Lightning channel liquidity is the bitcoin available to send or receive through a channel in a particular direction. Total capacity sets the channel’s overall limit, but doesn’t show whether a specific payment or route has enough balance.
A Lightning channel holds bitcoin shared between two participants. The balance on each side determines who can send or receive. Payments shift that balance, so usable liquidity depends on direction and every channel along a route, not just the network’s total capacity.
LND’s guide describes a channel as bitcoin locked by a transaction in a 2-of-2 contract. Total capacity is the combined amount in the channel, not necessarily what either participant can send at a given moment.
For example, LND describes a 1,000,000-sat channel funded entirely by Alice. At opening, Alice can send the funds through the channel, while the other participant can receive them. As payments move funds across, the available amounts in each direction change.
A payment moves balance from one side of a channel to the other.
Capacity is the size of the container; liquidity is the balance available on the side and in the direction a payment needs. A capacity total or average can’t show by itself how readily a payment can route.
Term What it describes What it doesn’t tell you Total channel capacity All bitcoin locked in a channel How much either side can send now Outbound liquidity Amount a node can send through a channel Whether the full route has enough balance Inbound liquidity Amount a node can receive through a channel Whether other hops can carry the payment Public capacity total Visible capacity across public channels Private channels, balance splits, or payment volumeThese dated figures measure capacity, not ready-to-use funds. 21Shares, citing Glassnode data, reported public Lightning channel capacity of 3,767 BTC on September 30, 2026, down 19.3% quarter over quarter. CoinGlass reported average public channel capacity of 0.087623 BTC on October 29, 2026. Neither figure reveals directional balance for an individual payment. Lightning channel liquidity is local and route-specific, not a network-wide reserve number.
Bitcoin’s market value can change independently of a channel’s directional balance. Market value and payment capacity are separate measures.
A route can depend on available balance across more than one channel.
Liquidity management involves a trade-off: funds positioned to receive payments aren’t simultaneously available for the same node to send through that channel. Lightning Terminal describes Lightning Pool as a non-custodial, peer-to-peer marketplace where operators can buy inbound liquidity or sell liquidity by opening channels for others. It offers a way to buy liquidity, but doesn’t ensure a particular route will work.
Channel funds and payment routing require careful operational management.
It’s the bitcoin available to send or receive through a Lightning channel in a particular direction. It changes as payments shift balances between participants.
Capacity is the total locked in a channel, not necessarily the amount available on the sending side. A route also needs enough directional balance at every hop, according to CoinGlass.
Sending payments through a channel shifts balance from the node’s local side to its remote side, creating inbound capacity. Lightning Pool lets operators buy inbound liquidity. LND also describes Loop Out and Loop In for moving funds between a channel and an on-chain address; availability depends on the channel and node setup.
