Understand EVM and addresses first
“Understand EVM and addresses first” becomes clearer when it is reviewed across three stages: before, during, and after an action. Confirm “Identify the real EVM context” before starting, watch “Distinguish addresses from look-alike labels” while the request is active, and use “Do not skip the gas check” to verify the result afterward. Explain how the EVM, addresses, gas, smart contracts, tokens and approvals fit together—and why compatible networks still require separate checks. Skipping one of these stages can leave network mistakes, duplicate submissions, or persistent permissions unnoticed.A knowledge page should connect terms to observable on-chain evidence such as network state, transaction records, block confirmations, or contract permissions rather than leaving the concepts as abstract definitions.
Turn the same checks into routine maintenance: re-check the network after switching, confirm the address and amount before sending, read every signature request, record why an approval exists, and periodically remove permissions that are no longer needed. Security is the accumulation of these small controls rather than a single switch that makes every future request trustworthy. In EVM Networks, this check belongs specifically to “Understand EVM and addresses first”, so the conclusion should remain tied to the account, network, target, and permission discussed on this page rather than being copied from another workflow.
- Identify the real EVM context
- Distinguish addresses from look-alike labels
- Do not skip the gas check
Check gas before you begin
The central question in “Check gas before you begin” is cause and effect. Explain how the EVM, addresses, gas, smart contracts, tokens and approvals fit together—and why compatible networks still require separate checks. Understand what “Define the intended task first” can trigger, who controls “Confirm that gas matches the plan”, and how “Cancel when the request looks unexpected” can later be verified on-chain. Connecting those steps helps prevent a simple connection from being mistaken for an approval or a temporary interface state from being mistaken for a final blockchain result.
If the observed result differs from the plan, preserve public transaction or error information and stop approving additional requests. Avoid repeated confirmations under pressure and reject remote-control instructions from unknown parties. Re-check the network, account, contract, and source before deciding whether any new action is actually required.A knowledge page should connect terms to observable on-chain evidence such as network state, transaction records, block confirmations, or contract permissions rather than leaving the concepts as abstract definitions.

- Define the intended task first
- Confirm that gas matches the plan
- Cancel when the request looks unexpected
Review smart contracts during the action
Treat every confirmation in “Review smart contracts during the action” as a question rather than a formality. In EVM Networks, you should be able to explain which object is involved, which network is active, why “Review smart contracts as its own decision” is needed, what “Read the on-chain details shown by the wallet” can change, and whether “Do not rely on button text alone” still matches the original objective.

If those answers are not clear, guessing is not the next step; cancelling is. This is especially important with third-party services because protocol rules, contract implementations, and network conditions can change. Interface wording is helpful context, but it does not replace checking the actual account, network, contract, fee, and permission shown by the wallet. In EVM Networks, this check belongs specifically to “Review smart contracts during the action”, so the conclusion should remain tied to the account, network, target, and permission discussed on this page rather than being copied from another workflow.
- Review smart contracts as its own decision
- Read the on-chain details shown by the wallet
- Do not rely on button text alone
Common mistakes and risks in EVM Networks
A practical model for “Common mistakes and risks in EVM Networks” is verify first, authorize second, and review afterward. Explain how the EVM, addresses, gas, smart contracts, tokens and approvals fit together—and why compatible networks still require separate checks. Verify “Connection is not the same as signing or approval”, understand “Reject any request for a seed phrase or private key” before signing or submitting, and use “Treat unfamiliar third-party services cautiously” to confirm the outcome. This keeps the concepts in EVM Networks tied to observable actions rather than isolated definitions.
The same model applies to maintenance. Reassess permissions that are no longer used, re-check even familiar networks after switching, and keep the device and browser environment trustworthy. No normal workflow requires a seed phrase, private key, or verification code to be sent to support staff, a chat group, or a website form.A knowledge page should connect terms to observable on-chain evidence such as network state, transaction records, block confirmations, or contract permissions rather than leaving the concepts as abstract definitions. In EVM Networks, this check belongs specifically to “Common mistakes and risks in EVM Networks”, so the conclusion should remain tied to the account, network, target, and permission discussed on this page rather than being copied from another workflow.
- Connection is not the same as signing or approval
- Reject any request for a seed phrase or private key
- Treat unfamiliar third-party services cautiously
Use approvals to verify the result
The purpose of “Use approvals to verify the result” is not to memorize where a control appears on one version of an interface. Start with a checkable sequence instead. In EVM Networks, Explain how the EVM, addresses, gas, smart contracts, tokens and approvals fit together—and why compatible networks still require separate checks. Review “Verify with approvals or other public data” first, compare it with “Confirm the network and public address”, and then confirm “Remove permissions that are no longer needed”. Breaking the task into separate questions makes mismatched networks, targets, or permissions easier to spot before anything is submitted.A knowledge page should connect terms to observable on-chain evidence such as network state, transaction records, block confirmations, or contract permissions rather than leaving the concepts as abstract definitions.
A familiar logo, token name, or address format is not enough evidence by itself. Write down the intended account, network, destination or contract, expected fee, and permission change. If one of those pieces cannot be explained, cancel the request and return through a trusted entry point rather than relying on a screenshot or instructions from an unknown contact. In EVM Networks, this check belongs specifically to “Use approvals to verify the result”, so the conclusion should remain tied to the account, network, target, and permission discussed on this page rather than being copied from another workflow.
- Verify with approvals or other public data
- Confirm the network and public address
- Remove permissions that are no longer needed
Practical checklist
- Never enter a seed phrase, private key or recovery phrase into a website
- Official staff will not ask for your seed phrase, private key or verification code
- Check the address, network and amount before transferring
- Review every DApp signature request separately
- Review and revoke permissions you no longer need
