Establish context from the core concepts: message signatures
Focus: message signatures, transaction signatures, and typed data
A signature proves account authorization over particular data or a transaction request, but different signatures have different consequences. Distinguish message signing, transaction signing, and contract-related requests before reviewing the domain, account, network, and payload.
When a third-party service is involved, separate message signatures, transaction signatures, and typed data as distinct concepts. They can appear on the same page or in one transaction, but they answer different questions; understanding those roles makes domains easier to interpret without mixing information layers.
The goal is not to memorize a vocabulary list but to establish context: is the subject an account, network, asset, transaction, or permission; which information comes from the local interface; and which result can be independently verified on-chain?
Understand how the concepts relate: typed data
Focus: typed data, domains, and nonces
When reviewing historical activity, place domains and nonces in a concrete task, with amounts providing additional state or result context. Concepts become easier to use when they are part of one continuous workflow rather than isolated definitions.
Do not judge target contracts and approval intent only by their names. Verify the network, address, contract, or transaction context that identifies the object before deciding which information matters next.
Blockchain implementations differ, so specific network parameters, confirmation rules, and contract behavior should be checked against trustworthy information for the relevant network or contract.
Apply the knowledge to real actions: nonces
Focus: nonces, amounts, and target contracts
In a multi-network environment, break a real task into four questions: source, object, request, and result. The source helps establish trust, the object identifies the account or network, the request explains the intended action, and the result should be checked against a record.
If message signatures or nonces appears during an action, understand its role in the current task instead of skipping review because the interface uses a familiar label. Third-party DApps and smart contracts can carry independent risk.
When a state cannot yet be explained, reducing new actions is usually easier to troubleshoot than repeated attempts. Keep public information such as the transaction hash, address, network, or contract and reconstruct changes in order.
Verify results with public information: target contracts
Focus: target contracts, approval intent, and message signatures
When re-checking an important action, look for independent evidence when verifying a result. Transactions can be checked through hashes and matching network records, assets through network and contract details, and permissions through the spender and scope.
amounts, target contracts, and approval intent provide different views of the situation. Reading them together reduces reliance on a single interface message, and none of them requires disclosing a seed phrase or private key.
On-chain transactions generally cannot be reversed by a wallet provider alone. Avoid blind resubmission while a result is unclear; determine whether the original request failed or remains pending before choosing the next step.
What to remember before continuing: message signatures
Focus: message signatures, transaction signatures, and typed data
Once the concept is placed in a real workflow, remember three points before moving on: establish network context, understand the request, and verify the result with a reliable record. The same reasoning can be applied to a new network, token, or DApp.
Stop if a page, support contact, or third-party service asks for a seed phrase, private key, or verification code. imtoken will never ask for those secrets.
Understanding Signature Requests cannot eliminate every risk, but it makes it clearer which details in message signatures, domains, and target contracts should be checked and preserves the option to decline or exit when the situation is uncertain.
Important check
Verify the address, network, and request details before any on-chain action. Third-party DApps and smart contracts can carry risk, and on-chain transactions generally cannot be reversed by a wallet provider alone.
Operation and security checklist
- Confirm the context for message signatures
- Cross-check transaction signatures and typed data
- Understand the request involving domains
- Keep a verifiable record related to amounts
- Review third-party DApp requests individually
- Never send a seed phrase, private key, or verification code to anyone
