Foundation
In Web3, a wallet often acts as an identity and signing tool. Connecting usually exposes a public account; changing blockchain state requires a separate signature or transaction. To understand Web3 & DApps, place the concept inside a real on-chain workflow: where the information comes from, what the user confirms, how the network records the result, and which outcomes cannot normally be reversed by a wallet provider. This makes inconsistencies easier to spot across different apps and networks.
Key mechanics
Message signatures can be used for login or intent, while transaction signatures can alter on-chain state. Both deserve careful review. In practice, start with the intended outcome and then verify the relevant fields. If an address, network, contract or permission connected to Web3 & DApps cannot be explained, stop rather than accepting the default button. Public blockchain data can often be used as a second source of verification.
A practical way to check
Separate what you can verify publicly from what must remain secret. Network names, public addresses, transaction hashes and contract addresses can be checked against public blockchain data. Seed phrases and private keys should never be disclosed for this purpose.
Practical decisions
Token approvals give contracts spending permission. Check the spender, asset, amount and purpose rather than accepting by habit. Security is not a single “perfect protection” switch. It comes from repeatable habits: trusted entry points, independent checks, least-necessary permissions, offline protection of secret credentials, and a willingness to reject abnormal requests.
imtoken staff will not ask for your seed phrase or private key. Review the address, network and request before any transfer, signature or approval.
Important considerations
Unknown websites, surprise airdrops and “wallet verification” pages should never require your seed phrase, and unclear signing requests can simply be rejected. After an action, verify that the result matches the intention. Save non-secret references such as the transaction hash, network and public address for troubleshooting, while keeping seed phrases, private keys and verification codes private.
