Getting started
Most people's first Lightning payment is through a mobile wallet. The choice is the same as everywhere in Bitcoin: who holds the keys?
- Custodial. The provider runs the node and holds the funds; you have an account. Setup takes a minute. It is a bank account denominated in sats, with the provider's risks.
- Self-custodial. You hold the keys. Modern wallets open channels for you automatically, usually through a liquidity provider that charges a small fee, so you do not manage channels by hand. You need to back up the seed and often a channel state file, and your phone has to be on to receive.
Sending and receiving
- To receive, tap Receive and share the invoice or QR, or give your Lightning address.
- To send, scan an invoice, check the amount and destination, confirm. It settles in a second or two.
- Fees are usually a few sats. Failed payments cost nothing; the wallet retries other routes.
Good practice
- Treat a Lightning wallet like the cash in your pocket: spending money, not savings. Move larger amounts to on-chain cold storage.
- Back up what the wallet asks you to back up. Some self-custodial wallets need a channel backup as well as the seed.
- Test with a small payment to a friend or a tipping site before relying on it.
