Logic can be swapped by the admin.

Stablecoins and large tokens often keep admin powers (mint, pause, blacklist) on purpose — for regulation or recovery. Flags describe what the code allows, not intent. Re-run the scan.

How to avoid fake ZK tokens

Match the full address, not just the first and last characters — scammers mint look-alike addresses and copy the name zkSync and ticker ZK exactly.
Check the network: the Ethereum address above is only valid on Ethereum; each network has its own ZK contract.
On the explorer, a genuine ZK contract shows large holder counts and long history; a fresh clone has neither.
