Shift4 has introduced stablecoin settlement for merchants, facilitating cryptocurrency payments through networks including Polygon, Ethereum, Solana, Stellar, TON, Plasma, and Base. This new service allows businesses to bypass traditional bank transfers, offering 24/7 operations that eliminate delays typically experienced during weekends and holidays. By adopting crypto settlement, merchants can achieve faster liquidity across different time zones and reduce costs associated with correspondent banking, as funds are received directly on-chain without the need for traditional financial intermediaries.
