Core Services Offered by Gemini
Digital Asset Exchange
Gemini operates a 24/7 digital asset marketplace powered by a centralized limit order book that follows price-time priority execution. This ensures fair and transparent trading for all participants. The exchange supports major cryptocurrencies such as BTC, ETH, and various stablecoins, enabling users to trade with confidence.
Unlike some platforms, Gemini is a full-reserve exchange—meaning all trades must be fully funded. Margin trading or leveraged positions are not offered, reducing systemic risk and protecting users from unexpected liquidations. Every open order reduces available balance until executed or canceled, ensuring account integrity.
Block Trading
For high-volume traders and institutions, Gemini offers Block Trading™, an electronic facility that enables large trades outside the continuous order book. This minimizes market impact and enhances liquidity execution during significant transactions, making it ideal for hedge funds, ETFs, and asset managers.
Auction Mechanism
Gemini conducts daily auctions for select trading pairs—including weekends and holidays—to boost price discovery and market efficiency. These periodic auctions help align supply and demand, especially during low-liquidity periods, contributing to more stable and reliable pricing.
Institutional-Grade Custody Solutions
As a regulated New York trust company, Gemini acts as a fiduciary custodian under Article X of the New York Banking Law. It provides two primary custody models:
- Deposit Accounts: Default for retail users, where assets are held securely with enterprise-grade protection.
- Segregated Custody Accounts: Designed for institutions such as mutual funds or ETFs that require legally isolated holdings. In this model, clients retain full ownership while benefiting from Gemini’s compliance framework and insurance-backed storage.
This dual approach ensures flexibility without compromising on regulatory compliance or security standards.
Security Architecture: Built for Trust
Gemini’s security model is built on three foundational principles:
- Defense in depth against external threats
- Prevention of human error
- Protection against insider misuse
These principles guide every technical and operational decision across the platform.
Cold Storage & Key Management
Over 95% of customer digital assets are stored in offline air-gapped cold storage, minimizing exposure to cyberattacks. Within this system, Gemini employs a two-tier structure: Cold and Cryogenic™ storage layers, enhancing redundancy and physical security.
All private keys are generated, stored, and managed within Hardware Security Modules (HSMs) certified to FIPS PUB 140-2 Level 3 or higher standards. These HSMs are hosted in geographically dispersed, access-controlled facilities with continuous monitoring.
Multi-signature technology (Multisig) eliminates single points of failure by requiring multiple approvals for any fund movement. Additionally, hardware diversity across HSM vendors mitigates supply chain risks.

Hot Wallet Security
The small portion of assets needed for real-time transactions resides in hot wallets, hosted on Amazon Web Services (AWS). AWS provides strong physical security and internal controls.
Access to production systems follows the principle of least privilege:
- Role-based permissions limit employee access
- Administrative access requires multi-factor authentication (MFA)
- Hot wallet key management is rooted in AWS CloudHSM, using FIPS 140-2 Level 2 validated hardware
All fund transfers require coordinated actions from multiple authorized personnel—no single individual can initiate a withdrawal.
Financial and Data Security
Customer fiat funds (USD) are held in aggregate accounts at FDIC-insured U.S. banks. While these accounts are not individually insured, they are legally segregated from Gemini’s corporate funds, ensuring client asset protection.
User data is protected both in transit and at rest:
- All communications use TLS encryption (HTTPS)
- Passwords are hashed using modern cryptographic standards
- Content Security Policy (CSP) and HTTP Strict Transport Security (HSTS) protect against web-based attacks
- Rate limiting prevents brute-force login attempts
Internal systems are isolated from public internet access, and third-party data sharing is strictly prohibited. Gemini does not share customer information or TLS private keys with any vendor.
Regulatory Compliance and Operational Integrity
As a New York trust company, Gemini adheres to stringent capital reserve requirements, cybersecurity protocols, and anti-money laundering (AML) standards set by the NYSDFS. Its regulatory status gives users confidence that operations meet banking-level compliance benchmarks.
Employees undergo comprehensive background checks—criminal and credit—before onboarding and throughout employment. Remote access is secured via public-key authentication only; passwords, OTPs, or other stealable credentials are disallowed.
Even Gemini’s executives—including CEO Tyler Winklevoss and President Cameron Winklevoss—cannot unilaterally move funds from cold storage. Multi-party authorization is mandatory for all critical operations.
Email communications are carefully controlled. Official messages contain only links to public blog posts or product updates. Domain policies signal major email providers (e.g., Gmail, Yahoo) to reject spoofed messages. Users are encouraged to verify suspicious emails by contacting [email protected] or forwarding them to [email protected].
