What a browser connection means
To understand imtoken Web, place what a browser connection means inside the full on-chain workflow instead of treating it as an isolated label. The practical point is to verify what a browser connection means in the context of the selected blockchain network. The user should compare the request with the intended address, asset, account or contract before confirming. A wallet can organize information and submit requests, but the selected network and the blockchain determine the final state. On-chain state and a transaction hash provide stronger evidence than a delayed interface alone. Third-party DApps, services and smart contracts can introduce risks that need separate review. If the interface does not match your expectation, verify the network, address, contract and on-chain record before taking another action.
A practical way to approach what a browser connection means is to use a consistent review sequence. First, the practical point is to verify what a browser connection means in the context of the selected blockchain network. Next, the user should compare the request with the intended address, asset, account or contract before confirming. After a transaction, signature or approval is submitted, on-chain state and a transaction hash provide stronger evidence than a delayed interface alone. Finally, third-party dapps, services and smart contracts can introduce risks that need separate review. This sequence gives each confirmation a clear reason and helps reduce wrong-network transfers, address mismatches, unnecessary permissions and repeated actions caused by a delayed interface.

The boundaries of signatures
To understand imtoken Web, place the boundaries of signatures inside the full on-chain workflow instead of treating it as an isolated label. Check the domain and the intended network before connecting. Connection, signature, transaction and approval are separate decisions. A wallet can organize information and submit requests, but the selected network and the blockchain determine the final state. Each request should be reviewed on its own rather than approved automatically. End a session by disconnecting and reviewing any new approvals. If the interface does not match your expectation, verify the network, address, contract and on-chain record before taking another action.

Approvals and permissions
To understand imtoken Web, place approvals and permissions inside the full on-chain workflow instead of treating it as an isolated label. Approvals can give a contract permission to use tokens within a defined scope. The spender or operator address and amount should be checked before signing. A wallet can organize information and submit requests, but the selected network and the blockchain determine the final state. Disconnecting a DApp does not automatically revoke an on-chain approval. Unused permissions can be reviewed and revoked with a new on-chain transaction. If the interface does not match your expectation, verify the network, address, contract and on-chain record before taking another action.

Checks after a session
To understand imtoken Web, place checks after a session inside the full on-chain workflow instead of treating it as an isolated label. The practical point is to verify checks after a session in the context of the selected blockchain network. The user should compare the request with the intended address, asset, account or contract before confirming. A wallet can organize information and submit requests, but the selected network and the blockchain determine the final state. On-chain state and a transaction hash provide stronger evidence than a delayed interface alone. Third-party DApps, services and smart contracts can introduce risks that need separate review.
