Build the right mental model
Layer 2 systems scale activity by moving some execution or data work away from the base chain, but their security relationships and data-publishing models vary by design. When working with Layer 2 Basics, separate what the interface displays from facts that can be verified on-chain. A wallet can organize information and prepare requests, but the network, address, contract, and final transaction state still need independent context. If a critical field cannot be explained, stop before confirming and verify it again instead of responding to urgency from a page, an unknown contact, or short-term market movement.
Moving assets between a base chain and Layer 2 can involve a bridge, waiting periods, fees, and different finality conditions. In a real workflow, Layer 2 Basics should not be reduced to a single click or one status message. Review the network, account, requested action, amount, and permission scope as separate checkpoints so inconsistencies become visible earlier. If a critical field cannot be explained, stop before confirming and verify it again instead of responding to urgency from a page, an unknown contact, or short-term market movement.
Key fields
- Confirm that the network, address, or contract involved in Layer 2 Basics matches the intended context
- Use public information for verification and never submit a seed phrase, private key, or verification code
- Treat signatures, approvals, transfers, and contract calls as separate decisions rather than permanent trust

The same token may have different contracts or representations on the base chain and a Layer 2, so confirm which layer currently holds the asset before sending. Risk often hides inside familiar-looking details. Similar names, addresses, domains, and repeated confirmation dialogs can make a request feel routine even when the underlying target or authority is different. If a critical field cannot be explained, stop before confirming and verify it again instead of responding to urgency from a page, an unknown contact, or short-term market movement.
Order of operations

Layer 2 systems scale activity by moving some execution or data work away from the base chain, but their security relationships and data-publishing models vary by design. After a Layer 2 Basics action, review the final state and retain non-secret reference information such as the transaction hash, network name, or contract address when relevant so later verification is possible. If a critical field cannot be explained, stop before confirming and verify it again instead of responding to urgency from a page, an unknown contact, or short-term market movement.
Risk signals
- Confirm that the network, address, or contract involved in Layer 2 Basics matches the intended context
- Use public information for verification and never submit a seed phrase, private key, or verification code
- Treat signatures, approvals, transfers, and contract calls as separate decisions rather than permanent trust
