Programmable blockchain for documentary credits


    Primechain-GUARANTEE is a blockchain repository of Letters of Undertaking, Bank Guarantees, Letters of Credit and other Documentary Credits.

    Primechain-GUARANTEE records are stored in the blockchain in an encrypted form and can only be viewed by banks that have been "whitelisted" by the issuer bank.

    This ensures data privacy and confidentiality while at the same time ensuring that records are shared only between banks that trust each other.

    Each entry on the blockchain is digitally signed by the member bank. Regulator nodes enable real-time supervision by the authorities. The system is API driven and can easily be integrated with the banks' core banking and other legacy systems
