Why Pay From Your Wallet

Crypto tends to win when cards get in the way: cross border declines, recurring charge blocks, or a preference for not handing card details to another vendor.

Confirms, Then Activates

The plan applies as soon as the network confirms your transfer. That is usually minutes, against the days an international bank transfer can take.

Nothing to Breach

Paying from a wallet means there is no card number, CVV, or billing address stored anywhere in our systems for an attacker to go after later.

Works From Anywhere

No issuer declining a foreign merchant, no bank blocking a recurring charge. If you can broadcast a transaction, you can buy a plan.

40+ Coins Accepted

Bitcoin, Ethereum, the major stablecoins, and dozens more. Pick whichever your wallet already holds and pay the quoted amount.

You Choose the Timing

Renewals are paid invoice by invoice instead of pulled automatically, so funds leave your wallet only when you decide to send them.

Records Kept Both Ways

Each payment lands against a dated invoice with the transaction reference stored next to it, which keeps your bookkeeping straightforward.

FAQ

FAQ

Rates, confirmation times, underpayments, and refunds: the things worth knowing before you broadcast a transaction to us.

More than 40 major coins are supported, including Bitcoin, Ethereum, and the widely traded stablecoins. The full list appears at checkout once you pick crypto as the payment method.

Yes. Plans are priced in US dollars and the payment page quotes an exact coin amount held for a short window. Send within that window and the invoice settles at the quoted rate.

Activation waits on network confirmation rather than on us. Most transfers confirm within minutes, and the quota lifts automatically as soon as the payment is recorded against your invoice.

An underpaid invoice stays open rather than failing. Send the shortfall to the same address, or contact support with the transaction reference and we will reconcile it against your account.

No. There is no way to pull funds from your wallet, so each renewal is paid per invoice. You pick the number of months you want, we email you before the period ends, and a two week grace period keeps the plan active while you pay.

Every crypto payment is filed against a dated invoice in your dashboard, with the on chain transaction reference kept alongside it for your own accounting trail.

No. Crypto payments are final. On chain transfers cannot be reversed and coin prices shift constantly, so we do not send funds back to a wallet. If a transfer fails to record against your invoice, contact support with the transaction reference.

Yes. Payment method is chosen per invoice, so you can pay one month in crypto and the next by card or PayPal without changing anything about your sending setup.
