Late last year, Twitter CEO Jack Dorsey stepped down from his position in order to give his full attention to his other company, Square (now called Block), which had become increasingly invested in blockchain technology and cryptocurrency — just like Dorsey himself. Now we’re starting to see the results of Block’s embrace of crypto, as this morning Cash App announced it’s integrated with the Lightning Network, allowing its U.S. users to send bitcoin for free to anyone worldwide.
The feature had been slowly rolling out to Cash App customers before today, but Cash App had not yet made a formal announcement. The company says the rollout is expected to complete over the “coming weeks,” reaching all U.S. Cash App customers.
Once live, Cash App users will be able to send bitcoin internationally to any external compatible wallet, including those for family or friends or a self-managed wallet, like Chivo Wallet, BlueWallet or Muun Wallet, for example. Users will also be able to send bitcoin to any merchant that accepts Lightning Network payments, with zero fees. While this isn’t yet a mainstream activity, a few merchants have begun to accept Lightning payments, allowing customers to do things like order a pizza over the Lightning Network or buy gift cards.
The Lightning Network’s integration into Cash App could also help to empower the growing creator economy, as fans could send bitcoin to show their support for an individual creator or cause if they accepted Lightning payments.

Cash App explains the advantages of this system, noting that typical Bitcoin network transactions can take some time to process and see higher fees, compared with Lightning Network — whose name is meant to convey its speedier capabilities. Its transactions also take place independently of the blockchain (off-chain), which helps to reduce the fees, time and energy usage that would otherwise be involved. But the Lightning Network will still benefit from the blockchain’s technology and decentralization, as the transactions taking place on the network are later consolidated and recorded to the main Bitcoin blockchain.
Dorsey himself had demonstrated interest in the Lightning Network, tweeting back in 2019 that it was a “cool example” of the experimentation taking place among #BitcoinTwitter users. More recently, Block’s bitcoin-focused company, Spiral, presented its Lightning Development Kit (LDK), which offers a way to easily integrate bitcoin payments into any application. The new Lightning integration on Cash App is also powered by Spiral’s LDK — and Cash App is also the first and largest payments app to integrate with LDK at this time, the company notes.
The rollout of LDK is also an example of Block’s strategic vision in action, where one arm may build the tools that are adopted by other Block-owned businesses.
