How gas works
How gas works is a practical part of understanding Gas & Confirmations. Gas represents the cost of network execution, while confirmations describe how a transaction becomes increasingly settled. Before acting, confirm that the active account, target network and intended outcome all match, then review the parameters shown in the request.
imtoken guidance focuses on information you can verify. When something is unclear, do not rely on a single line in a pop-up. Check the address, network, contract, transaction history and explorer data where relevant, then decide whether the action matches your intent.
For How gas works, a repeatable sequence is useful: verify the source and network, check the address or contract, review the amount, permission or fee, and keep a transaction hash when one is created. This does not remove every risk, but it makes decisions easier to explain and problems easier to trace.
Practical checks
- Verify the network and account before working with how gas works
- Double-check important addresses, contracts, amounts or permissions
- Never send a seed phrase, private key or verification code to anyone
Fee estimation
Fee estimation is a practical part of understanding Gas & Confirmations. Gas represents the cost of network execution, while confirmations describe how a transaction becomes increasingly settled. Before acting, confirm that the active account, target network and intended outcome all match, then review the parameters shown in the request.
Fee estimation within Gas & Confirmations is not an isolated feature. In practice it is shaped by network state, account permissions, transaction parameters and user decisions. Understanding those relationships first makes similar-looking screens and labels much less confusing.
For Fee estimation, a repeatable sequence is useful: verify the source and network, check the address or contract, review the amount, permission or fee, and keep a transaction hash when one is created. This does not remove every risk, but it makes decisions easier to explain and problems easier to trace.
Practical checks
- Verify the network and account before working with fee estimation
- Double-check important addresses, contracts, amounts or permissions
- Never send a seed phrase, private key or verification code to anyone
Transaction confirmation
Transaction confirmation is a practical part of understanding Gas & Confirmations. Gas represents the cost of network execution, while confirmations describe how a transaction becomes increasingly settled. Before acting, confirm that the active account, target network and intended outcome all match, then review the parameters shown in the request.
A useful way to think about Transaction confirmation within Gas & Confirmations is to separate what the interface displays from what the blockchain records. The wallet organizes information and submits requests, while the target network records the resulting state. Addresses, networks, contracts and transaction hashes are therefore important verification points.
For Transaction confirmation, a repeatable sequence is useful: verify the source and network, check the address or contract, review the amount, permission or fee, and keep a transaction hash when one is created. This does not remove every risk, but it makes decisions easier to explain and problems easier to trace.
Practical checks
- Verify the network and account before working with transaction confirmation
- Double-check important addresses, contracts, amounts or permissions
- Never send a seed phrase, private key or verification code to anyone
Pending & failed transactions
Pending & failed transactions is a practical part of understanding Gas & Confirmations. Gas represents the cost of network execution, while confirmations describe how a transaction becomes increasingly settled. Before acting, confirm that the active account, target network and intended outcome all match, then review the parameters shown in the request.
The risky part of Pending & failed transactions within Gas & Confirmations is often the surrounding context rather than the button itself: which network is active, which site initiated the request, what permission is being granted, and whether the amount and fee make sense. Turning those checks into a routine is more reliable than reacting to prompts one by one.
For Pending & failed transactions, a repeatable sequence is useful: verify the source and network, check the address or contract, review the amount, permission or fee, and keep a transaction hash when one is created. This does not remove every risk, but it makes decisions easier to explain and problems easier to trace.
Practical checks
- Verify the network and account before working with pending & failed transactions
- Double-check important addresses, contracts, amounts or permissions
- Never send a seed phrase, private key or verification code to anyone
