What things cost
Most things on Hartii are free to look at. This page lists what the apps charge when you do something that moves money, so you can see the fees side by side. Each row links to the guide with the exact buttons.
Fees at a glance

Gas: the fee that is not Hartii's
Every transaction also pays gas, a fee for the Quai network itself. Hartii does not receive it. Gas changes with how busy the network is, so no page can promise a fixed number. Your wallet and the app show an estimate before you sign, and a failed transaction can still use gas. See Gas in the glossary.
A worked example
An airdrop to 100 wallets costs 1 + (0.05 x 100) = 6 QUAI in fees, plus gas. A list longer than 500 wallets splits into several transactions, and each one pays its own 1 QUAI. The Airdrop page reads the fee from the contract and shows it before you sign.
Which numbers can change
- Set by the owner: the Labs creation fee, which the contract does not cap.
- Set by the owner within a cap in the contract: the Labs curve trade fee (cap 3%), the Boost price per point (cap 10 QUAI), the Airdrop and Claim fees, the OTC Link fee (cap 2%) and the Gallery sale fee (cap 5%).
- Fixed in the contract: the QuaiAxe 0.5% vault fee, the 0.30% HartiiSwap fee and the Gallery royalty ceiling of 8%.
- Not listed here: prices that move by themselves, such as a token's price on its curve, a Wall of Blocks slot or a Shop skin. Read those on the page.
None of this is advice to spend money. Tokens can lose all their value, and nothing here promises a return.
