No, lets say I am managing 100 peoples crypto wallets... if that makes people understand better. I would what a place where I can easily view the wallets, transact, swap , etc .. obviously i don't expect to swap and transact all wallets from one screen but at least view all balances.
You can use a 'watching-only' 'blank' 'descriptor' Bitcoin Core wallet to do this.
You'll just have to import all of those mnemonic seed's derived extended public keys as descriptors.
To do that, follow this guide learn how to create descriptors from the extended public keys and import each descriptor to Bitcoin Core.

http://bitcointalk.org/index.php?topic=5399337.msg60178631#msg60178631The guide is specific to import Electrum master public key(s) (
account extended public key) to Bitcoin Core.
If you can't find a way to export each mnemonic seed's extended public key, import them to an offline Electrum first to get each's master public key, one at a time.
Or use iancoleman's BIP39 tool, select the correct derivation path and get the "
Account Extended Public Key" to be compatible with the guide.
The good thing with this is, you can import as much descriptors your hardware can handle compared to online APIs or SPV wallets with a quite low limit.
The limitation is obviously, it's Bitcoin-only and will require a lot of internet bandwidth and storage space. (
pruning isn't recommended for your use-case)
