01
Understand the role of Gas
In “Gas, Fees & Confirmations,” Gas is not an isolated idea. It works with Fee estimation and Failed transactions to determine what the user sees and where an action actually takes place. Once those boundaries are clear, interface prompts become easier to evaluate.
Gas measures computational resources used by on-chain operations, while the final fee depends on network rules and congestion. Pending does not automatically mean failed, and a failed transaction may still consume fees. This section therefore focuses on reasoning through the relationship between Gas, Fee estimation and the resulting on-chain state rather than memorizing interface locations.
A practical review habit
- Identify the active network and the object represented by Gas, not only its display name.
- When Fee estimation is involved, confirm that both concepts share the intended network and permission context.
- Keep public verification details such as a transaction hash when troubleshooting, but never expose recovery secrets.
02
How Fee estimation works with Pending transactions
Start with the goal of the action, then identify the network, address, contract or permission context represented by Fee estimation. Similar names, icons or page layouts do not prove that two environments are equivalent; network and on-chain identifiers provide stronger context.

03
Reviewing Pending transactions during an action
A repeatable review of Pending transactions can begin with the source and network, continue with the target and parameters, and end with the asset or permission change the action may create. Consistency is more useful than trying to confirm quickly.

Pending does not automatically mean failed, and a failed transaction may still consume fees. This section therefore focuses on reasoning through the relationship between Pending transactions, Block height and the resulting on-chain state rather than memorizing interface locations.

- When Block height is involved, confirm that both concepts share the intended network and permission context.
- Keep public verification details such as a transaction hash when troubleshooting, but never expose recovery secrets.
04
Common assumptions to avoid
A common mistake around Block height is treating display information as final on-chain truth, or assuming that a workflow that was safe once will be identical on another network, asset or DApp. Re-read the current request every time.

05
Make Failed transactions part of a routine
Making Failed transactions part of a routine means adding checkpoints before, during and after an operation: verify the conditions, read the request, then confirm the result through the transaction hash, network state or approval record.

Important security reminder
Seed phrases and private keys should remain under the user’s control, and official personnel will not request them or verification codes. Check the address, network and amount before a transfer; on-chain transactions generally cannot be unilaterally reversed by a wallet. Third-party DApps and smart contracts carry risk, so review the spender and permission scope and consider revoking unused approvals.
Before you continue
Use a repeatable review routine
- Verify the active network and target address or contract
- Read the amount, fee, signature or permission scope
- Never send a seed phrase, private key or verification code to anyone
- Verify the result through a transaction hash or approval record
- If a request is unclear, stop and verify the source before continuing
