Questions and answers
What is the difference between a wallet address and a seed phrase?
A wallet address is normally used to receive assets and can be shared with a payer. A seed phrase is a sensitive recovery credential that can control wallet assets and must not be shared.
Can I send my private key to official support for verification?
No. imtoken staff will never ask for a private key, seed phrase or verification code.
What should I check before a transfer?
At minimum, verify the recipient address, selected network and amount, then review the displayed network fee or gas information.
What is a transaction hash used for?
A transaction hash is a unique identifier that can be used in a block explorer to inspect whether a transaction was broadcast, confirmed, failed or is still pending.
Why does gas change?
Gas costs depend on network rules and demand. Fee mechanisms differ by network, so review the current fee shown before submitting.
Does connecting to a DApp automatically let it move my assets?
Account connection and token approval are usually separate actions, but later signatures or approvals can grant permissions. Review each request independently.
What is a token approval?
A token approval allows a specified contract to operate tokens within a defined amount or rule set. Verify the spender, amount and contract address.
Why review old approvals?
Permissions can remain active after you stop using a DApp. Reviewing and revoking permissions you no longer need can reduce exposure.
Can EVM networks transfer directly to each other?
EVM networks may use similar address formats but remain separate networks. Cross-network asset movement normally requires a supported bridge or transfer mechanism.
How does Layer 2 relate to Ethereum mainnet?
Layer 2 systems expand transaction processing while relying on a relationship with the main chain for security or settlement. Bridging, finality and withdrawals vary by design.
What do block confirmations mean?
Confirmations indicate how many blocks have been built after the block containing a transaction. Different applications may require different confirmation counts.
What should I do with an unknown airdrop?
Do not follow unfamiliar links or approve unknown contracts merely because a token appears in your wallet. Verify the source, contract and network first.
Is it safe to use a wallet on public Wi-Fi?
Use extra caution on public networks, avoid high-risk operations when possible, and make sure the device, operating system and browser environment are trusted.
Does Ethereum staking guarantee returns?
No. Rewards can change, exits may involve waiting periods, validators can face protocol penalties, and digital asset prices are volatile.
Why can a PoS validator be penalized?
Validators can be penalized under protocol rules if they fail to perform required duties or engage in specific prohibited behavior.
What should I do with a suspicious signature request?
Reject or cancel it first, then verify the domain, request content and contract source. Do not confirm a request you do not understand.
Start with the core concepts
When learning about FAQ, focus on how 钱包, 网络 and 转账 relate rather than memorizing interface labels. Balances, addresses and statuses ultimately depend on rules and data on a specific network. Before acting, identify what you are handling, which network is involved and what outcome you expect.
In day-to-day use, 网络 often determines whether an action can complete as intended, while DApp can affect cost, confirmation time or permission scope. A useful routine is to review the source, verify parameters, confirm the request, perform the action and then verify the result independently.
转账 and 安全 may appear in the same workflow but they do not mean the same thing. When information is unclear, prefer verifiable on-chain data such as addresses, transaction hashes, block status and contract addresses. Similar-looking address formats do not guarantee that two networks are interchangeable.

Operations involving 安全 or Ethereum deserve extra attention because permissions, irreversibility and third-party behavior can introduce risk. imtoken staff will never ask for a seed phrase, private key or verification code. Connecting a wallet does not mean every later signature or approval request should be accepted.
Practical checklist
- Verify 钱包
- Verify 网络
- Verify 转账
- Verify DApp
- Verify 安全
Details that are easy to confuse
转账 and 安全 may appear in the same workflow but they do not mean the same thing. When information is unclear, prefer verifiable on-chain data such as addresses, transaction hashes, block status and contract addresses.

Connecting a wallet does not mean every later signature or approval request should be accepted.
If the result differs from what you expected, troubleshoot 钱包, DApp and Ethereum in sequence. Confirm the network and address first, inspect on-chain status next, and then check for pending, failed or mismatched permissions. Repeating an action without understanding the cause can create extra fees or duplicate approvals.

Consistent habits matter more than remembering where a button sits. Build a personal checklist around 钱包, 网络 and 转账, then use it before transfers, connections, signatures and approvals. Networks, DApps and third-party services change, so understanding principles is more durable than relying on one interface.
Security reminder
Never share a seed phrase, private key or verification code. Review addresses, networks and request details before signing, approving or transferring.
