## Private Relays

Private relays are specialized services that facilitate the secure and private transmission of transactions directly to block builders. By bypassing the public mempool, these relays prevent searchers from observing and front-running sensitive transaction data.

They provide a critical layer of protection for traders who require high-value execution without the risk of exploitation. Private relays often use encryption or direct peer-to-peer connections to ensure that transaction details remain confidential until they are included in a block.

This technology is a direct response to the prevalence of front-running and sandwich attacks in decentralized finance. It represents a significant shift towards more secure and efficient transaction submission methods.

As the demand for privacy grows, private relays are becoming an integral part of the infrastructure for institutional and sophisticated retail participants.
