The beauty of this being an open standard is that it will reach breakout velocity through rapid, widespread adoption
This will be a mega trend for 2026 https://t.co/kU0fJIPOsa pic.twitter.com/78e1fwpALA

Coinbase is partnering with Cloudflare to develop an x402 Foundation
Cryptopolite previously reported in September that Coinbase partnered with Cloudflare to create the x402 Foundation. The company stated that the initiative aims to simplify online payments with a new, open internet standard.
As a next step, we are developing the x402 Foundation with Cloudflare and other partners to ensure the standard remains open and can be used fairly by every company in the world.”
–Brian ArmstrongCEO of Coinbase.
Cloudflare argued that a lack of standardization has prevented widespread adoption of the x402 Payment Required. The company believes that a standardized payment protocol will facilitate payments without geographic, currency or formatting differences.
Mathew Prince, co-founder and CEO of Cloudflare, defended Coinbase’s work on the x402 protocol, recognizing that the core protocols of the Internet have always been driven by independent governance.
Eric Reppel, creator of x402 and head of Engineering for Coinbase Developer Platform, said the x402 Foundation will help make agentic commerce a unique opportunity to rethink how value moves online.
