Bitcoin’s Lightning Network has reached a new all-time high in capacity, signaling renewed momentum for the layer-2 payments network after a long period of stagnation. The increase is being driven largely by growing adoption from major crypto exchanges and new technical upgrades that expand Lightning’s functionality.
On Monday, Lightning Network capacity climbed to 5,606 BTC, surpassing its previous record set in March 2023, according to Bitcoin Visuals. Analytics platform Amboss reported an even higher peak of 5,637 BTC a day later, representing roughly $490 million locked into the network.
The surge followed a sharp increase in November and December, reversing much of the decline seen earlier in the year. More Bitcoin is being committed to Lightning channels, allowing faster and cheaper transactions across the network.
Despite the rise in capacity, usage metrics show a more mixed picture. The number of Lightning nodes currently stands at 14,940, down from a peak of more than 20,700 in early 2022. The total number of payment channels has also declined to 48,678, well below its 2022 high. The data suggests Bitcoin holders are adding more funds to existing infrastructure rather than spinning up new nodes.
Amboss said the capacity growth is being driven by multiple large players, not a single outlier. The platform noted that major exchanges, including Binance and OKX, have added significant amounts of Bitcoin to Lightning this month, helping push capacity to record levels.
Broader industry support is also expanding Lightning’s reach. On Tuesday, stablecoin issuer Tether led an $8 million funding round for Bitcoin payments startup Speed, which is building stablecoin payment tools on the Lightning Network. The move highlights growing interest in using Lightning beyond pure Bitcoin transactions.
Meanwhile, MetaMask rolled out Bitcoin support this week, though it confirmed transactions will use Native SegWit rather than Lightning. While not a direct Lightning integration, the move reflects increasing demand for Bitcoin-native functionality across major wallets.
Technical upgrades are also strengthening Lightning’s long-term outlook. Lightning Labs announced the release of Taproot Assets v0.7, a major update to its multi-asset protocol built on Bitcoin and Lightning. The upgrade introduces reusable addresses, fully auditable asset supplies, and support for larger, more reliable transactions.
Taproot Assets allows assets such as stablecoins to be issued on Bitcoin and transferred instantly over Lightning. The new auditability feature improves transparency without relying on trust, a key requirement for institutional adoption.
Lightning Labs said the update lays the groundwork for Bitcoin and Lightning to evolve into a multi-asset network capable of supporting massive transaction volumes. With exchange adoption rising and new infrastructure coming online, Lightning’s record capacity may signal a broader shift in how Bitcoin is used for real-world payments.
