On this page, you can view every smart contract that you've approved with your wallet.
An ‘Approve’ transaction grants a smart contract the permission to interact with the tokens in your non-custodial crypto wallet.
The total allowance value indicates the total amount in your wallet that can be accessed by smart contracts that you’ve previously approved.
You can select the smart contract under ‘Approved Spender’ to view the smart contract on a block explorer.
For example, this smart contract (0x051DC16b2ECB366984d1074dCC07c342a9463999) is referring to the Krystal Router, one of the smart contracts that you’ll use on our platform.
You can choose to revoke any smart contract by clicking on the revoke button.
Gas fees are needed to process this ‘revoke access’ transaction, so don’t forget to have some of the native tokens in your wallet.
Once the transaction is confirmed, the smart contract is no longer able to interact with your token balance.
