Identity verification (KYC)

ID document verification: OCR of the data fields and the machine-readable zone, tamper and expiry checks, and the document types each customer accepts.
Selfie face match against the document photo, with liveness checks.
Applicants can start on a desktop and switch to a phone by scanning a QR code; data read from the document fills in the application.

Duplicate-identity detection: the same document number or machine-readable zone appearing in more than one application is flagged.

AML screening and monitoring

Screening of individuals and companies for sanctions, politically exposed persons (four levels), adverse media, fitness and probity, regulatory enforcement and insolvency.
Adjustable match sensitivity, aliases, and filters by country and date of birth or incorporation.
Ongoing monitoring whose frequency follows each customer's risk level, from daily to annually, with alerts to the compliance team and a risk recalculation.
Match review: each hit is confirmed, marked a false positive or acknowledged, with a note and an explanation of what matched.
Periodic KYC refresh and reminders before identity documents expire.

Crypto compliance

Wallet screening on 144 blockchains, 24 of them with full coverage, including Bitcoin, Ethereum, Tron, BNB Chain, Solana, Polygon, Arbitrum, Optimism, Base, Avalanche, TON, Cardano, XRP, Stellar, Litecoin and Dogecoin.
Each report gives a risk severity, the counterparty entities and behaviours behind it, and a branded PDF.
Wallets can be screened on their own, inside an application, or through the API.

Risk scoring and workflow

Risk scorecards for individuals and for companies, weighing sanctions and PEP results, FATF lists, the Corruption Perceptions Index, nationality, residency, business type, and IP addresses and devices.
Rules that warn, raise the risk level, ask the applicant for more information or reject, for example when the IP country differs from the declared residence.
KYC requirements built without code: standard and custom fields, questions, uploads, and document forms the applicant fills in and signs.
Four-eyes approval, granular roles and permissions, and an audit trail of every application and every configuration change.
Reports as PDF, exports as CSV and a full data export as ZIP.
