Security principle: users keep control of seed phrases and private keys. Legitimate staff do not request them, and addresses, networks, amounts, signatures, and approvals should be reviewed before confirmation.
On-chain transactions usually cannot be reversed unilaterally by a wallet. Third-party DApps, smart contracts, and services can introduce risk, so avoid unnecessary permissions and decide based on your own circumstances.
Choosing A Network: what it actually means
Before working through choosing a network, use a trusted device and network and define the outcome you expect. A website, support agent, or stranger should never need your seed phrase, private key, or verification code. For transfers or approvals, write down the intended network, destination, and amount first so you are not copying critical information under pressure. For choosing a network, avoid treating similar labels across different networks as interchangeable; the network, on-chain address, and contract context need to agree.
While completing choosing a network, use a deliberate sequence rather than clicking through prompts quickly. Confirm the active wallet account, verify the network, then review the address, amount, gas, or permission scope. For signatures, identify the request type and read the available details. If the purpose cannot be explained, reject the request and return to a trusted source. If a step involving choosing a network does not match expectations, return to the underlying data instead of relying on an unfamiliar link or someone offering to operate the wallet for you.
Practical check
- Confirm the active network and account before proceeding.
- Review addresses, amounts, contract targets, and permission scope as applicable.
- Keep the transaction hash or other public reference data for later verification.
Adding A Network: what to verify during use
While completing adding a network, use a deliberate sequence rather than clicking through prompts quickly. Confirm the active wallet account, verify the network, then review the address, amount, gas, or permission scope. For signatures, identify the request type and read the available details. If the purpose cannot be explained, reject the request and return to a trusted source. If a step involving adding a network does not match expectations, return to the underlying data instead of relying on an unfamiliar link or someone offering to operate the wallet for you.
After adding a network, verify the result instead of relying on a success animation. A transfer can be checked with its transaction hash; a DApp session can be reviewed to see whether it is still needed; token approvals can be inspected for target and allowance. This follow-up catches network mismatches, pending states, and permissions that should no longer remain active. Keeping the important parameters related to adding a network makes later verification easier because the result can be checked against public on-chain information.
Practical check
- Confirm the active network and account before proceeding.
- Review addresses, amounts, contract targets, and permission scope as applicable.

Understanding Gas: common mistakes and troubleshooting
After understanding gas, verify the result instead of relying on a success animation. A transfer can be checked with its transaction hash; a DApp session can be reviewed to see whether it is still needed; token approvals can be inspected for target and allowance. This follow-up catches network mismatches, pending states, and permissions that should no longer remain active. Keeping the important parameters related to understanding gas makes later verification easier because the result can be checked against public on-chain information.
If something looks wrong, avoid submitting the same action repeatedly. Duplicate attempts can add fees and make investigation harder. Capture the network name, transaction hash, destination, and any visible error, then separate possible causes such as congestion, insufficient fees, parameter mismatch, or a third-party service problem. Decisions about understanding gas should remain auditable: know whether a conclusion comes from protocol rules, public records, or a third-party service description.

- Confirm the active network and account before proceeding.
- Review addresses, amounts, contract targets, and permission scope as applicable.

Handling Network Mismatches: building a repeatable review habit
Before working through handling network mismatches, use a trusted device and network and define the outcome you expect.

For transfers or approvals, write down the intended network, destination, and amount first so you are not copying critical information under pressure.
