What are DEX provider fees, networks, and the transaction limit?
DEX transactions have two fee items: the provider fee and the network (gas) fee. Both are taken into account before the transaction and appear as separate rows in the transaction details afterwards. DEX transactions can be made on different blockchain networks, and buying and selling always takes place against USDT.
Which fees apply to DEX transactions?
Two items apply to DEX transactions. Both are included in the Minimum Received calculation on the summary screen; in other words, the lower limit you see on the screen is the amount you will receive after fees are deducted.
| Item | What it is paid for |
|---|---|
| Provider fee | The commission charged for executing the DEX transaction |
| Network (gas) fee | The amount paid to the network for processing the transaction on the blockchain |
When you tap the info icon next to the Minimum Received row, the screen that opens also states the provider fee rate. After the transaction is complete, you can see the Commission and Network fee rows separately in the transaction details.
Note: Fee rates are not fixed and may be updated from time to time. For this reason no rate is given in this article — check the summary screen before the transaction and the transaction details afterwards
On which networks can I transact?
The networks available for DEX transactions vary by token; a token is traded only on the network it is on. Today, tokens on the Ethereum, Base, Arbitrum, Optimism, Polygon, Avalanche, BNB Smart Chain, Solana, and HyperEVM networks are supported.
You can see which network the token you are trading is on in the Network row of the summary screen. The Estimated Completion Time row below it shows the estimated duration for that network; on networks such as Ethereum this duration is slightly longer than on others.
Note: The list of supported networks is updated from time to time. The network on which the transaction will take place is always stated on the summary screen
Which asset is used in DEX transactions?
DEX tokens are always paired with USDT:
- When buying, the USDT in your Paribu balance is spent
- When selling, the proceeds return to your Paribu balance as USDT
What is the transaction limit?
There is a minimum and a maximum amount per transaction on the DEX. These limits are not fixed; they are determined by the token and market conditions. When you enter an amount outside the limits, a warning appears on the screen stating the minimum or maximum amount you can transact.
This is not a total limit — you can make more than one transaction if you prefer.

Frequently asked questions
Do I pay the network (gas) fee separately?
The network fee is an item separate from the provider fee and appears as its own row in the transaction details. However, this fee is also deducted when the minimum received amount on the summary screen is calculated; the lower limit you see on the screen already includes the network fee.
Where can I see the fee rate?
When you tap the info icon on the Minimum Received row of the summary screen, the screen that opens states the provider fee rate. After the transaction is complete, the Commission row in the transaction details shows the actual commission applied to that transaction.
On which networks can I transact?
On the network the token is on. Today, tokens on the Ethereum, Base, Arbitrum, Optimism, Polygon, Avalanche, BNB Smart Chain, Solana, and HyperEVM networks are supported; the network of the transaction is stated in the Network row of the summary screen.
Can I buy a token on one network and sell it on another?
No. A token is traded only on the network it is on; you sell the token you bought on the same network.
What is the maximum amount I can transact at once?
The upper limit per transaction varies by token and market conditions. When you enter an amount above the limit, the screen states the maximum amount you can enter. You can continue by making more than one transaction.
