Key custody built on hardware and quorum

Hardware security modules and MPC work together so no single person, node, or share can move assets on its own.

  • 01

    HSM / MPC Infrastructure

    Clustered HSM and MPC key infrastructure with hardware attestation, quorum policies, and high-availability failover.

  • 02

    Key Ceremony & Policy Controls

    Super custodian ceremonies, role-based approvals, and policy engines that govern every key operation.

  • 03

    Secure Enclave Provisioning

    Provision keys to wallet programs, secure enclaves, and custody endpoints with full lifecycle visibility.

Everything a super custodian needs to run keys

Cluster management, sharding, policy, provisioning, and audit in one platform, deployed in your cloud, ours, or on premises.

  • 01

    HSM Cluster Management

    Deploy, monitor, and scale HSM clusters across cloud and on-premises environments with unified orchestration.

  • 02

    MPC Key Sharding

    MPC protocol with threshold signing and distributed key shares, quorum attestation for institutional wallet programs.

  • 03

    Policy Engine & Approvals

    Define key policies, approval workflows, and role-based access for every custody operation.

  • 04

    Secure Enclave Provisioning

    Provision and rotate keys into secure enclaves and wallet endpoints with hardware-bound credentials.

  • 05

    Multi-Tenant Isolation

    Isolate wallet programs, issuers, and custodians with dedicated policy boundaries and audit scopes.

  • 06

    Audit & Compliance Logging

    Immutable logs for key ceremonies, policy changes, and provisioning events, ready for regulators.

  • 07

    Fireblocks Integration

    Connect SecurePayLedger custody workflows to Fireblocks institutional rails for treasury, transfer, and policy-aligned operations.

  • 08

    Distributed Share Architecture

    Key material split across HSM and MPC nodes with no single share sufficient to sign, reducing single-point compromise risk.

  • 09

    MPC Protocol Operations

    Distributed key generation, partial signing rounds, and coordinator flows engineered for institutional quorum policies.

  • HSM + MPC
  • PKCS#11
  • Quorum approvals
  • Fireblocks integration
  • Distributed shares
  • End-to-end auditability

Integrations and architecture

Connect to the custody rails you already use while keeping super custodian policy and audit controls.

  • Integration

    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
  • MPC protocol

    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
  • Architecture

    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
    • Resilient design against single-point compromise

End-to-end crypto lifecycle using MPC

From wallet creation to a finalised transaction on Ethereum, the private key is never assembled in one place.

  1. 01

    Wallet creation (MPC keygen)

    Customer or institution requests a new wallet in the custody platform.

  2. 02

    Distributed key generation (DKG)

    MPC nodes jointly generate the key without any single party knowing the complete private key.

  3. 03

    Shares created & stored

    Shares are securely stored in HSMs. The blockchain address is created and ready for use.

  4. 04

    Transaction approval

    Transaction request passes risk, policy checks, and multi party approvals.

  5. 05

    MPC signing

    MPC nodes create partial signatures. The coordinator combines them into a valid signature.

  6. 06

    Broadcast to Ethereum network

    Signed transaction is broadcast to the Ethereum network and validated by nodes.

  7. 07

    Transaction finalized

    Transaction is included in a block, confirmed by the network, and recorded on-chain.

  8. 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

Key lifecycle under policy control

Every key follows the same governed path, from the first policy to rotation and revocation.

  1. 01

    Policy Definition

    Define key policies, roles, and approval workflows.

  2. 02

    Key Generation

    HSM/MPC ceremony with quorum attestation.

  3. 03

    Share distribution

    Distributed shares provisioned across HSM and MPC nodes.

  4. 04

    Lifecycle Control

    Rotation, suspension, and revocation.

  • Hardware-backed key custody

    Hardware security modules, 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 institutions choose SecurePayLedger

Bank-grade controls from the first ceremony, with the integrations your custody stack already depends on.

  • 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-premises

    Deploy in your cloud, ours, or dedicated on-premises environments with HSM isolation.
