Auto token sweeping helps you automatically consolidate assets from multiple deposit addresses into a designated address, improving asset management efficiency. To ensure sweep transactions behave as expected, you can configure several settings for a wallet, including:
  • Deposit address transaction capability
  • Network fee limits for sweep transactions
  • Automatic RBF (Replace-By-Fee) acceleration for sweep transactions

​
Prerequisites

​
Enable deposit address transactions

After auto token sweeping is enabled, deposit addresses are, by default, only used to receive assets and to initiate sweep transactions to the designated sweep-to address. They cannot initiate withdrawals, contract calls, staking, OTC trades, or financial product transactions, and they cannot be used as delegate addresses for smart contract wallets. If you need to restore full on-chain transaction capabilities for deposit addresses, you can manually enable deposit address transactions according to the following steps:
  1. In the wallet list, find the target wallet.
  2. In the wallet settings page, click the Auto-Sweep Settings icon Auto-Sweep Settings.
  3. On the Auto-Sweep Settings page, click the button next to Deposit Address Transactions. Auto-Sweep Settings
  4. In the Enable deposit address transactions dialog, click Confirm, and complete multi-factor authentication (MFA).
After successful verification, the system initiates the corresponding approval workflow. Once approved, the change takes effect. After this feature is enabled, deposit addresses have the same transaction capabilities as sweep-to addresses. When initiating an on-chain transaction (such as a transfer or a contract call), you can choose to pay the gas fee from the wallet address or have it covered by Fee Station for automatic gas fee top-up and unified settlement.

​
Modify network fee limits for sweep transactions

By default, the system sets network fee caps for BTC and ETH sweep transactions. If the estimated fee exceeds the limit, the sweep transaction will not be executed to prevent excessive fees during periods of network congestion. You can adjust these fee limits based on your business needs according to the following steps:
  1. In the wallet list, find the target wallet.
  2. In the wallet settings page, click the Auto-Sweep Settings icon Auto-Sweep Settings.
  3. On the Auto-Sweep Settings page, click Edit Configuration under Sweep Transaction Network Fee Limits. Auto-Sweep Settings
  4. Enter the fee limit values for BTC and ETH.
  5. Click Submit, and complete multi-factor authentication (MFA).
After successful verification, the system initiates the corresponding approval workflow. Once approved, the updated fee limits take effect.

​
Automatically trigger RBF acceleration for sweep transactions

If a sweep transaction is not confirmed within a specified time, you can configure to allow Cobo automatically send a Replace-By-Fee (RBF) transaction to speed up confirmation according to the following steps:
  1. In the wallet list, find the target wallet.
  2. In the wallet settings page, click the Auto-Sweep Settings icon Auto-Sweep Settings.
  3. On the Auto-Sweep Settings page, click the button next to Auto RBF for Sweep Transactions. Auto-Sweep Settings
  4. Configure the trigger time and maximum number of attempts.
  5. Click Submit, and complete multi-factor authentication (MFA).
After successful verification, the system initiates the corresponding approval workflow. Once approved, the RBF acceleration configuration takes effect. For more details on sweep behavior, fee strategies, and transaction execution, see the auto token sweeping introduction.
