How Can a User Submit a Transaction Directly to a Validator, Bypassing the Public Mempool?

A user can submit a transaction directly to a validator or a block builder using a private transaction relay service, such as those provided by Flashbots or similar MEV-mitigation infrastructure. The transaction is bundled into a 'private bundle' and sent off-chain to the builder.

This direct submission bypasses the public mempool, ensuring the transaction is not visible to general-purpose front-running bots before it is included in a block. This process is a key strategy for minimizing MEV exposure.
