FAQ
Answers to common questions about wallets, networks, transfers, Web3 interactions, security, Ethereum, PoS and validators.
A digital wallet manages blockchain accounts, addresses and signing capability. Assets remain on the blockchain; control is established through the keys or credentials associated with an address.
A seed phrase is commonly used to derive or recover a set of wallet keys, while a private key directly authorizes signatures for a particular account. Both are highly sensitive.
No. imtoken personnel will not ask for a seed phrase, private key or verification code, and these should never be sent through websites, chats or email.
The same asset label can appear on different networks. Sending on the wrong network can prevent the asset from arriving in the expected context.
Gas measures the computation and block-space cost of an on-chain action. Payment method, units and fee dynamics depend on the network.
A transaction hash identifies a transaction and can be used in a block explorer to inspect status, confirmations, addresses and other on-chain data.
Network congestion, fee settings, node propagation and chain state can affect confirmation time. Check a reliable block explorer before submitting duplicates.
No. A connection usually establishes account visibility or a session. Signatures, transactions and token approvals should appear as separate requests.
No. A message signature may not transfer assets directly but can still authenticate or authorize something. A transaction signature generally authorizes an on-chain action.
A token approval allows a contract to use a specified token up to an allowance. Review the contract and amount, and consider revoking approvals you no longer need.
No. A larger allowance gives the approved contract a broader scope, so the potential impact can be larger if that permission becomes risky.
EVM-compatible networks share similar account and contract models, but gas tokens, chain IDs, block state and bridging mechanisms can differ.
Layer 2 systems move some execution or data processing to an expansion layer while maintaining a settlement or security relationship with mainnet. Mechanics vary by design.
A confirmed on-chain transaction generally cannot be reversed by a wallet acting alone. Replacement or acceleration of pending transactions depends on network rules and wallet support.
No. Rewards can change, exits can involve waiting periods, validators can face protocol penalties, and digital asset prices can fluctuate.
Validators participate in block proposal, attestations or other consensus duties defined by the protocol. Rewards and penalties depend on protocol conditions and validator performance.
Stop signing or approving, do not enter a seed phrase, private key or verification code, close the page and return through a trusted entry point to verify the domain and account state.
Use caution. Public environments can increase exposure to malware, remote access, session leakage or network interception. Important actions are better performed on trusted devices and networks.
