# Token System & Fees

## Overview

T-Tokens are Solana **Token-2022** tokens with the transfer fee extension enabled. A fee can be charged on each transfer of a T-Token, including the transfers that happen inside DEX buys and sells. The standard rate is 0.2%. T-SpaceX has had a 0% transfer fee since Solana epoch 1047 (October 1, 2026).

Collected fees go to Tessera's Treasury and, where the sender is registered in the [referral program](/features/referral-systems.md), to the sender's referrers (up to three levels, up to 35% of the fee in total).

How the transfer fee works:

* The fee is withheld from the amount transferred: the sender is debited the amount, and the recipient receives the amount minus the fee. No extra balance is needed to cover the fee.
* Fee = amount × rate, rounded up to the token's smallest unit.
* Each token mint has one rate that applies to all holders. The rate can be changed by the mint's fee-config authority; changes are recorded on-chain.
* The fee logic is part of Solana's Token-2022 program.
