What is Approve?

Approve, means granting a third party access to a portion of your assets which can be an ordinary personal account or a contract account without revealing your private key or password to them completely.

For example, if you use a decentralized finance (DeFi) application, you may need to approve your wallet for the application to perform transactions on your behalf. During this process, your wallet generates a special digital signature that proves you have approved the application to execute specific actions. However, it doesn’t mean that the application can freely control your wallet or access all your assets unless you have explicitly approved it.

This process is usually implemented through smart contracts, which are self-executing programs running on the blockchain. Once approval is granted, the smart contract can perform specific tasks on your behalf, such as transferring assets, but only within the scope you have approved.

What scenarios will use Approve in the process of using the wallet?

The ordinary transfers won’t ask the Approve in the process of using the wallet; Only when it involves interacting with the contract (DApp, DeFi, etc.), the Approve operation will be performed when the contract needs to be approved. Therefore, when you are in the process of using the wallet, and the following interface appears, you are asked about the Approve. You must be more careful and confirm whether the current link you are visiting is safe and credible. If not, stop operating!!

How to manage/cancel the Approval?

Attention, any operation on-chain needs to pay the gas fee, and it’s charged by the public chain.

5. It is recommended to regularly check the approval status to ensure the security of your assets.

How to prevent Approve Scams?

  1. Don’t play DApps from unknown sources, don’t play DApps have no open-sourced, and don’t play DApps have no audit reports and are not from trustable teams.
  2. Regularly use DeBank, Cointool, and other tools to cancel the approval.
  3. Create a new wallet. After the approval and other operations are completed, transfer the Token to the new wallet address, which is relatively safe because there is no approval history (Attention: the cancel the approval doesn’t mean absolutely safe, there is no tools on the market that can guarantee a complete cleanup.)
