BRIDGE // Custody / CBDC
Wallet & custody
for CBDC.
Central bank digital currency programs need custody and wallet infrastructure that can scale to a national population while keeping the issuing authority in firm control. Bridge provides the underlying stack: HSM-backed key management, hierarchical wallets, per-tier policy enforcement, and supervisor dashboards.
What CBDC programs need
A CBDC stack has to do three things at once: scale to retail volumes, give the central bank surgical control over policy, and give privacy and protection to the end user. The infrastructure layer has to support all three without forcing trade-offs.
Hierarchical deterministic wallet derivation that lets the central bank manage millions of accounts without millions of keys.
Per-tier limits, holding caps, and transaction restrictions enforced before they reach the ledger.
Real-time supervisory dashboards showing aggregate flows, exposure concentrations, and policy breaches.
The CBDC stack
Bridge Custody slots in alongside the rest of the Bridge platform — settlement, identity, and supervisory tooling — to give a central bank a complete CBDC operating system.
FIPS 140-2 Level 3 HSM-backed key storage with documented key ceremonies for issuance authority keys.
Hierarchical deterministic wallet structures so the central bank can manage population-scale accounts without per-account key material.
Tiered identity verification with corresponding holding and transaction caps. Anonymous low-tier wallets graduate as identity is added.
Holding limits, velocity controls, sanctions enforcement, and offline capability all configurable per population segment.
Real-time aggregate views of money supply, velocity, regional concentration, and policy compliance.
Configurable privacy budgets that balance end-user protection with the central bank's supervisory mandate.
