Stablecoin Payment Rails Becoming Increasingly Important

The cryptocurrency market is witnessing a shift towards payment-focused blockchains as stablecoin issuers and fintech companies seek to control the settlement infrastructure behind US digital-dollar transfers.

Delphi Digital notes that some stablecoin issuers are building new blockchain networks designed for institutional payment flows rather than broader token issuance and smart-contract activity. For instance, Tether-backed Plasma launched on mainnet in September 2025 after raising $24 million in February.

Circle also launched the public testnet for Arc, an open L1 blockchain purpose-built for stablecoin finance. This development adds to signs of a structural shift from generic blockchain infrastructure toward payment-focused networks, as companies compete to control the rails underpinning stablecoin settlement.
