This implementation is for demo purposes only and does not reflect all limitations and constraints of a live distributed network.

Transaction Provider is an embedded solution to demonstrate an interface an application could leverage to extract MEV when building and proposing a block. In this example, the application is building and signing transactions locally for the sake of a simplicity. Alternatively, another implementation could instead take transactions submitted directly via RPC to its app side mempool, and could even implement a separate custom mempool for special transactions of this nature.
