This cluster of 16 wallets, including seed 0x99a3…631a and first-funder 0xad8c…21cf, is likely operated by the same person, linked by a clear funding lineage. Collectively, this wallet family appears to be a kiosk-flipping crew, primarily engaging in NFT sales across a small number of collections, with a notable focus on "Github Nft" and "Seal Adventure." No wallets in this family have been flagged by bot detection, and while the funding lineage strongly suggests a single operator, this does not confirm identity.
