# Execution Layer

The execution layer is responsible for the fulfillment of the order and ensuring its successful finalization. Once an order’s solution batch has been prioritized by Socrates, the transaction builder takes over to facilitate the actual transaction data code using an [<mark style="color:purple;">open-source transaction building library</mark>](https://github.com/grixprotocol) (managed by Grix). It then ships the built transaction to an automated execution network (such as Gelato) to be executed.

Finally, the transaction is transmitted to the blockchain through the Grix router contract. The router also deducts fees and channels them to the fees pool, which then distributes these fees between the protocol and the solvers.

The execution layer also manages the intricacies of transaction execution and ensures that each trade is processed fast, securely, efficiently, and in compliance with the priorities and protocol fees agreed by the user.
