Cash App launches USDC payments on Solana, Ethereum, Polygon and

Cash App has begun rolling out USDC stablecoin payments to roughly 25 % of its 59 million monthly users, with a plan to reach the full user base by the end of the week [2]. The feature lets customers send dollars from their Cash App balance to a blockchain address, where the amount is automatically converted to USDC on Solana, Ethereum, Polygon or Arbitrum, and then instantly swapped back to USD in the recipient’s Cash App account [1][4].

Users initiate a transfer by pasting a wallet address in the Payment tab and confirming the payment in dollars; receiving USDC works through a “Deposit USDC” option that generates a blockchain address, after which Cash App converts the incoming stablecoin to cash [1]. The rollout is fee‑free for a limited period to encourage adoption, but Block warns that blockchain transfers are irreversible and the service is unavailable in New York and for sponsored accounts [2]. Daily sending limits are capped at $2,000 (or $5,000 weekly) and weekly receiving caps sit at $10,000 [2].

Miles Suter, Block’s Bitcoin product lead, frames the move as a bridge between traditional fiat and “Money 2.0,” arguing that exposing millions of Cash App customers to open‑rail stablecoins will make them one step closer to Bitcoin [1][4]. The launch marks a notable shift for Block’s leadership, which has historically championed Bitcoin exclusively; CEO Jack Dorsey has publicly acknowledged customer demand for stablecoins despite his prior reservations [2][3].

By integrating USDC on multiple chains, Cash App becomes one of the largest consumer platforms to offer stablecoin payments, potentially accelerating mainstream adoption of blockchain‑based fiat transfers. The real test will be whether the fee‑free trial drives sustained usage and how the irreversible nature of blockchain transactions influences user behavior.
