Built in the open. Pre-launch.
Commerce was built for browsers.
We're building it for agents.

The buyer is changing.
For most of the web, a purchase has been a person, a browser, and a checkout button. That era is ending.
Software is learning to buy on its own. Within a decade, more transactions will be initiated by agents than by humans, and every merchant will need to be reachable by software it has never met.
Steelyard is the open framework underneath. One definition. Any protocol. No middleman.
Define commerce once.
Reach every buyer.
The next commerce stack will be many protocols, many rails, many runtimes. Steelyard is the open layer above all of them.
