Technical & Commercial FAQ
Common Questions About On-Chain Reputation
Answers to the most frequent questions from CTOs and product leads evaluating our reputation scoring API for their applications.
Our reputation score is a proprietary, multi-dimensional index derived from on-chain activity. We analyze wallet history across Ethereum, Polygon, Arbitrum, and Base for signals including: transaction volume and frequency, DeFi protocol interactions (lending, staking, swapping), NFT holding duration, governance participation, and Sybil-resistance patterns. The model is updated in real-time and normalizes scores on a 0-1000 scale. We do not use off-chain or social data to ensure verifiable, permissionless scoring.
