🚀 Big news 🚀 @coinbase and @cloudflare will be launching the x402 Foundation to establish x402 as the universal standard for AI-driven payments. Legacy payment systems weren’t built for machines, but x402 changes that by embedding payments directly into web interactions, enabling AI agents, APIs, and apps to transact value as easily as they exchange data. This is a generational moment for payments. With the x402 Foundation, we’ll help build the infrastructure for an open economy where agents and people can transact seamlessly.

Huge shoutout to @GainsleyJustin who helped get USDC payments added to my @Shopify via shopify payments store at alchemymerch.com I'd been asking Shopify Plus about it for over a month!

Payments are just so much better with stablecoins. Thrilled to partner with @Shopify to introduce this to 1M+ businesses around the world. Merchants get fast payments, lower fees, and much less friction when paid with USDC, especially across borders.
.@harleyf (President @shopify) on the company's approach to stablecoins: "USDC just gives merchants more choices, more security, and offers much faster settlement." "With stablecoins, offering a payment method that combines the transparency of blockchain with the speed and price stability of a major currency is really valuable." "Merchants get paid in dollars, there's no new wallet, there's no added friction and it's just a seamless, flexible, safe transaction. It's about utility, not speculation."

Cross-border commerce shouldn’t be complicated. With USDC and @coinbase, Shopify merchants get paid faster and safer. No new wallet. No added friction. Just utility. Thanks for the chat @TBPN.

USDC payments are now rolling out across Shopify. Tens of thousands of merchants going live, with instant, borderless payments built directly into @Shopify Payments. Most people won’t even realize they’re using @base. They’ll just feel faster, cheaper, smoother checkout. That’s the unlock. Shopify gets the UX edge. Base becomes the onchain backbone of global commerce. Everyone else will have no choice but to follow. You’re still not bullish enough. This is how it starts. This is how it scales. This is how we bring the world onchain.
USDC payments are now rolling out to tens of thousands of Shopify merchants. Borderless, global, low-cost payments with zero integration complexity. Want access for your store? DM me.

I'm hiring! Come build the future of crypto on Coinbase One, the best consumer crypto membership! I'm looking for a customer obsessed, ownership minded PM2 to come build innovative new value for our users. Apply here: coinbase.com/careers/positio…
We're living in pretty crazy times. I saw the Base Pay announcement today, installed @cursor_ai, pointed it at the @base dev docs, and 1-shotted a checkout app that sells $1 hugs in <5 minutes. USDC goes straight into my @CoinbaseBiz account where its earning 4.1% APY and can be cashed out to a bank whenever I want it. Internet money is just better.
Accept USDC with Base Pay. Manage it all with Coinbase Business.
