Notes from the exchange.
Working notes from the people building oxavane — on supply-chain transparency, where attention actually went, and the standards we hold inventory to. Technical, specific, and free of the usual ad-tech noise.
Why we publish app-ads.txt and sellers.json on day one
Before we routed a single bid, we published the files that prove who we are and what we
are authorized to sell. Here is what ads.txt, app-ads.txt and
sellers.json actually declare, how buyers use them to verify the supply chain,
and why an exchange that hides this is one you should not trust.
Connected and in-venue: where attention actually went
Audiences spend hours every day alongside screens that are not their phones — the connected TV at home, the display in a moving rideshare, the panel at checkout, the monitor in the gym. That supply is real, premium, and historically almost impossible to buy programmatically. The case for unifying it into one exchange, argued with moments rather than hype.
How we evaluate inventory quality
Curation is not a marketing word — it is the work of deciding which screens belong on the exchange and which do not. Real screens with real audiences, accurate declarations, correct taxonomy, and zero tolerance for incentivized, made-for-advertising or auto-refresh abuse. The bar we hold publishers to, and why it protects honest ones most of all.
