![]() You can click 'verify contract details' to see the address of the smart contract requesting access.This helps you make sure that the dapp you expect to be interacting with is actually the one requesting the approval. The dapp's name and web URL are displayed at the top. ![]() The token approval prompt that appears in MetaMask will look something like this: This is why token approvals are necessary: they enable the dapp to access and move your tokens on your behalf. However, clicking buttons such as 'Transfer', 'Deposit', or 'Move' won't do anything unless their dapp has your permission-as the wallet owner-to do so. Most platforms rely on you depositing or transferring your tokens to them for one reason or another. These prompts will often appear in MetaMask if you're a frequent user of decentralized exchanges (DEXs) and DeFi in general. In short: permission for a dapp to access and move a specific type of token from your wallet. That's why it's critical you know exactly what you're signing up for when you confirm token approvals. In web3, and especially with a self-custodial wallet like MetaMask, you're firmly in control and hold ultimate responsibility for everything you do. Token approvals are among the most common of the transaction types you'll encounter, and learning about them is therefore essential. The challenge is that much of the information displayed on these screens is either not designed to be human-readable-such as the long hexadecimal numbers we recognize as account or contract addresses-or, at best, is difficult to decipher. Understanding what they are and how to interpret their meaning is an important part of staying safe in web3. Across web3, you'll encounter a range of transaction types, each of which is identifiable in MetaMask at the point of confirming the transaction.
