Today is 4.02 day. Less than a year ago (May 6, 2025), we published the x402 whitepaper. Since then, the protocol has: • Processed 166M+ transactions • Unlocked new monetization models for API, data, and other providers on the web. • Enabled autonomous flows that were difficult to support with traditional account infrastructure Today, we’re taking the next step. x402 is moving to @linuxfoundation, and we are launching x402 Foundation - with broad, cross-industry collaboration & input to steward an open, neutral standard for payments over HTTP. A big thank you to our amazing founding partners in this effort: @Adyen, @Awscloud , @AmericanExpress, @Ampersend_ai, @Circle, @Cloudflare, @Coinbase, @Fiserv, @Google, @KakaoPayCorp, @Mastercard, @merit_systems, @Microsoft, @Polygon, @PPRO_Payments, @Shopify, @SierraPlatform, @Solana , @Stripe, @Thirdweb, and @Visa. Enrollment for the foundation is open if you - or your company - is interested in participating, please reach out!

⚡️Solana delivers a full-stack ecosystem with high throughput, deep liquidity, and parallel execution across DeFi. Hyperliquid shines as a purpose-built trading appchain, but operates within a more limited scope and ecosystem depth. While #Hyperliquid is finely tuned for trading performance, #Solana offers a more scalable and versatile foundation for broader onchain use cases.
