Layer 2

Establish the right context: base-layer relationship

base-layer relationship is easy to misunderstand when context is missing. The account, cross-layer transfers, and the intended action should agree before a familiar interface is treated as meaningful evidence.

If an interface mixes several layers of information, check base-layer relationship, cross-layer transfers, and bridges separately. Names, icons, and familiar layouts are presentation details, not substitutes for the actual network, address, contract, or on-chain state. When the evidence conflicts, fewer new actions usually make troubleshooting easier.

Verification continues after submission. Keep public evidence related to base-layer relationship and use cross-layer transfers to review status when necessary. On-chain transactions generally cannot be reversed by a wallet provider alone, and third-party DApps or contracts can carry their own risks, so blind resubmission is a poor troubleshooting method.

Understand how it works in practice: cross-layer transfers

How cross-layer transfers, bridges, and arrival confirmation relate in practice

Within Layer 2, cross-layer transfers is not an isolated term; it affects bridges and the on-chain result a user eventually sees.

For Layer 2, a repeatable verification habit is more durable than memorizing where a button appears. Check cross-layer transfers, then bridges, and finally arrival confirmation. Interfaces can change and network conditions can move, while the reasoning behind those checks remains useful.

The purpose of learning Layer 2 is to understand the action rather than mechanically complete it. Whenever cross-layer transfers, bridges, or the expected result cannot be explained, preserve the option to decline, exit, or verify again later.

• Confirm the real object behind cross-layer transfers
• Check the network or permission scope for bridges
• Use arrival confirmation or another public record to verify the result
• Never share a seed phrase, private key or verification code

Review the action step by step: bridges

When using Layer 2, first identify whether the current object is an account, asset, network, transaction or permission. Then relate bridges to arrival confirmation instead of reading either label alone.

A useful review order is source, object, request, and result. The source establishes where the action came from, bridges identifies the object, and arrival confirmation clarifies the scope. After submission, keep a transaction hash or other public record so that changing status can be checked again without relying on one interface message.

Over time, revisit bridges and arrival confirmation, remove connections or permissions that are no longer needed, and keep the device and browser environment trustworthy. Security is not an absolute promise; it is a process of reducing secret exposure, mistaken approvals, and avoidable uncertainty.

Recognize common mistakes and risks: arrival confirmation

How arrival confirmation, exit waiting, and base-layer relationship relate in practice

When a request involves arrival confirmation, slow the decision down enough to identify what it changes, which network it relies on, and whether exit waiting can be independently verified.

Do not treat “already connected,” “used before,” or “looks familiar” as sufficient evidence. Review arrival confirmation for the actual object, exit waiting for the transaction or permission boundary, and base-layer relationship for the resulting state. If one step remains unclear, declining is a valid outcome.

Keep the security boundary explicit: the user controls the seed phrase and private keys, and imtoken will never ask for them. If a third party links arrival confirmation to a request for recovery secrets or verification codes, stop. When exit waiting is involved, also verify the address, network, amount or permission scope.

• Confirm the real object behind arrival confirmation
• Check the network or permission scope for exit waiting
• Use base-layer relationship or another public record to verify the result
• Never share a seed phrase, private key or verification code

Build a repeatable verification habit: exit waiting

A practical way to approach exit waiting is to place it inside a real task and start with base-layer relationship.

The same term can behave differently across networks or DApps, so exit waiting should always be interpreted in context. base-layer relationship provides a second verification angle, while cross-layer transfers helps confirm what actually happened afterward. Network-specific rules should be checked against trustworthy information for that network.

If a result differs from expectations, record exit waiting, base-layer relationship, and other non-secret evidence, then reconstruct the sequence of actions. Never send recovery secrets to someone offering to “restore” or “verify” an account, and avoid untrusted remote-control software.
