BetaRPC by MevAlphaLeak is an RPC endpoint that protects EVM wallets from misfortunate events, such as paying gas for failed transactions and mitigating front-runners and sandwiches. BetaRPC will back-run a user's wallet transactions to check for rebates.  All BetaRPC operations are carried out on a 'when necessary' basis to avoid delaying simple transactions like token sending.
