KAT (KaelAi Trust) Scores measure behavioral trustworthiness across five independent dimensions. Think of it as a credit bureau for the agent economy - but built on onchain behavior, not identity.
How long the wallet has been active and transacting. Older wallets with consistent history score higher.
Pattern stability over time. Erratic activity, sudden large transactions, or behavioral shifts reduce this score.
The trustworthiness of wallets and protocols this address has interacted with. Good neighbors matter.
Depth and breadth of protocol engagement. Active DeFi participants across verified protocols score higher.
Transaction value variance and patterns. Extreme spikes or anomalous value ratios signal potential risk.
| Grade | Score Range | Label | Recommended Action |
|---|---|---|---|
| AAA | 90-100 | Exceptional trust | Proceed with full commerce limits |
| AA | 80-89 | High trust - established wallet | Proceed with confidence |
| A | 70-79 | Good trust - active participant | Standard commerce limits apply |
| BBB | 60-69 | Moderate trust - verified active | Proceed with standard limits |
| BB | 50-59 | Below average - limited history | Apply reduced limits |
| B | 40-49 | Low trust - thin or erratic history | Require additional verification |
| CCC | 0-39 | Very low trust - high risk signals | Decline or require full KYC |
