Description

Implement the Blink GraphQL API as an option to use as a funding source in LNbits allowing Blink accounts to leverage the full features of the LNbits suite with it's extensions without having to run a Lightning Node.

Background

Making Blink accounts available to be a funding source for LNbits could make the many features of LNbits more easily available for a wider audience by taking over the burden of lightning node management.

Task

Submit a PR to LNbits that will allow Blink users to use an API key obtained via the Blink Dashboard to connect their Blink account as the funding source for LNbits.

Implementation notes

As the first step it could be enough to use the BTC denominated account only to send and receive, but a further integration could be to handle wallets and calls denominated in USD. The implementation design should consider this feature to be possible in the future.

The currently available funding sources are listed here: https://github.com/lnbits/lnbits/tree/dev/lnbits/wallets

Blink already has FOSS plugins for BTCPay Server, Alby and a python based LightningATM which can be used as implementation examples.
