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.

Core concepts

Put each term back into its on-chain context: networks, accounts, transactions and contracts have different responsibilities. In the context of addresses and public keys, it also helps to connect gas and nonce with contracts and approvals rather than treating them as isolated features. When checking state, prefer verifiable evidence such as network, address, contract and transaction hash. Keep the actual request details visible, and stop if the network, contract or permission cannot be explained clearly.

A useful review habit is to compare addresses and public keys with the active network state and the exact request shown by the wallet. Third-party DApps and smart contracts may introduce their own risk, and confirmed on-chain transactions usually cannot be reversed by the wallet alone.

Practical workflow

When checking state, prefer verifiable evidence such as network, address, contract and transaction hash. In the context of gas and nonce, it also helps to connect contracts and approvals with bridges and validators rather than treating them as isolated features. Networks can share similar address formats while keeping independent balances, gas assets, block histories and confirmation rules. Keep the actual request details visible, and stop if the network, contract or permission cannot be explained clearly.

gas and nonce

contracts and approvals

Networks can share similar address formats while keeping independent balances, gas assets, block histories and confirmation rules.

bridges and validators

When third-party nodes, bridges or contracts are involved, evaluate their technical risk separately from the wallet interface.

Review checklist

  • Put each term back into its on-chain context: networks, accounts, transactions and contracts have different responsibilities.
  • When checking state, prefer verifiable evidence such as network, address, contract and transaction hash.
  • Networks can share similar address formats while keeping independent balances, gas assets, block histories and confirmation rules.
  • When third-party nodes, bridges or contracts are involved, evaluate their technical risk separately from the wallet interface.

Key risks

  • Never share a seed phrase, private key or verification code.
  • Third-party DApps, networks and contracts can fail or behave maliciously.
  • Staking and digital assets do not offer guaranteed returns or protection from price volatility.
