To send Bitcoin over the Lightning Network you need a Lightning-capable wallet and, for your first payment, either a Lightning invoice from the recipient or an exchange account that supports Lightning withdrawals. The setup takes about ten minutes and a small amount of Bitcoin. You do not need to run a node or master payment channels to get started.
What is the Lightning Network, and how does it work?
The Lightning Network is a payment layer built on top of Bitcoin that moves transactions off the main blockchain so they settle in seconds for very low fees. Two people lock Bitcoin into a shared channel, update their balances between themselves, and only settle the final state on the Bitcoin blockchain. Payments can route through other channels, so you can pay people without a direct channel.
A channel works like a running tab. Opening one requires an on-chain Bitcoin transaction that locks a starting balance between two parties, after which they exchange signed balance updates off-chain. Only the latest update is valid, and either side can close the channel by broadcasting the final state to the Bitcoin network. The Lightning Network documentation describes this backstop: the blockchain enforces the balance if a participant stops cooperating.
When you pay someone you do not share a channel with, the network finds a path through intermediate nodes, similar to how internet packets are routed. Those intermediaries do not need to be trusted, because each hop settles atomically: the payment either completes in full or fails and returns to you.
- A channel is a two-party balance that starts with an on-chain funding transaction.
- An invoice is a payment request that states an amount and a destination, usually shown as a QR code or a text string beginning with ‘ln’.
- A payment routes across one or more channels and, in most cases, settles in under a second.
How do I send Bitcoin over the Lightning Network?
Sending is a three-step flow: get a Lightning-capable wallet, fund it with a little Bitcoin, then scan or paste the recipient’s invoice and confirm. Receiving is the reverse: you create an invoice or share your Lightning address. The steps below use a non-custodial mobile wallet, which is the easiest self-controlled starting point.
- Download a non-custodial Lightning wallet such as Phoenix or Breez from the official app store, and write down your seed phrase on paper. Never share it, and treat any request for it as phishing.
- Add a small amount of Bitcoin. These wallets let you receive Bitcoin on-chain first, then automatically open a channel with the funds.
- Get the recipient’s Lightning invoice. The person you are paying generates an invoice for a specific amount, shown as a QR code or a string starting with ‘ln’.
- Scan or paste the invoice in your wallet, check the amount and the recipient, then confirm. The payment normally settles within a second or two.
- To receive, tap Receive, set an amount, and share the invoice or your Lightning address with the sender.
If you already hold Bitcoin on an exchange, you can instead withdraw it straight into a Lightning wallet, which avoids paying an on-chain fee first. The steps differ slightly per exchange and are covered in the exchange section below.
Which Lightning wallet should I use? Custodial or non-custodial?
For most people a non-custodial mobile wallet such as Phoenix or Breez is the best first choice: you hold the keys, and the app manages channels and liquidity automatically. Custodial wallets and exchange accounts are simpler but mean someone else holds your Bitcoin. Electrum suits desktop users who want full control, while Wallet of Satoshi is simple but has been custodial.
| Wallet | Custody | Platform | What to know |
|---|---|---|---|
| Phoenix (ACINQ) | Non-custodial | iOS, Android | Open source; channels and liquidity managed automatically |
| Breez / Glow | Non-custodial | iOS, Android | Built on the Breez SDK, which powers the Glow app |
| Electrum | Non-custodial | Desktop (and Android) | Keys stay on your device; Lightning is more hands-on |
| Wallet of Satoshi | Custodial (historically) | iOS, Android | Very simple; left US app stores in November 2023 |
| Exchange wallet (Kraken, Coinbase) | Custodial | Web, mobile | Convenient, but the exchange holds the keys |
The difference is who controls the keys. In a non-custodial wallet you hold a seed phrase that can restore your funds, and no company can freeze or lose them, but you are responsible for the backup. Phoenix is built by ACINQ, published as open source under the Apache 2.0 licence, and it manages channel liquidity automatically while you keep control of the funds.
In a custodial setup the operator holds the keys. Wallet of Satoshi has operated this way, and it pulled its app from US app stores in November 2023, though its current site advertises a self-custody model, so check its terms for your region before funding it. Exchange accounts are also custodial; see our guide on whether it is safe to keep crypto on an exchange.
Electrum is a self-custodial desktop Bitcoin wallet whose keys stay on your computer. It supports Lightning payments but leaves channel management to you, which makes it a better fit for experienced desktop users than for a first Lightning payment; our Electrum guide covers download and signature checks.
How much does Lightning cost compared to on-chain Bitcoin?
Lightning is dramatically cheaper than on-chain Bitcoin for small and medium payments. On-chain fees depend on network congestion and are set per transaction by data size, not by the amount sent, so they can reach several dollars. Lightning routing fees are typically under $0.01, and Coinbase charges 0.1% for Lightning sends while Kraken passes through only the routing fee.
| Method | Typical cost | How the fee is set |
|---|---|---|
| On-chain Bitcoin | Variable; illustratively $1 to $30+ per transaction | Set by demand for block space and transaction data size, not the amount sent (bitcoin.org) |
| Lightning, non-custodial wallet | Usually under $0.01, often under $0.001 | Routing fee across each channel, set by node operators (Kraken) |
| Coinbase Lightning send | 0.1% of the amount, e.g. $1 on $1,000 | Flat percentage announced in April 2024 (The Block) |
| Kraken Lightning withdrawal | Routing fee only, under $0.01 | No added Kraken platform fee (Kraken) |
Worked example, using illustrative amounts. On a $1,000 transfer, Coinbase’s 0.1% Lightning fee is $1, while Kraken and a non-custodial wallet would cost under $0.01 in routing fees. An on-chain Bitcoin transaction is priced by data size rather than value, so the same $1,000 could cost about $1 in a quiet mempool or more than $30 when the network is congested. These figures are illustrative, not live quotes, because on-chain fees move constantly, which is why on-chain confirmation times and costs vary.
Lightning has one small setup cost you may meet once: opening a channel requires an on-chain transaction, so your first funding payment pays a normal Bitcoin fee. After that, payments within your channel capacity avoid on-chain fees entirely.
Bitcoin and other crypto assets are volatile, and this is not financial advice.
Which exchanges support Lightning withdrawals?
Kraken supports Bitcoin withdrawals and deposits over Lightning, and its support guide sets out the exact steps; the account must be verified to Intermediate or Pro level. Coinbase began rolling out Lightning support on 30 April 2024 with a 0.1% fee on Lightning sends and a $2,000 per-withdrawal limit at launch, and support was not available in every region.
Kraken supports Bitcoin withdrawals and deposits over Lightning. As of November 2026 its help guide lists this flow: verify your account to Intermediate or Pro level, choose Withdraw, select BTC and then Lightning Network, then create a Lightning request in your wallet for the exact amount and paste it in. Kraken confirms the withdrawal by email before it is broadcast, and it suggests on-chain for larger transfers, roughly above 0.1 BTC.
Coinbase added Lightning in partnership with the non-custodial provider Lightspark, rolling it out on 30 April 2024. At launch Coinbase charged 0.1% on Lightning sends and limited withdrawals to $2,000, a maximum fee of $2, and the rollout was gradual and region-dependent rather than available everywhere at once, so check your account for the option.
Both exchange wallets are custodial by nature: while Bitcoin sits in an exchange account, the exchange controls the keys. If you want full control, withdraw to a non-custodial wallet. Our guide on moving crypto from an exchange to a wallet covers the general steps.
What are the common Lightning mistakes, and how do I avoid them?
The most common mistakes are sending to the wrong network, assuming receiving works instantly, leaving a channel partner offline for too long, and keeping Bitcoin in a custodial wallet you do not control. Check the address type before confirming, use a wallet that manages liquidity automatically, and never share your seed phrase with anyone.
- Pasting an on-chain address into a Lightning field, or vice versa. A Lightning request begins with ‘ln’, while on-chain Bitcoin addresses use a different format, and the two are not interchangeable. Check before confirming.
- Assuming you can always receive. A new channel needs inbound capacity before money can flow to you. Mobile wallets such as Phoenix and Breez handle this automatically; a manual wallet like Electrum does not.
- Going offline while a channel is open. If your channel peer disappears or tries to cheat, a timely close or a watchtower protects you. For everyday amounts this is a minor risk, but it is why non-custodial wallets keep you synced.
- Trusting a custodial wallet with money you cannot afford to lose. The operator holds the keys; Wallet of Satoshi leaving the US market in 2023 is a reminder to check custody before you deposit.
- Sharing your seed phrase. No wallet, exchange or support agent will ever legitimately ask for it. Anyone who does is running a phishing scam.
Is the Bitcoin Lightning Network safe?
Yes, in the sense that Lightning inherits Bitcoin’s security: balances are enforced by Bitcoin transactions, and either party can close a channel on-chain if the other stops cooperating. The realistic risks are operational rather than cryptographic: staying offline, mismanaging channels, and holding funds with a custodial operator you have not vetted.
Every channel is backed by an on-chain Bitcoin transaction, and the most recent signed balance is the one that can be enforced. If a peer stops responding or tries to broadcast an old balance, the other side can close the channel and claim its current balance on the Bitcoin blockchain. This backstop is what makes routing through strangers possible.
The practical safety concerns are user-level. Keep your seed phrase offline and secret, use a reputable wallet from the official app store or vendor site, and watch for phishing pages that imitate real wallet downloads. For a full run-down of wallet types, see our wallets hub.
