imtoken will never ask for your seed phrase, private key or verification code. Always review the address, network and request details before transferring, signing or approving.

Common questions

A digital wallet manages addresses and keys, reads on-chain assets, and builds or signs transactions. The asset record lives on the blockchain rather than simply inside an app interface.

No. Seed phrases and private keys should remain under your control, and official support should not request them.

A private key controls a specific account, while a seed phrase commonly restores a set of derived keys. Both are highly sensitive.

Assets can exist on different networks. The network determines where a transaction is executed, so sender and receiver must agree on the intended network.

Gas represents computation and storage used by on-chain execution. Actual fees vary with network conditions and transaction complexity.

It is the main reference used to look up transaction status, fees and contract calls in a block explorer.

A connection only opens an interaction channel. Every later signature, approval and transaction should still be reviewed independently.

No. A message signature may authorize login or another off-chain flow, while a transaction signature normally submits an on-chain state change.

It lets a contract spend a defined amount of a token. Review the spender, amount and need before approving.

Use a reliable approval-management method for the relevant network and verify the contract before revoking unnecessary permissions.

An EVM network uses an Ethereum-compatible smart-contract execution environment. Similar address formats do not merge balances across networks.

Layer 2 processes more activity outside mainnet and posts key data or proofs back to it, improving throughput or cost.

A confirmed blockchain transfer usually cannot be reversed by the wallet alone, so verify address, network and amount first.

Check domains, entry points and request details. Never enter a seed phrase or private key into an unknown page.

No. Rewards can change, validators can be penalized, exits can take time, smart contracts can fail and market prices can fluctuate.

A validator participates in block proposal and attestation according to protocol rules and may receive rewards or penalties.

Confirm the network, address and token contract. A display issue does not necessarily mean the on-chain balance is missing.

Public networks can increase interception and device-security risk. Sensitive operations are safer on a trusted device and network.
