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.
Receiving Addresses: what it actually means
Before working through receiving addresses, 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 receiving addresses, avoid treating similar labels across different networks as interchangeable; the network, on-chain address, and contract context need to agree.
While completing receiving addresses, 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 receiving addresses 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.
Network Matching: what to verify during use
While completing network matching, 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 network matching 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 network matching, 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 network matching makes later verification easier because the result can be checked against public on-chain information.

Amount Review: common mistakes and troubleshooting
After amount review, 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 amount review 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 amount review should remain auditable: know whether a conclusion comes from protocol rules, public records, or a third-party service description.

Gas Fees: security implications
If something looks wrong, avoid submitting the same action repeatedly. Duplicate attempts can add fees and make investigation harder.

Decisions about gas fees should remain auditable: know whether a conclusion comes from protocol rules, public records, or a third-party service description.

Transaction Hashes: building a repeatable review habit
Before working through transaction hashes, 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 transaction hashes, avoid treating similar labels across different networks as interchangeable; the network, on-chain address, and contract context need to agree.
While completing transaction hashes, 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 transaction hashes 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.
