Winning NFT holders claim equal ETH prizes directly.

Sellout and the draw#
The final mint attempts one Chainlink VRF request and fixes a deadline 72 hours after sellout. A reverted request may be retried before that cutoff; an accepted request cannot be replaced. Randomness must be recorded strictly before the cutoff. Once recorded, anyone can finalize the draw and collect the separately funded executor reward. Recorded results never expire, even if the operator is absent. If no randomness is recorded on time, full mint-price refunds become available instead.
60% of actual mint revenue is split equally among the voted number of winning NFTs. The prize amount depends on the selected price, supply and winner count; 1 ETH is an illustration, not a minimum or maximum. Winners are distinct tickets, not necessarily distinct wallets. Permanent artwork identifies your ticket; it never announces a score or winning status.
R = p × N
Prize per winning NFT = (R × 60%) ÷ k
Chance per NFT = k ÷ N
- p
- The final mint price, in wei.
- N
- The sold-out collection’s NFT supply.
- k
- The voted number of distinct winning NFTs.
- R
- Total mint revenue, including separately funded sponsored mints.
Example: 1,000 NFTs at 0.01 ETH with six winners gives six prizes of 1 ETH and a 0.6% chance per NFT under the draw’s VRF/Keccak assumption. Allowed terms make prizes divide exactly. Different winning NFTs may share one owner.
Holder-only claims#
Open Rewards and select the collection. Its winning tickets list reads every current holder address, token ID, prize and claim status from the contract. Only the current holder can claim that ticket’s prize. Unclaimed winning tickets stay transfer-locked. Unpaid prizes remain reserved when later collections open. Holder rewards are separate: winning and non-winning NFTs from successful draws can claim from the season pool after season end, while the first-5% slots remain. Claiming one does not consume the other.
One lifetime sponsored ticket#
A settled prize can unlock one sponsored ticket in a later eligible collection. Each wallet can redeem at most one sponsored NFT for life, including prior registry history. Sponsorship pays the full mint price from a separate funded reserve; you pay gas. A refund does not restore the lifetime entitlement.
How the draw picks distinct tickets#
- Record verified randomness
The fixed coordinator records one valid VRF word before the cutoff.
- Derive a candidate
Keccak combines the word, chain, collection, round, supply, domain and persistent counter.
- Reject biased candidates
Candidates below the acceptance threshold are skipped. Every caller follows the same counter sequence.
- Select without replacement
Decode the accepted index into an ordered set of distinct NFT numbers. The selected IDs receive the highest scores.
Finalization performs bounded work and can continue from the saved counter. This samples the winners; it does not randomly shuffle all losing NFTs.
M = N × (N − 1) × … × (N − k + 1)
τ = 2²⁵⁶ mod M
Accept c ≥ τ; then index = c mod M
Winner score at rank r = N + 1 − r
- N, k
- The sold-out supply and the voted winner count.
- M
- Number of possible ordered selections of k distinct tickets.
- c, τ
- The 256-bit candidate and rejection threshold. Rejecting the short remainder removes modulo bias.
- r
- Winner position, starting at 1. Scores are distinct; all winners receive the same ETH prize.
Unbiased sampling relies on the VRF/Keccak assumption. Keccak expansion is deterministic, not new independent entropy. Losing tickets receive the remaining unique scores in token-ID order.
Check the selected collection’s terms and network before you sign.
