Lightning Network capacity hits new ATH as exchanges lead adoption

Lightning Network capacity hit a new ATH of 5,606 BTC worth ~$500 million as exchanges increase crypto adoption, with Amboss reporting a peak of 5,637 BTC. Lightning channel and node counts remained below 2022 highs despite the surge in capacity and a new Taproot Assets update to enable multi-asset transactions.

Lightning Labs claims that the Taproot Assets upgrade to v0.7 added reusable addresses and an auditable supply feature for multi-asset transfers over the Lightning Network. Data from Bitcoin Visuals shows that the new Lightning Network capacity reached on Monday surpassed the previous record set in March 2023. 

Meanwhile, Amboss separately valued the network’s capacity at roughly $490 million. The Lightning Network capacity’s surge follows a sharp rise in November and December after a year of declines, as payment channels received more Bitcoin.

Amboss also said the capacity increase suggests broader participation rather than a single large contributor. 

Channels and nodes remain below 2022 peaks

According to Lightning Labs, node and channel counts have remained well below previous highs despite the capacity increase. Lightning nodes stand at 14,940, a significant drop from the peak of 20,700 back in March 2022. The channels were at 48,678, which is also below the 2022 peak. 

Amboss also noted that large exchanges, including OKX and Binance, deposited a larger amount of BTC into Lightning this month.

On the other hand, Lightning Labs stated that the release of Taproot Assets v0.7, a multi-asset Lightning protocol, laid the foundation for trillions of dollars to flow into Bitcoin via Lightning. The protocol is also designed to allow assets such as stablecoins to be minted on Bitcoin and sent over Lightning. 

Meanwhile, stablecoin issuer Tether announced on December 16 that it had led an $8 million funding round in Bitcoin startup Speed to enable Lightning Network stablecoin payments. MetaMask also added Bitcoin support this week, although it clarified that its transactions would use the Native SegWit derivation path, not the Lightning Network. 

On the other hand, Amboss says each Lightning node has a unique view of the network based on the gossip information it receives. The sources of data maintain separate policies of what constitutes network capacity based on its activity or status, among other considerations.  

Taproot Assets enables stablecoins to leverage Bitcoin’s security

Taproot Assets reportedly enables stablecoins to leverage Bitcoin’s security, while achieving near-instant, low-fee transfers through the Lightning Network. The new auditable supply feature upgrade ensures transparency without requiring trust, according to Lightning Labs.

Lightning Labs CEO Elizabeth Stark said the integration combines the security of Bitcoin with the speed and scalability of the Lightning Network. 

Meanwhile, developers are also addressing issues affecting channel health and payment reliability at a structural level. Research on replacement cycling vulnerabilities and jamming attacks continues through the Bitcoin Optech working groups. Features like liquidity automation tooling and BOLT12 Offers are making Lightning stronger for commercial usage. 

Application layers using the Lightning protocol are also on the rise, with the L402 specification now deployed in early AI agent stacks, such as LangChainBitcoin. The L402 specification enables pay-per-request APIs using Lightning-native authentication and micropayments. 

The design reportedly enables automated agents to pay per API response or inference call without requiring static keys or fiat accounts. However, the shifts in protocols and use cases provide context for why public capacity alone cannot be a reliable indicator of the Lightning Network’s adoption trajectory. Meanwhile, developers argue that Lightning’s evolution is more about increasing the utility of each Satoshi already in supply and less about growing visible liquidity.
