Finding

The provided evidence consists of headlines and dates from 2026, which do not contain the specific information required to verify the claim that Coinbase launched the x402 protocol in 2025. While the evidence confirms Coinbase's involvement with x402 and AI agent payments [1][4][6], it does not state the launch year or the specific date of the initial launch, making the 2025 claim unverifiable based solely on the supplied text.

Evidence examined

How this was checked

Evidence is fetched from published news and this site's own archive, never written by the model that judges it. Citations that do not point at a fetched source are removed, and a positive verdict with no surviving citation is recorded as unverified. A claim marked not established by available evidence means exactly that and nothing more.
