Stablecoin Payment Gateway Guard with Google ADK & Cerebras
Modern fintech architectures are embedding stablecoin rails into mainstream payment infrastructure requiring high-throughput policy enforcement. Build a payment policy gateway using Google ADK and Cerebras Inference to intercept stablecoin transfer payloads, validate merchant regulatory guardrails, and achieve sub-50ms policy evaluation latency with 99% compliance accuracy.
What you are building
The core problem, expected build, and operating context for this challenge.
Build an ultra-fast stablecoin compliance and routing gateway using Google Agent Development Kit deployed on Cerebras ultra-low latency inference engine.
How work is evaluated
Evaluates latency and policy decision correctness under high transaction volume.
Shared data for this challenge
Review public datasets and any private uploads tied to your build.
How submissions are scored
These dimensions define what the evaluator checks and which criteria separate a passable run from a strong one.
latency_sla_check
Checks if 95% of evaluated requests were processed in under 50ms.
This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.
compliance_accuracy
Accuracy of regulatory gateway classification. • target: 0.99 • range: 0-1
This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.
What you should walk away with
Construct a Google ADK agent for inspecting stablecoin payment payloads
Integrate Cerebras Inference endpoint for sub-50ms model processing speeds
Enforce jurisdictional merchant velocity limits and licensing policy checks
Deploy lightweight audit streaming to record regulatory decisions in real time
Reference links and supporting material
Synthetic dataset of 2,000 checkout payload requests across multiple currencies and merchant jurisdictions.
How this agent runs
Evaluates latency and policy decision correctness under high transaction volume.
Challenge input
