NexaVault — Institutional Custody

The Problem

Custody Is the Biggest Barrier to Institutional Adoption

Hedge funds, family offices, and institutional investors manage over $100 trillion in AUM. Yet less than 1% of these assets are in crypto — despite growing interest.

Why? Custody solutions are inadequate:

Traditional custodians (Coinbase, BitGo) have limited asset coverage
Self-custody is too risky (single private keys, no insurance)
Multi-sig wallets don't meet regulatory requirements
No SOC 2 / ISO 27001 certified options for DeFi protocols

NexaVault solves this with institutional-grade custody powered by MPC, comprehensive insurance, and full regulatory compliance.

Features

Built for Institutions

Military-grade security meets regulatory compliance.

Multi-sig Governance

Flexible M-of-N multi-signature policies. Customizable approval workflows for different transaction types and amounts.

MPC Technology

Multi-party computation eliminates single points of failure. Private keys never exist in one place — distributed across secure enclaves.

Cold Storage

95% of assets in air-gapped cold storage. Hot wallets auto-rebalance to maintain operational liquidity without sacrificing security.

Insurance Coverage

$100M insurance policy underwritten by Lloyd's of London. Coverage for theft, hacks, insider threats, and operational errors.

Compliance Built-In

SOC 2 Type II, ISO 27001, CCSS Level 3, GDPR, MiCA ready. Automated Travel Rule compliance for cross-border transactions.

Reporting Dashboard

Real-time portfolio tracking, transaction history, audit logs, and compliance reports. Export to CSV, PDF, or integrate via API.

API Access

RESTful API for programmatic access. Automate deposits, withdrawals, and balance queries. Webhooks for real-time events.

White-label Solution

Rebrand NexaVault with your logo and domain. Offer custody services to your clients under your brand.

Architecture

Zero Trust Security Model

1

HSM Key Management

All cryptographic operations execute inside FIPS 140-2 Level 3 hardware security modules. Keys are generated, stored, and used entirely within tamper-resistant hardware — never exported to software.

2

Air-gapped Signing

Cold storage transactions are signed offline on air-gapped servers in geographically distributed secure facilities. Multi-party approval required before any asset movement.

3

Geographic Distribution

Key shards distributed across 6 geographic zones (US East, US West, EU, Asia, South America, Australia). No single region can compromise custody.

4

Disaster Recovery

Automated failover and backup systems. Key recovery via Shamir Secret Sharing. RTO (Recovery Time Objective) < 4 hours, RPO (Recovery Point Objective) < 15 minutes.

Compliance

Meets Regulatory Standards Worldwide

SOC 2 Type II: Annual third-party audit of security, availability, processing integrity, confidentiality, and privacy controls.
ISO 27001: Information security management system (ISMS) certification.
CCSS Level 3: CryptoCurrency Security Standard — highest level of custodial security.
GDPR Compliant: Full compliance with EU data protection regulations.
MiCA Ready: Prepared for EU Markets in Crypto-Assets regulation (effective 2025).
Travel Rule Compliant: Automated VASP information exchange for cross-border transactions over $1,000.
