Bitfex is a cutting-edge crypto derivatives exchange, designed to serve the growing global demand for sophisticated crypto trading tools. Registered in Seychelles, Bitfex offers traders:

• A broad array of crypto derivatives products, from perpetual contracts to leverage instruments.
• An exceptionally secure, intuitive interface that makes both casual and professional trading seamless.
• Robust infrastructure to support high-frequency trades and instant order execution.

Bitfex set out to build a world-class mobile experience, ensuring traders could access their portfolios and execute trades on the go without sacrificing speed or security. They chose ThoughtWin IT Solutions for our deep expertise in building high-performance, secure mobile apps on iOS and Android.

• Native iOS & Android Apps: Built tailored, high-performance apps for both platforms using Swift (iOS) and Kotlin (Android), ensuring maximum native speed and fluid UI interactions.
• Secure Authentication & Session Management: Implemented biometric authentication (Face ID, Touch ID) plus robust session tokens with secure refresh, balancing trader convenience with exchange-grade security.
• Real-time Trading Data & Order Books: Leveraged WebSocket connections to deliver live market feeds, order book updates, and user portfolio changes without polling delays.
• Advanced Trading Tools on Mobile: Developed intuitive modules for setting take-profit/stop-loss, configuring leverage, and executing complex order types — all optimized for small-screen ergonomics.
• Notification & Alert System: Created a flexible system for traders to set custom price or portfolio alerts, delivered via push notifications with deep links straight into the relevant trading pair.

• Fully native vs hybrid: Chose to build fully native apps over cross-platform options to guarantee the lowest latency on chart rendering and trade execution — critical in volatile crypto markets.
• Biometric-first security: Prioritized trader trust and ease by building biometric re-auth for sensitive actions, reducing risk of stolen credential misuse.
• Separate WebSocket data streams: Isolated different feeds (market tickers, order book, personal P&L) to independently manage reconnections and prioritize critical updates under network stress.
• Minimal local data footprint: Avoided unnecessary on-device data storage beyond encrypted session tokens, mitigating security concerns.

Crafted a streamlined mobile UI that balances power with simplicity:

• Interactive candlestick charts with pinch-to-zoom and crosshair tracking.
• Slide-to-set leverage and intuitive toggle switches for advanced order parameters.
• Quick-access tabs to switch between markets, open positions, order history, and wallet balances.

Designed light and dark modes to support long trading sessions without eye fatigue. Included a flexible alert manager so traders can easily set threshold or percentage-change notifications for any listed asset.

• Enabled Bitfex to launch a truly mobile-first derivatives platform, broadening its reach to traders who demand 24/7 access to markets.
• Increased active daily usage — with the majority of trades now executed via mobile apps thanks to the high-speed, trader-focused UX.
• Positioned Bitfex as a secure, professional-grade alternative in a crowded crypto exchange market, attracting higher-volume clients.
