**[Analysis: Stablecoins Still Primarily Used for Crypto Trading, Payment Applications Yet to Break Through]** Deep Tide TechFlow reports, on April 13, the latest analysis from the Kansas City Federal Reserve indicates that stablecoins are currently mainly utilized for cryptocurrency trading and liquidity support within the financial ecosystem, and have yet to become a mainstream payment method. The report shows that approximately 49% of stablecoin supply is used for trading liquidity in centralized exchanges, decentralized finance (DeFi) protocols, and broader crypto infrastructure; 29% is used for wallet-to-wallet transfers or internal fund operations; 21% remains idle; and less than 1% is actually used for real-world payments. The report suggests that stablecoins, designed as native tools for the crypto ecosystem, are limited by cross-chain interoperability and their connection to traditional financial systems, preventing them from achieving large-scale payment applications. Although payment processors like Mastercard and Visa have announced support for related technologies by 2026, stablecoin payment use cases remain in their early stages. Future development will require addressing key issues such as interoperability, compliance, and identity verification.
