Are you sure about that? From Mollie's webiste:

Mollie B.V. is licensed and registered as an electronic money institution with the Dutch Central Bank (relationship number: F0038). Mollie UK Ltd is licensed and registered with the Financial Conduct Authority as a payment institution in the UK (FRN: 977968).

Lightspeed is powered by Adyen and serves smaller businesses.

Seems to be focused on retail / POS, not online payments. Though they do have eCommerce page and even API:

Mollie also doesn't want small businesses, unfortunately. (We were rejected as too small.)

Matches my experience. They didn’t state any reason in my case, though.

Really? Must be a recent thing then..? I've used them for all sorts of small (and not so small) things.

Mollie doesn't resell Adyen, nor does it rely on Adyen's banking license.
