Trace — AI Trading Agent

Nexus-8004 is a cryptographically verifiable multi-agent AI trading system built on the ERC-8004 trust standard. It solves the most critical problem in AI trading: how do you actually trust an autonomous agent with your money? Most AI trading bots are black boxes — they claim returns, but there's no way to verify decisions, reasoning, or performance history. Nexus-8004 changes this with a 5-layer orthogonal architecture: Layer 1 (Perception): A dual-brain signal engine — LimiX-16M (a Transformer using In-Context Learning for quantitative signals) paired with an LLM NLP engine for sentiment analysis and risk veto. Layer 2 (Memory & Reflexion): ChromaDB episodic memory with Pre-Trade RAG self-correction. The agent retrieves similar historical contexts before each trade and adjusts confidence accordingly — preventing repeated mistakes. Layer 3 (Tripartite Agents): A three-branch governance system: TradePlanner (legislature), TradeGenerator running an adversarial Bull vs. Bear debate (executive), and TradeEvaluator enforcing 6 hard veto rules (judiciary). Layer 4 (Execution Skills): Half-Kelly position sizing, pre-execution risk DryRun simulation, and deterministic Kraken CLI order execution. The LLM never touches math — all arithmetic is handled by validated Python. Layer 5 (ERC-8004 Trust): Every TradeIntent is EIP-712 signed. After each trade, real PnL and the CoT reasoning hash are written to the Reputation Registry on-chain — creating an immutable, publicly verifiable performance record. Backtest results (Oct 2025 – Mar 2026): ETHUSDT +23.8% (Sharpe 83.9), SOLUSDT +12.9%, BNBUSDT +11.3%, DOGEUSDT +11.3%, BTCUSDT +5.5%. Paper trading NAV grew from $10,000 to $11,231.
