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.

Security Freeze Authority Rug A rug executed by using an unrenounced freeze authority to selectively freeze large holder accounts before dumping. The developer blocks targeted holders from selling, then sells their own bag into the remaining buy pressure. Prevention is simple: verify freeze authority is null before entry. → 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 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. →
