Core security principles
In the context of Token Approvals, spender is often one of the first details to verify. Do not rely on an interface label alone; compare it with allowance and contract address. Once an on-chain action is broadcast, network rules, block production, contract logic and finality determine what happens next, so a deliberate pre-action review is more useful than assuming a wallet can reverse the result later.
A practical way to understand allowance is to place it inside the complete flow. Identify where the request came from, verify contract address, and then inspect revocation together with any fee, permission or timing consequence. This helps separate interfaces that merely look similar from actions that actually refer to the same address, network, contract or transaction.
Each important field should be independently checkable. When contract address matters, compare the wallet view with a suitable block explorer or trusted network documentation. When revocation matters, ask whether it changes destination, authority or cost. When malicious contracts matters, consider whether the action creates an ongoing approval, a waiting period or a later verification step.
Many avoidable problems come from skipping verification rather than from one particular button. A consistent habit around revocation, malicious contracts and spender can reduce wrong-network transfers, copied-address errors, excessive approvals and confusion about transaction status. If the request cannot be explained in plain terms, delaying the signature or transfer is usually safer than continuing blindly.
spender — practical checks
- Confirm that the request source and current network match your intention.
- Verify the address, contract or permission target instead of relying on a label.
- Keep the transaction hash or result so the final state can be checked independently.

What to do when something looks wrong

If you suspect phishing, a malicious signature, or an unexpected approval, stop the flow, disconnect unnecessary DApp sessions, and re-check account and approval status from a trusted entry point. Seed phrases and private keys are controlled by the user; official staff should never ask for them.

imtoken will never ask for your seed phrase, private key or verification code. Verify address, network, amount, request origin, target and permission scope before transferring, signing or approving.
