Build the Auditable Systems for a Legit Sweepstakes Casino
Yes, completely legit sweepstakes casinos operate using provably fair systems and strict compliance automation. Their legitimacy depends on automating complex state-by-state rules and financial transaction monitoring.
This is not a legal problem but an engineering one. The challenge is building auditable software that enforces rules from 50 different jurisdictions in real time for every user action. Off-the-shelf platforms lack this granularity, and manual review is too slow and error-prone to be a viable defense during an audit.
We built the core operational engine for a gaming startup with 50,000 users. The system automated their user onboarding, transaction monitoring, and compliance checks, processing over 1,000 KYC verifications per day. The build took 4 weeks, and their manual review queue dropped by 95%.
What Problem Does This Solve?
Many startups try to use white-label casino platforms. These platforms treat compliance as a simple checklist, often blocking entire states like Washington or Michigan without nuance. This means you lose legitimate customers because the platform cannot distinguish between a banned promotion type and a permissible one within the same state law.
A common failure point is Know Your Customer (KYC) and Anti-Money Laundering (AML) checks. A small operations team trying to manually verify IDs and monitor transactions for thousands of users creates a 48-hour onboarding delay. This backlog frustrates users and makes it impossible to spot sophisticated bonus abuse or circular funding patterns in real time. A manual process cannot scale past a few hundred users without significant compliance risk.
Even with a third-party payment processor like Stripe, their built-in fraud detection is designed for e-commerce, not regulated gaming. It will catch stolen credit cards but miss a user creating 10 accounts to abuse a first-deposit bonus. Without a system that understands the specific rules of sweepstakes gaming, you are exposed to both financial loss and regulatory penalties.
How Does It Work?
We start by modeling your entire operational workflow and state-by-state compliance rules into a Supabase Postgres database. This schema becomes the single source of truth, defining which actions are permissible for a user based on their location, verification status, and transaction history. Every business rule from your legal counsel is translated into a specific database constraint.
We then build a central compliance engine using Python and FastAPI. This API provides secure endpoints for every critical user action: registration, document upload, deposits, and prize redemption. For complex rule interpretation, we use the Claude API to parse updates from state gaming commission websites and flag potential changes to your legal team, ensuring your rule engine never goes stale. An automated KYC check that previously took 2 days now resolves in 12 seconds.
The engine integrates with specialized third-party services using the httpx library for reliable, asynchronous API calls. We connect to a KYC provider like Veriff to verify identities and a service like Chainalysis for crypto transaction monitoring. These integrations feed data directly into our FastAPI service, allowing a single API call to check a user against 3 different external systems and your internal rules simultaneously with a P99 latency of under 800ms.
This entire system is deployed as a series of serverless functions on AWS Lambda, which costs under $100 per month for up to 1 million transactions. Every decision made by the engine is recorded with `structlog` to a dedicated, immutable log table. This creates a complete, timestamped audit trail you can provide to regulators to prove your operational integrity.
What Are the Key Benefits?
Onboard Users in 15 Seconds, Not 3 Days
Our automated KYC and compliance check pipeline clears new users for play almost instantly. This eliminates the onboarding backlog that causes user churn.
One-Time Build Cost, Not a Revenue Share
We deliver the complete system for a fixed price. You avoid the 5-15% gross gaming revenue fees charged by white-label platform providers.
You Own The Audit Trail and Source Code
We deliver the full Python codebase to your company's GitHub repository. You have a permanent, verifiable record of every compliance check and transaction.
Alerts When State Laws Change
An AI agent monitors gaming commission websites for regulatory updates. It flags changes affecting your operations so your legal team can review and adapt proactively.
Integrates With Your Specific Vendors
The system is built to connect to your chosen KYC provider, payment processor, and analytics tools. We write the specific API integrations for your stack.
What Does the Process Look Like?
Compliance Mapping (Week 1)
You provide your legal team's state-by-state rule matrix. We translate this into a detailed technical specification and a database schema, which you approve before any code is written.
Core Engine Build (Week 2)
We build the FastAPI service with all compliance logic and internal rules. You receive API documentation and a testable endpoint to see the core decision engine in action.
Integration and Deployment (Week 3)
We connect the engine to your third-party APIs for KYC, AML, and payments. The full system is deployed to a staging environment for end-to-end testing.
Testing and Handoff (Week 4)
We conduct load testing and help your team run simulated user scenarios. After your final approval, we deploy to production and hand over the source code and runbook.
Frequently Asked Questions
- What affects the cost and timeline of a build?
- The primary factors are the number of third-party integrations (KYC, payment gateways) and the complexity of your prize and bonus logic. A simple system with one KYC provider and standard redemption rules is a 4-week build. A system integrating multiple payment types with tiered bonus structures may take 6 weeks. We provide a fixed-price quote after our initial discovery call.
- What happens if a third-party service like our KYC provider goes down?
- The system is designed for graceful failure. If a KYC check API is unresponsive, the user's onboarding is paused, and they are shown a message to try again later. The system retries the check automatically every 15 minutes. It will not block other functions like existing users playing games. Our monitoring provides immediate alerts on third-party API failures.
- How is this different from buying a white-label casino platform?
- White-label platforms force you into their rigid, one-size-fits-all compliance logic and often take a percentage of your revenue. With a custom build, you own the code, control the logic, and can adapt instantly to new regulations or business opportunities. There are no ongoing revenue-share fees, only minimal, direct cloud hosting costs.
- Do you provide legal advice on sweepstakes laws?
- No. We are not a law firm and do not provide legal guidance. We are engineers who build systems that implement the exact business rules provided by your legal counsel. Our process begins with the compliance framework that you and your lawyers have already established. We build the software that enforces your rules.
- Is the AI making autonomous compliance decisions?
- No. The AI's role is assistive, not autonomous. It parses public legal documents to flag potential regulatory changes for human review. All final business logic and compliance rules are explicitly coded into the FastAPI application based on your team's decisions. This ensures every action is fully deterministic and auditable, not a black box.
- What do we need to provide to get started?
- The key inputs are your legal team's compliance matrix detailing rules for each US state and API keys for any third-party services you plan to use (like a KYC or payment provider). We also need read-only access to your user database to integrate the compliance engine. We can begin mapping the system architecture from the compliance matrix alone.
