About This Project

ChainScore Labs partnered with Telos Foundation to design and engineer TelosX—a full-featured centralized exchange built to serve the Telos ecosystem. We architected the complete trading infrastructure: order matching, wallet management, professional charting, KYC/AML compliance, and a responsive interface that works across desktop and mobile. The result is an exchange that balances institutional-grade performance with the accessibility needed to onboard the next wave of crypto users.

CHALLENGE

The Challenge

Telos Foundation needed a centralized exchange to serve their ecosystem—a platform that could compete with established exchanges while integrating natively with Telos blockchain assets. The challenge was building something that felt familiar to traders coming from Binance or Coinbase, while maintaining the technical standards required for a financial platform: sub-second order execution, robust security, and regulatory compliance across multiple jurisdictions. Most exchange projects fail because teams underestimate the complexity. Order matching alone requires handling race conditions, partial fills, and price-time priority correctly. Add custodial wallets, KYC workflows, fiat on-ramps, and real-time market data—and you have a system where any weak link compromises the whole.

APPROACH

Our Approach

We started with the trading engine—the core of any exchange. Rather than adapt existing solutions, we built a custom matching engine optimized for the specific requirements of TelosX: support for multiple order types, integration with external liquidity, and the ability to handle traffic spikes during volatile markets.

Order Matching First: Built and stress-tested the matching engine before building any UI. This ensured the foundation was solid before adding complexity.
Security by Design: Cold wallet architecture, multi-signature withdrawals, and rate limiting baked in from day one—not bolted on later.
Progressive Enhancement: Designed the interface to work well for basic trading, then layered on professional features without overwhelming new users.

TRADING-ENGINE

Trading Engine

The matching engine is the most critical component of any exchange. Ours processes orders in strict price-time priority, handles partial fills correctly, and maintains consistency even under high load. We implemented limit, market, stop-loss, and OCO order types—each with its own edge cases and failure modes that needed careful handling.

Price-Time Priority: Orders are matched fairly, with earlier orders at the same price level always executed first.
Atomic Operations: Balance updates, order fills, and trade records are processed atomically. No partial states, no race conditions.
Horizontal Scaling: Different trading pairs can be processed independently, allowing the system to scale with demand.

WALLET-SYSTEM

Wallet Infrastructure

Custodial done right

Custodial wallet systems are where most exchange hacks happen. We implemented a tiered architecture: hot wallets hold only what's needed for immediate withdrawals, with the majority of assets in cold storage requiring multi-signature authorization. Deposit detection, withdrawal processing, and balance reconciliation all run as independent services with their own monitoring and alerting.

Cold Storage: The majority of assets are held offline, requiring multiple authorized signatures to move.
Withdrawal Limits: Configurable limits and delays for large withdrawals, with manual review for suspicious patterns.
Real-time Reconciliation: Automated balance checks between database records and on-chain state, with alerts for any discrepancy.

PROFESSIONAL-TRADING

Professional Trading Interface

Tools traders actually use

Professional traders need more than basic buy/sell functionality. We integrated TradingView charts with the full suite of technical indicators, built a customizable workspace layout, and implemented keyboard shortcuts for rapid order entry. The interface stays responsive even when displaying real-time data for hundreds of assets.

TradingView Integration: Full charting suite with 50+ indicators, drawing tools, and multi-timeframe analysis.
Order Entry: Quick order forms with limit, market, stop-loss, and OCO support. Keyboard shortcuts for power users.
Real-time Orderbook: WebSocket-powered orderbook and trade feed with sub-second updates.

MOBILE

Mobile Experience

We designed the mobile interface from scratch rather than forcing the desktop experience onto smaller screens. The result is a trading experience that feels native on mobile—with touch-optimized controls, streamlined navigation, and the same real-time data feeds as the desktop version.

Touch-Optimized: Swipe gestures, tap targets, and layouts designed specifically for mobile interaction.
Full Feature Parity: Every trading feature available on desktop works on mobile.
Push Notifications: Price alerts, order fills, and security notifications delivered in real-time.

COMPLIANCE

Compliance & Security

Operating a centralized exchange means meeting regulatory requirements across multiple jurisdictions. We integrated KYC/AML services with an onboarding flow that collects required information progressively—basic features available immediately, with additional verification unlocking higher limits. Security audits were conducted at each major milestone, with penetration testing before launch.

Progressive KYC: Users can start trading immediately with basic verification. Higher limits require additional documentation.
AML Monitoring: Transaction monitoring with automated flagging of suspicious patterns for compliance review.
Security Audits: Third-party security assessments at each major development milestone.

ONBOARDING

User Onboarding

Exchange onboarding is often frustrating—long forms, unclear requirements, and confusing verification steps. We streamlined the process to get users trading as quickly as possible while still meeting compliance requirements.

Minimal Initial Steps: Email, password, and basic verification is enough to start exploring the platform.
Guided Verification: Clear instructions and real-time feedback during document submission.
Contextual Help: Tooltips and guides appear where users need them, not in a separate help section.
