Lightning Network
A layer built on top of Bitcoin that settles small payments almost instantly with very low fees.
The Lightning Network is a second layer for Bitcoin. Users open payment channels backed by on-chain Bitcoin and route payments through a network of channels, settling to the main chain only when channels open or close.
Why it matters for casino players
On-chain Bitcoin deposits can take 10 minutes to an hour and cost more when the network is busy. Lightning payments usually arrive in seconds for a tiny fee. A growing number of crypto casinos accept Lightning deposits, and some pay withdrawals over Lightning.
How it differs
- You pay an invoice rather than sending to an address. Invoices usually start with "lnbc" and expire.
- You need a Lightning-capable wallet.
- Large payments can fail if no route has enough capacity, so casinos often cap Lightning withdrawals.
Common mistake
Do not send on-chain Bitcoin to a Lightning invoice, or try to pay a Lightning invoice from an on-chain-only wallet. Use the option that matches your wallet.
