Importance of Contract Call Permissions

  • Security: Properly setting your permissions helps prevent unauthorized access to your assets.

  • Control: You can specify which contracts have access to your wallet, giving you full control over your assets.

  • Functionality: Grants access to certain functions you may need from decentralized applications (dApps).

    • Five Productivity Tips for Setting Up Contract Call Permissions

  • Review Smart Contract Information

    • Before granting permissions, always conduct thorough research on the smart contracts you are interacting with.

    Tip: Check the contract's code on platforms like Etherscan. Look for audits and reviews.

    *: If you're considering using a DeFi protocol, ensure it has undergone a thirdparty audit to verify its security and integrity.

  • Utilize ImToken's BuiltIn Features

    • imToken provides several tools to help manage contract call permissions effectively.

    Tip: Use the “Set Permissions” feature in the wallet interface.

    : When you first connect to a new dApp, imToken will prompt you to set permissions. Take the time to selectively grant permissions based on your interaction needs.

  • Limit Permissions to Intermittent Use

    • Avoid giving permanent permissions to contracts unless necessary. Instead, limit them to specific functions, particularly when interacting with new contracts.

    Tip: Set a timebound permission or scope of interactions.

    : If you are using a contract for a onetime transaction, opt for a temporary permission that automatically retracts after completion.

  • Regularly Review and Revise Permissions

    • Make it a routine to review your granted permissions and remove any that are no longer relevant or necessary.

    Tip: Set a monthly reminder to check your permissions.

    : After participating in a shortlived token sale, revoke its access once your transaction is complete to reduce risk.

  • Stay Informed about Updates and Vulnerabilities

    • Smart contracts can be upgraded or face vulnerabilities over time, leading to changes in how permissions should be managed.

    Tip: Follow the project’s official channels for updates and alerts regarding security issues.

    : Subscribe to the project’s Discord or Telegram for realtime updates on potential contract vulnerabilities or security breaches.
