Challenge

Crypto Banking Off-Ramp AML Verification with Claude Agents SDK

Crypto-to-fiat banking off-ramps require rigorous multi-jurisdictional AML source-of-funds verification to satisfy banking partner compliance mandates. Build an off-ramp AML verification pipeline using Claude Agents SDK to trace wallet lineage, analyze fiat destination account legitimacy, and flag suspicious transactions with 96% accuracy.

Evaluation rubric

How submissions are scored

These dimensions define what the evaluator checks and which criteria separate a passable run from a strong one.

Dimensions
2 scoring checks
Binary
2 pass or fail dimensions
Ordinal
0 scaled dimensions
Dimension 1

evidence_presence_check

Ensures frozen transactions contain non-empty evidence arrays.

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.

Dimension 2

aml_detection_accuracy

Accuracy in correctly flagging suspicious vs legitimate off-ramps. • target: 0.96 • range: 0-1

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.
