What is the Lightning Network?
The Lightning Network is a second-layer payment protocol built on top of Bitcoin. It lets two parties open a payment channel, transact between them an unlimited number of times instantly and for fractions of a cent, and then settle the net balance to the Bitcoin base chain when they're done. Routing across many channels turns a network of two-party channels into a global payment network — without any of those payments touching the base chain.
Lightning vs on-chain Bitcoin
| Factor | Lightning | On-chain |
|---|---|---|
| Settlement speed | < 1 second | 10–60 minutes |
| Fee on a $100 payment | < $0.01 | $1–$5 |
| Fee on a $10,000 payment | < $1 | $1–$5 (size-independent) |
| Throughput | Millions tx/s (theoretical) | ~7 tx/s (network-wide) |
| Privacy | Better (onion-routed) | Transparent on the blockchain |
| Use case fit | Coffee, salary, micropayments, remittance | Large transfers, custody moves, settlement |
| Receive without being online | Limited (mobile node compromises) | Yes |
| Final on-chain confirmation needed | Only at channel close | Every payment |
How a Lightning payment works (without the math)
- 1
Open a channel
Two parties commit BTC to a multi-sig address on the Bitcoin base chain. This is the only on-chain step until they're done. - 2
Transact instantly
They exchange signed balance updates off-chain. Each update is enforceable on-chain at any time — neither party can cheat. - 3
Route through others
If you don't have a direct channel to the recipient, the network finds a path through intermediate nodes. You pay sub-cent routing fees to those nodes. - 4
Close the channel (eventually)
When done, either party broadcasts the final balance to the base chain. The full history disappears; only the net result is recorded.

Lightning wallet options in 2026
| Wallet | Custody | UX | Best for |
|---|---|---|---|
| Lightning Pay | Non-custodial | One-tap | Everyone — Lightning + on-chain + stablecoins + Visa card |
| Wallet of Satoshi | Custodial | One-tap | Beginners moving small sats |

How Lightning Pay abstracts it all
You don't need to know what a channel is, what a routing fee is, or whether your payment hopped through three nodes or thirty. Lightning Pay Wallet manages liquidity, opens and closes channels in the background, and surfaces a single balance you can spend in any way: Lightning, on-chain, Visa card, bill pay, or bank off-ramp.
