How Layer 2 relates to a base layer
Layer 2 does not treat every activity as a direct mainnet transaction; it uses a specific processing model and then relates required data or results back to the base layer. A useful way to understand this is to connect the concept with its operating conditions and the result recorded on-chain. imtoken focuses on making network, transaction and permission details understandable before users confirm an action. The wallet interface can prepare and display an action, but the selected network ultimately records transaction state, so a clickable button is not proof that every parameter is correct.
For practical use, define the intended outcome first and then review the items related to how layer 2 relates to a base layer one by one. Confirm the network and account context, check the address, asset or requesting contract, and only then review fees, permissions and confirmation details. Separating these checks makes it easier to identify whether an unexpected result comes from the network, transaction parameters, a contract or local display state.
A helpful learning model for how layer 2 relates to a base layer is to divide an action into preparation, submission, network confirmation and follow-up review. Layer 2 does not treat every activity as a direct mainnet transaction; it uses a specific processing model and then relates required data or results back to the base layer. Preparation checks whether conditions match, submission checks the exact request, confirmation verifies what the network recorded, and follow-up review covers transaction history and any permissions that remain active.
- Confirm the network, account or requester related to how layer 2 relates to a base layer
- Verify the address, network and amount before a transfer; consider a small test when appropriate
- Read signature and approval details instead of treating later requests as automatically trusted
- Keep the transaction hash or other information needed to verify on-chain status
What to do when the result differs from expectations
If the interface, network state or outcome does not match what you expected, avoid repeatedly submitting the same action. Confirm the active network and account, then use the transaction hash, a suitable block explorer or contract information to establish what has already happened. For how layer 2 relates to a base layer, distinguishing a local display issue from a transaction already recorded on-chain is an important first step.
Why moving across layers needs a dedicated process
Depositing to or withdrawing from a Layer 2 commonly uses a bridge or protocol flow; sending to the same-looking address does not automatically move assets across layers. A useful way to understand this is to connect the concept with its operating conditions and the result recorded on-chain. imtoken focuses on making network, transaction and permission details understandable before users confirm an action.

Why confirmation can happen in stages
A cross-layer action can include source-chain confirmation, bridge processing and destination-chain arrival, and waiting or finality conditions vary by mechanism.

What to verify when selecting a Layer 2 path
Check the network name, bridge source, destination chain, asset contract, fee and expected flow, and avoid cross-layer actions through unfamiliar links.
