Start with the core concept: gas
Place the concept back into a real on-chain workflow to see how networks, addresses, fees, confirmations and contracts relate to one another.
Gas prices execution resources, while confirmations describe how a transaction becomes more established as subsequent blocks are added.
Understanding gas is less about memorizing a definition and more about knowing where it appears in a real workflow, which details deserve attention, and what can go wrong when the wrong network or request is accepted. imtoken frames the topic around practical decisions: confirm the account and network first, read the request carefully, and only then decide whether to continue.
In a multi-chain environment, gas often appears together with addresses, gas, transaction status and contract information. Similar-looking addresses do not make different networks interchangeable, and assets with the same symbol may come from different contracts. Cross-check the network, contract address, recipient and transaction details instead of relying on a ticker or a visual label alone.
Before proceeding, be clear about what you are connecting, signing, approving or sending. A wallet can display the request it receives, but it cannot independently guarantee that a third-party DApp, contract or service is trustworthy. Requests with an unclear origin, unusually broad permissions, unexpected amounts or unexplained actions should be rejected until the source can be verified.
A simple checklist for gas turns a complex flow into a few details that can be verified independently. If a request cannot be explained, there is no need to continue simply to finish the process. Re-checking the network, source and contract details before acting is usually more effective than trying to resolve an avoidable on-chain mistake later.
Practical checks
- Confirm the network, account or source associated with gas
- Never share a seed phrase, private key or verification code
- Read the full request before approving an asset or permission change
What to verify before acting: fee markets
Place the concept back into a real on-chain workflow to see how networks, addresses, fees, confirmations and contracts relate to one another.
Understanding fee markets is less about memorizing a definition and more about knowing where it appears in a real workflow, which details deserve attention, and what can go wrong when the wrong network or request is accepted. imtoken frames the topic around practical decisions: confirm the account and network first, read the request carefully, and only then decide whether to continue.

How to make practical decisions: block confirmations
Place the concept back into a real on-chain workflow to see how networks, addresses, fees, confirmations and contracts relate to one another.

Common mistakes and risk signals: failed transactions
Place the concept back into a real on-chain workflow to see how networks, addresses, fees, confirmations and contracts relate to one another.

Review and ongoing management: transaction status
Place the concept back into a real on-chain workflow to see how networks, addresses, fees, confirmations and contracts relate to one another.

Requests with an unclear origin, unusually broad permissions, unexpected amounts or unexplained actions should be rejected until the source can be verified.
Good practice continues after the action is complete. Use the transaction hash to review on-chain status, confirm the expected network and recipient, and check whether an approval or DApp session remains active. Removing permissions that are no longer needed reduces unnecessary exposure and makes future reviews easier.
