Cash App, the payments platform owned by Block, the financial technology company co-founded by Jack Dorsey, launched support for sending and receiving USDC on Wednesday, offering fee-free stablecoin transfers across four blockchain networks with no separate wallet or crypto setup required.

An individual familiar with the matter told CoinDesk the stablecoin feature was rolled out to 25% of users already and by the end of the week, all users will have access.

Block's Cash App is rolling out USDC stablecoin payments to 15 million users this week, with instant conversion to dollars via Solana blockchain rails.
