NEO HALLOWEEN

• Take back your NFT

  The creator holds a wipe key and can remove an NFT from any wallet, including one that paid for it on the open market.

• Freeze your NFT

  The creator holds a freeze key and can stop a chosen wallet from transferring or selling what it holds.

• Halt every transfer

  The creator holds a pause key and can stop the whole collection from moving, for everyone, at once.

• Mint up to 250

  The creator holds a supply key and can keep minting until 250 exist. A collection is only as scarce as its cap.

• Rewrite these rules

  The creator holds an admin key and can add or remove every permission above later. Whatever this cannot do today, it cannot do yet.

Read from the Hedera mirror node, where a token declares its keys as properties rather than hiding them in contract code. These are the powers the issuer holds, not a judgement about the token: plenty of legitimate projects keep a supply key, and a stablecoin needs a freeze key to comply with the law. What matters is knowing which ones exist before you buy.
