Markets and Launch
Prediction markets settled against a live oracle, and token launches that record no buyer address.
Both contracts are deployed on Starknet mainnet — the addresses and deploy transactions are in the evidence, and surface status computes their state from that same file rather than asserting it.
Markets
Prediction markets that settle against Pragma, the on-chain oracle. The price strip and chart on the surface are live reads from the same oracle a market settles against — not a decorative chart, and not a fixture.
Betting is done from shielded notes, so the bet is not linked to a public address of yours. The size of the bet is public, like every leg that touches an open note.
There is one privacy caveat the app states on the surface itself: your bet is hidden as long as your denomination has company. If you are the only participant at that size, your bet is identifiable. A privacy claim that is usually true is the most dangerous kind, so the product carries the condition rather than the headline.
Launch
Token launches with an epoch mechanism. Buys arrive as withdrawals from the pool, which means:
the launch records no buyer address.
That is the narrow, true claim. The tempting version — "your address never appears on the launch" — is false and is on the refused claims list, because your address does appear on the deposit that funded you and on any public withdrawal you make later.
The difference between those two sentences is exactly the difference this product is about.
