The compliance officer reviews 20 cases a day, not 2,000

Every on-chain transaction is scored against sanctions, PEP, mixer exposure, and known-bad-actor wallets in near real-time. SAR-ready summaries are drafted for anything above threshold.

The problem

FCA-registered crypto businesses face the same AML obligations as banks with a fraction of the headcount. Chainalysis and Elliptic give you risk scores but still require a human to contextualise every hit. For a mid-size exchange that's 1,000+ daily flags, and the compliance team burns out or misses a real one.

The system

A triage layer on top of the existing screening vendor. Each flagged transaction is enriched with on-chain history, counterparty reputation, and customer KYC context. An LLM drafts a pre-investigation summary (why it flagged, what the pattern looks like, historical similar cases). The officer reviews the summary and decides, SAR, close, or dig deeper, in under 5 minutes per case.

How it runs

The workflow, end to end.

01

Real-time screening

Every deposit, withdrawal, and transfer is screened against sanctions (OFAC, HMT, UN), PEP, and on-chain risk score vendors on ingest.

02

On-chain enrichment

Counterparty wallet history, mixer exposure, exchange hops, and known-bad-actor proximity are pulled and attached to each flag.

03

Pre-investigation brief

For flagged transactions above threshold, Claude drafts a summary: trigger, pattern, customer risk profile, historical similar cases, recommended action.

04

Officer review

Compliance officer opens the case, reads the 1-page brief, and decides. Evidence, reasoning, and decision are captured for the audit trail.

05

SAR drafting

For cases escalated to SAR, a first-draft SAR is generated against the FCA template with evidence linked. Officer reviews and files.
