Solution · Super custodian
Super custodian HSM management at institutional scale.
Enterprise HSM and MPC infrastructure for key custody, policy controls, and secure enclave provisioning across wallet programs.
FIPS 140-2
HSM attestation & compliance
MPC protocol
Threshold signing & keygen
Fireblocks
Institutional custody integration
Three layers. One custody stack.
HSM infrastructure, policy controls, and secure provisioning, every module deploys independently or as part of the full super custodian stack.
HSM / MPC Infrastructure
Clustered HSM and MPC key infrastructure with hardware attestation, quorum policies, and high availability failover.
Key Ceremony & Policy Controls
Super custodian ceremonies, role based approvals, and policy engines that govern every key operation at scale.
Secure Enclave Provisioning
Provision keys to wallet programs, secure enclaves, and custody endpoints with full lifecycle visibility.
Nine capabilities, one stack
HSM management, MPC protocol, Fireblocks connectivity, and distributed share architecture, numbered for RFPs, security reviews, and integration planning.
HSM Cluster Management
Deploy, monitor, and scale HSM clusters across cloud and on premise environments with unified orchestration.
MPC Key Sharding
MPC protocol with threshold signing and distributed key shares, quorum attestation for institutional wallet programs.
Policy Engine & Approvals
Define key policies, approval workflows, and role based access for every custody operation.
Secure Enclave Provisioning
Provision and rotate keys into secure enclaves and wallet endpoints with hardware bound credentials.
Multi Tenant Isolation
Isolate wallet programs, issuers, and custodians with dedicated policy boundaries and audit scopes.
Audit & Compliance Logging
Immutable logs for key ceremonies, policy changes, and provisioning events, ready for regulators.
Fireblocks Integration
Connect SecurePayLedger custody workflows to Fireblocks institutional rails for treasury, transfer, and policy aligned operations.
Distributed Share Architecture
Key material split across HSM and MPC nodes with no single share sufficient to sign, reducing single point compromise risk.
MPC Protocol Operations
Distributed key generation, partial signing rounds, and coordinator flows engineered for institutional quorum policies.
Integrations & architecture
Integrated with Fireblocks. Built on MPC.
Connect to institutional custody rails, run threshold signing with MPC protocol controls, and distribute key shares across HSM boundaries without a single point of compromise.
Fireblocks connectivity
We integrate with Fireblocks so institutions can orchestrate custody, treasury, and wallet operations through a unified compliance first stack.
- Policy aligned transfers and treasury workflows
- Institutional connectivity without rebuilding custody cores
- Combines with super custodian HSM and MPC controls
Threshold signing & keygen
MPC protocol flows for distributed key generation and signing, designed for quorum based approvals and audit ready ceremonies.
- Partial signatures combined into valid on chain transactions
- Configurable quorum thresholds (for example 2 of 3)
- Ceremony logging for security and regulatory review
Distributed share architecture
Shares are generated, stored, and used across HSM boundaries so no single node holds a complete private key.
- HSM share storage with hardware backed isolation
- Share rotation and lifecycle controls at scale
- Resilient design against single point compromise
Key lifecycle
From policy to provisioning
Every key operation follows a governed path, policy definition, quorum ceremony, secure distribution, and lifecycle control at institutional scale.
- 01
Policy Definition
Define key policies, roles, and approval workflows.
- 02
Key Generation
HSM/MPC ceremony with quorum attestation.
- 03
Share distribution
Distributed shares provisioned across HSM and MPC nodes.
- 04
Lifecycle Control
Rotation, suspension, and revocation at scale.
MPC protocol
End-to-end crypto life cycle using MPC
From wallet creation to transaction finalization on Ethereum — every step governed by distributed key generation, HSM share storage, policy approvals, and threshold signing.
Wallet creation (MPC keygen)
Customer or institution requests a new wallet in the custody platform.
Distributed key generation (DKG)
MPC nodes jointly generate the key without any single party knowing the complete private key.
Shares created & stored
Shares are securely stored in HSMs. The blockchain address is created and ready for use.
Transaction approval
Transaction request passes risk, policy checks, and multi party approvals.
MPC signing
MPC nodes create partial signatures. The coordinator combines them into a valid signature.
Broadcast to Ethereum network
Signed transaction is broadcast to the Ethereum network and validated by nodes.
Transaction finalized
Transaction is included in a block, confirmed by the network, and recorded on chain.
Security with MPC
- No private key exposure
- Resistant to single point compromise
- Threshold security (for example 2-of-3)
- HSM backup & recovery
- Shares are distributed & protected
HSM infrastructure
Keys under institutional control
Super custodian HSM and MPC infrastructure for wallet programs that need hardware backed security without sacrificing operational velocity.
Hardware backed key custody
FIPS 140-2 validated HSMs, MPC protocol flows, and distributed share architecture for institutional grade key protection.
Super custodian ceremonies
Quorum based key generation and signing with full ceremony audit trails.
Policy at every layer
Role based approvals, rate limits, and policy engines across all key operations.
Wallet program provisioning
Secure enclave provisioning for exchange, custody, and tokenization wallet programs.
Why SecurePayLedger
Built for institutional scale
HSM and MPC infrastructure that custodians, exchanges, and wallet providers can deploy with confidence.
Bank grade key custody
Built for institutions that need qualified custody, HSM boundaries, and regulatory reporting.
Hardware backed security
Keys never leave HSM or MPC boundaries, policy controlled from ceremony to revocation.
Fireblocks ready connectivity
Integrate with Fireblocks custody rails while retaining super custodian policy and audit controls.
Open integration APIs
REST, PKCS#11, and webhook interfaces for custodians, exchanges, and wallet providers.
Cloud or on premise
Deploy in your cloud, ours, or dedicated on premise environments with HSM isolation.
Security by design
Hardware backed keys with full lifecycle visibility
FIPS validated HSMs, MPC quorum ceremonies, and audit ready reporting, engineered for super custodian operations.
