Architecture Overview
OrangeBit is designed as a hybrid on-chain/off-chain trading infrastructure, combining the transparency and security of decentralized finance with the speed and efficiency of centralized systems. The architecture is modular, ensuring scalability, reliability, and interoperability across multiple blockchain networks.
1. Access Layer (Web / Mobile / API)
The Access Layer serves as the primary interface between users and the OrangeBit platform.
Supports Web, Mobile, and API endpoints, enabling seamless integration with third-party services and trading bots.
Fully compatible with popular wallets such as WalletConnect, MetaMask, Coinbase Wallet, OKX Wallet, among others.
Users initiate trade requests through their wallets; all transactions are cryptographically signed and transmitted securely to the platform gateway or blockchain nodes.
The layer supports high concurrency connections while ensuring minimal latency in user interactions.
2. Matching Layer (Off-Chain)
The Matching Layer is responsible for real-time order processing with institutional-grade performance:
Powered by a high-performance matching engine utilizing multi-threaded and partitioned matching for efficient handling of limit, market, IOC (Immediate or Cancel), and FOK (Fill or Kill) orders.
Implements memory-optimized data structures, including price-time priority queues and fine-grained locking mechanisms, achieving ultra-low latency execution.
Fully horizontally scalable, enabling sharding by trading pair to handle high-frequency trading scenarios without compromising throughput.
Provides real-time order book snapshots to downstream layers and clients, ensuring consistent market state visibility.
3. Liquidity Aggregation Layer
The Liquidity Aggregation Layer ensures optimal depth and minimal slippage across trading pairs:
Aggregates liquidity from on-chain AMMs, partnered market makers (LPs), and external CEX or liquidity APIs, creating a unified liquidity pool.
Implements a smart routing engine that performs slippage estimation, dynamic order splitting, and optimal path selection, delivering the best execution prices for traders.
Supports cross-chain asset routing, allowing seamless trading across EVM-compatible chains, Solana, Aptos, and others.
Dynamically adjusts liquidity allocation based on market volatility, order flow, and platform-wide risk metrics.
4. Settlement Layer (On-Chain / Multi-Signature Custody)
OrangeBit ensures the security and auditability of user funds via the Settlement Layer:
Users’ assets are securely held either in their own wallets or multi-signature custody contracts managed by the platform.
Supports two settlement models:
Fully On-Chain Settlement: All matching results are ultimately cleared on-chain for maximum transparency.
Hybrid Settlement: Orders are matched off-chain for speed, while the resulting fund movements are settled on-chain or via multi-signature contracts for security and accountability.
Settlement logic is smart contract-driven, ensuring that all trades are atomic, verifiable, and resistant to tampering.
5. Risk Control & Liquidation Layer
The platform incorporates an AI-enhanced risk control system to protect both users and liquidity providers:
Supports real-time margin calculation with both isolated and cross-margin models.
Automates forced liquidation logic to maintain solvency and minimize systemic risk.
Risk engine provides simulation backtesting and real-time stress testing, evaluating exposure under extreme market conditions.
Detects anomalous trading patterns, front-running attempts, and potential market manipulation.
6. Monitoring & Auditing Layer
OrangeBit maintains continuous monitoring and transparent auditing capabilities:
Tracks latency, matching success rate, fund flows, and abnormal activity across the platform.
Key events, such as trade settlements, liquidations, and protocol upgrades, are logged on-chain for provable auditability.
Multi-tier logging ensures granular visibility while maintaining operational efficiency.
7. Governance & Token Layer
The governance layer ensures community-driven evolution and ecosystem sustainability:
The platform token $ORANGE (ERC-20 or cross-chain equivalent) enables:
Staking for participation in governance.
Voting on protocol parameters, upgrades, and treasury usage.
Buyback and reward mechanisms for long-term ecosystem health.
Governance mechanisms are transparent, auditable, and enforceable on-chain, gradually transitioning protocol control to the community.
8. Future Extensions
Subsequent sections of the whitepaper will provide:
Architecture pseudocode and workflow diagrams.
Smart contract interfaces and APIs.
Performance targets for matching engine throughput and latency metrics.
Integration examples with cross-chain routing and multi-chain settlements.
This modular design ensures OrangeBit can scale to handle high-frequency trading, aggregate deep liquidity across chains, enforce robust risk controls, and maintain transparent governance, while providing a CEX-grade trading experience with DEX-level security.
