BRIDGE // Custody
Institutional
custody.
HSM-backed key management, multi-signature policies, and HD wallet infrastructure. Secure digital assets, tokenized securities, CBDCs, and stablecoins under a unified policy engine.
Custody capabilities
Every operation — key generation, signing, approval, transfer — is recorded on the distributed ledger with cryptographic proof.
HSM Key Management
Private keys generated, stored, and operated within hardware security modules. Keys never exist in plaintext outside tamper-resistant hardware.
Multi-Signature Policies
Configure M-of-N approval thresholds per asset class, transaction value, or counterparty. Approval requests auto-expire to prevent stale authorizations.
HD Wallet Architecture
Deterministic derivation following BIP-32 and BIP-44 standards. Generate unlimited child addresses from a single master key with cryptographic isolation between accounts.
Real-Time Deposit Indexing
Continuous on-chain monitoring with automatic detection, validation, and crediting. Configurable confirmation thresholds per asset type.
Multi-Chain Support
Custody across EVM (Ethereum, Polygon, BSC), Bitcoin, and Solana chains. Unified interface regardless of the underlying network.
Policy Engine
Programmable custody policies enforce withdrawal limits, velocity checks, whitelisted destinations, and time-based restrictions at the infrastructure level.
Audiences
Built for every regulated custody buyer
The platform is the same; the operating posture and reporting expectations are not. Pick your audience.
For banks
Bridge Custody is built so a regulated bank can hold digital assets on behalf of customers without rebuilding its risk and operations playbook. HSM-backed key material, segregation of customer assets, multi-signature approval flows, and audit trails the regulator already understands.

Get Started
Three steps to
institutional custody.
Onboard Your Institution
Complete institutional verification, configure your tenant environment, and establish custody policies. Define multi-sig thresholds and asset allowlists.
