Open Payment Standard x402 Expands Capabilities in Major Upgrade

After six months of real-world usage, the open payment standard x402 has received a major update, extending the protocol beyond single-request, exact-amount payments. The release adds support for wallet-based identity, automatic API discovery, dynamic payment recipients, expanded multi-chain and fiat support via CAIP standards, and a fully modular SDK for custom networks and payment schemes.
