How it works

1. Mint. Gen 0 costs 0.0025 ETH (max 5 per wallet, IDs 1–5,000). Gen 1 (IDs 5,001–25,000) costs 20,000 / 40,000 / 60,000 BLOOD by tier, and that BLOOD is burned.
2. Reveal. Your role is not decided in the mint transaction. The request is sealed against the hash of the next block; the keeper (or anyone) opens it a moment later. You cannot preview or re-roll a result, and neither can we.
3. Stake. Send inhabitants to the Bank, no approval transaction needed. Villagers produce; Vampires collect.
4. Claim or exit. Decide between steady 80% claims and the 24-hour all-or-nothing exit.

Traits are drawn with weighted rarities (a Bone Crown is far rarer than a Chestnut Crop), and the contract keeps a registry of every trait combination ever revealed. If a new inhabitant would look exactly like an existing one, only its look is re-rolled, its role, Alpha and theft outcome never change. The combination space is roughly 900,000 looks per role, so re-rolls are rare and duplicates are effectively impossible.

BLOOD is not pre-minted into a rewards pool. When a Villager claims, the Bank calls BloodToken.mintStaking and creates the tokens at that moment, the Bank is the only address allowed to mint, and its lifetime emission is hard-capped at 2,400,000,000 BLOOD.

The cap is paid out in four tranches of 600M. In the first tranche every staked Villager earns 10,000 BLOOD a day; at each tranche boundary the daily rate halves (5,000 → 2,500 → 1,250). Because every Villager earns the same rate, more stakers spend a tranche faster, the schedule is a budget, not a calendar. When the fourth tranche is exhausted, production stops for good and BLOOD becomes a fixed-supply token.

The only BLOOD that exists before the first claim is the 5,000,000 genesis liquidity that is paired with 1.588 ETH from Gen 0 sales into a permanently locked Uniswap v4 position when Gen 1 launches. Gen 1 mints burn BLOOD, so total supply can never exceed the 5,000,000,000 hard cap and in practice trends far below it.

Vampire rewards are the same freshly minted BLOOD: the 20% tithe is accounted to the Vampire pool at claim time and minted when a Vampire claims. If no Vampire is staked, the tithe accrues and is paid to the first Vampire that enters.

Any inhabitant can be raised from level 0 to level 4 by spending BLOOD. Villagers gain +25% production per level (level 4 doubles it): 20k / 40k / 80k / 160k BLOOD. Vampires gain +1 effective Alpha per level, a bigger tithe share and better theft odds, and pay double: 40k / 80k / 160k / 320k.

80% of every payment is burned, 20% goes to the creator. Levels are part of the NFT: they show in its metadata (blood drops in the corner), survive transfers, and a staked inhabitant is re-weighted the moment it levels up, BLOOD earned so far is frozen and paid with the next claim. The level ladder is fixed in the contract; nobody can change the prices.

• Gen 0 sellout starts a one-hour timer; afterwards anyone can call launchGen1.
• It seeds a 1% BLOOD/ETH Uniswap v4 pool with 5,000,000 BLOOD + 1.588 ETH. The position NFT is locked forever; only trading fees can ever be collected, and they go to the creator.
• A tiny guard hook prevents anyone from initialising or seeding the pool before the launch transaction. It has no admin and is inert afterwards.

These are the exact addresses this app reads and writes. They are immutable; if they ever change, this table changes with them because both come from the same configuration.
