The partnership pairs Bitcoin settlement with FedNow plumbing.
Lightspark, a Bitcoin Lightning Network startup founded by former Meta executive David Marcus, who oversaw the development of Meta’s Libra token, is pushing the idea of using BTC for everyday payments rather than long-term holding.
In a Wednesday announcement, Feb. 18, Lightspark said it had teamed up with Cross River Bank, a crypto-friendly, FDIC-insured bank, to support 24/7 settlement of Bitcoin network transactions through the U.S. banking system.
Cross River has become a key banking partner for crypto firms in the U.S., providing banking services to companies such as Circle, Coinbase and others, particularly across cards and stablecoin-linked programs.
Under the arrangement, Lightspark processes transactions on the Lightning Network, while Cross River settles the fiat legs via faster payment systems such as FedNow. The announcement says the collaboration targets B2B, cross-border and retail flows where immediate settlement materially changes cash management.
Usage Outpaces TVL
Lightning Network has had a strong but uneven run so far. Total network capacity climbed to new highs in late 2025 before easing slightly in mid-February of this year, while data from DefiLlama shows that total value locked stands near $338 million, a figure likely influenced by Bitcoin’s recent price pullback.

Still, Wouters noted that today the “most common use case for Lightning transactions is sending funds from and to exchanges,” highlighting how far the network still has to go as a retail payments rail.
