LLM交易代理安全性

為擁有錢包或交易權限的自動化交易代理提供安全模式。涵蓋提示注入、支出限制、發送前模擬、斷路器、MEV保護和金鑰處理。當自主代理持有錢包或交易權限,且其限制、模擬或金鑰處理需要審查時使用。

LLM交易代理安全性 是什麼?

此技能為自主交易代理提供關鍵安全模式。它解決了代理直接控制錢包或交易權限時獨有的威脅模型:提示注入或錯誤工具使用可能導致資產直接損失。技能要求多層防禦,包括輸入淨化(過濾注入模式)、硬性支出限制(獨立於模型輸出強制執行單筆交易和每日限額)、發送前模擬(確保滑點可接受)、斷路器(監控連續損失或小時虧損閾值)、錢包隔離(僅使用專用熱錢包,非主要資金庫錢包),以及MEV和截止期限保護(設置私有的RPC、最大滑點和截止期限)。它附帶一個部署前清單,涵蓋資料衛生、獨立支出限制和強制模擬等項目。支援基於Python的代理,並提供程式碼範例。

LLM交易代理安全性 是做什麼的?

自主交易代理比普通的LLM應用面臨更嚴峻的威脅模型:一次注入或錯誤的工具路徑可直接導致資產損失。

何時使用

  • 構建一個簽署並發送交易的AI代理
  • 審計交易機器人或鏈上執行助手
  • 為代理設計錢包金鑰管理
  • 賦予LLM訂單下達、交換或資金庫操作的權限

運作方式

層層防禦。沒有任何單一檢查是足夠的。將提示衛生、支出政策、模擬、執行限制和錢包隔離視為獨立的控制項。

範例

將提示注入視為金融攻擊

import re

INJECTION_PATTERNS = [
    r'ignore (previous|all) instructions',
    r'new (task|directive|instruction)',
    r'system prompt',
    r'send .{0,50} to 0x[0-9a-fA-F]{40}',
    r'transfer .{0,50} to',
    r'approve .{0,50} for',
]

def sanitize_onchain_data(text: str) -> str:
    for pattern in INJECTION_PATTERNS:
        if re.search(pattern, text, re.IGNORECASE):
            raise ValueError(f"可能的提示注入:{text[:100]}")
    return text

不要將代幣名稱、交易對標籤、webhook或社交Feed盲目注入到有執行能力的提示中。

硬性支出限制

from decimal import Decimal

MAX_SINGLE_TX_USD = Decimal("500")
MAX_DAILY_SPEND_USD = Decimal("2000")

class SpendLimitError(Exception):
    pass

class SpendLimitGuard:
    def check_and_record(self, usd_amount: Decimal) -> None:
        if usd_amount > MAX_SINGLE_TX_USD:
            raise SpendLimitError(f"單筆交易 ${usd_amount} 超過上限 ${MAX_SINGLE_TX_USD}")

        daily = self._get_24h_spend()
        if daily + usd_amount > MAX_DAILY_SPEND_USD:
            raise SpendLimitError(f"每日限額:${daily} + ${usd_amount} > ${MAX_DAILY_SPEND_USD}")

        self._record_spend(usd_amount)

發送前模擬

class SlippageError(Exception):
    pass

async def safe_execute(self, tx: dict, expected_min_out: int | None = None) -> str:
    sim_result = await self.w3.eth.call(tx)

    if expected_min_out is None:
        raise ValueError("發送前需要設定 min_amount_out")

    actual_out = decode_uint256(sim_result)
    if actual_out < expected_min_out:
        raise SlippageError(f"模擬結果:{actual_out} < {expected_min_out}")

    signed = self.account.sign_transaction(tx)
    return await self.w3.eth.send_raw_transaction(signed.raw_transaction)

斷路器

class TradingCircuitBreaker:
    MAX_CONSECUTIVE_LOSSES = 3
    MAX_HOURLY_LOSS_PCT = 0.05

    def check(self, portfolio_value: float) -> None:
        if self.consecutive_losses >= self.MAX_CONSECUTIVE_LOSSES:
            self.halt("連續虧損次數過多")

        if self.hour_start_value <= 0:
            self.halt("hour_start_value 無效")
            return

        hourly_pnl = (portfolio_value - self.hour_start_value) / self.hour_start_value
        if hourly_pnl < -self.MAX_HOURLY_LOSS_PCT:
            self.halt(f"小時PnL {hourly_pnl:.1%} 低於閾值")

錢包隔離

import os
from eth_account import Account

private_key = os.environ.get("TRADING_WALLET_PRIVATE_KEY")
if not private_key:
    raise EnvironmentError("未設置 TRADING_WALLET_PRIVATE_KEY")

account = Account.from_key(private_key)

使用一個僅包含所需會話資金的專用熱錢包。切勿將代理指向主要資金庫錢包。

MEV和截止期限保護

import time

PRIVATE_RPC = "https://rpc.flashbots.net"
MAX_SLIPPAGE_BPS = {"stable": 10, "volatile": 50}
deadline = int(time.time()) + 60

部署前檢查清單

  • 外部資料在進入LLM上下文前經過淨化
  • 支出限制獨立於模型輸出強制執行
  • 交易在發送前進行模擬
  • min_amount_out 為必填項
  • 斷路器在回撤或無效狀態時停止交易
  • 金鑰來自環境變數或秘密管理器,而非代碼或日誌
  • 在適當情況下使用私有記憶體池或受保護的路由
  • 根據策略設置滑點和截止期限
  • 所有代理決策都有審計日誌,不僅是成功發送

Produces severity-ranked findings with code-first fixes. Essential for developers building agent applications, autonomous loops, or any LLM-powered feature. Use when an agent or LLM feature misbehaves and the failing layer is unknown, or before shipping an agent stack.

agent-eval

Head-to-head comparison of coding agents (Claude Code, Aider, Codex, etc.) on custom tasks with pass rate, cost, time, and consistency metrics. Use when choosing between coding agents, or when a change to an agent setup needs measured pass rate, cost, and time rather than an impression.

agent-harness-construction

Design and optimize AI agent action spaces, tool definitions, and observation formatting for higher completion rates. Use when defining or revising an agent

agentic-engineering

Operate as an agentic engineer using eval-first execution, decomposition, and cost-aware model routing. Use when planning or executing engineering work that agents will carry out end to end.

ai-regression-testing

Regression testing strategies for AI-assisted development.
