A clear explanation of sandwich attacks, slippage exposure, MEV bots, and why DEX users should avoid careless settings.
Quick judgment: this page is part of the Eonwell DEX knowledge path. It is designed to help readers understand swaps, liquidity, routes, approvals, network differences, and safer trading habits before using decentralized exchanges.
Core idea
A sandwich attack is a trading pattern where a user's swap is placed between two attacker transactions.
The attacker can push the price before the user's trade and then trade back after it.
High slippage tolerance and visible pending transactions can increase exposure.
Users can reduce risk by avoiding excessive slippage and using safer routing or protected execution where available.
Practical checklist
- Avoid extreme slippage.
- Watch price impact.
- Avoid large swaps in shallow pools.
- Use reputable routers and protection tools when appropriate.
Common mistake
A common mistake is treating a DEX swap as a simple button press. In reality, a swap may include wallet connection, network selection, token approval, routing, slippage tolerance, gas estimation, and final transaction confirmation. Each step should be checked before signing.
How this connects to Eonwell
DEX knowledge connects wallet safety, token verification, liquidity awareness, and presale judgment. Once a reader understands how decentralized exchanges work across Ethereum, BNB Chain, Solana, and Layer 2 networks, they can make cleaner decisions before interacting with new tokens or DeFi apps.
