Cash App users can now send and receive USDC directly within the mobile payment platform across Solana, Ethereum, Polygon, and Arbitrum. According to Block Bitcoin Product Lead Miles Suter, the feature works through users' existing USD balances without additional wallet setup or transfer fees.
Stablecoins as a Bridge Between Fiat and Bitcoin
Suter shared the update on social media Wednesday, outlining Block's broader digital payment strategy. He explained that stablecoins serve as a bridge between traditional fiat systems and Bitcoin-based financial services. Despite adding USDC support, Suter stressed that Bitcoin remains the company's primary long-term objective, calling it "Money 2.0" while viewing stablecoins as transitional payment tools.
Cash App currently reaches nearly 59 million monthly active users. This multi-chain integration could introduce stablecoin transfers to a significantly larger mainstream audience. Block previously limited most crypto services to Bitcoin products, but now expands into stablecoins while maintaining its Bitcoin-focused projects like Bitkey, Proto, and the open-source unit Spiral.
Payment Giants Race Into Stablecoin Infrastructure
Visa and Mastercard continue expanding stablecoin-related settlement services, while banks and fintech firms increase blockchain payment experiments. The total stablecoin supply has surpassed $300 billion. Tether's USDT added more than $5 billion in supply over one month, while the combined supply of USDC, Ethena's USDe, and PayPal's PYUSD declined by roughly $4.2 billion.
Circle remains the largest U.S.-based stablecoin issuer, with USDC widely used for blockchain payments and DeFi activity. Cash App's multi-chain USDC feature illustrates how stablecoins increasingly complement existing cryptocurrency ecosystems rather than replace them. Block's move signals intensifying competition among fintech companies building blockchain payment services for retail users, leveraging stablecoins' faster transfers and lower settlement costs.
