Prevention Strategies

Protecting against front-running requires a multi-layered approach. From simple slippage limits to advanced cryptographic schemes, each strategy offers different tradeoffs between security, cost, and complexity.

Slippage Tolerance

Set maximum acceptable price deviation to limit attack profitability

None

Tradeoffs

Transactions may fail in volatile markets

Code Example:

// Uniswap V2 example
swapExactETHForTokens(
  amountOutMin: 95, // Accept max 5% slippage
  path: [WETH, USDC],
  deadline: block.timestamp + 300
)

🛡️ Choosing the Right Strategy

For retail users: Slippage tolerance + Flashbots Protect RPC (free, easy)

For protocols: Private RPC + Transaction batching (moderate cost, good protection)

For high-value txs: Commit-reveal + Private mempool (maximum security)

For DeFi protocols: Batch auctions (CoW Protocol model) + MEV share agreements
