Cryptocurrency trading has evolved into a multi-billion-dollar global market, attracting both novice investors and seasoned traders. If you're exploring reliable platforms to enter this space, you may have come across GDAX—a name once widely recognized in the crypto community. While the platform has since been rebranded, understanding its foundation offers valuable insight into one of the industry’s most trusted trading environments.
In this comprehensive review, we’ll explore what GDAX was, how it functioned, and why it transitioned into Coinbase Pro. You'll learn about its security measures, fee structure, supported cryptocurrencies, and user experience—all critical factors when choosing a crypto exchange.
Whether you're evaluating past platforms for research or preparing to use Coinbase Pro today, this guide delivers actionable insights to help you trade confidently.
What Was GDAX? (Now Coinbase Pro)
GDAX, short for Global Digital Asset Exchange, was launched in 2016 as a professional-grade trading platform by the same team behind Coinbase. Designed for more advanced users, GDAX allowed real-time buying, selling, and trading of digital assets with powerful tools not available on the standard Coinbase interface.
Unlike basic exchanges that only support simple purchases, GDAX functioned as a full-fledged marketplace where traders could place limit orders, stop-loss orders, and market-making trades—features essential for active crypto investors.
One major advantage: if you already had a Coinbase account, you automatically had access to GDAX using the same login credentials. This seamless integration made it easy for users to move funds between platforms instantly and at no cost.
At its peak in late 2017, GDAX reported single-day trading volumes exceeding **$650 million**, reflecting its popularity during the crypto boom. By mid-2018, daily volume averaged around $100 million, solidifying its position among top-tier exchanges.

GDAX Is Now Coinbase Pro
In May 2018, GDAX officially rebranded to Coinbase Pro, marking an evolution in user experience and functionality. While the core services remained unchanged, the new platform introduced several improvements:
- A cleaner, more intuitive interface
- Enhanced charting tools with expanded timeframes
- Streamlined deposit and withdrawal processes
- Better portfolio tracking and balance visibility
Despite the name change, all existing GDAX accounts were migrated seamlessly to Coinbase Pro. Users found the updated design easier to navigate, especially when analyzing price trends or managing multiple trades.
Additionally, Coinbase acquired Paradex, a decentralized exchange built on Ethereum, to enhance support for ERC-20 tokens—cryptocurrencies built on the Ethereum blockchain. This move signaled Coinbase’s long-term commitment to expanding asset availability while maintaining compliance with U.S. financial regulations.
For clarity, this article refers to the platform as "GDAX" where relevant to historical context, but note that GDAX no longer exists as a separate entity—it is now fully integrated into Coinbase Pro.
Supported Payment Methods and Fee Structure
A key factor in choosing any exchange is how easily you can fund your account and how much it costs. GDAX supported several real-world payment methods, though availability varied by region.
Deposit Options
- U.S. Bank Transfers (ACH): 1.49% fee
- Wire Transfers (U.S.): $10 deposit fee, $25 withdrawal fee
- SEPA (Europe): Free deposits; €0.15 withdrawal fee
- Canada, Singapore, Australia: Deposits allowed in fiat, but withdrawals restricted—users must convert to crypto before transferring out
You could also transfer funds directly from your Coinbase balance to GDAX instantly and free of charge.
Credit and debit card deposits were not supported directly on GDAX, but could be made through Coinbase at a 3.99% fee before transferring funds over.
Cryptocurrency Deposits
Depositing crypto to GDAX incurred no fees from the platform itself, though standard blockchain network fees applied. Withdrawals followed the same model—free on GDAX’s end, with only network costs passed on.
Trading Fees: Maker vs. Taker Model
GDAX used a competitive tiered fee system based on trading volume and order type:
| Order Type | Fee (Up to $10M/month) | High Volume (> $100M/month) |
|---|---|---|
| Market Maker | 0.00% | 0.10% |
| Market Taker | 0.30% | 0.10% |
- Market Makers place limit orders below or above current market price, adding liquidity.
- Market Takers execute trades immediately at existing prices, removing liquidity.
This model incentivized users to contribute to market stability while keeping costs low—especially beneficial for high-frequency traders.

Available Cryptocurrencies on GDAX
One of GDAX’s main limitations was its limited selection of tradable coins. At the time of its operation, only four cryptocurrencies were supported:
- Bitcoin (BTC)
- Ethereum (ETH)
- Litecoin (LTC)
- Bitcoin Cash (BCH)
These could be traded against major fiat currencies like USD and EUR—an advantage over many peer platforms at the time.
There were plans to expand the list, including adding Ethereum Classic (ETC) later in 2018. However, due to strict regulatory oversight in the U.S., Coinbase moved cautiously in listing new assets.
This limited selection made GDAX less appealing for traders seeking exposure to altcoins like Ripple (XRP), Cardano (ADA), or Binance Coin (BNB)—many of which saw massive price movements during that period.
For those wanting broader access, exchanges like Binance offered hundreds of trading pairs—a stark contrast to GDAX’s minimalist approach.
Account Registration and Verification Process
Signing up for GDAX was straightforward—especially if you already had a Coinbase account. For new users, the registration process followed strict Know Your Customer (KYC) protocols:
- Provide personal details: name, address, nationality
- Upload government-issued ID (passport or driver’s license)
- Wait for automated verification (typically under 10 minutes)
Due to U.S.-based operations, not all countries were eligible to join. Anonymous trading was not permitted.
Users wishing to withdraw more than $10,000 per day faced additional verification steps, such as phone confirmation or proof of address.
While some viewed these measures as restrictive, they contributed significantly to the platform’s reputation for security and regulatory compliance.
Customer Support and Responsiveness
GDAX offered reliable customer support through multiple channels:
- Phone support: Available Monday–Friday, 8 AM–5 PM Pacific Time
- Email: 24/7 submission with prompt responses
- Social media: Active presence on Twitter (though users were advised against sharing sensitive data publicly)
The main drawback? No live chat option, which delayed resolution for urgent issues outside business hours.
Still, overall response times were fast compared to many competitors at the time—especially given the volume of users served.
Is GDAX Safe? Security Features Explained
Security was a top priority for GDAX. As part of the Coinbase ecosystem, it inherited robust protection mechanisms:
- 98% of customer funds stored in cold storage (offline wallets)
- Online reserves are insured against breaches
- Optional two-factor authentication (2FA) via mobile apps
- Vault protection: Withdrawals delayed by 48 hours unless canceled
- Multi-signature approvals: Required secondary authorization for large withdrawals
Additionally, U.S.-based customers holding USD balances benefited from an FDIC-insured custodial agreement, protecting up to $250,000 per account—though this did not cover cryptocurrency holdings.
Despite these precautions, a notable incident occurred on June 21, 2018: a large sell order caused Ethereum’s price on GDAX to briefly crash from $319 to $0.10. This triggered automatic stop-loss orders and raised concerns about market manipulation risks in low-liquidity scenarios.
However, aside from this anomaly, GDAX maintained a clean record with no major hacks or fund losses reported.
Who Should Use Coinbase Pro (Formerly GDAX)?
GDAX was best suited for:
- Intermediate to advanced traders seeking real-time order execution
- U.S.-based investors prioritizing regulatory compliance and security
- Users already on Coinbase looking to upgrade to professional tools
Its clean interface and tight integration with Coinbase made it ideal for those transitioning from beginner to active trading—though limited coin options deterred diversification-focused investors.
