Build a repeatable security routine
Signature Requests: Review Before You Sign is best approached as a sequence of checks rather than a promise that any wallet can remove all risk. Identify who is asking you to act, what permission is being requested, which network or contract is involved, and what will change if you approve; in Signature Requests: Review Before You Sign, read this specifically alongside “Build a repeatable security routine” and message signatures. imtoken staff will not ask for a seed phrase, private key, or verification code; in Signature Requests: Review Before You Sign, read this specifically alongside “Build a repeatable security routine” and message signatures. Those credentials remain under the user’s control and should never be uploaded, pasted into chat, or shown through remote-access software; in Signature Requests: Review Before You Sign, read this specifically alongside “Build a repeatable security routine” and message signatures. Do not treat an interface success message as the final answer for Signature Requests: Review Before You Sign. Use message signatures, transaction signatures and request origin to confirm that the expected change occurred on the intended network.
Recognize risks around message signatures
Problems involving message signatures often begin with a misleading page, an urgent message, or a request that does not match the task you intended to perform. Re-check the domain, the connected account, and the reason for the request; in Signature Requests: Review Before You Sign, read this specifically alongside “Recognize risks around message signatures” and transaction signatures. Promises of rewards, account “verification,” urgent upgrades, or support assistance should never be used as a reason to skip basic checks; in Signature Requests: Review Before You Sign, read this specifically alongside “Recognize risks around message signatures” and transaction signatures. If “Recognize risks around message signatures” is unclear, stop before approving and return to the basics of transaction signatures and request origin, then verify the result with a transaction hash, contract address or block record where applicable.
Review transaction signatures and request origin before acting
When reviewing transaction signatures and request origin, separate the object, the scope, and the consequence. The object may be an address, contract, device, or account; the scope may be a single transaction or a continuing approval; the consequence is what can happen after confirmation; in Signature Requests: Review Before You Sign, read this specifically alongside “Review transaction signatures and request origin before acting” and request origin. If the interface does not give enough context, stop and verify the address, transaction, or contract through the correct blockchain explorer; in Signature Requests: Review Before You Sign, read this specifically alongside “Review transaction signatures and request origin before acting” and request origin. A durable routine for Signature Requests: Review Before You Sign is to make request origin a first-pass check, use signature contents as a second check, and rely on verifiable information related to malicious signatures rather than interface assumptions.
- A request asks for recovery credentials or a verification code.
- The domain, account or permission does not match your task.
- Urgency or rewards are used to pressure you into approving.
What to do when something looks wrong
If activity appears suspicious, avoid repeated clicks in the same session; in Signature Requests: Review Before You Sign, read this specifically alongside “What to do when something looks wrong” and signature contents. Disconnect unnecessary DApps, review recent transactions and token approvals, and move to a trusted device if the current environment may be compromised; in Signature Requests: Review Before You Sign, read this specifically alongside “What to do when something looks wrong” and signature contents. Blockchain transactions are generally not something a wallet provider can unilaterally reverse, so the useful goal is to limit further exposure rather than trust anyone promising a guaranteed recovery; in Signature Requests: Review Before You Sign, read this specifically alongside “What to do when something looks wrong” and signature contents. This part of Signature Requests: Review Before You Sign should be read together with the surrounding workflow: signature contents affects how you interpret malicious signatures, while declining requests helps confirm the state after the action.
A practical security checklist
A consistent routine can cover signature contents, malicious signatures, and most other Web3 interactions: use a trusted device, confirm the site, verify the network and destination, read each signature or approval, check the amount and fee, then review the transaction hash afterwards. Remove permissions that are no longer needed and keep recovery credentials offline; in Signature Requests: Review Before You Sign, read this specifically alongside “A practical security checklist” and malicious signatures. For Signature Requests: Review Before You Sign, connect malicious signatures with declining requests and message signatures; the important part is the relationship between those concepts and the on-chain evidence you can verify afterward.
The boundaries that should not change
The durable rules are simple: never share a seed phrase or private key, treat third-party DApps and smart contracts as independent risk sources, verify the address/network/amount before a transfer, and review approval scope before granting access; in Signature Requests: Review Before You Sign, read this specifically alongside “The boundaries that should not change” and declining requests. imtoken provides wallet tools and educational material; it does not guarantee the security of third-party contracts, network availability, or asset prices; in Signature Requests: Review Before You Sign, read this specifically alongside “The boundaries that should not change” and declining requests. When working through “The boundaries that should not change,” check the source, network, request details and resulting state in that order, with extra attention to declining requests and message signatures.
Security and risk reminder
Seed phrases and private keys are controlled by the user. imtoken will never ask for them. Blockchain transactions are generally irreversible by a wallet provider, and third-party DApps, smart contracts, network conditions and digital-asset prices can introduce additional risk.
