And there I am, a VC happy hour in Soma. I order a drink at the bar and pay with my Apple card. I turn around and joke to a man in a Patagonia vest that all starts are bundling, unbundling, or ISAs. He pats me on the should and says "let me know how I can be helpful"

x402 is an open standard for internet native payments, regardless of asset or network. Its core to the principals of x402. A huge shoutout to @SolanaFndn and @notorious_d_e_v working with us on a thoughtful Solana implementation!

After 6 months of real world x402 adoption, we're starting to plan v2. We've learned a ton and received amazing feedback from builders across the community that inspired the proposed v2. For your review: github.com/coinbase/x402/…
