imtoken will never ask for your seed phrase, private key or verification code. Always review the address, network and request details before transferring, signing or approving.

01

Understand the role of DApps

In “Web3 Guides,” DApps is not an isolated idea. It works with Signatures and Contracts to determine what the user sees and where an action actually takes place. Once those boundaries are clear, interface prompts become easier to evaluate.

Web3 guidance should separate connection, signing, transactions and approvals. Knowing the consequence of each request gives users a basis for reviewing what a wallet confirmation screen shows. This section therefore focuses on reasoning through the relationship between DApps, Signatures and the resulting on-chain state rather than memorizing interface locations.

A practical review habit

  • Identify the active network and the object represented by DApps, not only its display name.
  • When Signatures is involved, confirm that both concepts share the intended network and permission context.
  • Keep public verification details such as a transaction hash when troubleshooting, but never expose recovery secrets.

02

How Signatures works with Approvals

Start with the goal of the action, then identify the network, address, contract or permission context represented by Signatures. Similar names, icons or page layouts do not prove that two environments are equivalent; network and on-chain identifiers provide stronger context.

03

Reviewing Approvals during an action

A repeatable review of Approvals can begin with the source and network, continue with the target and parameters, and end with the asset or permission change the action may create. Consistency is more useful than trying to confirm quickly.

Common assumptions to avoid

A common mistake around NFTs is treating display information as final on-chain truth, or assuming that a workflow that was safe once will be identical on another network, asset or DApp. Re-read the current request every time.

05

Make Contracts part of a routine

Making Contracts part of a routine means adding checkpoints before, during and after an operation: verify the conditions, read the request, then confirm the result through the transaction hash, network state or approval record.

Important security reminder

Seed phrases and private keys should remain under the user’s control, and official personnel will not request them or verification codes. Check the address, network and amount before a transfer; on-chain transactions generally cannot be unilaterally reversed by a wallet. Third-party DApps and smart contracts carry risk, so review the spender and permission scope and consider revoking unused approvals.

Before you continue

Use a repeatable review routine

  • Verify the active network and target address or contract
  • Read the amount, fee, signature or permission scope
  • Never send a seed phrase, private key or verification code to anyone
  • Verify the result through a transaction hash or approval record
  • If a request is unclear, stop and verify the source before continuing
