Payment Rails
Infrastructure for processing and settling digital asset transactions.
What is Payment Rails?
Payment rails refer to the underlying systems or networks that facilitate the transfer and settlement of digital assets or fiat payments. In the x402 protocol, payment rails can include blockchain networks (e.g., Base blockchain for stablecoins) or traditional financial systems (e.g., credit cards). The protocol’s flexibility allows servers to support multiple rails, enabling seamless transactions for use cases like deferred payments or batch settlements in pay-per-crawl scenarios.
