Layer 2 Basics

Read the network before reading the balance

Understand Layer 2, mainnet relationships, bridges, transfers, and confirmations. A blockchain network defines where balances, blocks, fees, transaction status, and contract state exist. Similar address formats do not make networks interchangeable, and identical asset names can refer to unrelated contracts.

For “Layer 2 Basics”, start with three questions: which network is active, which network the asset belongs to, and whether the destination supports that same network. Do not continue based only on an address shape or token name.

Understand the path from broadcast to confirmation

A submitted transaction is propagated to the network, validated, and eventually ordered or included according to the protocol. “Sent” is not the same as included in a block, and some applications wait for additional confirmations after inclusion.

Transaction hashes, block height, status, and confirmation count provide a better basis for judgment than repeated clicks. If a transaction fails, inspect the failure and fee details before creating another transaction with the same purpose.

Separate gas, contracts, and bridging layers

Networks have different fee rules. A simple transfer and a contract call consume different execution resources, while congestion can change the effective cost. EVM, Layer 2, bridges, and token contracts can all appear in one workflow but represent different technical layers.

For “Layer 2 Basics”, verify the network, contract, fee, and cross-network path independently. In bridge or cross-layer flows, success on the source network does not necessarily mean the destination state is already available.

• Check the active network
• Verify address, contract, or approval target
• Review amount, fees, and request details
• Keep the transaction hash when relevant
• Reject requests you cannot explain

Public state does not make every application trustworthy

Public blockchains provide inspectable transaction history, but tokens, contracts, bridges, and DApps can be created by different parties. A healthy base network does not guarantee the safety of every third-party component.

Read-only explorer queries usually do not require a wallet connection and never require a seed phrase or private key. Verify domains when opening explorers, bridges, or documentation, especially when arriving from ads or unsolicited links.
