Core Security Principles
Approval safety starts with least privilege: grant only the asset, amount and contract access that the current task actually needs. The practical way to understand Approval Security is to place it inside a real user journey rather than memorize isolated terms. 审查 dapp 授权对象、额度、期限与不再使用的权限 should be checked before an action, during confirmation and again after completion. Verify the entry point and network first, read addresses, permissions, fees and request details at confirmation, then use on-chain records to validate the outcome.
Many mistakes around Approval Security begin with information that looks familiar: similar network names, address formats, token symbols or interface layouts. Prefer details that can be independently checked, such as the full domain, network name, contract address, transaction hash and a matching block-explorer record, instead of relying on icons, nicknames or screenshots. For Approval Security, break the task into small points that can be verified rather than continuing while the network, address, permission or transaction state is still unclear.
Pre-action check
Confirm that the page and network match the task, then review public addresses, assets, fees or permission details. A familiar interface is not a reason to skip the request details of a third-party DApp or smart contract.
Common Risk Scenarios
Long-lived large allowances can widen the impact of a future contract issue, so review permissions that are no longer useful.

imtoken treats user review as the final decision point for Approval Security. This site never asks for seed phrases, private keys or verification codes, and it does not promise that confirmed on-chain transactions can be reversed by the wallet. DApps, smart contracts, networks and third-party services each introduce their own risk boundaries.

How to Identify Suspicious Requests
Revoking a permission is an on-chain transaction and generally requires gas on the network where the approval exists. imtoken treats user review as the final decision point for Approval Security. This site never asks for seed phrases, private keys or verification codes, and it does not promise that confirmed on-chain transactions can be reversed by the wallet. DApps, smart contracts, networks and third-party services each introduce their own risk boundaries.
If the result differs from what you expected, preserve non-secret details such as the transaction hash, network and public address, then begin troubleshooting from on-chain state. Never send recovery information to someone claiming to provide support, and do not sign an unfamiliar request simply because it is presented as a fix. For Approval Security, break the task into small points that can be verified rather than continuing while the network, address, permission or transaction state is still unclear.
Post-action check
Confirm that the page and network match the task, then review public addresses, assets, fees or permission details. A familiar interface is not a reason to skip the request details of a third-party DApp or smart contract.

You are responsible for keeping seed phrases and private keys private. imtoken personnel will never ask for them. Verify address, network and amount before sending; confirmed on-chain transactions generally cannot be reversed by the wallet.
