Signature Requests

Protect the Most Important Security Boundary

When learning about Signature Requests, it helps to treat message signatures, transaction signatures, request contents and malicious signing as parts of one information chain. A balance or action button is only the interface layer; the outcome depends on the active network, the destination address or contract, the exact request being signed, and the record ultimately accepted on-chain. imtoken can present these details in a clearer way, but the final review still belongs to the user. Similar-looking addresses or familiar asset names are not enough to prove that the selected network is correct.

From a risk-management perspective, Signature Requests should not be treated as a one-time configuration. Network conditions, gas requirements, DApp requests and contract permissions can change, which means important details deserve a fresh review each time. A legitimate website or support channel should never ask you to send a seed phrase, private key or verification code. Connections and approvals that are no longer needed can also be reviewed and, where appropriate, revoked to reduce long-term exposure.

Recognize Common Risk Scenarios

In practice, message signatures often changes how you should interpret transaction signatures, while request contents affects whether the request can be processed as expected. When malicious signing is involved, review the counterparty, permission scope, amount and network again. Avoid making decisions from a logo, page title or screenshot alone. Independent checks through a block explorer, official network documentation and a transaction hash are more reliable. Once an on-chain transaction is confirmed, a wallet normally cannot reverse it unilaterally, so careful review before confirmation matters more than recovery afterward.

A useful way to learn Signature Requests is to break a real task into four stages: prepare, review, execute and verify. During preparation, confirm the target and network. During review, inspect message signatures and transaction signatures. During execution, watch how request contents changes. After completion, use malicious signing or an on-chain record to confirm the result. This approach prevents the wallet interface from becoming your only source of truth and makes it easier to distinguish congestion, fee issues, incorrect addresses, contract restrictions and third-party service problems.

Use a Two-stage Check Before Acting

From a risk-management perspective, Signature Requests should not be treated as a one-time configuration. Network conditions, gas requirements, DApp requests and contract permissions can change, which means important details deserve a fresh review each time. A legitimate website or support channel should never ask you to send a seed phrase, private key or verification code. Connections and approvals that are no longer needed can also be reviewed and, where appropriate, revoked to reduce long-term exposure.

For long-term use, favor minimum permissions and minimum exposure. Connect to DApps only when necessary, approve only what the current task requires, keep seed phrases and private keys away from easily synchronized or shared locations, and re-check the address, network and amount before sending assets. The purpose of Signature Requests is not to promise perfect security. It is to give you clearer information about what you are authorizing, what risks may remain and which on-chain evidence can be used to verify the outcome.
