Verify the DApp entry point
Before opening a DApp, verify the domain and why you are there. Search ads, unsolicited messages and urgent promotions can lead to lookalike sites. A wallet connection only establishes limited account interaction; it does not validate later requests. For Signature Requests, apply this principle to the specific fields and sequence described on this page.
Understand signature types
Wallets can show message signatures, login signatures, transaction signatures or structured-data requests. Identify the request type first, then review the site, account, network, amount, contract and visible fields against your intended action. For Signature Requests, apply this principle to the specific fields and sequence described on this page.
A practical verification method
When applying signature requests in a real task, confirm the active account and network first, then inspect the permission or transaction fields requested by the interface. Familiar-looking screens are not a reason to skip verification.
Review token approval scope
A token approval gives a contract permission to use assets within a stated scope. Review the spender, allowance, network and whether an unlimited approval is truly necessary. Consider revoking permissions that are no longer needed. For Signature Requests, apply this principle to the specific fields and sequence described on this page.
Set boundaries for contract interaction
Smart contracts execute deployed code and can depend on external systems or market conditions. A wallet can display and submit requests, but it cannot determine whether a contract is safe or guarantee that an on-chain action can be reversed. For Signature Requests, apply this principle to the specific fields and sequence described on this page.
Keep your seed phrase and private key under your own control. imtoken support will not ask for them or for verification codes. Review the address, network, request details and permission scope before transferring, signing or approving. On-chain transactions are usually not reversible by a wallet provider. For Signature Requests, apply this principle to the specific fields and sequence described on this page.
Clean up connections and permissions
After using a DApp, disconnect sessions you no longer need and review historical approvals separately. Disconnecting a site does not necessarily revoke token permissions, so connection management and approval management are different tasks. For Signature Requests, apply this principle to the specific fields and sequence described on this page.
Applying Signature Requests in a real workflow
The value of understanding message signatures, transaction signatures, and typed data is not memorizing isolated terminology. It is building a repeatable decision process for each action. With Signature Requests, the visible button is only the start of an action; the actual outcome depends on the selected account, the active network, the destination address or contract, the permissions being requested, and the state eventually recorded on-chain. Define the outcome you expect before you approve the request shown on screen.
A useful review can be divided into four layers: message signatures used for authentication, transaction signatures authorizing state changes, reading typed-data fields, and avoiding blind confirmation of unclear requests. First confirm who or what the request is for. Next verify the network context. Then read the amount, fee, permission scope, or function parameters. Finally, after submission, compare the wallet record with a transaction hash or the appropriate block explorer. If any layer conflicts with what you intended to do, stop and re-check the source rather than trying a sequence of different confirmations.
A review habit worth keeping
For Signature Requests, proceed only when you can explain the important fields in your own words. An unfamiliar contract, unexpectedly broad approval, unexplained network switch, opaque signature, or any page asking for secret recovery material deserves additional scrutiny. A seed phrase or private key should remain under the user's control and should never be sent to another person. A DApp connection, message signature, token approval, and on-chain transaction are separate actions with separate consequences.
- State the intended network, destination, and expected result before starting.
- Before confirming, review the address, network, amount, fee, and permission scope that apply.
- After submission, keep the public transaction hash or equivalent reference and verify it on the matching network.
- When the task is complete, review connections and on-chain approvals that are no longer needed.
If a field in Signature Requests is not clear, learn what it represents before increasing value or permission scope. On-chain transactions generally cannot be reversed unilaterally by a wallet, and third-party DApps, bridges, and smart contracts introduce risks beyond the wallet interface. A deliberate sequence—understand, verify, then confirm—is more reliable than optimizing for speed.
