Revoke Allowance

When using dapps like Uniswap, OpenSea or a custom smart contract, you have to grant them permission to spend your tokens and NFTs, for example if you want to execute a swap function. This is called an allowance. If you don't revoke these allowances, the dapp can spend your tokens forever. Take back control by revoking your allowances.
