Why transfer fees on Token-2022 matter
A 1% fee is a nuisance. A fee someone can change is a trap door.
Token-2022 is Solana's newer token standard. It adds "extensions" the old standard never had, and one of them is a transfer fee: a cut taken every time the token moves, including your buys and sells.
The fee you see
A small fixed fee, say 1%, mostly just costs you on every trade. Annoying, often legit, worth knowing before you pay it twice on a round trip.
The fee you don't see coming
The real risk is the fee authority. If a wallet still controls it, the fee can be raised later, sometimes to the point where selling is pointless. That's a honeypot built from a feature.
On Super Inu ($SI) we caught a live 1% fee where the authority wallet can still change it, while a major data source reported 0%. That's why we read the mint ourselves.
Other extensions to know
- Transfer hooks: custom code that runs on every transfer and can block sells.
- Permanent delegate: a wallet that can move or burn your tokens.
- Default frozen state: new holders can start frozen.
What to do
- Check fee size and whether the authority is revoked.
- Factor the fee into both sides of your trade.
- Any changeable fee = WARN until proven otherwise.
Not financial advice. Every booby trap has a tell.
