# Control of Your Wallet

### Security of your funds

When using dApps like Uniswap or OpenSea, you must grant them permission to spend your tokens and NFTs.\
If you don’t revoke these allowances, the dApp can spend your tokens indefinitely.\
Using this function, you can regain control of the situation by revoking your authorisations.
