Signature Requests

Core security principles

Wallet actions are rarely explained by a single button; addresses, networks, signatures, permissions, and on-chain state all contribute to the outcome. Using message signatures as a starting point, first define the practical problem it solves, then connect it with transaction signatures and domain checks. This prevents terminology from becoming detached from the decisions you actually make in a wallet interface.

Blockchains make activity verifiable, but verifiability is not the same as automatic safety. Critical fields and permission scopes still require human review. The goal of Signature Requests is not to make every action faster. It is to make each step explainable: verify the source, identify the intended target and parameters, then decide whether to continue. This sequence is especially helpful when a new concept first appears in a real transaction.

How risky situations arise

A useful review habit is to separate three questions: what you intend to do, where the request came from, and what the action will change on-chain. Whenever transaction signatures is involved, review the information related to request details at the same time. If the target, network, permission, or request origin differs from what you expected, do not confirm simply because the interface presents a familiar button. Keep enough context around malicious signatures to verify the outcome later.

Do not judge success from interface color alone. When appropriate, confirm the network, transaction hash, and resulting on-chain state with a block explorer. For troubleshooting, classify the problem before retrying. Determine whether it is a display issue, a network condition, an on-chain confirmation issue, or a third-party service problem. Then check message signatures, domain checks, and malicious signatures in that order rather than repeatedly submitting the same request.

• transaction signatures
• domain checks
• request details

Signals that deserve scrutiny

Blockchains make activity verifiable, but verifiability is not the same as automatic safety. Critical fields and permission scopes still require human review. The goal of Signature Requests is not to make every action faster. It is to make each step explainable: verify the source, identify the intended target and parameters, then decide whether to continue. This sequence is especially helpful when a new concept first appears in a real transaction.

If an action cannot be explained clearly, stopping before confirmation is usually safer than repeatedly retrying, especially for transfers, signatures, and approvals. Asset and permission changes can have irreversible consequences. A wallet normally cannot unilaterally reverse a confirmed on-chain transaction, and third-party DApps or smart contracts may introduce independent risks. Any confirmation involving request details should therefore be based on a clear understanding of what will change.

What to do when something looks wrong

Do not judge success from interface color alone. When appropriate, confirm the network, transaction hash, and resulting on-chain state with a block explorer. For troubleshooting, classify the problem before retrying. Determine whether it is a display issue, a network condition, an on-chain confirmation issue, or a third-party service problem. Then check message signatures, domain checks, and malicious signatures in that order rather than repeatedly submitting the same request.

The strongest day-to-day habits are simple and repeatable: verify the source, target, network, amount, and any record that can later be independently checked. After completion, return to transaction history or an appropriate on-chain tool to verify the result. Also review whether any connection or approval is still needed. Over time, understanding the relationship between transaction signatures and malicious signatures is more useful than memorizing a single sequence of clicks.

Security boundaries and responsibility

The strongest day-to-day habits are simple and repeatable: verify the source, target, network, amount, and any record that can later be independently checked. After completion, return to transaction history or an appropriate on-chain tool to verify the result. Also review whether any connection or approval is still needed. Over time, understanding the relationship between transaction signatures and malicious signatures is more useful than memorizing a single sequence of clicks.

imtoken staff will never ask for a seed phrase, private key, or verification code. Keep recovery material under your own control, review addresses, networks and amounts before transfers, and treat every third-party DApp or smart contract as a separate risk decision.
