Gemini

Gemini is a regulated cryptocurrency exchange and custodian that offers retail traders, institutional clients, and developers a single platform for spot trading, perpetual contracts, staking, custody, prediction markets, and crypto-linked credit cards. Founded in 2014 by Cameron and Tyler Winklevoss and launched to the public in 2015, Gemini operates as a New York limited-purpose trust company chartered by the New York State Department of Financial Services (NYDFS), making it one of the most heavily regulated cryptocurrency platforms in the United States.

Background and Regulatory Standing

Cameron and Tyler Winklevoss co-founded Gemini after their high-profile legal settlement with Mark Zuckerberg over the origins of Facebook, channeling a portion of those proceeds into building a crypto exchange designed around regulatory compliance from day one. Both brothers hold Harvard economics degrees and MBA degrees from Oxford, and they represented the United States in rowing at the 2008 Beijing Olympic Games.

As an NYDFS trust company, Gemini is legally structured as a fiduciary, meaning it must keep client assets segregated from corporate funds and maintain capital reserves that meet regulatory minimums. Gemini was the first cryptocurrency exchange to complete SOC 1 Type 2 and SOC 2 Type 2 audits, certifications it has maintained alongside ISO 27001 compliance. These credentials are a primary reason institutional asset managers, hedge funds, and ETF issuers choose Gemini's custody arm over less-regulated alternatives.

In September 2025, Gemini went public on NASDAQ under the ticker GEMI through a $425 million IPO, with shares gaining more than 14% on their debut day.

Core Products and Platform

Gemini's retail-facing exchange supports spot trading across more than 75 tokens. The ActiveTrader 2.0 interface, relaunched in August 2026, provides a professional-grade trading environment with deep order books, advanced charting, and API or FIX protocol connectivity for algorithmic strategies. The platform also offers perpetual contracts and margin trading for traders seeking leveraged exposure without holding underlying assets.

On the consumer side, Gemini operates a branded credit card lineup with crypto cashback rewards. The original card paid rewards in Bitcoin; subsequent editions added XRP and, most recently, Solana. The exchange also issues the Gemini Dollar (GUSD), a US dollar-pegged stablecoin.

A newer addition is Gemini's prediction markets product, which uses Grok AI to deliver personalized outcome probabilities across categories including sports, crypto, commodities, economics, and politics. Traders take yes/no positions and receive a $1.00 per-contract payout for correct calls.

In August 2026, Gemini expanded further by introducing 24/5 stock trading with limit orders, adding equities to a platform that already covered crypto derivatives, staking, and prediction markets. The company describes its current positioning as "one platform for predicting, investing, and earning."

Solana Integration

Gemini's Solana support began in February 2022, when the exchange listed SOL for spot trading on its API, FIX, and ActiveTrader interfaces across USD, GBP, EUR, CAD, AUD, HKD, and SGD pairs. Users could also take custody of SOL in Gemini's exchange wallet from launch.

The relationship with Solana deepened substantially through 2025. In early September 2025, Gemini listed three Solana-native protocol tokens: Jupiter (JUP), the leading Solana DEX aggregator; Kamino (KMNO), the Solana lending and liquidity protocol; and Drift Protocol (DRIFT), the Solana perpetuals exchange. These additions positioned Gemini as a regulated on-ramp specifically for Solana's DeFi ecosystem rather than just for SOL itself.

On October 14, 2025, Gemini enabled USDT and USDC deposits and withdrawals on the Solana network, allowing users to move stablecoins via Solana's rails for faster settlement and lower fees compared to Ethereum-based transfers.

Six days later, on October 20, 2025, Gemini launched the Solana Credit Card. The card earns SOL rewards at category-based rates: 4% back on gas, EV charging, and rideshare; 3% on dining; 2% on groceries; and 1% on all other purchases. An optional auto-staking feature deposits earned SOL directly into Gemini's staking program, which offered yields of up to 6.77% APY at launch. SOL staking rewards can be withdrawn at any time, though settlement takes between a few hours and several days.

Institutional Custody and the VanEck Solana ETF

Gemini's most significant Solana footprint is in institutional custody. On June 13, 2025, Gemini Trust Company, LLC entered into a Custodial Services Agreement with the VanEck Solana ETF, serving as the primary SOL custodian for the trust. This arrangement places Gemini at the center of regulated institutional exposure to Solana, handling the on-chain custody and settlement infrastructure for an SEC-registered investment vehicle. VanEck holds a minority stake of less than 1% in Gemini Trust Company as a result of this relationship.

The VanEck mandate reflects Gemini's broader institutional custody business, which serves asset managers and corporations that require SOC-certified infrastructure and regulatory transparency. The custody division also supports an electronic OTC desk for large-block trades that need to clear without moving the public order book.

API and Developer Access

Gemini's REST API exposes the full range of platform functionality: order creation and cancellation, historical and real-time market data, derivatives account management, fund transfers and withdrawals, margin position monitoring, prediction market contracts with WebSocket streaming, and OAuth-based authentication for subaccount management. Detailed documentation is available at developer.gemini.com.

Ecosystem Position

Gemini occupies a distinct niche in the Solana ecosystem: it is one of the few NYDFS-regulated venues that lists Solana-native DeFi tokens (JUP, KMNO, DRIFT), supports Solana-network stablecoin deposits, provides institutional SOL custody for registered investment vehicles, and offers a consumer credit card that auto-stakes SOL rewards. For users who want regulated, audited infrastructure — whether for large custody mandates or for earning staking yield on everyday spending — Gemini is among the most integrated compliant gateways into the Solana network.
