How Vault Units work

Each bottle is minted as one ERC-1155 token series with a fixed total supply of units, set at listing time — there's no separate "mint the NFT" step followed by "split it later." Minting and fractionalizing happen in the same on-chain call.

• One bottle = one token ID.

  All units of that bottle share the same ID, the same image, and the same metadata (photos, provenance, tasting notes) — they are fungible copies of a fractional claim, not individually unique items. There are no per-unit serial numbers.

• Two markets, same bottle.

  Primary sale is units bought directly from Vellichor (never previously owned). Secondary market is units resold between holders. Both can be active simultaneously for the same bottle.

• Sellers cannot buy their own listings.

  This is enforced on-chain, not just in the interface — it prevents wash trading (a seller creating fake demand by trading with themselves).
