Lightning Network Capacity Retreats From Record as USDT Goes Live
Bitcoin's Lightning Network hit a record 5,600 BTC in public capacity even as BTC trades near $59,000. Stablecoins, exchange tie-ins and BOLT12 upgrades are reshaping the payment layer.
August 2026 update: Lightning’s public capacity has cooled from its December 2025 all-time high of 5,637 BTC to about 2,640 BTC — roughly $168 million — as of August 2026, with live 1ML dashboards showing readings between 2,642 and 2,646 BTC and a decline of a few percent over the past 30 days. The stablecoin story has moved the other way, from promise to production: Tether CEO Paolo Ardoino confirmed in March 2026 that USDT is live on Lightning via Taproot Assets. Capacity figures, dates and the headline throughout have been updated to reflect this.
Bitcoin’s Lightning Network is moving through one of its most consequential stretches since launch, and capacity tells a more complicated story than it did a year ago. Public channels reached an all-time high of 5,637 BTC in December 2025 and held above 5,600 BTC through the spring, worth roughly $330 million at a spot price near $59,000 on June 26, 2026. Since then the public graph has cooled sharply: live data from 1ML now puts capacity at about 2,640 BTC, or roughly $168 million, down about 3.6% over the past 30 days. Bitcoin itself has spent much of 2026 well below where it traded a year earlier, according to CoinDesk pricing.
The split still tells a story. Spot prices have cooled and the public payment layer has given back much of its record, yet the plumbing that moves Bitcoin for payments has kept maturing where it counts. Stablecoins have arrived on Lightning rails, exchanges have wired in deposits and withdrawals, and a long awaited batch of protocol upgrades now ships by default. Here is where the network stands as 2026 enters its second half, and what readers in the United States should watch now that Washington’s stablecoin rulebook has hit its statutory deadline.
A capacity record, then a pullback
Capacity measures the amount of Bitcoin locked inside payment channels, and it is the cleanest proxy for how much value the network can route at once. Public capacity set a record of 5,637 BTC on December 16, 2025, a peak flagged in coverage from Bitcoin Magazine, and it stayed above 5,600 BTC through the spring, a level tracked by network monitors including Bitcoin Visuals. That surge coincided with fresh money flowing into the ecosystem; a day before the record print, Tether disclosed an $8 million investment in Speed, a Lightning-focused startup. Since the spring, though, the public graph has retreated to about 2,640 BTC, worth roughly $168 million, with 1ML’s live dashboards showing readings between 2,642 and 2,646 BTC and a decline of a few percent over the past month. Public node counts have settled near 17,000, while the tally of active channels remains above 75,000. Crucially, the cost of using all of this stayed low; a typical Lightning payment still clears for a fraction of a cent, regardless of size.
Those public figures understate the real footprint. A growing share of liquidity now sits in private channels run by exchanges, custodians and mobile wallet providers that do not advertise to the wider graph. Industry estimates have long put total capacity, public and private combined, at several times the public reading. Just as telling, routed value jumped sharply over the past year while the raw number of payments fell, a sign that bigger, higher value transfers are replacing the early flood of tiny tips. For context, an equivalent base-chain Bitcoin payment can cost more than a dollar and wait for the next block, which is why high-frequency, low-value flows keep migrating onto channels in the first place. The table below summarizes the headline metrics.
| Metric | August 2026 reading | Context |
|---|---|---|
| Public capacity | About 2,640 BTC (around $168M) | Down from Dec 2025 record of 5,637 BTC |
| Public nodes | About 17,000 | Little changed after years of growth |
| Active channels | Above 75,000 | Fewer, larger channels |
| Estimated total capacity | Several times the public figure | Includes private channels |
| Value routed (Nov 2025 reference) | Around $1.17B | Single-month figure |
Why bigger channels, and fewer of them
The shape of the network has changed as much as its size. Lightning began as a sprawling mesh of hobbyist nodes; it now leans toward a hub-and-spoke layout, where a smaller set of well capitalized routing nodes carries most of the traffic. That concentration is the direct cause of the volume-up, count-down pattern: professional operators move large sums between each other, and consumer activity increasingly hides behind custodial wallets that net out many small payments into a few big channel updates.
The trade-off cuts both ways. Larger hubs improve routing success and lower the odds that a payment fails for lack of liquidity, which matters for any merchant taking real orders. The cost is a more centralized topology, with exchanges and dedicated infrastructure firms holding an outsized slice of the network’s funds. Decentralization purists are uneasy about a few large nodes sitting at the center of the graph; payment businesses, which care about reliability first, are not complaining. The open question is whether the new tooling described below can hand smaller operators a way back in.
Upgrades leave the lab: BOLT12, splicing and async payments
The technical story this cycle is about upgrades leaving the experimental column. BOLT12, the long developed standard for reusable payment “offers,” was merged into the official Lightning specification in a milestone pull request, #798 in the lightning/bolts repository, the first new BOLT added since 2017. Offers replace one-time invoices with static, reusable codes that support recurring payments and stronger privacy through onion messaging, as documented by Bitcoin Optech. In plain terms, a business can publish a single permanent payment code instead of generating a fresh invoice for every sale.
Core Lightning now enables offers by default, and competing implementations are catching up at their own pace, with rival node software treating the feature as opt-in for the moment. Two other features round out the upgrade: channel splicing, which lets a node add or remove funds without closing and reopening a channel, and async payments, specified in pull request #1149, which let a sender push funds that an offline mobile wallet can claim once it reconnects. Together they target Lightning’s two oldest complaints, rigid liquidity and the need for both parties to be online at the same moment. For routing nodes, splicing may be the bigger quality-of-life change, since it lets an operator move capital into a busy channel on the fly instead of locking funds in a fixed position for the life of that channel. Async payments, in turn, matter most for phones, which spend much of the day offline.
Dollars on Bitcoin: stablecoins via Taproot Assets
The biggest change to what Lightning can carry is the arrival of dollars, and over the past year it has gone from pitch to production. Through the Taproot Assets protocol built by Lightning Labs, issuers can mint tokens that inherit Bitcoin’s security model and settle over Lightning channels. In March 2026, Tether CEO Paolo Ardoino confirmed that USDT had gone live on the Lightning Network through Taproot Assets, capping a build that began at the Plan B Forum in El Salvador on January 30, 2025. Tether framed the move as opening instant, dollar denominated payments on Bitcoin, per the company’s own newsroom. With a global stablecoin market now well above $300 billion, the prospect of moving those dollars at Lightning speed is a serious draw.
Lightning Labs has kept iterating, shipping releases aimed squarely at smoother stablecoin settlement, as reported by The Block. The pitch is straightforward: a merchant or worker can hold a dollar balance, send it for a fraction of a cent, and convert to or from Bitcoin at the edges without leaving the network. For users in high inflation economies, a stable unit of account that moves at Lightning speed is a far easier sell than price-volatile BTC, and it lets the same channels carry both money and the asset that secures them. Competing dollar tokens and a handful of regional stablecoins are lining up to use the same protocol, which would turn Lightning into a settlement layer for several currencies at once rather than Bitcoin alone. For a merchant, that means one integration can accept both BTC and dollars.
Exchanges and apps become the on-ramps
Distribution is following the technology. Coinbase, the largest US exchange, switched on Lightning deposits and withdrawals through a partnership with infrastructure firm Lightspark, charging a 0.1% fee on sends and capping early withdrawals while it tuned routing, as The Block detailed. Chief executive Brian Armstrong had called the integration “non-trivial, but worth doing,” a fair description of the liquidity management an exchange takes on when it runs Lightning for millions of customers.
Coinbase is not alone. Strike built its remittance business on Lightning, Cash App reported a sharp jump in Lightning usage, and Kraken and other venues added support for instant Bitcoin transfers. Most chose a custodial model, where the platform manages channels on a customer’s behalf so the user never has to run a node or think about liquidity. That convenience is what pulled Lightning into the mainstream, even as it deepened the custodial concentration noted earlier. Non-custodial options have not vanished, either; mobile wallets such as Phoenix and Breez still let users hold their own keys while leaning on service providers for inbound liquidity, a middle path between running a full node and trusting an exchange. The table below sketches the main approaches.
| Platform | Model | Notable detail |
|---|---|---|
| Coinbase | Custodial, via Lightspark | 0.1% send fee; phased rollout |
| Strike | Lightning-native payments | Cross-border remittances at its core |
| Cash App | Custodial | Large year-over-year Lightning growth |
| Kraken | Custodial deposits and withdrawals | Instant BTC transfers |
Remittances remain the proof point
If Lightning has a killer use case today, it is cross-border money movement. In El Salvador, the government’s Chivo wallet processed millions of Lightning transactions last year, and crypto remittances into the country reached $17.38 million in the first quarter of 2026, according to Bitcoin.com News. That is still a sliver, under 1%, of the roughly $2.4 billion in total remittances El Salvador receives each quarter, a reminder that adoption curves bend slowly even where a government is pushing them. Even so, the direction of travel is clear, with quarterly volumes climbing as wallets strip away the friction of receiving a Lightning payment.
Africa shows a steeper slope. Providers are using Lightning to move value between Europe and the continent in seconds, with firms processing Lightning-based payouts across more than 20 countries and reporting triple-digit annual growth, a trend documented by Nasdaq. Where the alternative is a multi-day wire and a double-digit percentage fee, a settlement that clears for cents in seconds is an obvious upgrade, and it explains why payroll and remittance startups have become some of Lightning’s heaviest users.
Washington’s rulebook and the SEC line
The stablecoin wave running over Lightning collides with a US regulatory framework that is still being written. The GENIUS Act, signed into law in 2025, set a federal regime for payment stablecoins and gave agencies until July 2026 to finalize implementing rules, a deadline that has now arrived; the bill text is public on Congress.gov. One feature matters for anyone routing dollars on Bitcoin: the law treats compliant payment stablecoins as payment instruments rather than securities, which keeps them outside the Securities and Exchange Commission’s jurisdiction even as the SEC presses its case on other tokens.
The catch is issuer eligibility. Tether’s USDT is issued offshore and is not a permitted US issuer under the statute, so the company stood up a separate, US-regulated dollar token, issued through a chartered US bank partner, to serve American customers while it waits on a Treasury reciprocity determination. For Lightning, the upshot is a two-track world: globally, USDT can move freely over Taproot Assets; inside the US perimeter, the compliant token a platform is allowed to offer may differ. Builders targeting American users will need to track exactly which dollar they are routing.
What to watch in the second half of 2026
Three threads will define the rest of the year. First, whether public capacity stabilizes or keeps sliding from its December record, and whether private capacity keeps outrunning the public graph, which would make headline capacity numbers an ever weaker gauge of real activity. Second, how quickly offers, splicing and async payments propagate across wallets, since defaults, not specifications, are where adoption actually happens. Third, how Washington implements the GENIUS Act now that its July rulemaking deadline has passed, which will decide which stablecoins US platforms can put on Lightning rails and on what terms.
For now, the contrast holds. Bitcoin’s price is well off its highs, and its public payment layer has given back much of the capacity it set as a record late last year, but that layer now carries dollars as well as bitcoin and settles both for a fraction of a cent. If the payments thesis for Bitcoin is going to be proven, this is the layer that will have to do it.
