 ### Component interactions
 
 - Engineers use a CLI to manage the backend components, installing and initializing various modes of operation, such as validium versus rollup for example.
-- External applications send transactions to the CDK Erigon RPC node which forwards the transaction data to the sequencer via the transaction pool manager.
+- Once a chain is configured with the CLI, users can submit transactions through the CDK Erigon RPC node. These transactions are relayed to the `tx-pool manager` before the sequencer selects and executes them.
 - The sequencer sequences transactions batches and synchronizes data with the RPC node.
 - The sequencer sender reads batch data from the RPC node.
 - The aggregator reads batch data from the sequencer data stream.
