### FAQMEV (Maximal Extractable Value) occurs when bots exploit your transactions for profit. Common types include frontrunning (copying your trade ahead of you) and sandwich attacks (trading before and after your transaction to extract value). MEV has extracted over $1.43 billion from Ethereum users across trading, DeFi, and NFT transactions.MEV Blocker protects you from these attacks while ensuring you get rebated when your transactions create backrunning opportunities.An RPC (remote procedure call) endpoint is used to connect applications like wallets to the blockchain.MEV Blocker is a special RPC endpoint that ensures your trades are protected from MEV. It does this by sending your transaction to a network of searchers that scan for backrunning opportunities, but cannot frontrun or sandwich your trades.You can add RPC endpoints like MEV Blocker by changing the selected network in your crypto wallet. Some DeFi trading apps will also be able to integrate the MEV Blocker RPC endpoint directly — making it a default for all users. Get in touch if you're interested in doing this!What kinds of MEV does MEV Blocker protect from?MEV blocker protects from most kinds of frontrunning, but especially from trade sandwiching, which is when a searcher trades just before and just after your transaction to make a profit.How does MEV Blocker RPC give you a rebate and when?MEV Blocker also lets you benefit from backrunning. It does this by allowing searchers to “bid” in an auction to win the right to backrun your trade. When this happens, users of MEV Blocker receive 90% of the profit their backrunning opportunity creates (compared with 0% when not using MEV Blocker).The rebate is paid to the user that sent the transaction (tx.origin), immediately in the same block.The same call, in code.
