Update Authority

The Metaplex or Token-2022 authority that can change a token's name, ticker, logo, and linked social accounts. Retaining this enables a metadata rug — renaming the token mid-pump and redirecting links. Acceptable for doxxed teams with track records; suspicious for anonymous launches.

Tokenomics Mint Authority The SPL Token Program authority that can create new tokens. If set to null, supply is permanently fixed and the inflation rug vector is mechanically closed. Pump.fun and LetsBonk set mint authority to null by default at launch. → Tokenomics Freeze Authority The SPL Token Program authority that can freeze any holder's Associated Token Account, blocking them from selling. Must be null for any memecoin worth touching. Active freeze authority is a disqualifying red flag with no legitimate justification on a memecoin launch. → Tokenomics Token-2022 Solana's extended token standard supporting transfer fees (TransferFeeConfig), transfer hooks, PermanentDelegate, confidential transfers, and other extensions. Not malicious by default, but enables honeypot configurations unavailable in classic SPL. A Token-2022 token on a memecoin is a forced pause requiring investigation of every active extension. →
