The Sixpence product suite
Built for institutions
that cannot be wrong.
Every number, back to the transaction it came from. Sixpence turns raw blockchain, exchange and banking data into one record you can defend, and builds the products that read from it: LedgerCore, the engine; LedgerWatch for market oversight, LedgerBrain for counterparty screening and Coinfig for tax.

Market oversight for supervisors.
LedgerWatch is built on LedgerCore for regulators, central banks and forensics teams.

Every counterparty, traced and scored.
LedgerBrain is our AI-powered risk suite. Graph intelligence follows value through the noise and explains what it finds: KYT, counterparty and Travel Rule checks for compliance teams, and Know-Your-Agent verdicts for the machines that now move value. A compliance team is screening transactions about ten minutes after creating an account, through the console. No integration project first.

Crypto tax that holds up.
Coinfig is built on the same record we run in regulated environments. It ingests exchange CSVs, read-only APIs and wallet addresses, rebuilds the full transaction history, applies configurable tax rules and generates accountant-readable report packs. South Africa first, built to follow you across borders.
