Transaction Fraud Triage Agent
Build an agent that watches the payment stream, weighs the risk signals on each flagged transaction, and decides in real time whether to clear it, hold it, escalate it, or block the card — freezing accounts only when it truly matters.
Challenge Overview
This challenge puts you on a card issuer's fraud monitoring desk, where an agentic fraud bot has to clear a burst of 6 flagged transactions— fast.
For each transaction the agent tallies the risk signals and picks a graduated response — Clear, Hold for review, Escalate to fraud team, or Block card— records the reason, and decides whether the case warrants freezing the account. The challenge trains the balance every fraud system fights: stopping real fraud without over-blocking good customers.
The 5 Risk Signals
Count how many of these are present on each transaction.
Decision Policy

ClearWhen to Freeze the Account
Independent of the action — reserve a full freeze for high-value, high-risk cases.
Amount over $5,000 AND 2+ risk signals
Freeze accountStep-by-step Instructions

2. Count how many of the 5 risk signals are present
3. Map the signal count to an action (Clear / Hold / Escalate / Block)
4. Select the reason that matches the risk level
5. Decide whether to freeze the account (over $5,000 and 2+ signals)
6. Submit and work through all 6 transactions for your score

Common mistakes
• Blocking a card that has only one mild signal
• Clearing a transaction with several stacked signals
• Freezing the account on a small-value risky transaction
• Forgetting to freeze a high-value, high-risk case
• Miscounting signals and landing one tier off
