Start with the Core Concepts
Layer 2 systems move some activity away from the base chain to improve capacity, while settlement and data models vary by design. The practical way to understand Layer 2 Basics is to place it inside a real user journey rather than memorize isolated terms. 理解 layer2 与主网关系、跨层、bridge 和到账确认 should be checked before an action, during confirmation and again after completion. Verify the entry point and network first, read addresses, permissions, fees and request details at confirmation, then use on-chain records to validate the outcome.
Many mistakes around Layer 2 Basics begin with information that looks familiar: similar network names, address formats, token symbols or interface layouts. Prefer details that can be independently checked, such as the full domain, network name, contract address, transaction hash and a matching block-explorer record, instead of relying on icons, nicknames or screenshots. For Layer 2 Basics, break the task into small points that can be verified rather than continuing while the network, address, permission or transaction state is still unclear.
Pre-action check
Confirm that the page and network match the task, then review public addresses, assets, fees or permission details. A familiar interface is not a reason to skip the request details of a third-party DApp or smart contract.
How the Mechanism Works
Depositing to or withdrawing from a Layer 2 can involve bridges, waiting periods and additional confirmations, so it should not be treated as an ordinary same-chain transfer.

imtoken treats user review as the final decision point for Layer 2 Basics. This site never asks for seed phrases, private keys or verification codes, and it does not promise that confirmed on-chain transactions can be reversed by the wallet. DApps, smart contracts, networks and third-party services each introduce their own risk boundaries.

Practical Decision-Making
Verify the exact network, route and supported asset before moving funds across layers, and expect timing to differ from a base-chain transaction. imtoken treats user review as the final decision point for Layer 2 Basics. This site never asks for seed phrases, private keys or verification codes, and it does not promise that confirmed on-chain transactions can be reversed by the wallet. DApps, smart contracts, networks and third-party services each introduce their own risk boundaries.
If the result differs from what you expected, preserve non-secret details such as the transaction hash, network and public address, then begin troubleshooting from on-chain state. Never send recovery information to someone claiming to provide support, and do not sign an unfamiliar request simply because it is presented as a fix. For Layer 2 Basics, break the task into small points that can be verified rather than continuing while the network, address, permission or transaction state is still unclear.
Post-action check
Confirm that the page and network match the task, then review public addresses, assets, fees or permission details. A familiar interface is not a reason to skip the request details of a third-party DApp or smart contract.

You are responsible for keeping seed phrases and private keys private. imtoken personnel will never ask for them. Verify address, network and amount before sending; confirmed on-chain transactions generally cannot be reversed by the wallet.
