Llm Trading Agent Security

If you're building an AI agent that can actually send transactions or move money, this gives you a layered defense checklist. It covers prompt injection detection tuned for wallet addresses and transfer commands, hard spend caps with daily limits, mandatory pre-send simulation with slippage checks, circuit breakers that halt on drawdown, and wallet isolation patterns. The examples are Python but the ideas port anywhere. The core insight is right: no single control is enough when a bad LLM output can drain funds. Treat every piece of external data as hostile, simulate before you sign, and keep the agent's keys separate from your treasury.
