Manage CDP wallets with confidence — ShieldFi helps users open, monitor, and protect collateralized debt positions, with AI-driven alerts to prevent sudden liquidation.
Send low-fee, secure crypto payments — Using X402 Pay, ShieldFi lets people make fast wallet-to-wallet and merchant payments with real-time fraud protection.
Monitor portfolio risk in plain language — The AI agent simplifies complex DeFi data, so users can ask questions like “Is my position at risk?” or “How can I reduce my debt?” and get clear answers.
Earn via referrals — Users can safely share their referral links, knowing rewards are tracked transparently and securely on-chain.
Track transaction history with trust scores — Every payment, CDP action, and referral is logged securely, giving users a verifiable, tamper-proof record.
Challenges I ran into
While integrating X402 Pay with ShieldFi’s fraud detection engine, we ran into a major challenge:
Our AI risk scoring system was mistakenly flagging valid X402 Pay transactions as suspicious.
This happened because X402 Pay’s low-latency transactions and minimal on-chain metadata confused the AI model, which was originally trained on traditional blockchain transaction patterns (e.g. Ethereum, Polygon).
How We Solved It
We refined our AI model by:
Simulating hundreds of X402 Pay transaction scenarios to generate a richer dataset for training.
Tuning the risk scoring thresholds specifically for X402 Pay transaction characteristics (speed, structure, metadata).
Adding a dual-layer validation — combining AI analysis with lightweight rule-based checks (e.g. verifying transaction destination against user’s trusted contacts list).
We also implemented real-time feedback loops — where users can mark transactions as safe or suspicious — helping improve detection over time.
