Ethereum Token Approve Online

About Token Approval Tool

The Token Approval tool is a free and open-source utility designed to help users manage their token approvals on Ethereum and other EVM-compatible blockchains. This tool provides a simple and secure way to view and revoke token allowances, enhancing the security of your digital assets.

What is Token Approval?

Token approval, also known as token allowance, is a feature in ERC-20 and similar token standards that allows smart contracts to spend tokens on behalf of the token holder. While this is necessary for many DeFi applications, it can pose security risks if not managed properly.

Key Features

  • View Approvals: Easily see all current token approvals for your address
  • Revoke Allowances: Quickly revoke unnecessary or risky approvals
  • Multi-Chain Support: Compatible with Ethereum and other popular EVM chains
  • Security-Focused: All operations are performed locally for maximum security
  • User-Friendly Interface: Intuitive design for both beginners and experienced users

How to Use

  1. Connect Wallet:

    • Connect your Web3 wallet (e.g., MetaMask) to the tool
    • Ensure you're connected to the correct network

  2. View Approvals:

    • The tool will automatically display all token approvals for your address
    • Review the list of approved contracts and allowance amounts

  3. Revoke Approvals:

Why Use This Tool?

  • Enhanced Security: Regularly revoking unnecessary approvals reduces the risk of potential exploits
  • Better Asset Management: Gain a clear overview of which contracts have permission to spend your tokens
  • Peace of Mind: Ensure that old or unused DApps no longer have access to your funds
