Square, the payments platform operated by Block (founded by Jack Dorsey), is reporting 9.7% bitcoin yield on its bitcoin holdings by running a Lightning Network node.
The announcement was made by Miles Suter, Bitcoin product lead at Block, during the Bitcoin 2025 conference in Las Vegas. Suter explained that Square is earning “real bitcoin from our holdings” by efficiently routing payments across the Lightning Network.
Square’s yield comes from its role as a Lightning service provider, a business it launched two years ago to boost liquidity and efficiency on the Lightning Network. According to Lightning Labs’ Ryan Gentry, Square’s 9% yield could translate to roughly $1 million in annual revenue. 
The Lightning Network, a Bitcoin layer-2 protocol, has long been promoted as a solution to Bitcoin’s scalability and transaction speed issues. It enables micropayments and off-chain transactions, reducing congestion on the main blockchain. However, the network faces challenges, including the need for inbound liquidity—users must lock up BTC to receive BTC—potentially limiting participation by smaller nodes and raising concerns about decentralization.
Despite these hurdles, Square remains committed to advancing Bitcoin payments via Lightning. Suter revealed that 25% of Square’s outbound bitcoin transactions now use the Lightning Network. The company is actively testing Lightning-based payments at the Bitcoin 2025 event and plans to roll out the service to all eligible Square merchants by 2026.
Suter emphasized the transformative potential of Lightning:
“When you enable real payments by making them faster and more convenient, the network becomes stronger, smarter, and more beneficial. So if you’re questioning whether bitcoin is merely an asset, the response is no. It has already evolved into both an asset and a protocol, and now Block is spearheading the initiative to transform it into the world’s premier payment system.”
Square’s ongoing investment in Lightning signals its belief in Bitcoin’s future not just as a store of value, but as a global payments protocol.
