[Cash App under Block rolls out USDC stablecoin payment functionality in phases, supporting Solana, Ethereum, Polygon, and Arbitrum chains] According to CoinDesk, Cash App under Block has begun rolling out USDC stablecoin payment functionality to approximately one-quarter of its nearly 60 million users, with plans to cover all users within the week. This feature allows users to deposit and withdraw USDC on Solana, Ethereum, Polygon, and Arbitrum chains, serving as a blockchain transfer channel for fiat balance rather than an investment tool. Product documentation indicates that on-chain transfers are irreversible, and funds will be permanently lost if sent to incorrect addresses or unsupported networks. The functionality is currently unavailable in New York State and for sponsored accounts. Verified users are subject to a daily sending limit of $2,000 (weekly limit of $5,000) and a weekly receiving limit of $10,000.
