Smart Accounts provide flexible security and control through various policy mechanisms. This guide explains the key policies and how to use them effectively.

​
Policies

Policies are defined when creating a new smart account using the /smart-accounts endpoint. The policies object contains the following key components:

​
Authorities

Authorities are the entities that can perform actions on the smart account. Each authority has a set of permissions that define what actions they can take.

​
Permission Types

The following permissions can be assigned to authorities:
  • CAN_INITIATE: Required to propose new intents
  • CAN_VOTE: Required to approve intents
  • CAN_EXECUTE: Required to execute approved intents

​
Example Configuration

{
  "policies": {
    "authorities": [
      {
        "address": "EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v",
        "permissions": ["CAN_INITIATE", "CAN_VOTE", "CAN_EXECUTE"]
      },
      {
        "address": "7xKXtg2CW87d97TXJSDpbD5jBkheTqA83TZRuJosgAsU",
        "permissions": ["CAN_VOTE"]
      }
    ]
  }
}

​
Threshold

The threshold defines how many authorities must approve an intent. This creates a flexible M-of-N multisig setup.

​
Rules

  • Must be greater than 0
  • Cannot exceed the number of signers with CAN_VOTE permission
  • Maximum value is 10

​
Example Configuration

{
  "policies": {
    "authorities": [...],
    "threshold": 2
  }
}

​
Admin Control

Admin control is an optional security feature that restricts who can modify Smart Account settings. When an admin address is set, only that address can modify the account’s configuration.

​
Example Configuration

{
  "policies": {
    "authorities": [...],
    "threshold": 2,
    "admin_address": "EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v"
  }
}

​
Creating a Smart Account with Policies

To create a smart account with policies, use the /smart-accounts endpoint: 
POST /api/v0/grid/smart-accounts
{
  "policies": {
    "authorities": [
      {
        "address": "EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v",
        "permissions": ["CAN_INITIATE", "CAN_VOTE", "CAN_EXECUTE"]
      },
      {
        "address": "7xKXtg2CW87d97TXJSDpbD5jBkheTqA83TZRuJosgAsU",
        "permissions": ["CAN_VOTE"]
      }
    ],
    "threshold": 2,
    "admin_address": "EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v"
  }
}

​
Retrieving Smart Account Policies

To retrieve the policies for a smart account, use the /smart-accounts/{smart_account_address} endpoint with the policies query parameter: 
GET /api/v0/grid/smart-accounts/{smart_account_address}?policies=true

​
Best Practices

  1. Authorities
    • Separate duties between authorities
    • Limit CAN_INITIATE to trusted parties
    • Have multiple CAN_EXECUTE authorities for redundancy
  2. Threshold
    • Choose threshold based on security needs
    • Consider operational efficiency
    • Plan for key rotation
  3. Admin Control
    • Use admin control for managed accounts
    • Keep admin keys secure and offline
    • Consider using a multisig as admin
