What is a Lightning address?
Short answer. A Lightning address lets you receive Bitcoin. It looks like an email address, such as [email protected]. Anyone with a compatible Lightning wallet can pay you any amount, at any time. They do not need to ask you for an invoice first.
Lightning is a fast payment network on top of Bitcoin. Before Lightning addresses, every payment needed a fresh invoice: a long code made for one payment only. That works at a shop counter. It is clumsy when a client, a fan or a friend wants to pay you later.
A Lightning address fixes that. You give out one short address, once. It fits on an invoice, a website, a social profile or a business card.
How it works, in three steps
- The payer types your address, for example [email protected], and an amount.
- Their wallet asks the server behind paykute.com for a fresh invoice for you.
- The wallet pays that invoice, and the Bitcoin arrives in your wallet.
The payer never sees the invoice. For both of you, it works like an email address.
Who runs the server?
Every Lightning address needs a server that answers the payer's wallet. Kute uses Breez software for Lightning, and paykute.com addresses go through the hosted service of Breez. The server hands out invoices. It does not hold your keys or your money. Your keys stay on your phone.
Your Kute Lightning address
- Every Kute wallet gets one. A new wallet starts with a random name, an adjective plus a sea word plus a 4-digit number.
- You can edit the name on the Receive screen. Names use lower case letters, numbers, dots, dashes and underscores.
- If you restore your wallet from your 12 words, the app finds your existing Lightning address again.
- The same Receive screen offers a one-time Lightning invoice when you want to ask for an exact amount.
Lightning address, invoice or Bitcoin address?
| Lightning address | Lightning invoice | Bitcoin address | |
|---|---|---|---|
| Looks like | [email protected] | A long code or QR | A long code or QR |
| Use it | Again and again | Once | Best once per payment |
| Who sets the amount | The payer | You | The payer |
| Speed | Seconds | Seconds | Minutes or more |
| Good for | Invoices, tips, friends | An exact amount, now | Large payments to keep |
Lightning addresses are not only a Kute idea. Other wallets offer them too. Wallet of Satoshi, for example, lists "sharing your own custom Lightning Address" on its Google Play page (listing, checked 20 October 2026). That is the point: there is one standard, and any compatible wallet can pay any Lightning address.
Is it safe to post my Lightning address in public?
Yes. People can only send you money with it. They cannot take money out. One thing to know: a public Lightning address links payments to a name that you chose. To keep a payment apart from your public name, make a one-time invoice instead.

Questions people ask
Yes. In Kute you can edit the name on the Receive screen. Tell your clients if you change it, because the old name no longer sends money to you.
