01
Understand the role of Layer 2
Within imtoken guidance on Layer 2 Networks & Cross-layer Transfers, Layer 2 should not be treated as an isolated term. Its practical meaning depends on the selected network, the account address, the origin of the request and the final on-chain record. Place the concept in a real wallet workflow rather than memorising a definition. Its meaning becomes clearer when you relate it to the network, address, request details and the final on-chain result. For everyday use, the important skill is knowing when the information is complete enough to proceed, when a mismatch should stop the action, and which data can be checked publicly without exposing recovery secrets. Using that framework for Layer 2 helps distinguish a temporary interface status from a confirmed blockchain result and reduces mistakes caused by choosing the wrong network or trusting an unexpected request.
Work backward from the expected result
Layer 2 Networks & Cross-layer Transfers often combines several conditions at once. With Layer 2, start by confirming the active account and intended network, then review the displayed counterparty, amount, fee, data or permission scope as relevant. If the request differs from what you intended, do not confirm it simply because the site looks familiar. If a transaction has already been broadcast, use its transaction hash and explorer data to understand progress instead of guessing from a loading screen. The same reasoning applies to base-layer relationship and cross-layer transfers: every step should be explainable, independently reviewable and free from promises that cannot be verified on-chain.
- Confirm that Layer 2 matches the intended network context
- Review the account, contract or state related to base-layer relationship
- Keep public identifiers such as transaction hashes for troubleshooting
02
How base-layer relationship affects real actions
Within imtoken guidance on Layer 2 Networks & Cross-layer Transfers, base-layer relationship should not be treated as an isolated term. Its practical meaning depends on the selected network, the account address, the origin of the request and the final on-chain record. During an actual action, compare the interface with on-chain context. Pay particular attention to the selected network, address format, transaction state and the contract or account requesting permission. For everyday use, the important skill is knowing when the information is complete enough to proceed, when a mismatch should stop the action, and which data can be checked publicly without exposing recovery secrets. Using that framework for base-layer relationship helps distinguish a temporary interface status from a confirmed blockchain result and reduces mistakes caused by choosing the wrong network or trusting an unexpected request.

- Review the account, contract or state related to cross-layer transfers
- Keep public identifiers such as transaction hashes for troubleshooting
03
What to review around cross-layer transfers
Within imtoken guidance on Layer 2 Networks & Cross-layer Transfers, cross-layer transfers should not be treated as an isolated term. Its practical meaning depends on the selected network, the account address, the origin of the request and the final on-chain record. When a status is unclear, avoid repeatedly submitting the same action. Check the transaction hash, block explorer data and the confirmation state on the intended network before deciding what to do next. For everyday use, the important skill is knowing when the information is complete enough to proceed, when a mismatch should stop the action, and which data can be checked publicly without exposing recovery secrets. Using that framework for cross-layer transfers helps distinguish a temporary interface status from a confirmed blockchain result and reduces mistakes caused by choosing the wrong network or trusting an unexpected request.

The same reasoning applies to bridges and arrival confirmation: every step should be explainable, independently reviewable and free from promises that cannot be verified on-chain.
- Confirm that cross-layer transfers matches the intended network context
- Review the account, contract or state related to bridges
- Keep public identifiers such as transaction hashes for troubleshooting
04
Common mistakes involving bridges
Within imtoken guidance on Layer 2 Networks & Cross-layer Transfers, bridges should not be treated as an isolated term. Its practical meaning depends on the selected network, the account address, the origin of the request and the final on-chain record. Treat every signature, approval and transfer as a separate decision. A service that was previously connected should not automatically be trusted for a new request with different permissions or transaction data. For everyday use, the important skill is knowing when the information is complete enough to proceed, when a mismatch should stop the action, and which data can be checked publicly without exposing recovery secrets. Using that framework for bridges helps distinguish a temporary interface status from a confirmed blockchain result and reduces mistakes caused by choosing the wrong network or trusting an unexpected request.

The same reasoning applies to arrival confirmation and network selection: every step should be explainable, independently reviewable and free from promises that cannot be verified on-chain.
- Confirm that bridges matches the intended network context
- Review the account, contract or state related to arrival confirmation
- Keep public identifiers such as transaction hashes for troubleshooting
05
How to interpret arrival confirmation states
Within imtoken guidance on Layer 2 Networks & Cross-layer Transfers, arrival confirmation should not be treated as an isolated term. Its practical meaning depends on the selected network, the account address, the origin of the request and the final on-chain record. For troubleshooting, retain information that can be shared safely, such as a transaction hash, network name and approximate time. Never provide a seed phrase, private key or verification code as diagnostic information. For everyday use, the important skill is knowing when the information is complete enough to proceed, when a mismatch should stop the action, and which data can be checked publicly without exposing recovery secrets. Using that framework for arrival confirmation helps distinguish a temporary interface status from a confirmed blockchain result and reduces mistakes caused by choosing the wrong network or trusting an unexpected request.

- Review the account, contract or state related to network selection
- Keep public identifiers such as transaction hashes for troubleshooting
06
Make network selection part of a routine
Within imtoken guidance on Layer 2 Networks & Cross-layer Transfers, network selection should not be treated as an isolated term. Its practical meaning depends on the selected network, the account address, the origin of the request and the final on-chain record. A consistent review order reduces mistakes: identify the counterparty or request first, confirm the network next, check the amount or permission scope, and only then sign or send. For everyday use, the important skill is knowing when the information is complete enough to proceed, when a mismatch should stop the action, and which data can be checked publicly without exposing recovery secrets. Using that framework for network selection helps distinguish a temporary interface status from a confirmed blockchain result and reduces mistakes caused by choosing the wrong network or trusting an unexpected request.

- Keep public identifiers such as transaction hashes for troubleshooting
A practical safety reminder
Keep seed phrases and private keys under your own control; legitimate support should not ask for them. Before a transfer, verify the address, network and amount. Before signing or approving, review the origin, contract and permission scope. On-chain transactions usually cannot be reversed by a wallet alone, and third-party DApps and smart contracts can carry risk.
