How the cellar works

The game in 1 minute

On Chain Wines is a patience game on Ethereum. You mint a wine bottle (an NFT). For 60 days it ages in the barrel and drips $WINE — an ERC-20 token — every day, dripping faster as it gets older. You claim that $WINE whenever you like. At day 60 the wine is bottled: production ends and the bottle becomes a finished collectible. Two bottled wines of the same cuvée can be blended (for ETH) into one fresh bottle of the next tier, which starts its own 60-day run. The ladder is Table → Reserve → Grand Cru, and it ends there.

Minting

Three cuvées, priced in ETH, each with a fixed sale supply. Rarer cuvées drip harder for the same 60 days. Once a cuvée sells out, the only way to get one is the open market — or, for Reserve and Grand Cru, the blending bench.

Aging

A bottle's age runs from its mint block and never resets — not when you claim, not when it changes hands. The drip multiplier steps up with age and production stops entirely at day 60:

Claiming

Claims are counted in full days: each completed 24 hours since your last claim adds one day of drip at whatever multiplier the bottle had that day. Partial days are never lost — they roll into the next claim. One transaction can claim your entire cellar at once, which is how you keep mainnet gas sensible.

Trading

Bottles are standard ERC-721 NFTs — sell them on OpenSea, send them to a friend, whatever you like, mid-aging or bottled. On every transfer:

• Accrued, unclaimed $WINE pays out to the seller automatically.
• The buyer starts with a clean claim counter from the moment of transfer.
• Age travels with the bottle. A day-40 bottle is a day-40 bottle in anyone's wallet — its remaining production is public and priced in.

Blending

The bench takes two bottles of the same cuvée plus an ETH fee, consumes both, and mints one bottle of the next tier — fresh, day zero, full 60-day run ahead of it. Rules of the bench:

• Both bottles must be the same cuvée, and both must be yours.
• Any unclaimed $WINE on the pair pays out to you before they are consumed.
• Blending an unfinished bottle forfeits its remaining production — the site warns you first. Bottled wine blends with nothing left behind.
• Grand Cru is the end of the ladder: it cannot be blended further.
• Every blend shrinks total bottle supply by one. The cellar only gets scarcer.

Cosmetics

The only place $WINE is spent. Cosmetics are permanent upgrades that live on the bottle itself and show up in its art everywhere — the cellar, OpenSea, anywhere the metadata is rendered. They travel with the bottle when it sells, so $WINE spent on style becomes part of the bottle's market value. Every cosmetic purchase burns the $WINE forever. The launch catalog: custom label art, a name etched in the glass, a wax seal, vintage cellar dust.

$WINE

An ERC-20 with no pre-mine, no team allocation, and no faucet: bottles dripping in wallets are the only source. Because every bottle's lifetime output is fixed at mint, the genesis supply ceiling is arithmetic:

Blended bottles run their own barrels, so emission can pass the genesis cap — but every blend consumes two bottles and costs ETH, so total emission stays bounded and shrinking-supply, while cosmetics burn $WINE out of circulation on the other end.

Contracts

Planned architecture: an ERC-721 for bottles and an ERC-20 for $WINE that only the bottle contract may mint. Aging is computed from block timestamps — nothing runs on a server, and the site is just a window onto chain state.
