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.

Knowledge Guide

Layer 2

Understanding Layer 2 is less about memorizing terminology and more about knowing how the concepts affect real on-chain actions. imtoken presents the topic from underlying mechanics to practical checks so users can reason about networks, addresses, fees and confirmations before they transfer assets, connect to applications or inspect transaction status.

Understanding relationship to mainnet

Relationship to mainnet deserves its own verification step when working with Layer 2. Do not rely only on a familiar label or a default selection in the interface. Consider the active network, the destination or contract, the current on-chain state and the result you actually expect. For transfers, signatures or approvals, review the address, network, amount, gas information, contract or permission scope before confirmation. Afterward, use the transaction record or an appropriate block explorer to verify what happened. On-chain transactions generally cannot be reversed unilaterally by a wallet, so prevention matters more than recovery.

In a real Layer 2 workflow, relationship to mainnet should not be treated as an isolated field. Read it together with the active network, the source of the asset, the destination, the party initiating the request and the expected on-chain result. If any part differs from what you intended, stop before confirming and verify the source and parameters instead of trying repeated approvals.

Keep verifiable on-chain references such as transaction hashes, contract addresses and network names when they are relevant. A web page that asks for a seed phrase, private key or verification code should be treated as a serious warning sign. Legitimate support should not request those secrets, and a wallet cannot reset or recover a private key on behalf of the user.

How cross-layer assets affects the workflow

Cross-layer assets deserves its own verification step when working with Layer 2. Do not rely only on a familiar label or a default selection in the interface. Consider the active network, the destination or contract, the current on-chain state and the result you actually expect. For transfers, signatures or approvals, review the address, network, amount, gas information, contract or permission scope before confirmation.

  • Confirm that the action matches your goal for cross-layer assets
  • Verify the address, network and amount before a transfer
  • Review the target and permission scope before signing or approving
  • Check transaction history and on-chain status after completion

Working with bridges

Bridges deserves its own verification step when working with Layer 2. Do not rely only on a familiar label or a default selection in the interface. Consider the active network, the destination or contract, the current on-chain state and the result you actually expect. For transfers, signatures or approvals, review the address, network, amount, gas information, contract or permission scope before confirmation.

Settlement and confirmations and risk checks

Settlement and confirmations deserves its own verification step when working with Layer 2. Do not rely only on a familiar label or a default selection in the interface.
