0x Project, the decentralized exchange infrastructure provider that has quietly powered swap functionality for some of crypto’s biggest names since 2017, just made its Cross-Chain API generally available. The tool lets developers handle token swaps, payments, and asset transfers across more than 25 blockchains through a single integration point.
Instead of stitching together a half-dozen different bridges and routing protocols, developers plug into one API and let 0x handle the mess underneath.
What the beta numbers tell us
The Cross-Chain API isn’t arriving untested. Its private beta kicked off on February 25, 2026, and in the roughly three months before general availability on June 4, the system processed over $230 million in bridged volume.
The performance stats from that beta period are worth noting. The API maintained 99.97% uptime, which translates to roughly 13 minutes of downtime per month. Median bridge time clocked in at just 10 seconds, and median quote response times came in under 750 milliseconds.
