Stablecoins have been hailed as the simple solution to crypto payments, but the reality is far more complex. While they solved the problem of volatility, they didn't address the underlying issue of payment rails. Every stablecoin is now essentially a different stablecoin, with varying networks, addresses, fees, and liquidity. This creates a confusing and frustrating experience for merchants and customers alike. The 'Which USDT?' question is a common one, and it highlights the need for better routing and clearer states in payment systems. Stablecoins fixed the obvious problem, but they didn't make the payment rail simple. Now, it's time for routing to become the real product, not just a QR code or a payment link. The checkout should meet the customer closer to where they already are, and the merchant should receive the asset and chain they actually want. Direct settlement still matters, and the goal is to let customers pay flexibly while confirmed value settles directly to the merchant wallet, without platform custody becoming the normal flow. Stablecoins made crypto useful, but routing will make it usable. The winner will be the checkout that makes the wrong-chain problem feel rare, visible, and recoverable. It's time to stop pretending the customer will always arrive with the perfect asset on the perfect network and embrace the complexity of payment rails.
