Overview

Creating smart contracts and configuring auto sweeping rules through the Custody web interface ensures that the system executes corresponding auto sweep operations according to the rules during the sweeping process. Simultaneously, by authorizing sub-wallets for sweeping contract in the App, you can precisely determine which sub-wallets have the right to sweep assets.

Key Steps and Considerations

ChainUp Custody platform only supports Web3 sub-wallets for sweeping.

Each sub-wallet and token that needs sweeping must be authorized in advance.

It is strongly recommended not to configure the same asset strategy for both the Sweep ERC-20 Tokens feature and the Sweep All Coins feature simultaneously. If an error occurs, the system will execute the sweeping operation configured earliest based on the time of your operation.

​
Configure Auto Sweeping Rule Process

Configuring auto sweeping rules involves three processes:

  1. Create and publish a sweeping contract.

  2. Configure sweeping assets.

  3. Contract authorization.

​
Step 1: Create and Publish a Sweeping Contract

1

Create and Publish a Sweeping Contract

In the MPC web interface, select “Sweep ERC-20 Tokens,” and click ”+” to create a sweeping contract.

2

Edit Auto Sweep Rules

  1. Enter the rule name, select the main chain, and confirm the sweeping address.

  2. Choose the aimed sub-wallet to receive assets.

3

Sign and Publish the Contract

The private key holder signs using the Custody App to scan the code, and the auto sweep rule is successfully published.

​
Step 2: Configure Sweeping Assets

1

Edit Sweeping Threshold

Click Edit button on the Sweep ERC-20 Tokens page, and click ”+” on the edit page to add tokens.

2

Edit Sweeping Threshold

After adding the tokens that need sweeping, click “Edit Threshold” to set the sweeping threshold: trigger auto sweeping when the asset amount exceeds the threshold.

​
Step 3: Contract Authorization

1

Open Sweep Tokens Feature

Log in and open the Custody App, switch to the MPC system, and open the “Discover - Sweep Tokens” function.

2

Authorization Management

Click on “Authorization Management” . The private key holder needs to sign with the private key to authorize the sub-wallet.

Key Steps and Considerations

For each type of asset to be swept in the sub-wallets requiring auto sweeping via ‘sweep,’ individual authorizations are necessary. For sub-wallets that do not require sweeping, simply deselect the ‘sweep’ option.

Please use the Custody App’s [Discover] - [Sweep Tokens] function, click to select the main wallet that has configured the sweeping contract for authorization.
