Start with the Core Concepts
Web3 activity usually starts with connecting an account and may continue into message signatures, transaction signatures, token approvals or contract calls. The practical way to understand Web3 & DApps is to place it inside a real user journey rather than memorize isolated terms. 理解连接、签名、授权、合约交互与退出连接 should be checked before an action, during confirmation and again after completion. Verify the entry point and network first, read addresses, permissions, fees and request details at confirmation, then use on-chain records to validate the outcome.
Many mistakes around Web3 & DApps begin with information that looks familiar: similar network names, address formats, token symbols or interface layouts. Prefer details that can be independently checked, such as the full domain, network name, contract address, transaction hash and a matching block-explorer record, instead of relying on icons, nicknames or screenshots. For Web3 & DApps, break the task into small points that can be verified rather than continuing while the network, address, permission or transaction state is still unclear.
Pre-action check
Confirm that the page and network match the task, then review public addresses, assets, fees or permission details. A familiar interface is not a reason to skip the request details of a third-party DApp or smart contract.
How the Mechanism Works
Connection and approval are different concepts: a connection shares selected account information, while an approval may grant a contract authority over a token allowance.

imtoken treats user review as the final decision point for Web3 & DApps.

DApps, smart contracts, networks and third-party services each introduce their own risk boundaries.

Practical Decision-Making
Review the domain, request target, permission scope and transaction details every time. Remove connections and approvals you no longer need. imtoken treats user review as the final decision point for Web3 & DApps.

If the result differs from what you expected, preserve non-secret details such as the transaction hash, network and public address, then begin troubleshooting from on-chain state. Never send recovery information to someone claiming to provide support, and do not sign an unfamiliar request simply because it is presented as a fix.
