FAQ
imtoken FAQ covering wallets, seed phrases, private keys, networks, transfers, gas, transaction hashes, DApps, approvals, EVM, Layer 2, Ethereum and validators.
Use a trusted download entry point and decide how you will keep recovery information offline. Complete the seed phrase backup before receiving or sending meaningful assets.
A seed phrase commonly restores a set of wallet keys, while a private key directly controls signing for a specific account. Neither should be sent to anyone or submitted to “support” for verification.
Many EVM networks share the same address format, but chain ID, gas asset, contracts and network state remain separate. Similar addresses do not make the networks interchangeable.
Check the destination address, network, asset, amount and estimated gas. For an exchange or service, also confirm the deposit network it explicitly supports.
Gas is the network fee for executing and recording an on-chain action. It is generally determined by network rules and demand rather than being a fixed wallet charge.
A transaction hash identifies an on-chain transaction and can be used in a block explorer to review status, block height, confirmations, addresses and fees.
Connection usually opens an interaction channel, but later signatures, transactions or approvals may change on-chain state. Review each request separately.
No. A message signature can prove account control or authorize data, while a transaction signature submits an on-chain action. Both deserve source and content review.
The allowance determines how much a contract may use. Large or long-lived approvals widen exposure and may be worth revoking when they are no longer needed.
Use chain ID, native gas asset, RPC information or official network documentation instead of relying only on the address format.
Layer 2 systems extend transaction processing while relying on a base chain in different ways. Cross-layer asset moves normally use a bridge or messaging path and may have separate confirmation or exit timing.
Do not rely on a provider to reset or recover a leaked private key. If exposure is suspected, consider moving controllable assets to a new secure wallet and reviewing existing approvals.
Screenshots may be exposed through cloud sync, photo backups, malware or sharing features. Offline storage usually reduces that exposure.
Do not provide it. imtoken will not ask for your seed phrase, private key or verification code. End the conversation and re-check through a known trusted entry point.
No. Rewards can change with protocol conditions, participation and validator performance, and there are waiting, penalty, technical, contract and market risks.
Validators must follow consensus rules and operate correctly. Downtime, incorrect behavior or serious protocol violations can lead to different penalties.
A broadcast and confirmed blockchain transaction generally cannot be unilaterally reversed by a wallet. Address, network and amount checks before signing are essential.
