In DeFi, MEV (Maximal Extractable Value) attacks exploit the transparency of blockchain transactions. Bots monitor pending transactions and front-run users by inserting their own trades just before, resulting in:
• Front-running: Your trade is copied and executed ahead of yours, making it more expensive.
• Sandwich attacks: Bots buy before and sell after your trade to extract value from your slippage.
• Loss of privacy: Every trade is public before it is finalized, revealing your strategy.

This leads to unfair pricing, higher fees, and loss of trust in decentralized markets.

The Solution: ZKShield

ZKShield protects users from MEV by using zero-knowledge proofs and a commit-reveal scheme that hides trade details until they are executed. Users commit to a trade off-chain, generate a ZK proof that verifies its validity, and only reveal the trade once it’s safe.

This prevents bots from reading trade intent in the mempool and ensures fair, private, and MEV-resistant trading.
