Bitcoin Lightning Network Capacity Doubles in 3 Months as Strike and Cash App Drive Adoption

The Bitcoin Lightning Network has quietly reached a new milestone, with total network capacity surpassing 12,000 BTC — roughly $1.1 billion at current prices — according to data from Amboss and 1ML. The figure represents a doubling since December 2025 and marks the fastest period of growth in the network's history.

What Is Driving the Surge

Three factors converge behind the acceleration. First, Strike expanded its Lightning-powered remittance service to 15 new countries in January, including Nigeria, the Philippines, and Colombia. These corridors represent some of the highest-volume remittance routes in the world, and Strike's near-zero fees have undercut incumbents like Western Union and MoneyGram by significant margins.

Second, Block's Cash App — which integrated Lightning payments in 2023 — rolled out a feature allowing users to pay any Lightning invoice directly from their dollar balance. The update removed the requirement to hold Bitcoin, effectively turning Cash App into a Lightning gateway for its 57 million monthly active users.

Third, infrastructure improvements have made running Lightning nodes substantially easier. The release of LDK (Lightning Development Kit) version 3.0 in February brought simplified channel management, automated liquidity balancing, and native support for async payments — a feature that allows users to receive Lightning payments even when their wallet is offline.

Merchants Are Finally On Board

For years, Lightning adoption was hampered by a chicken-and-egg problem: merchants would not accept Lightning because few customers used it, and customers had no reason to use it because few merchants accepted it. That dynamic is shifting.

Shopify announced in February that its Lightning payment plugin, developed in partnership with Voltage, has been activated by over 40,000 stores. The plugin converts Lightning payments to local currency instantly, so merchants bear no Bitcoin price exposure. Transaction fees are fixed at 0.5 percent — well below the 2.9 percent charged by credit card processors.

"Lightning is not competing with Bitcoin as a store of value," said Jack Mallers, Strike's CEO, during a recent podcast appearance. "It's competing with Visa and Mastercard as a payment rail. And on speed and cost, it wins every time."

In El Salvador, where Bitcoin has been legal tender since 2021, Lightning transactions now account for an estimated 30 percent of digital payments. The government's Chivo wallet processed over 5 million Lightning transactions in January, with an average value of $8.40 — suggesting the network is being used for everyday purchases rather than speculation.

Technical Improvements Under the Hood

The Lightning Network's growth is not just about capacity. Recent protocol upgrades have addressed long-standing concerns about reliability and privacy.

Taproot channels, which became widely supported in late 2025, make Lightning transactions indistinguishable from regular Bitcoin transactions on the base layer. This improves privacy and reduces the on-chain footprint of channel openings and closings.

Splicing — the ability to add or remove funds from a Lightning channel without closing it — has been rolled out across major implementations including LND, CLN, and Eclair. The feature eliminates one of the most frustrating user experience issues, where channels had to be closed and reopened to adjust capacity.

Path reliability has also improved significantly. According to data from Terminal Web, the success rate for Lightning payments under $100 now exceeds 99 percent, up from roughly 95 percent a year ago. For larger payments above $1,000, the success rate sits at 97 percent, a figure that would have been unthinkable in the network's early days.

Challenges and Competition

Lightning is not without its critics. Some argue that the network's reliance on channel liquidity creates centralization risks, with a handful of large routing nodes handling a disproportionate share of traffic. Others point to competition from stablecoin payment networks on chains like Tron and Solana, which offer similar speed and cost advantages without Bitcoin's price volatility.

There is also the question of regulatory treatment. As Lightning increasingly functions as a payment network rather than a peer-to-peer transfer mechanism, regulators may impose know-your-customer requirements on node operators — a move that could undermine the network's permissionless nature.

For now, though, the numbers speak for themselves. Lightning is processing more transactions, holding more value, and reaching more users than at any point in its history. The question is no longer whether Lightning works, but whether it can scale fast enough to capture a meaningful share of global payments.
