How can several crypto wallets be assigned to one seed phrase?

Question

Cryptocurrency

Answer 1

HD Wallets
2 - Address prefix

Answer 2

From one seed phrase, you can generate keys to different cryptocurrencies. And secondly, the Seed phrase can be tied to one id, on which you can make as many wallets as you like, and information about them, and about this id, is stored on servers, or locally, on the user's device.
