If you are worried about what you've approved you can check and revoke permission on revoke.cash/ created by @RoscoKalis. If the site is down, you can also use revokefork.com/ redeployed by @anishagnihotri to compensate for the heavy demand. (6/8)
In addition, you can also revoke permission on Etherscan directly on the contract. They also have a beta tool similar to Revoke at etherscan.io/tokenapprovalch…. Although in my experience they missed a few collections I had previously approved. (7/8)
