Luxury units
Emerald issues a small number of luxury units. Each one references the aftermarket price of a single, specific item, chosen because it trades often enough to have a real price rather than a sticker price.
Units are EmeraldMakerWindow tokens: the market maker lives inside the token. Each carries its own on-chain oracle price and quotes both sides of its own Uniswap v4 pool.
What a unit is not
It is not a claim on a physical object. It is not redeemable. It is not issued by, or connected to, the manufacturer of the referenced item. Being blunt here builds more trust than hedging does.
