Model-Based Stamps
Model-Based Stamps use machine learning to evaluate wallet transaction history and assign a score based on patterns associated with real human activity.
ETH Stamp
The ETH Stamp assesses on-chain activity across multiple networks:
- Ethereum Mainnet
- Arbitrum
- Base
- Optimism
- Polygon
- zkSync
The model analyzes transaction patterns, frequency, and diversity to determine a score reflecting genuine human activity.
NFT Stamp
The NFT Stamp focuses specifically on Ethereum Mainnet NFT activity, evaluating factors such as minting, trading, and holding patterns.
Scoring Criteria
The specific scoring criteria for Model-Based Stamps are kept confidential to prevent gaming and manipulation. This ensures the integrity of the scoring system.
Renewal
Like all Stamps, Model-Based Stamps renew every 90 days. Your score may change upon renewal based on your latest on-chain activity.
Important Note
The absence of points from a Model-Based Stamp does not imply that you are a Sybil or bad actor. It simply means there is insufficient on-chain data to assign a score. You can still build your Unique Humanity Score through other Stamp categories.
