Smart Transactions 

Про 

Smart Transactions are a type of blockchain transaction that gets executed depending on the timing of when a specialized entity, often called a solver, chooses to process it. Smart Transactions is built on a set of smart contracts designed to handle transactions with specific timing or conditional features. Participants can submit these transactions to a special queue, called a mempool, for later execution. Users can customize these transactions to include protections against frontrunning and backrunning or to execute only when certain conditions are met.
