Reason: zkSync's use of ZK as the token name caused a conflict
On May 21, 2024, according to sources, zkSync plans to hold a token generation event that week, and token issuance (including airdrops) will take place within 30 days after TGE, with a total supply of 21 billion tokens. The zkSync token airdrop is expected to take place around June 13th.

And zkSync wants its token to use ZK as its token name. But the problem is that another zk project, Polyhedra, has already used this name and is trading under this token name on some mainstream exchanges

Subsequently, Bybit announced on May 23 that it would adjust the name of the Polyhedra token and use the ZK code to register zkSync on its spot trading platform.

On May 24th, Polyhedra publicly condemned the zkSync token name selection, stating, "It is incredible that in 2024, even though ETH ETFs have been approved, there are still some projects that bring benefits to all parties and deprive others of the token names they deserve."
