Argues that blockchains handle settlement but not authorization and clearing, and proposes WalletConnect’s universal connection layer that routes across wallets, tokens and chains and exposes a payment request with preauthorization so merchants avoid handling dozens of stablecoin formats. Claims: card settlement can take up to 7 days while stablecoin settlement is 10–20 seconds, card fees reach ~3% versus lower crypto fees, WalletConnect’s eight‑year QR network and SDKs let users pay with any wallet without a new app, and merchants receive local currency and fewer chargebacks.
