What is Fee Station

On different blockchains, transactions require different native tokens (gas tokens like ETH, TRX, or SOL) to pay for gas fees. This means you need to prepare and manage gas balances for each chain. If any address runs out of gas, transactions may fail. Meanwhile, you might need to settle various types of fees across Cobo Portal, such as service fees and custody fees. These are often handled via emails, spreadsheets, and manual reconciliation—making the process inefficient and error-prone. Fee Station helps you simplify this. It’s a one-stop fee management platform on Cobo Portal. Once any member deposits to the Fee Station account, it can automatically cover on-chain gas fees for all MPC Wallets or Web3 Wallets transactions in your organization based on the strategy you configure, and also settle various types of fees with a single balance.
Currently, Fee Station supports paying gas fees for transactions made with MPC Wallets and Web3 Wallets on EVM-compatible chains, TRON, and Solana.

​
Supported wallet types

Fee Station gas fee payment is available for MPC Wallets and Web3 Wallets only. In the Cobo wallet taxonomy, Web3 Wallets are a subtype of Custodial Wallets. Custodial Wallets also include Asset Wallets, which are not eligible for gas fee payment. Asset Wallets can use the Fee Station balance to settle custody fees only.

​
Who should use Fee Station

Fee Station is ideal for any team looking to simplify on-chain fee management, especially:
  • Exchanges and wallet service providers: Centrally manage and prepay gas fees for end-user transactions, reducing operational overhead.
  • Payment service providers: Use flat-rate or unified billing models to abstract away blockchain complexity and deliver smoother user experiences.
  • Enterprise developers using Cobo wallets: Automate fee budgeting, track spending in real time, and receive Webhook alerts for transaction status and balance changes.

​
What Fee Station can do for you

​
Automatic gas fee handling

Fee Station can automatically cover gas fees for transactions initiated from MPC Wallets and Web3 Wallets. You can choose to cover fees only when the wallet balance is insufficient, or to always cover them. Once configured, the system automatically checks the condition and processes the gas fee without manual input. For more details about the chain support, please refer to Supported chains for gas fee payment.

​
How Auto Fueling works

To make sure a withdrawal address can pay its own on-chain fees, Fee Station may send a small amount of the native gas token (for example, on the order of 0.001 of the native token) to the address before processing the transaction. The cost of this top-up is deducted from your Fee Station balance. Depending on your configuration and available balances, the deduction may be settled from your USD or USD stablecoin balance even when a native gas token balance is present.

​
Unified fee settlement

In addition to covering gas fees, your Fee Station balance can also be used to settle all platform-related charges within Cobo Portal, including service fees and custody fees. You don’t need to maintain separate balances for each fee type. A single balance simplifies the billing process and gives you a clear, consolidated view of your spending.
Fee Station supports the following types of fees:

​
Flexible deposit options

You can deposit gas tokens directly, or simply deposit USD or USD stablecoins (such as USDT or USDC) as a unified balance. Fee Station will convert them into the required gas tokens at the time of transaction, avoiding the manual work of preparing tokens for each chain. For more details about supported gas token or stablecoin types, please refer to Supported token types.

​
TRON gas fee optimization with energy rental

Fee Station automatically leverages energy rental on the TRON network, prioritizing the use of energy to reduce the direct burning of TRX for gas fees. The entire process is fully automated, so you do not need to manage energy manually to benefit from fee optimization. With Fee Station enabled, TRON transaction fees can be reduced by up to 80%, and larger or high-frequency transactions can achieve even greater savings. For details on discounts for high transaction counts, please contact our sales team.

​
API and webhook integration

Fee Station offers standardized APIs and webhook support, allowing your system to access real-time fee data and receive timely notifications. This makes monitoring and operations tracking easier and more efficient. For more details, please refer to the Fee Station API and Webhook documentation.
