Revoke tokens approval
To remove a dApp access to your wallet's tokens, you can revoke approvals previously granted. An easy way to do it would be to use Revoke, for example.
- Head over Revoke, click "Connect wallet" and select Metamask.
Metamask will open - connect your target account.
Click the "Revoke" button on the right side for the token of your choice.
Sign the transaction on Metamask, and wait for confirmation on Revoke's UI.
After a few seconds, the targeted entry should disappear from the UI - you're done!
Revoking means changing the Approval amount back to 0 - it's a transaction you'll have to sign, and it'll therefore consume some gas.
