Lightning Network: Bitcoin at the Speed of Everyday Life

Bitcoin is the final settlement layer. Lightning is the payment layer that lets sats move instantly, cheaply, and globally.

  • Send tiny payments without waiting for block confirmations
  • Pay invoices in seconds
  • Move between on-chain and Lightning using swaps
  • Keep Bitcoin’s base layer as the judge, not the bottleneck
