  "notes": "Discovery: OpenSea Events API (api.opensea.io/api/v2/events/collection/r-mnants) returned 401 Missing API Key in this environment, so discovery/verification used ERC721 Transfer logs + tx receipts directly against public RPCs (rpc.mevblocker.io/publicnode for the pinned window; mainnet.gateway.tenderly.co, which serves older archive ranges, for the 7-day seed lookback), decoding Seaport OrderFulfilled logs by hand. Confirmed chainId=1 and toBlockHash exactly on publicnode. Window: exactly one qualifying transfer of the collection inside [26027905,26035049]: block 26028154 (2026-09-21T20:06:11Z), tx 0xd0a33577f1f97787afba2e89d775917bd182b6f26b8a92f57761109d347be990, Seaport 1.6 (0x0000000000000068f116a894984e2db1123eb395) OrderFulfilled, offerer 0x827af7ec6a9ec0d3262a77a2e80da82f1067be3d, buyer 0xf05155f792819710da259c103d30e4b70178ea9f, tokenId 62, offer item ERC721 qty1, consideration = 3.465 ETH to seller + 0.035 ETH fee = 3.5 ETH total (3500000000000000000 wei). This matches CoinGecko's one_day_sales=1, one_day_average_sale_price=3.5 for r-mnants. Seed: walked ERC721 Transfer logs on the contract from fromBlock-1 back 50400 blocks (~7 days) via tenderly's archive endpoint; found 8 transfers, most of them plain (non-Seaport) transfers or a non-Seaport 0.0148 ETH compact-log settlement (excluded, far below floor, no Seaport evidence). The nearest qualifying Seaport sale is tx 0x9cc7f3627887d129bdc89ef30a37d80e5ddb72d64a31c07c01784dbb40ed3602, block 26006798 (2026-09-18T20:31:59Z), a matched pair of Seaport orders, tokenId 94, ERC20(WETH) consideration of exactly 3.0 ETH (3000000000000000000 wei) from buyer 0x23ccccd44bab6144b4923e9345c824a8bb45d106 to seller 0x9281dc14a0fcb2377e6e98dac5f79ae8c763e55d, matching the NFT Transfer direction; no separate fee leg identified in the decoded consideration beyond this. TWAP: P=3.0 ETH for [19:15:45, 20:06:11) = 3026s, then P=3.5 ETH for [20:06:11, next-day 19:15:45) = 83374s (sums to 86400s). Integral = 3026*3e18 + 83374*3.5e18 = 300887000000000000000000 wei*s; TWAP = floor(integral/86400) = 3482488425925925925 wei (~3.4825 ETH). Floor context (not part of the TWAP): CoinGecko NFT endpoint (api.coingecko.com/api/v3/nfts/r-mnants), retrieved 2026-09-22, floor_price.native_currency = 4.1 ETH ($11277.99); OpenSea's own stats endpoint could not be reached (401, no credential). Limitations: OpenSea discovery/index step could not be performed for lack of an API key; coverage instead relies on complete on-chain ERC721 Transfer log enumeration plus receipt-level Seaport decoding, which is a stricter, not looser, filter. Wash-trading flag: the excluded 0.0148 ETH event and several bare transfers for tokenId 136/94 shortly before the seed show repeated back-and-forth movement among a small set of addresses; these were excluded as non-qualifying (no Seaport/marketplace settlement decoded), which may itself indicate wash/lending activity around this collection, but this is an observation, not a proven finding of common beneficial ownership."
