How it's made
Challenges we ran into While integrating our AI-driven fraud detection with X402 Pay, we encountered a major issue: The AI model began flagging legitimate high-speed X402 Pay transactions as suspicious. X402 Pay’s minimal on-chain metadata and ultra-fast execution created edge cases our model wasn’t trained to understand. This caused false positives, interrupting valid transactions and frustrating users. How We Got Over It To fix this, we took a multi-step approach: Re-trained our AI model using synthetic and real transaction data from X402 Pay to improve recognition of valid payment patterns. Tuned risk thresholds to account for the speed and structure of X402 Pay-specific transactions. Added dual-layer validation, combining AI scoring with rule-based heuristics to reduce reliance on a single detection method. Introduced feedback loops, allowing users to report false positives or suspicious behavior to improve the model over time.
