This wallet family, comprising 0x21a0…ab0e and its first-funder 0x40d6…2a70, is likely operated by the same person, linked by a clear funding lineage. The family collectively acts as a quiet staking operator, with the seed wallet primarily engaging in `sui_system::request_add_stake` and `sui_system::request_withdraw_stake` functions. No wallets in this family were flagged by bot detection, and there is no NFT trading activity observed. While the funding lineage strongly suggests a single operator, this is evidence-backed attribution and not identity-confirmed.
