# Network Management

Nova Spektr allows the user to operate with more than 65 Substrate-based chains including Polkadot and Kusama. Being an Enterprise application, Nova Spektr network management is flexible, it contains the following set of features:

1. Enable and disable networks.
2. Presets of **RPC nodes** for all networks.
3. **Custom** RPC nodes.
4. **Light Clients** for Polkadot & Kusama.

Please check the table below for a detailed explanation of Connection types.
