Licensed financial institutions aren’t just given a green light to handle money—they’re trusted to uphold the integrity of the financial system. That means building infrastructure that can monitor transactions, detect risks, and block suspicious activity in real-time.

At Striga, we operate at the intersection of traditional banking and decentralised finance. With this comes the responsibility to build a crypto monitoring system that meets high compliance standards—capable of tracking every transaction and passing scrutiny from regulators like the Financial Intelligence Unit of Estonia.

In practice, this means we must be ready at any time to demonstrate the due diligence performed on any given crypto or fiat transaction.

When it comes to AML crypto monitoring, manually reviewing thousands of daily transactions isn’t just inefficient—it’s impossible. That’s why building a scalable transaction monitoring system was one of our earliest priorities.

Before tools like Flagright existed, we built our own in-house system. If you're a regulated institution today, we’d recommend buying over building—unless you have a deep engineering bench and appetite for complexity.

We’ve broken our transaction monitoring setup into three key categories: blockchain monitoring, fiat transaction tracking, and user risk profiling.

Blockchain-based crypto transaction tracking
‍
Unlike fiat, crypto operates on transparent public ledgers. But transparency doesn’t equal clarity. Crypto’s semi-anonymous nature means platforms like Striga rely on analytics partners—like Chainalysis, Scorechain, Elliptic, Crystal, and TRM Labs—to flag risky activity.

This is core to crypto transaction tracking. These tools help us trace funds, detect anomalies, and prevent transactions linked to illicit sources.

Fiat transaction monitoring

Monitoring fiat is more straightforward but just as critical. It includes:

• Bank transfers (between financial institutions)
• Card transactions (via Visa/Mastercard rails)

Both must be screened for anomalies using velocity patterns, value thresholds, and historical context.

User risk profiling and monitoring

You can’t separate crypto monitoring from user behaviour. Effective compliance starts with:

• KYC – Verifying identity, location, and documentation
• Risk profiling – Based on geography, occupation, transaction history, and source of funds
• Velocity monitoring – Tracking abnormal spikes in frequency or value
• Ongoing KYC – Updating records and flags in real-time

And yes, we do sanctions screening too—automated and real-time, with any matches resulting in immediate action.

This stuff is hard—and that’s the point.
The cost of getting crypto monitoring wrong is existential. From fines and freezes to revoked licences and criminal liability, the stakes couldn’t be higher.

At Striga, we’ve made a choice: compliance over shortcuts. Our engineering, compliance, and product teams work hand-in-hand to stay ahead of evolving risks and regulations.

Crypto monitoring isn’t just about staying compliant. It’s about building a platform that can scale, sustain, and survive
