Pay Proton with Crypto

Proton accepts Bitcoin directly, but only after account creation and only on the Bitcoin network. Its support guide explicitly says it does not support Lightning or any other blockchain for native crypto payments, so SolCard is the broader route when you want to spend other tokens.

Proton says Bitcoin cannot be used for automatic subscription payments and asks BTC users to pay at least 24 hours before renewal. A saved SolCard works better for Mail Plus, Proton Unlimited, Duo, or Family plans that you want rebilled on time.

Proton recommends subscribing on proton.me. Its payment documentation says iOS subscriptions may include a surcharge to cover Apple fees, and third-party app store purchases can follow different billing terms than Proton's own web checkout.

One Proton charge can unlock several services at once. Plans like Proton Unlimited, Duo, and Family combine Mail, Calendar, Drive, Pass, and VPN under one subscription, which makes SolCard practical when one web renewal covers your whole Proton setup.

Proton for Business offers a 14-day trial on supported plans, then automatically converts to a paid subscription unless you cancel before the trial ends. SolCard can cover that normal card-based billing when the trial rolls into a live business plan.

If you move from one paid Proton plan to another, Proton converts unused time into prorated account credits for future payments. If you cancel, the subscription stays active until the end of the current term and then stops renewing.
