Architecture

EventMonitor → PERCEIVE (balances, events, portfolio)
                  ↓
              REASON (Claude + tool-use)
                  ↓
              ACT (Guardian safety checks → execute → audit)
                  ↓
              REFLECT (update portfolio, log metrics)
                  ↓
              sleep → loop

Security

• Keys encrypted at rest (Fernet + PBKDF2, 600k iterations)
• Per-transaction, hourly, and daily USD spending caps
• Human-in-the-loop approval for high-value transactions
• Slippage protection on all swaps
• Append-only audit log
