How Chainalysis and Blockchain.com Partner to Improve Compliance Efficiency
We wanted a solution that would help our analysts focus on meaningful risk while giving us greater control over the way we monitor activity across our platform. Chainalysis brought together the flexibility, intelligence, and depth of data we were looking for, and the partnership has allowed us to make our compliance operations even more efficient, effective, and resilient as we continue to scale.”
Effective compliance isn’t about generating the most alerts. It’s about giving investigators the right information, at the right time, so they can focus their attention where it matters most.
That principle is at the heart of Chainalysis’ partnership with Blockchain.com, one of the digital asset industry’s largest and longest-running platforms, powering 95M+ wallets and more than $1.1 trillion in crypto transaction volume.
As Blockchain.com continued to scale its global operations, the company saw an opportunity to enhance the technology supporting its sophisticated compliance program. By partnering with Chainalysis, Blockchain.com gained greater flexibility in transaction monitoring, improved the quality of signals reaching its Financial Intelligence Unit (FIU), and reduced time spent on non-actionable activity.
Chainalysis’ intelligence screening successfully flagged genuinely risky customer transactions for FIU review when tested in a sample population. At the same time, the Chainalysis tools saved FIU investigators’ time by flagging fewer false positives than their prior provider did.
Giving investigators better signals
Operating across multiple jurisdictions, Blockchain.com needed transaction monitoring technology that could scale with its business while giving investigators greater configurability and more sophisticated detection capabilities.
The goal was to help analysts focus their time on meaningful risk rather than low-value reviews. That made Chainalysis a natural fit.
Why Blockchain.com chose Chainalysis
- Configurable, explainable rules. Chainalysis KYT splits risk categories into independent rules with adjustable levers for direction, exposure type, USD amount, and percentage of transfer. This gives compliance teams granular control over what triggers an alert and why.
- Behavioral and continuous monitoring. Rather than relying solely on static address lists, Chainalysis surfaces alerts based on behavioral patterns and ongoing monitoring, catching risks that point-in-time screening misses.
- Court-tested data. Chainalysis data has been tested in legal proceedings, with specific typology categories that produce stronger SAR evidence and align with how regulators and law enforcement think about risk.
Together, these capabilities allowed Blockchain.com to refine its screening environment while maintaining strong risk controls.
Fast migration, immediate results
The migration moved fast. Blockchain.com kicked off implementation in mid-February, ran a shadow testing window against the prior provider, went live in April, and reached full production by June. The entire transition took approximately ten weeks.
The results speak for themselves: 100% hit rate of truly actionable cases with 0 false positives.
To quantify the significance of the partnership, Blockchain.com compared 289 pending cases with a Chainalysis screening of the same underlying customer transactions. Of these 289, 70 were known to be truly actionable cases that warranted attention; the other 219 were non-actionable and should not have generated alerts in the first place.
The results of the Chainalysis screening:
Chainalysis correctly identified and generated alerts for the 70 cases that warranted genuine attention (100% accuracy). On this tested population, Blockchain.com saw the false positive rate drop from 76% down to 0% using Chainalysis. The alerts Chainalysis didn’t generate aligned precisely with the cases Blockchain.com’s own investigators determined were non-actionable. The alerts it did surface were the ones that warranted attention.
These results are based on this specific tested population and will continue to be validated as additional screening and investigation data becomes available.
Better signal, not less coverage
A natural question when alert volume drops is whether the system is simply less sensitive. Blockchain.com’s experience suggests the opposite.
After going live with Chainalysis, Blockchain.com observed that overall alert volume was actually higher in certain areas that were more actionable as compared to before. With a few straightforward configuration adjustments, such as turning off broad, low-signal risk categories, the team reduced noise further without sacrificing detection of genuine risk.
For compliance leaders evaluating their own screening infrastructure, Blockchain.com’s experience reinforces a principle the industry is still internalizing: the quality of screening, not the quantity of alerts, is what distinguishes effective programs.
A partnership designed to evolve
Blockchain.com’s work with Chainalysis reflects a shared commitment to strengthening how digital asset businesses identify, understand, and respond to risk.
By combining Blockchain.com’s experienced compliance organization with Chainalysis’ blockchain intelligence and transaction monitoring technology, the partnership is helping investigators spend less time on unnecessary reviews and more time on activity that merits their expertise.
For Chainalysis, that is what an effective technology partnership should deliver: better information, greater operational efficiency, and tools that can evolve alongside the teams that rely on them.
As Blockchain.com continues to scale, Chainalysis is proud to support its compliance teams and continue building a safer, more trusted digital asset ecosystem together.
