This is the second recent account I've heard of a company using LNBits as their "payments account layer" (the other isn't public about it).
LNbits provided DFX with a modular, open-source solution that allows them to build only what they need, without locking into a rigid platform. For instance, DFX built custom monitoring around payment events using the LNbits API, while keeping full control over wallet infrastructure.The ability to generate and manage LNURLs through the LNbits API, while layering additional monitoring and business logic on top, made LNbits a practical choice.
