FAQ
Clear answers to common wallet, network, Web3 and security questions.
What is the difference between a wallet address and a private key?
A wallet address can be shared for receiving assets. A private key controls assets and must remain under the user’s custody; it should never be sent to anyone.
Can official staff recover a lost seed phrase?
No. A seed phrase is used to restore wallet control and should be backed up offline. Official staff should never ask for it and cannot recover a user’s private key.
Why must I verify the network before sending assets?
The same asset may exist on multiple networks. A wrong network can prevent the transfer from arriving as intended, and on-chain transactions generally cannot be unilaterally reversed by a wallet.
What is gas?
Gas is the network fee mechanism used to execute transactions or contract calls. Cost depends on network demand, transaction complexity and protocol rules.
What is a transaction hash used for?
A transaction hash is a unique identifier that can be used in a block explorer to check broadcast, inclusion, confirmation, failure or other on-chain status.
What should I do if a transaction is pending?
Verify the network, transaction hash and block-explorer status before taking another action. The cause may be congestion, fee settings or another network condition.
Does connecting to a DApp mean I already approved something?
Not necessarily. A connection usually creates an interaction channel. Signatures, transactions and token approvals are separate requests that should each be reviewed independently.
Is a message signature the same as a transaction signature?
No. A message signature often does not transfer assets directly but may express login or authorization intent. A transaction signature can submit a state-changing transaction.
Why should I inspect a token approval amount?
The allowance determines how much a contract may use on behalf of the account. Verify the spender, contract address and amount, and consider revoking approvals that are no longer needed.
What is an EVM network?
An EVM network uses an execution model compatible with the Ethereum Virtual Machine. Networks may share similar address formats while keeping assets, gas rules and contract state separate.
How does Layer 2 relate to mainnet?
Layer 2 systems process some activity outside the base layer and connect results or data back to mainnet through specific mechanisms. Cross-layer transfers may involve bridges and waiting periods.
How can I recognize a suspicious DApp request?
Verify the domain, request source, contract address, signature content and permission scope. Stop if a site asks for a seed phrase, promotes an unexplained airdrop or requests remote-control access.
Is public Wi-Fi suitable for wallet operations?
Public networks can increase exposure to phishing, interception or device risk. Sensitive actions are better performed on trusted devices and networks with current system and browser updates.
Does Ethereum staking guarantee returns?
No. Rewards can change with protocol conditions and validator performance. Waiting periods, penalties, contract risk and asset-price volatility also matter.
What penalties can a PoS validator face?
Depending on network rules, downtime, protocol violations or other validator behavior can reduce rewards or trigger penalties.
What should I do after finding an unexpected approval?
Stop further interaction, disconnect unnecessary DApp sessions, inspect the spender and allowance from a trusted entry point, and consider revoking the approval after understanding the effect.
What are the three most important checks before a transfer?
Address, network and amount. Also review gas, token contract and the transaction summary before signing.
