⚡️ What is the Lightning Network?

<aside>

The Lightning Network (LN) is a second-layer protocol built on top of Bitcoin that allows for faster and cheaper transactions by processing payments off-chain before settling them on the main blockchain. It’s designed for instant, low-fee transfers ideal for everyday use.

💡 Why Pay via Lightning Network?

<aside>

Lightning payments are fast, secure, and low cost, perfect for BTC invoicing.

This method supports clients who are both comfortable with exchanges and those preferring self-custody wallets.

⚡ Why is it called a Lightning Invoice?

<aside>

It’s called a Lightning invoice because it’s part of the Bitcoin Lightning Network, a layer built on top of Bitcoin that allows instant, low-fee transactions. The invoice contains all the payment details—amount, destination, and expiration—so funds can be sent and confirmed almost “at lightning speed.”
