How a transfer fee works
A Token-2022 mint can set a fee that is withheld from each transfer in the recipient's token account. The withdraw-withheld authority collects it later. See what the fees are.
What holders see
They receive slightly less than the amount sent, and apps may show the fee. Buyers check it before buying, so state it clearly. A fee that rises later is a recognized trap, see Token-2022 scam traps.
Collecting
Jumpbit Fee Collector scans every token account of a Token-2022 mint, including pool vaults, harvests withheld fees and withdraws them to your account. It states a minimum of 0.05 SOL rising linearly to 1 SOL per 100,000 accounts, plus network fees, and you must be the withdraw-withheld authority. See how to collect the fees. Open Fee Collector.
