Mintable

The owner can create new tokens and dilute holders.

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 OP tokens

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