ZKsync responded to the question "Why do some addresses with zero transactions still receive allocations", stating: Airdrops are divided into user-based allocations (accounting for 89% of airdrops) and contributor-based allocations (accounting for 11% of airdrops). Wallets in the contributor category do not need to show activity on ZKsync Era. For example, contributor allocation focuses on those who build early projects on ZKsync, contribute to related Github repositories, conduct security research, manage communities on Discord or participate in Degen, Bonsai, Crypto the Game, Pudgy and Milady communities. There are 184 addresses that meet the eligibility criteria for ZKsync Lite and have bridged assets on ZKsync Era but no other transactions; these wallets qualify for airdrop. In addition, ten test addresses were added for internal quality assurance and testing. These addresses were allocated a minimum of 917 tokens each. Once claimed, these tokens will be sent to burn address.
