Layer 2

Build the right model

Layer 2 makes more sense when mainnet relationship, cross-layer movement, bridges, arrival confirmation, network selection are considered as parts of one on-chain workflow. The goal is not to memorize more terminology, but to make each action explainable, verifiable and reviewable.

During real use, confirm the active network and account first, then verify the object, scope and expected outcome related to mainnet relationship. Any action that changes assets, permissions or account state deserves a full review before confirmation.

Understand the on-chain relationship

During real use, confirm the active network and account first, then verify the object, scope and expected outcome related to mainnet relationship. Any action that changes assets, permissions or account state deserves a full review before confirmation.

For cross-layer movement, prefer information that can be independently checked: the wallet transaction summary, the relevant network explorer, an explicit contract address or an official product page. Breaking an action into separate checks reduces mistakes caused by familiar-looking pages, similar links or urgent prompts.

What to verify in practice

For cross-layer movement, prefer information that can be independently checked: the wallet transaction summary, the relevant network explorer, an explicit contract address or an official product page. Breaking an action into separate checks reduces mistakes caused by familiar-looking pages, similar links or urgent prompts.

When bridges is involved, separate display data from on-chain facts. Names, icons and fiat estimates may come from external data sources, while balances, transaction state and approvals should be verified on the selected network.

Common mistakes and risks

When bridges is involved, separate display data from on-chain facts. Names, icons and fiat estimates may come from external data sources, while balances, transaction state and approvals should be verified on the selected network.

For arrival confirmation, retain the transaction hash or other useful reference when appropriate. On-chain transactions generally cannot be reversed unilaterally by a wallet, which makes pre-broadcast checks of the address, network, amount and permissions especially important.

Build a repeatable decision process

For arrival confirmation, retain the transaction hash or other useful reference when appropriate. On-chain transactions generally cannot be reversed unilaterally by a wallet, which makes pre-broadcast checks of the address, network, amount and permissions especially important.

Finally, consider network selection. Third-party DApps, smart contracts and network services can introduce technical, operational and market risk. Unclear signatures, unnecessarily broad approvals, or any page asking for a seed phrase or private key are reasons to stop and re-check the request.
