There is no “Standard” #Zap you can send whatever you feel like sending, just be aware based on what Wallet you are sending from there might be a fee associated with it. The 21 #Sats #Zaps are a mini tribute to the total supply of #Bitcoin being at 21million. And well we all know why #69 is a favorite. You can set your standard #Sats rate in the settings part of your account. You can also #DoubleTap the #Zap button to give you more options and also it will let you add a custom note alongside your #Zap if you feel so inclined 🤙🤙⚡️⚡️⚡️⚡️⚡️⚡️
