Why Gas Exists
A practical approach to why gas exists
Understanding “Why Gas Exists” starts with the real task described on this Gas & Transaction Confirmations page. The relevant concepts include gas, fee markets, transaction submission, pending state, block confirmation and transaction hashes. The goal is to separate interface hints from identifiers and states that can be independently checked through the active network, a block explorer, or the wallet itself.
Before confirmation, read or record the non-sensitive details that matter: gas-asset balance, fee parameters, transaction hash, block height, status and later confirmations. This creates a reliable troubleshooting trail if a transaction is pending or an interface displays an error, without resorting to repeated signatures, repeated submissions or disclosure of recovery material.
The main risk boundary includes poor fee settings, congestion, duplicate submissions and mistaking pending for a lost transaction. Knowledge from imtoken can explain how to inspect a request, but it cannot guarantee a third-party DApp, smart contract, bridge or service. Users should make a separate judgment about the specific counterparty and should never provide recovery material.
Gas Pricing
A practical approach to gas pricing
For “Gas Pricing,” the useful skill is not memorizing where a button appears. It is knowing the order of decisions around gas, fee markets, transaction submission, pending state, block confirmation and transaction hashes: identify the object, confirm the network and account context, understand the requested change, and decide what evidence will show that the action completed as intended.
Decide whether to continue only after checking gas-asset balance, fee parameters, transaction hash, block height, status and later confirmations. When a wallet, DApp, exchange interface and explorer appear to disagree, first resolve the network and on-chain object instead of assuming that every interface is referencing the same chain or asset.
Typical risks include poor fee settings, congestion, duplicate submissions and mistaking pending for a lost transaction. No “absolute safety” claim can remove these possibilities. A more realistic approach is to minimize secret exposure, keep approvals scoped to the intended use, verify the target and remove connections or permissions that are no longer needed.

Submission to Block Inclusion
A practical approach to submission to block inclusion
“Submission to Block Inclusion” is connected to the steps before and after it, so control, network context and on-chain outcome should be considered together. With gas, fee markets, transaction submission, pending state, block confirmation and transaction hashes in view, a user can distinguish a read-only request from a connection, signature, approval or transaction instead of treating every wallet prompt as equivalent.
A practical review can consistently cover gas-asset balance, fee parameters, transaction hash, block height, status and later confirmations. If one of these does not match the intended action, stop and re-check the source and destination before submitting again. Seed phrases, private keys and verification codes are never normal troubleshooting fields and should not be shared.
Include poor fee settings, congestion, duplicate submissions and mistaking pending for a lost transaction in routine maintenance instead of waiting for an incident. Review old approvals, keep the device environment trustworthy, verify domains and networks, and retain the public transaction information needed to independently check what happened.
Confirmations and Finality
A practical approach to confirmations and finality
Names and icons can look familiar in a “Confirmations and Finality” workflow without referring to the same on-chain object. For gas, fee markets, transaction submission, pending state, block confirmation and transaction hashes, verifiable identifiers are more dependable than visual similarity, particularly when several EVM-compatible networks or similarly named assets are involved.
An actionable checklist should include gas-asset balance, fee parameters, transaction hash, block height, status and later confirmations. Review intent before the prompt, read the prompt during confirmation, and verify the outcome afterwards with a transaction hash, public address, contract address or network state when applicable. These three checkpoints are more useful than a generic warning.
Problems in this area often come from poor fee settings, congestion, duplicate submissions and mistaking pending for a lost transaction. If the source is suspicious, the target is unclear or the request exceeds the task at hand, decline it and investigate. On-chain transactions generally cannot be unilaterally reversed by a wallet, so verification is more important than speed.

Failure Checks
A practical approach to failure checks
Finishing “Failure Checks” should not mean stopping at a success message. Use gas, fee markets, transaction submission, pending state, block confirmation and transaction hashes to check the conditions before submission, the request at confirmation time and the resulting state afterwards. That makes the workflow repeatable and easier to troubleshoot.
For a first attempt, rehearse the workflow using non-sensitive, verifiable information such as gas-asset balance, fee parameters, transaction hash, block height, status and later confirmations. Understanding what each field represents before an irreversible action or permission change is safer than mechanically copying a sequence of clicks.
Finally, distinguish “submitted” from “confirmed.” poor fee settings, congestion, duplicate submissions and mistaking pending for a lost transaction can affect the actual outcome or permission exposure. Use the relevant network record, explicit approval state and destination-service support information rather than unverified assurances as evidence.
