Thanks for the anwser. Yes, the seed/mnemonic phrase, the wallet itself, is generated in the device using BDK libraries.

Also, the Database with the info is also stored in the device, making me think it is non-custodial. Yes, Eletrcum server is used to get blockchain data etc. Thanks for the answer!

I'm searching some projects using BDK and sometimes i just confuse basic concepts.

For example, this wallet: https://github.com/thunderbiscuit/devkit-wallet , implements a wallet using BDK connecting to a Electrum server. Is it considered Custodial or Non-Custodial ?

Sorry if it is a dumb question before hand, just confusing who "has" or doesn't "have" the keys.
