📈 The Curve
Every box sold makes the next one +0.046072% more expensive. No exceptions, no whitelist, no insider price.
Price of box n p(n) = 0.01 x 100^((n-1)/9998) ETH
Step per box r = 100^(1/9998) = 1.00046072
Cost of first N C(N) = 0.01 x (r^N - 1) / (r - 1)
Cost of q boxes from box n = C(n+q-1) - C(n-1)

Full launch math
See Launch — 1B supply, 0% team allocation, 350M bought on market and locked in a halving vault.
🛒 Mint
- Open Mint Box, pick 1–20 boxes
- Optional: enter an inviter address (first mint only) → referral multipliers
- Confirm — you pay
C(n+q-1) − C(n-1), exactly what the curve says
Example — 10 boxes starting at box #3,000: C(3,009) − C(2,999) = 0.399 ETH (avg 0.0399/box).
🎁 Reveal
Mint box (ERC721) -> Reveal -> box burned -> Hero NFT minted
Attributes are generated onchain from box ID, token ID, block hash, timestamp and block.prevrandao.
- 15 archetypes, uniform 1/15
- Rarity drives starting Attack and upgrade multipliers → Rarity Basics
- Procedural color palette, unique per hero
🎲 Fairness
- Randomness comes from the chain, not a server. No pre-seeded list, no reserved IDs.
- Every rarity roll is a public transaction you can replay.
- Team boxes: none. If the team wants a hero, the team pays the curve.
⚠️ Rules
- One reveal per box. Box is burned, hero is permanent.
- No refunds. The curve never goes down.
- 9,999 heroes maximum, forever.
