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.

Networks define where transactions happen

The first step in any on-chain action is confirming the network. The selected network determines where the transaction is broadcast, how fees are calculated, which explorer can verify status, and what confirmation rules apply. Similar address formats are not proof that assets are on the same network. For networks define where transactions happen, separate the object you are acting on, the active network, the expected outcome, and the evidence you can independently verify. Do not rely on interface wording alone; use addresses, transaction hashes, explorers, and contract details where appropriate. For this topic, a useful sequence is: understand the concept, check before acting, submit only when the details are clear, verify on-chain status, and review any permissions that remain afterward.

Before proceeding, confirm the network, the address or contract, the amount or permission scope, and the expected result. Keep sensitive recovery information offline and never send a seed phrase, private key, or verification code to another person.

Same address does not mean same asset

The selected network determines where the transaction is broadcast, how fees are calculated, which explorer can verify status, and what confirmation rules apply.

Gas and block space

The first step in any on-chain action is confirming the network. The selected network determines where the transaction is broadcast, how fees are calculated, which explorer can verify status, and what confirmation rules apply. Similar address formats are not proof that assets are on the same network. Gas prices can change with congestion, transaction complexity, and protocol conditions. A pending transaction is not the same as a final transaction, so verify the hash and confirmation state on the correct network before relying on the result. For this topic, a useful sequence is: understand the concept, check before acting, submit only when the details are clear, verify on-chain status, and review any permissions that remain afterward.

Confirmations and finality

The first step in any on-chain action is confirming the network. The selected network determines where the transaction is broadcast, how fees are calculated, which explorer can verify status, and what confirmation rules apply. Similar address formats are not proof that assets are on the same network. For confirmations and finality, separate the object you are acting on, the active network, the expected outcome, and the evidence you can independently verify. Do not rely on interface wording alone; use addresses, transaction hashes, explorers, and contract details where appropriate. For this topic, a useful sequence is: understand the concept, check before acting, submit only when the details are clear, verify on-chain status, and review any permissions that remain afterward.

On-chain transactions generally cannot be unilaterally reversed by a wallet. Third-party DApps, smart contracts, bridges, and staking services may involve technical or operational risk. Digital-asset prices can also fluctuate. Review each action based on your own circumstances.
