Unfortunately wallet of satoshi is unavailable in the US and Alby is invite only. You can use Strike as your receiving address for now, but it has a minimum amount for sending that will make it inconvenient for sending small zaps. You can use Phoenix to send, but not to receive to a static address. The lightning ecosystem is a bit of a mess right now, sorry. I recommend installing the Alby extension on a desktop web browser and signing up and waiting for an invite code. Once you get alby set up, you can connect Amethyst to it and you'll be able to send one tap zaps in Amethyst. In the mean time, use Strike to receive and Phoenix to send. It's not ideal but it will work.
