Identify the network first
Each blockchain has its own nodes, consensus process, fee asset and block-space conditions. Confirming the network before an action is the first defense against using the wrong environment, contract or fee model.
Addresses, fees and network parameters
Address formats can look similar across networks even though network state and parameters differ. Gas is normally paid with the network’s designated native asset, so holding a token does not necessarily mean you can submit a transaction.
A practical verification method
When applying layer 2 in a real task, confirm the active account and network first, then inspect the permission or transaction fields requested by the interface. Familiar-looking screens are not a reason to skip verification.
What blocks and confirmations mean
Once included in a block, a transaction begins accumulating confirmations as new blocks are produced. Networks differ in block timing and finality, so there is no universal confirmation duration that applies everywhere.
Using explorers for verification
A block explorer lets you look up public chain data by address, transaction hash or contract. Use an explorer for the correct network and review status, block height, sender, recipient, value and contract interaction details.
Keep your seed phrase and private key under your own control. imtoken support will not ask for them or for verification codes. Review the address, network, request details and permission scope before transferring, signing or approving. On-chain transactions are usually not reversible by a wallet provider.
Extra checks for cross-network actions
Cross-chain and cross-layer actions introduce bridges, message-passing systems or waiting periods. Verify the source and destination networks, supported asset, fees and settlement conditions, and account for third-party or smart-contract risk.
