Transfer Hook

A Token-2022 extension that runs a custom program on every token transfer. Can implement arbitrary restrictions including blocking sells while allowing buys. A transfer hook on a memecoin is a kill signal in 2026 — no legitimate memecoin use case justifies it.

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 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 Non-zero transfer fees on a memecoin are a red flag: the fee rate can be changed at any time if the authority has not been revoked, enabling honeypot escalation. →
