Lightning Network transfer shows up in El Salvador as part of how people buy bitcoin locally, even though none of the exchanges we track lists it as a direct funding rail. The country guides below explain what that looks like in practice.
What is Lightning Network transfer?
The Lightning Network is a payment layer built on top of Bitcoin rather than a company or a scheme. Two parties lock bitcoin into a channel, then pay each other by re signing how that balance is split, and a payment can hop across a chain of channels to reach someone you have no channel with. Only opening and closing a channel touches the Bitcoin blockchain, so the payments in between never wait for a block. The rules are the open BOLT specification, maintained in public by the people who write the implementations, and exchanges or wallets that support it let you deposit bitcoin this way instead of sending an ordinary on chain transaction.
- Speed
- Payments clear off chain, so a deposit normally lands in seconds instead of waiting for a Bitcoin block confirmation.
- Cost
- Each node along the route charges fee_base_msat plus the amount multiplied by fee_proportional_millionths divided by 1,000,000, quoted in millisatoshis, so the total depends on the route rather than on a published tariff.
- Limits
- Payment size is capped by the capacity of the channels it routes through, and the specification held standard channel funding below 2^24 satoshis, about 0.168 BTC, unless both peers advertise option_support_large_channel.
Speed and cost describe the rail itself. What an exchange adds on top varies by platform and is shown per exchange below.
