Entity Analysis
The Trust Protocol assigns continuously updated scores to five entity types. Each type has its own scoring focus and signal weight configuration.
Entity Taxonomy
| Entity Type | Description | Scoring Focus |
|---|---|---|
| EOA (User Wallet) | Externally owned account | Transaction patterns, approval behavior, exploit adjacency |
| Smart Contract | Highest-risk entity type | Bytecode, upgrade history, admin key patterns, behavior |
| Token (ERC-20/721/1155) | Fungible & non-fungible assets | Distribution, liquidity, tax behavior, supply changes |
| NFT Collection | Non-fungible collections | Wash trading detection, marketplace authenticity |
| Protocol / DApp | Composite protocol scores | Aggregated scores from all constituent contracts |
Smart Contract — Highest Risk
Smart contracts are the highest-risk entity type and receive the highest AI-derived signal weight (30%). CENCERA analyzes bytecode for exploit variants, proxy upgrade patterns, admin key concentration, and behavioral deviation from the contract's own historical baseline.
Token & NFT Scoring
Tokens (ERC-20/721/1155) are heavily weighted toward market signals (40%) — liquidity depth, Gini coefficient of holder distribution, slippage anomalies, sandwich attack frequency, and sudden supply/tax modifications. NFT collections additionally flag wash trading.
Cross-Chain Entity Profiles
Scores are chain-scoped by default. Cross-chain linkages are established via cryptographic evidence of address ownership. Negative signals propagate more strongly across chains — attackers cannot reset reputation by moving to a different network.
Cold Start Pathway
Nascent entities (<72 hrs old or <50 interactions) enter the Cold Start Pathway: a dedicated scoring pipeline using bytecode analysis, deployer trust inheritance, and initialization transaction analysis. Score is clearly labeled Limited / low-confidence.
CPID — Cencera Persistent Identifier
Each entity is assigned a stable internal CPID that persists across chain reorgs and contract upgrades. Historical score trajectories are tied to the CPID — not the raw address — ensuring continuity even when a contract is upgraded to a new address via a proxy pattern.
Score Trajectory Tracking
The five most recent computation points for any entity — indicates whether the score is stable, improving, or deteriorating. A monotonically increasing risk trend is interpreted as attack staging and immediately elevates the entity to Flagged state.
