TransferFeeConfig

A Token-2022 extension that withholds a configurable percentage of every transfer, collectible only by the designated fee authority. Non-zero transfer fees on a memecoin are a red flag: the fee rate can be changed at any time if the authority has not been revoked, enabling honeypot escalation.

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. → 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. → 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. →
