A recent change in the Stripe API, accompanied by a shift in Stripe’s handling of Bitcoin has prompted us to switch to CoinPayments.net directly for handling cryptocurrency. Payments processed through the CoinPayments.net gateway will still ultimately be processed by our CoinBase account, but will no longer be initialized via Stripe.
On the checkout page, CoinPayments.net is now listed as an additional gateway. Selecting that and clicking Place Order will transfer you to a page hosted by CoinPayments.net, where you may select Bitcoin or another one of a number of different cryptocurrencies.
Please note that as a result of this change, the Bitcoin Payment Policy has been superseded by the new Cryptocurrency Payment Policy (though the former will remain available for historical purposes).
