Cash App Lets Dollar Balances Pay Bitcoin Wallets via Lightning
Cash App has rolled out a feature that allows users to send their dollar cash balances straight to Bitcoin wallets using the Lightning Network, a Layer 2 scaling solution. Customers can effectively pay with their regular fiat balance while recipients receive Bitcoin over Lightning, combining familiar payment rails with faster, lower-cost BTC settlement.
The integration lowers a key barrier for merchant adoption by simplifying checkout and removing the need for customers to pre-purchase crypto. By bridging fiat balances and Lightning payments, Cash App may drive broader use of Layer 2 for commerce and remittances, increasing on‑ramp utility for Bitcoin. The change also raises operational questions for businesses around custody and settlement choices, but represents a notable step toward mainstream crypto payments.
