Cash App Adds USDC on Four Blockchains as Block Expands Crypto Payments

• Cash App enabled USDC transfers across Solana, Ethereum, Polygon, and Arbitrum blockchains.
• Miles Suter said stablecoins bridge traditional finance systems with Bitcoin infrastructure.
• Visa and Mastercard continue expanding stablecoin services as market competition intensifies globally.

Cash App users can now send and receive USDC across Solana, Ethereum, Polygon, and Arbitrum directly within the mobile payment platform. According to Block Bitcoin Product Lead Miles Suter, the feature works through users’ existing USD balances without extra wallet setup or transfer fees. Suter shared the update through social media on Wednesday while outlining Block’s broader approach toward digital payments. He explained that stablecoins serve as a bridge between traditional fiat systems and Bitcoin-based financial services.

The expansion marks a major shift for Block, Inc., which traditionally limited most crypto services to Bitcoin products. The company operates Cash App alongside Bitcoin-focused projects including Bitkey, Proto, and the open-source development unit Spiral.

According to company data, Cash App currently reaches nearly 59 million monthly active users. Consequently, the latest integration could introduce stablecoin transfers to a significantly larger mainstream audience. Moreover, the rollout places Cash App among several financial companies increasing their involvement in blockchain-based payment systems. Stablecoins continue gaining traction among payment firms because they support faster transfers and lower settlement costs.

Block Maintains Bitcoin Vision Despite Stablecoin Expansion

Despite adding support for USDC transfers, Suter stated that Bitcoin remains the company’s primary long-term objective. According to his social media post, Block still views Bitcoin as “Money 2.0” while stablecoins function as transitional payment tools. Meanwhile, Circle continues holding its position as the largest stablecoin issuer based in the United States. USDC also remains one of the most widely used stablecoins for blockchain payments and decentralized finance activity.

Additionally, major payment firms Visa and Mastercard continue expanding stablecoin-related infrastructure and settlement services. Banks and fintech companies also increased blockchain payment experiments throughout recent months. Recent market data showed the total stablecoin supply surpassed $300 billion. During the same period, Tether’s USDT added more than $5 billion in supply over one month. However, the combined supply of USDC, Ethena’s USDe, and PayPal’s PYUSD declined by roughly $4.2 billion.

Nevertheless, Block’s latest expansion signals continued competition among fintech companies building blockchain payment services for retail users. The move also demonstrates how stablecoins increasingly complement existing cryptocurrency ecosystems rather than replacing them entirely. In conclusion, Cash App’s multi-chain USDC integration highlights the growing role of stablecoins within mainstream payment applications while Block continues maintaining its broader Bitcoin-focused strategy.
