Free, permissionless protection against frontrunning and sandwiches, competitive backrun rebates, fast inclusion, transparent auction data, and selectable fast, no-revert, and full-privacy endpoints; narrowly beats Flashbots for typical DeFi users because its endpoint choices expose clearer speed/privacy/rebate trade-offs.
Gemini It offers the most practitioner-friendly model for typical DeFi users by running an Order Flow Auction (OFA) that shields trades from front-running and sandwiches while automatically returning 90 percent of backrunning bids as rebates. It is in a near-tie with Flashbots Protect, but ranks first due to its seamless, zero-config rebate mechanism.
Grok Tops independent benchmarks for fastest inclusion (1.34 blocks avg), highest MEV rebates (~0.0035 ETH), strong success rate (85%), and effective protection against frontrunning/sandwiches via broad builder coverage and backrun auctions; free, fast, and widely adopted for everyday DeFi/trading use as of 2026.
Claude Built by CoW DAO with a large searcher network that auctions backrun rights and returns ~90% of captured value to the user, historically the most generous rebate model; free, permissionless, wide wallet adoption, and near-tie with Flashbots Protect — it edges ahead on user rebates, behind on operator neutrality and builder reach
Where MEV Blocker falls short, per the models
- GPT Ethereum-mainnet-only, and protection still cannot guarantee safety during reorgs or prevent losses from excessively loose slippage.
- Claude Protection depends on its searcher/builder consortium honoring rules rather than a single trusted operator, and complex transactions can see more variable inclusion times than Flashbots' pipeline
- Gemini It leaks transaction intent data to a whitelist of searchers for bidding, and it can suffer from slightly slower inclusion times compared to direct builder routing.
- Grok Not ideal for users prioritizing strict revert protection (more limited than Flashbots) or those needing enterprise SLAs/compliance over pure performance.
