Layer 2

Understand Layer 2, its relationship with mainnet, bridging and settlement confirmation.

Safety principle

Never share your seed phrase, private key or verification code. Review the address, network and request details before you sign, approve or transfer.

Why Layer 2 exists

How to evaluate it

Why Layer 2 exists is a distinct part of understanding Layer 2. Separate interface labels from on-chain facts: an address identifies an account, the selected network determines where the asset and transaction exist, and a signature or approval can change permissions or trigger execution. The goal is not to memorize button positions. A safer habit is to identify the request, the network, the permission being granted and the result you expect before you confirm anything.

Separate interface labels from on-chain facts: an address identifies an account, the selected network determines where the asset and transaction exist, and a signature or approval can change permissions or trigger execution. Fees, confirmation speed and supported features vary across networks. A wallet interface is only one view of the activity; the corresponding blockchain record remains the stronger reference for transaction status.

Use a least-privilege mindset. Never share a seed phrase, private key or verification code, and do not lower your review standard because a request claims to be support, an airdrop, an upgrade or an urgent notice.

Bridges and cross-layer waiting

How to evaluate it

Bridges and cross-layer waiting is a distinct part of understanding Layer 2. Separate interface labels from on-chain facts: an address identifies an account, the selected network determines where the asset and transaction exist, and a signature or approval can change permissions or trigger execution. Use a least-privilege mindset.

Bridges and cross-layer waiting is a distinct part of understanding Layer 2. Separate interface labels from on-chain facts: an address identifies an account, the selected network determines where the asset and transaction exist, and a signature or approval can change permissions or trigger execution. A repeatable sequence helps: verify the source, check the address and network, review the amount or permission, then keep the transaction hash and verify confirmation on-chain. Stop when details conflict.

Settlement and network selection

Settlement and network selection is a distinct part of understanding Layer 2.
