Moon is a crypto payment-processing start-up that works by allowing lightning network-enabled wallets to be used through Moon's browser extension.
The extension allows shoppers to connect their cryptocurrency wallet to it, for example, a Coinbase wallet, and use it at checkout, to pay for goods with bitcoin, or one of three other currencies, litecoin, ethereum or bitcoin cash.
Let's be clear it's not a native Amazon payment option … yet.
In an interview with CCN.com CEO Ken Kruger explained how Moon worked:
Simply: After installing the Moon browser extension you shop on Amazon.com as you normally would. At checkout, Moon gives you the option to pay with your crypto. When you submit payment, your purchase is completed instantly and seamlessly on Amazon … We'll be expanding to other wallet integrations and currencies.
