On July 15, zkSync officially announced an NFT airdrop for NFT players in the ecosystem. The first batch of 10,000 addresses has received the airdropped NFT. As the much-anticipated head layer 2, zkSync’s move has attracted heated discussion in the community. Everyone is speculating, is obtaining this NFT equivalent to qualifying for the zkSync airdrop token?

To answer this question, Trusta Labs analyzed the on-chain interaction behavior of 10,000 users who have obtained NFTs on zksync Era:

Interactive behavior analysis

The average number of transactions for zkSync Era users across the entire network is 21. This NFT airdrop user: 70% of the cumulative number of transactions >= 20, which is higher than the average. 15% of the airdrop accounts have a total of <= 10 transactions, including 690 users or even <= 4 transactions.

Transaction volume

The cumulative transaction volume of more than half of the zkSync Era users on the entire network is 44 U. This NFT airdrop user: 15.4% of the address transaction volume <= 50 U, of which there are even 530 addresses with a <= 10 U (much lower than the average).

The average number of active weeks for zkSync Era addresses across the entire network is 3.6 weeks. Users of this airdrop: 25% have been active for no more than 3 weeks, of which 700 are only active within one week.

special circumstances

  • "0" transaction "winning" address

We found the following three addresses, which have no interaction records in the zkSync Era and still received airdrops. According to the requirements for interactive top 100 NFTs, these three addresses obviously do not meet the requirements. It is speculated that it may be an official test address. It is recommended that @zksync provide an official explanation to avoid misunderstandings.

Address one: 0x200ae0ab4e65bf0a80748cf4ebce814667513ba5 (https://explorer.zksync.io/address/0x200ae0ab4e65bf0a80748cf4ebce814667513ba5)

Address two: 0xa0fdb2f6cf2bf189db73b294a60088fef751bfcd (https://explorer.zksync.io/address/0xa0fdb2f6cf2bf189db73b294a60088fef751bfcd)

Address three: 0xe8bd3908c645dab3ced6b0ca75304ca3a31276c0 (https://explorer.zksync.io/address/0xe8bd3908c645dab3ced6b0ca75304ca3a31276c0)

  • Inactive addresses with only 1 – 2 transactions

There are 118 addresses in this airdrop that have only had 1 transaction in history, and all of them were lucky NFT transactions. The cumulative number of transactions in the history of 135 addresses is only 2.

Typical address: There was only 1 transaction 3 months ago, but I was still lucky enough to get the NFT airdrop because the address was the beautiful number 0x 0.

  • There is also fund aggregation behavior in the airdrop address.

Among the 10,000 addresses that received NFT airdrops, there is also fund aggregation behavior between different addresses, and there may be multiple accounts controlled by the same entity:

Cluster one: 0x01bffc8dc41e26d98c3cef8b045726726134d1d3 has transferred funds to 7 addresses, and these 8 addresses have all received this NFT airdrop.

0x01bffc8dc41e26d98c3cef8b045726726134d1d3, 0x0221bde0421fb6728565362c7a07139b8b8a547f, 0x012d3e07a0985fead3929636087b2f3879f77b 9e,0x0b4b156a1fd4b3c0ea779fcb0359cedf36345ab6, 0x09f43533e974c590ef827a038635066a21bfadd9, 0x09b713ea5899cf2f224d5fefc7701bf00b73cf9f, 0x0b65d471f86830d33afa0b66028605a483bfdced, 0x0b40e7f11a7a6a4c0dc3ee739f0b06d9f05f9587

Cluster two: Five addresses have all received this NFT airdrop, and there are fund transactions between them.

0x00e73720d841de3884a6074e6aaf506fd8f15851, 0x076e9da02e0767c2bd40adec8779a30f14aa7a8c, 0x0a6dc610a7cd0142d662c14c416bfae4bb231a10, 0x0c25fef7a6c39696727650c4d9ab9367e25dd296, 0x0d68dc12a1ce249c12d5edeaf1d953508c232da6

Analysis of Witch Behavior

For the 10,000 addresses that received the airdrop this time, witch behavior was detected through two different methods:

TrustScan Sybil Detection

Using TrustaScan to scan the behavior of this airdrop address on the main network and Arbitrum, 1,408 witch addresses were hit (witch rate >14%).

summary

  1. We found that this round of zkSync airdrop address screening rules are single and do not take into account interactive value and activity. Many official airdrop addresses have average contributions to the zkSync Era (contributions of transaction amount, gas fee and active time are lower than average, or have Obvious witch behavior), airdrops only encourage users to participate in ecological NFT projects, so receiving NFT airdrops is not completely equivalent to receiving Token airdrops in the future. On the other hand, it is speculated that zkSync’s rules for user rewards and airdrops, in addition to common indicators such as transaction number and amount, may also refer to the diversity of ecological contributions in the future.

  2. Trusta will soon launch zkSync on the KYA (Know Your Account) user chain interaction and value scoring product, which will comprehensively evaluate user value from multiple dimensions such as frequency, amount, loyalty, diversity, and identity rights, and rank all participating users. , and guide users to safely interact with popular and high-potential projects on zkSync Era. At the same time, the unique TrustScan witch risk analysis function is embedded and integrated to help users make risk warnings. All users are welcome to try it out.
