## Deposit gas tokens

You can also deposit native gas tokens on each supported chain, which can be used to cover gas fees on those chains.

In the **Gas Token** tab, you can view the balance and transaction records of gas tokens on each chain and initiate deposits. For supported gas tokens, refer to [Supported Token Types](/en/portal/fee-station/introduction#supported-token-types).

1. Log into [Cobo Portal](https://portal.cobo.com/login).
2. You can access it by clicking **Fee Station** in the left sidebar.
3. Switch to the **Gas Token** tab and find the gas token for the target chain (for example, TRX, ETH, or MATIC).
4. Click the <img src="https://mintcdn.com/cobo-6/D190GK1_IvLajUyZ/en/images/fee-station/icon_deposit.svg?fit=max&auto=format&n=D190GK1_IvLajUyZ&q=85&s=dfbd949ab4807c7a8f7b7a573448815a" className="icon" width="32" height="32" data-path="en/images/fee-station/icon_deposit.svg" /> deposit icon next to the gas token, and follow the instructions to complete the deposit.

## Configure payment preferences

In the **Gas Token > Payment Preferences** tab, you can configure on-chain transaction fee payment strategies for MPC Wallets and Web3 Wallets based on supported chains.

Each payment preference controls when Fee Station covers gas fees for an address: you can choose to cover fees only when the wallet balance is insufficient, or to always cover them. If you do not configure a preference for a chain, the system default applies.

<Note>Whitelist-based fee configurations may apply to specific addresses. As a result, the fee behavior for those addresses can differ from the preference you set here, and changing an address's whitelist membership can change which fee behavior applies.</Note>

## TRON fee payment

For TRON USDT transfers, Fee Station pays the on-chain fee in one of two ways:

* **Energy mode**: Fee Station uses available or rented energy on the sending address to cover the transfer, which avoids burning TRX and is the lower-cost option. Fee Station prioritizes this mode whenever energy can be applied.
* **TRX burn mode**: When energy cannot be applied to the transfer, Fee Station pays the fee by burning TRX, which costs more than energy mode.

The fee shown for a TRON transfer reflects the method actually used, so the displayed amount can differ between transfers depending on whether energy was applied.

<Note>If you have pre-rented energy on a TRON sending address but still see a TRON insufficient-energy or insufficient-fee error, confirm that Fee Station is enabled and funded for TRON and that a TRON payment preference is configured under **Gas Token** > **Payment Preferences**. If the error persists after the Fee Station balance is funded, the address may require additional account configuration before pre-rented energy can be applied.</Note>
