Hmm.
Iβm not sure if there is a good way to store this securely since it has to all be read by the server based on a trigger of a βlikeβ and not some explicit action from the zapper (I.e. making an API call and decrypting the encrypted string to make the payment).
Only solution I can think of is running a βpersonalβ zap agent on your computer for yourself that performs the same function.
Youβd still need to protect your nwc info but at least youβd be responsible for yourself.
