Sharding creates a set of different keys (shards) that are independent of each other but associated with each other in the Nova Spektr application for some operations.

A sharded account consists of multiple keys (shards) numbered from 0 to the total number of shards minus 1. Each shard is created with a hard derivation path (//0, //1, //2,...,//N-1)

To add accounts for each network, repeat the previous steps as many times as you want.
