Securosys' Transaction Security Broker (TSB) is a hardware security module (HSM) designed to secure and manage digital keys for blockchain and cryptocurrency transactions. It provides a secure environment for key generation, storage, and transaction signing, while offering features for multi-signature setups and compliance with regulatory requirements. The TSB operates as a standalone engine, connecting to an external database and integrating with Smart Key Attributes (SKA)-enabled Securosys Hardware Security Modules to ensure security-critical operations are handled by the HSM. It provides a REST API and internal state management to facilitate the implementation of Securosys Smart Key Attributes.
