Core security principles
Signatures can prove account control or authorize on-chain actions. Different signature types have different consequences, so button labels alone are not enough. For Signature Requests, it is useful to understand how 消息签名, 交易签名 and Typed Data relate before taking action. A wallet interface presents on-chain information; the actual outcome is determined by the selected network, address, transaction or contract. When a balance, transaction state or approval looks unexpected, verify the underlying on-chain information instead of relying on a single interface message.
A repeatable review order helps: first verify 消息签名, then 交易签名, and finally Typed Data. A consistent sequence reduces the chance of skipping an important detail simply because the interface feels familiar.
Common risk scenarios
In practical use, treat 交易签名 as an early checkpoint, then review Typed Data and 请求来源. If a transfer or contract interaction is involved, confirm the destination, asset type and expected network fee before submitting. For an unfamiliar network, token or DApp, verify the source and parameters first. A small test can be useful when the path is new and the consequences are difficult to reverse.

How to recognize and respond
When investigating a Signature Requests issue, keep verifiable details such as the address, network, 请求来源, 资产影响 and transaction hash. On the correct block explorer, a transaction hash can show whether a transaction was included, failed or interacted with a specific contract. If an interface display differs from the chain record, make sure you are checking the correct network and asset contract before drawing conclusions.

Everyday security checklist
From a security perspective, no legitimate support flow should require you to send a seed phrase, private key or verification code. Be especially careful with 消息签名 and 资产影响: verify address, network and amount before transfers; review each signature request; inspect the spender and allowance before approvals; and consider revoking permissions you no longer use. On-chain transactions are generally not reversible by a wallet provider, and third-party DApps or smart contracts may carry technical or fraud risks.

Seed phrases and private keys should remain under your own custody. Official staff will never ask for them or for verification codes. Third-party DApps, smart contracts, bridges and staking services may carry risks; decide based on your own circumstances.
