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 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 Honeypot A token configured so that buy transactions succeed but sell transactions fail or return near-zero output. Implemented on Solana via Token-2022 TransferFeeConfig at extreme values, freeze authority abuse, or malicious transfer hooks. Quick test: buy a minimal amount, wait one block, simulate the sell on Jupiter. → Security Hard Rug A rug pull executed by the developer directly withdrawing liquidity from the AMM pool. The liquidity disappears in a single block, the token price goes to zero, and there is nothing to trade against. Mechanically closed for Pump.fun-graduated tokens via automatic LP burn; still active on manually-deployed pools. →
