The art cannot be swapped
The contract's provenanceHash is a hash of all 888 image hashes, fixed at deployment with no function to change it. Regenerate from the repo and compare the number.
provenanceHash()[ DO NOT TRUST US ]
Every line here is something you can check.
Each row below is either a number on-chain or a file in this repository. Not one of them asks you to take our word for it.
0xbf220a73c71fed25b0f5331fe6c829ca06a0f9a1b2508ac7ec394c2bdcd9e2a6A hash of all 888 image hashes, written into the contract at deployment and unchangeable. Regenerate it from this repository and compare with the on-chain number — a match proves the art was never swapped.

Rarity cannot be edited
MicroDuckClubRarity packs all 888 tiers into eleven words at deployment, and the contract has no setter. distribution() counts each tier back for you.
distribution()The floor is backed by real ETH
The reserve is native ETH held by the contract, and floorPrice() = reserve ÷ circulating supply. It can only leave by burning an NFT — there is no admin path.
reserve() / floorPrice()The reserve share is fixed in the contract
reserveBps is immutable — no function can change it after deployment. It should read 9500, which is 95% of every mint.
reserveBps()The reveal draws once, and we cannot re-roll it
revealCommitment is immutable and published before minting opens. Exactly one secret satisfies it, and the seed also mixes in entropyAccumulator, which every mint folds into — so nobody can work out the result before minting starts. The only move available to us is to withhold the reveal, which does us no good. The owner and the treasury are both barred from minting, so the party who knows the secret cannot also influence the entropy. There is no VRF on this chain; this is the strongest construction it supports, but it is genuinely weaker than VRF, which the previous BNB Chain version used.
revealCommitment() / entropyAccumulator()The revenue split is a contract, not a promise
MicroDuckClubSplitter has no owner, no rescue and no sweep. Every wei that reaches it leaves to one of two addresses fixed at deployment — 60% to the NFT, which raises the floor for everyone, 40% to the reward buyer. Anyone can call distribute(); you do not have to wait for us.
totalToFloor() / totalToRewards()Supply is never extended
MAX_SUPPLY is the constant 888, and the contract has no mint path beyond it.
MAX_SUPPLY()Per-image hashes
All 888 of them live in provenance.json. Here are the eight legendaries plus the first:
