hello I've been creating an API that generates wallets from an xpub address, the API allows you to create a user and add an attached xpub to a label this plus a user token is the only thing you need to generate addresses with a url (GET).
apiurl/walletGenerator/get_wallet/token/currency/label
You can find all the information at https://github.com/guxal/xpubWalletGenerator
I would like you to try it and tell me your experience if someone is capable of breaking it I would appreciate it, I am aware that the API authentication method is not the best I would like opinions on this for its improvement.
the source code will be released in due time.
all your help will be appreciated.
If someone is interested in the service and wants to finance its expansion, you can use our url to generate your donation address.
