How to avoid sandwich attacks

Sandwich bots cost DeFi users millions a year — but stopping them takes one setting.

A sandwich attack only works if a bot can see your trade in the public mempool first. Take your transaction out of that public view and the attack has nothing to target. The fix is a one-time setting.

Top picks

1Private RPC

MMEV Blocker

Add it as your wallet RPC and you’re protected on every dApp — plus you earn up to 90% of any back-run value.

2Private RPC

FFlashbots Protect

The conservative alternative RPC; rotate between the two for very large trades.

3Intent DEX

11inch Fusion

If you mostly swap, intent-based execution sidesteps sandwiching entirely — and is gasless.

Bottom line

The simplest fix: set MEV Blocker or Flashbots Protect as your wallet RPC. For swaps, 1inch Fusion or CoW Swap protect you by design.
