Optimizing metamask permissions: a guide to approve or give permission to access tokens
When creating a decentralized change (DEX) with multiple liquidity providers and users, ensuring that the necessary permissions are configured correctly to become crucial. In this article, we will explore how to approve or give permission to access your tokens using solidity in Metamask.
Understanding Metamask Permissions
In Metamask, permissions are used to control access to their token balances and accounts. When you create a contract at Blockchain Ethereum, it is implemented on the Ethereum network. To interact with this contract, you need to provide the necessary permissions. These permissions can be configured using solidity.
Current edition: permission that does not display
You have found a problem where permission settings are not displayed correctly in your metamask wallet. Probably, this is due to some reasons:
- Permission configuration may have been updated or accidentally changed.
- The implementation of the contract is not visible because the address ‘0x’ associated with it is absent or incorrect.
Solution: Update Permissions Setup
To correct this problem, you need to update your permissions setting on Metamask. Here are the steps:
- Open metamask : Open the metamask on your device and browse to your wallet.
- Select Contract : Select the contract that was implemented in the Ethereum network (for example,
0x ...).
- Permissions Guide
: On the Permissions tab, click the “Add Permission” button.

Concession of Permissions: Approving or giving access
After updating your permissions configuration, you need to grant the necessary permissions to access your token balances and accounts. Here are some common use cases:
- Grant permission only reading for a user to view your balance.
* Select “Reading Only” as the type of permission.
* Enter the address 0x of the user associated with the contract (for example,0x ...).
* Define the level of permissions as “reading only”.
- Grant permission only by recording for a user to update your balance.
* Select “Write only” as the type of permission.
* Enter the address 0x of the user associated with the contract (for example,0x ...).
* Define the level of permissions to “write only”.
- Grant full access permission to a user to access your balance and make transactions.
* Select “All Access” as the type of permission.
* Enter the address 0x of the user associated with the contract (for example,0x ...).
* Set the level of permissions as “all access”.
Example of use of use: Granting permission only reading to a user
Suppose you want to grant permission only reading to allow users to view your balance, but also prevent them from making transactions.
- Open Metamask.
- Select the contract that was implemented in the Ethereum network (for example,
0x ...).
- On the Permissions tab, select “Reading Only” as the type of permission.
- Enter the address
0xof the user associated with the contract (for example,0x ...) and set the level of permissions as” reading only “.
- Save your changes.
By following these steps, you can optimize your Metamask permissions configuration to give you access to your tokens, ensuring that only authorized users are allowed to view their balances and make transactions.
