 The Payments system streamlines user interactions with EigenDA, offering clear, flexible options for managing network
 bandwidth. EigenDA supports two flexible payment modalities:
 
-1. **On-demand Bandwidth**: Users can make pre-paid payments for occasional bandwidth usage without time limitations or
-   throughput guarantees, and payments are recorded per blob dispersal request. Charges are applied only when the
-   request is successfully validated by the disperser server, providing flexibility for users with dynamic bandwidth
-   requirements.

 2. **Reserved Bandwidth**: Users can reserve bandwidth for a fixed time period by pre-paying for system capacity, ensuring consistent and reliable throughput at discounted prices.
