The digital asset trading landscape is continuously evolving, and platform performance, reliability, and user cost-efficiency are more important than ever. To meet growing demand and ensure a seamless trading experience, OKX has implemented a strategic infrastructure upgrade—specifically targeting its contract trading system. This article covers the details of the Contract 2.0 architecture upgrade, including service interruptions, performance enhancements, and upcoming trading fee reductions designed to benefit all users.
Why the Contract 2.0 Upgrade Was Necessary
As cryptocurrency markets grow in volume and complexity, legacy systems often struggle to keep pace. High-frequency trading, volatile price swings, and increasing user demand require robust backend architecture capable of handling massive data throughput with minimal latency.
OKX recognized the need for a scalable, high-performance contract trading engine. The Contract 2.0 upgrade was launched to address these challenges by rebuilding the core database infrastructure. This foundational change enables faster order matching, improved API responsiveness, and greater system stability during peak market activity.

Scheduled Maintenance and Service Interruption
To carry out the upgrade, OKX conducted a planned maintenance window on September 5, 2018, from 20:00 to 20:30 HKT. However, due to intense market volatility, the actual upgrade was temporarily postponed to 21:30 HKT, then initiated at 21:41 HKT, completing successfully by 22:05 HKT.
During this period:
- All contract trading functions were temporarily suspended.
- Users could not place new orders via web or API.
- Actions such as margin adjustments, position modifications, or liquidation management were unavailable.
This brief downtime was essential to ensure data integrity and prevent errors during the migration process.
Key Notes for Traders:
- Non-contract services—including spot trading and fiat transactions—remained fully operational.
- Users were advised to adjust positions or add margin before the maintenance window to avoid potential liquidation risks.
- Real-time updates were provided through official channels, with post-upgrade confirmation once systems were restored.
Performance Improvements After the Upgrade
The Contract 2.0 architecture overhaul wasn't just about fixing bottlenecks—it was about future-proofing the platform.
Enhanced Trading Engine
The upgraded database now supports:
- Faster order matching speeds, reducing latency for both retail and institutional traders.
- Higher throughput for API-driven strategies, accommodating algorithmic and bot-based trading at scale.
- Improved resilience during flash crashes or rapid price movements.
Expanded API Capabilities
One of the most anticipated outcomes of the upgrade is the relaxation of API rate limits. Traders who rely on automated systems will benefit from increased request allowances, allowing for more frequent data polling and order execution without throttling.
This positions OKX as a preferred platform for quantitative traders and high-frequency trading (HFT) participants seeking low-latency access and stable connectivity.

Trading Fee Reduction to Boost Liquidity
In line with its commitment to user-centric improvements, OKX announced a reduction in trading fees across both contract and spot markets, effective September 7, 2018, at 00:00 HKT.
Lower fees serve two critical purposes:
- Reduce trading costs for individual and professional traders.
- Improve market liquidity, encouraging more participation and tighter bid-ask spreads.
While the original fee schedule table has been removed per content guidelines, the revised structure favored makers and high-volume traders, with tiered discounts based on 30-day trading volume and OKB holdings—a move that aligns user incentives with long-term platform growth.
This fee optimization reflects a broader industry trend where exchanges compete not only on features but also on cost efficiency and transparency.
Upcoming System Enhancements
The September 5 upgrade was just the first of four planned improvements scheduled throughout early September 2018. These phased upgrades aim to comprehensively modernize:
- Data processing pipelines
- Risk management modules
- Settlement mechanisms
- User interface responsiveness
Each phase focuses on increasing system robustness while minimizing disruption. By rolling out changes incrementally, OKX ensures thorough testing and rapid rollback capabilities if needed—prioritizing security and user trust above all.
Frequently Asked Questions (FAQ)
Q: Why was the database upgrade delayed on September 5?
A: Due to heightened market volatility, OKX postponed the maintenance window to avoid executing critical system changes during unstable price conditions. User fund safety and data consistency are top priorities.
Q: Were my funds at risk during the upgrade?
A: No. All user assets remained secure throughout the maintenance period. The suspension only affected trading functionality—not wallet deposits, withdrawals, or account balances.
Q: How do lower trading fees benefit me?
A: Reduced fees directly lower your cost per trade, which can significantly improve net returns—especially for active traders. It also encourages tighter spreads, improving execution quality.
