Nexus Composer
The Nexus Composer functions as the protocol's intelligent coordination backbone, orchestrating complex multi-party transactions while maintaining complete transparency and user sovereignty. The Composer's architecture enables sophisticated optimization and routing without ever taking custody of user funds or compromising transaction security.
Advanced UTXO Management
The Composer maintains comprehensive state tracking across the entire protocol ecosystem, enabling optimal transaction construction and conflict prevention.
Real-Time State Coordination:
Continuous monitoring of approximately 50,000+ UTXOs across active ecosystem participants
Sub-second state updates incorporating mempool changes and block confirmations
Predictive availability modeling for optimal transaction construction timing
Advanced conflict detection and resolution preventing double-spend scenarios
Optimization Strategies:
Intelligent UTXO selection algorithms minimizing transaction fees and confirmation latency
Proactive UTXO consolidation and fragmentation management
Emergency fallback mechanisms during network congestion periods
Statistical modeling for optimal fee estimation and priority management
Sophisticated Liquidity Aggregation
The Composer integrates liquidity data from diverse sources to create unified, optimized execution paths.
Multi-Source Integration Framework:
Active Sources: Nexus Nodes (CPMM + CLMM) + DotSwap Pool + External APIs
Update Frequency: Real-time curve updates + 100ms refresh cycles
Depth Calculation: Cross-source optimization + slippage minimization
Quality Scoring: Historical performance + current availability metricsIntelligent Routing Algorithms:
Price-First Optimization: Minimize total execution cost including fees and slippage impact Liquidity-First Optimization: Maximize fill probability for large institutional orders Speed-First Optimization: Prioritize fastest execution for time-sensitive trading scenarios Custom Optimization: User-defined preferences balancing multiple execution objectives
Dynamic Rebalancing Capabilities:
Real-time curve adjustments as individual trades execute across the network
Predictive liquidity modeling based on historical trading patterns and market conditions
Automatic route recalculation during execution delays or liquidity changes
Comprehensive failover mechanisms when primary liquidity sources become unavailable
PSBT Construction Excellence
The Composer implements sophisticated transaction construction capabilities that optimize for multiple competing objectives while maintaining security and reliability.
Template Optimization Framework:
Pre-computed PSBT templates for common trading patterns and scenarios
Minimal transaction size optimization through intelligent input/output arrangement
Dynamic fee estimation incorporating current network conditions and user urgency preferences
Support for complex multi-asset, multi-party transactions with conditional execution logic
Risk Management Integration:
Embedded slippage protection through sophisticated conditional output structures
Time-lock mechanisms preventing indefinite fund commitment scenarios
Comprehensive transaction validation preventing malformed or potentially exploitative transactions
Real-time simulation and verification ensuring transaction viability before signature collection initiation
