PROVEN METHODS
Our Anti-Sybil Engineering Toolkit
We deploy a multi-layered defense system combining on-chain analysis, behavioral heuristics, and cryptographic proofs to protect your token distribution from manipulation and ensure genuine user adoption.
01
On-Chain Identity Graph
We map wallet relationships and transaction histories using proprietary algorithms to detect coordinated Sybil clusters, identifying fake accounts before they can claim rewards.

02
Behavioral Analysis Engine
Our system analyzes user interaction patterns (timing, sequence, gas usage) to flag inorganic behavior that simple stake-based filters miss.

Custom Reputation Scoring
We build weighted scoring models that evaluate wallet age, NFT holdings, governance participation, and DeFi activity to create a Sybil-resistant reputation threshold.

MEASURABLE IMPACT
Business Outcomes of a Fair Distribution
A Sybil-resistant distribution isn't just a technical feature—it's a strategic business asset. Our design delivers concrete results that protect your token's value, build a loyal community, and accelerate growth.
01
Protected Token Value
Minimize immediate sell pressure from airdrop farmers. Our Merkle-based claim systems and on-chain verification ensure tokens reach real users, stabilizing your tokenomics from day one.

Authentic Community Growth
Convert airdrop recipients into active protocol participants. By rewarding genuine past interaction (e.g., on-chain activity, governance), we build a foundation of engaged, long-term holders.
