# Create contract call policy

> Understand the steps to create contract call policies in Cobo Portal, ensuring secure and compliant transactions.

<Info>Due to the Bybit security incident, Safe Wallet has suspended third-party delegate call services. As a result, Cobo's Smart Contract Wallets and related services (including on-chain transaction policies) are temporarily unavailable. However, existing wallets and on-chain transaction policies can still be used. Recovery timeline will be announced later.</Info>

<Note>Prerequisite: Please make sure that you have already [created](/en/portal/risk-controls/on-chain-tx-type) a Delegate Key and added assets to the selected wallet.</Note>

1. Log into [Cobo Portal](https://portal.cobo.com/login).
2. Click **Wallets** in the left sidebar, then select **Smart Contract Wallets**.
3. Click on the Safe\{Wallet} you have connected to or created on the Cobo Portal.
4. Switch to the On-Chain Transaction Policies tab and click <img src="https://mintcdn.com/cobo-6/tlCgUniYtQytnL97/en/images/risk-controls/create_policy.svg?fit=max&auto=format&n=tlCgUniYtQytnL97&q=85&s=1cb5b3df0b555ede908be589c00d4270" className="icon" width="109" height="32" data-path="en/images/risk-controls/create_policy.svg" />.
5. Enter a name for your on-chain transaction policy, with a maximum of 50 characters.
6. Select the Delegates to which this policy will apply. Note that each Delegate is an EOA address. Upon successful creation of an on-chain transaction policy, your selected Delegates will also be authorized to perform single-signature operations such as token transfers and custom contract calls.

* My Wallets: Select addresses from your MPC Wallets (Organization-Controlled) and designate them as your Delegates.
* Other Addresses: Manually enter EOA addresses to designate them as your Delegates.

7. Click **+ Add Condition** to select an If condition.

* Token approvals: You can specify which tokens can be spent, the spenders authorized to spend them, the maximum spending amount per transaction or per specified time period.
* Token transfers: You can specify which types of tokens can be transferred, the receiving addresses, the maximum transfer amount per transaction or per specified time period.
* Custom contract calls: You can specify the smart contract to call, the functions to use, and the parameters to include in each transaction.

8. (For token approvals only) Please fill in the following fields:

* Tokens: In the drop-down menu, click **Include** to select the list of tokens approved for spending.
* Amount: In the drop-down menu, select **Any Amount** if there is no upper limit on the number of tokens approved for spending. Select **Count by Number** to specify the exact number of tokens approved for spending.
* Frequency: In the drop-down menu, select **No Frequency Limit** if the maximum spending amount applies to the total number of transactions from the approved spenders. Select **Per Transaction** if the maximum spending amount applies to each transaction, or select **By Hour** to specify the number of hours for which the maximum spending amount applies.
* Approved Spenders: In the drop-down menu, select **Any Address** to allow any address to spend the approved tokens. Select **In Address Lists** to restrict spending to an address added to your [Address Lists](/en/portal/risk-controls/address-list).
  * Please note that if you need to edit the approved spender associated with a submitted on-chain transaction policy, you must first navigate to Transaction Policies > Address Lists to update the address. Then, head to Smart Contract Wallets > On-Chain Transaction Policies > Current to modify the associated on-chain policy and resubmit it for multi-sig confirmation.

10. (For custom contract calls only) Select whether the smart contract call will be made at the contract level, method level, or parameter level. Then, fill in the corresponding fields:

* Contract-Level:
  * If you have added target contracts before, search for them in the drop-down menu. Otherwise, key in the contract address in the text box within the drop-down menu and click **Add Address**.
* Method-Level:
  * If you have added target contracts before, search for them in the drop-down menu. Otherwise, key in the contract address in the text box within the drop-down menu and click **Add Address**.
  * Select the methods you need. If the displayed methods are incorrect, click **Edit Contract ABI**. In the pop-up window, either edit the text manually or upload a JSON file from your device.
* Parameter-Level:
  * If you have added target contracts before, search for them in the drop-down menu. Otherwise, key in the contract address in the text box within the drop-down menu and click **Add Address**.
  * Select a method from the drop-down menu. If the displayed methods are incorrect, click **Edit Contract ABI**. In the pop-up window, either edit the text manually or upload a JSON file from your device.

11. Review the Then condition and click **Next**. Note that setting up an on-chain transaction policy for Smart Contract Wallets is similar to granting on-chain permissions. As a result, any on-chain transaction triggered under this policy will be automatically approved.
12. If you want to make edits to the policy, click **Cancel**.
13. A multi-sig confirmation from Safe\{Wallet} signers is required. Click **Submit** to initiate the multi-sig transaction. Alternatively, click **Add to Queue** and later navigate to **Smart Contract Wallets** > **On-Chain Transaction Policies** > **Queue** to batch-submit all multi-sig confirmation requests in the queue.
