Lightning, told plainly
Lightning routing economics: how your node earns
Your Lightning node can earn sats by forwarding other people's payments. Here is how routing works, how fees and liquidity work together, and how thoughtful node runners turn open channels into steady income.

01What a routing node is
A Lightning payment usually hops from channel to channel before it reaches its destination. Your routing node sits along those paths, forwarding other people's payments and collecting a tiny toll on each one. Every hop is instant, and the tolls add up into real sats over time.
Picture a friendly corner shop on a busy street. Travelers pass through all day, and each leaves a tiny coin behind. A well connected node becomes that kind of corner, useful to the network and quietly productive for you.
02Liquidity as inventory
Every channel holds sats on both sides. Outbound capacity sends payments out through your channel, and inbound capacity lets payments flow in toward you. Routing moves sats across your channels, so you want room on both sides to keep traffic moving.
Think of it like shelves in a shop. Stock on both sides keeps the flow smooth, and watching the levels tells you when a channel is ready for a tune up.
03Setting your fees
Two knobs control what you earn per forwarded payment. The base fee is a tiny flat charge added to each payment, and the proportional rate is measured in parts per million, called ppm. A 100 ppm rate collects 100 sats from every million sats forwarded.
Fair fees on well placed channels see steady flow. Busy routes support a slightly higher rate, while quieter routes earn more by staying competitive. Adjusting the knobs and watching the flow is the heart of the craft.
04Opening channels with purpose
Open channels where payments actually travel: busy wallets, popular merchants, and well connected hubs that forward heavy volume. A channel to a lively corner earns lively income, so placement matters more than the number of channels.
Spread your sats across several partners rather than one. Start modest, watch where the flow goes, then grow the channels that move.
05Rebalancing your channels
Payments push sats in one direction, so channels gradually drift out of balance. Rebalancing shifts sats back around through a circular payment, restoring room on both sides so traffic keeps flowing.
Check your gauges on a steady rhythm and rebalance when a channel gets lopsided. Small regular tune ups keep everything humming and cost less than big occasional ones.
06Watching your numbers
Keep an honest scorecard: forwarded volume, fees earned, and the onchain costs of opening channels and rebalancing. Compare what came in against what went out, and the picture stays clear.
Small home nodes earn small steady sats, and patience plus smart placement grow that over time. Large well connected nodes with deep channels earn the most, which rewards anyone who builds thoughtfully. Your node becomes a tiny toll booth on the fastest payment network on earth: start small, learn the flow, and let the sats find you.
01What is a Lightning routing node?
A node with open payment channels that forwards other people's Lightning payments along their route. Each forwarded payment pays your node a tiny fee, so a well connected node collects a steady stream of sats for keeping traffic moving.
02How do routing fees work?
You set two values: a small flat base fee per forwarded payment, and a proportional rate in parts per million, or ppm. A payment passing through your channel pays the base fee plus the ppm rate on its amount, and both land in your node.
03How much can a small routing node earn?
Modest amounts at first, growing with channel size and placement. Small home nodes collect a pleasant trickle of sats, and larger well connected nodes with deep channels earn noticeably more. Thoughtful placement beats raw size.
04What does it cost to run a routing node?
The main costs are the onchain fees for opening channels, a little electricity for the machine that stays awake, and the small fees for rebalancing. Many runners use a low power home computer, so the monthly spend stays light.
05Does my node have to stay online all the time?
Lightning can only route through nodes that are awake, so the more time your node spends online, the more payments find it. Most routing runners keep a small home computer on around the clock, which suits the job beautifully.
