# RiskScore™: AI-Powered Wallet Threat Scoring

> NZOChain's RiskScore™ assigns a 0–100 threat level to your wallet based on approvals, contracts, and activity patterns. Learn what each score means.

Your RiskScore™ is a live, composite number between 0 and 100 that reflects the current threat exposure of your wallet. Unlike a one-time security check, the score updates continuously as NZOChain detects new approvals, contract interactions, and behavioral signals. A lower score means your wallet is clean; a higher score means action is needed.

## Score bands and what they mean

NZOChain maps every score to one of four bands, each with a clear recommended response.

| Score  | Band      | Status                                    | Recommended action                                                            |
| ------ | --------- | ----------------------------------------- | ----------------------------------------------------------------------------- |
| 0–30   | Safe      | No significant threats detected           | No action required — review periodically                                      |
| 31–60  | Warning   | Suspicious signals present                | Review flagged approvals and contract interactions                            |
| 61–85  | High Risk | Dangerous approvals or contracts detected | Revoke risky permissions immediately                                          |
| 86–100 | Critical  | Active threats requiring immediate action | Act now — revoke all dangerous approvals and disconnect from suspicious dApps |

<Warning>
  A Critical score (86–100) means NZOChain has detected active threats against your wallet. Do not sign any new transactions until you have reviewed and resolved the flagged issues. Go to your **Approval Manager** and revoke dangerous permissions immediately.
</Warning>

## What contributes to your score

Your RiskScore™ is calculated from multiple threat signals simultaneously. NZOChain weighs each factor based on severity and combines them into a single score.

<CardGroup cols={2}>
  <Card title="Active approvals" icon="key">
    Unlimited or high-value token approvals granted to external contracts. The more uncapped approvals you have, the higher your score.
  </Card>

  <Card title="Contract risk flags" icon="file-contract">
    Interactions with contracts identified as malicious, unverified, or associated with known exploit patterns.
  </Card>

  <Card title="Phishing signals" icon="fish">
    Connections to domains or contracts that match known phishing infrastructure, fake dApps, or address-spoofing patterns.
  </Card>

  <Card title="Behavioral anomalies" icon="chart-line">
    Unusual activity patterns such as rapid approval sequences, transactions to newly deployed contracts, or signs of front-running bots.
  </Card>
</CardGroup>

## AI-powered analysis

<Info>
  AI-powered analysis is available on the **Premium** plan.
</Info>

On the Premium plan, NZOChain applies advanced machine-learning models to your wallet's activity history. These models detect threats that have no known signature — emerging attack patterns, obfuscated malicious contracts, and zero-day phishing campaigns. Standard analysis relies on known threat databases; AI analysis extends coverage to novel and evolving threats your wallet may not have encountered before.

## RiskScore history

<Info>
  RiskScore history is available on the **Pro** and **Premium** plans.
</Info>

Pro and Premium users can view a full timeline of their RiskScore over time. History lets you:

* Identify exactly when your score changed and what caused the change
* Track the impact of revoking approvals or removing risky connections
* Audit wallet activity for a specific period, useful for compliance or personal review

The history view is accessible from your dashboard under **Wallet Overview → Score History**.

## How scores update

Your RiskScore™ recalculates in real time whenever:

* A new token approval is detected on any monitored chain
* You interact with a contract that has risk signals
* NZOChain's threat database adds a new entry matching your wallet's connections
* A phishing or drainer campaign is identified that targets contracts you've interacted with

You do not need to manually refresh or re-scan — the score stays current automatically.
