Overview
A payment rail is the infrastructure through which payments are transmitted and settled. Blockchains and stablecoins are emerging payment rails. They enable fast, global transfers.
How It Works
Payment rails move value between parties and settle balances. Traditional rails include banks and card networks; crypto rails use blockchains and stablecoins. Each has different cost and speed.
Why It Matters
Crypto payment rails offer 24/7, low-cost, borderless transfers. They compete with and complement traditional systems. They are a key use case for blockchain adoption.
