Approval security starts with four questions: who receives permission, what can they do, how much can they access, and for how long is the permission still needed? Unlimited approvals are not automatically malicious, but they increase exposure. Stop interacting with unverified contracts and consider revoking permissions that are no longer necessary.
Start with the core concepts
When learning about Approval Security, focus on how 授权对象, 权限范围 and 无限授权 relate rather than memorizing interface labels. Balances, addresses and statuses ultimately depend on rules and data on a specific network. Before acting, identify what you are handling, which network is involved and what outcome you expect.
In day-to-day use, 权限范围 often determines whether an action can complete as intended, while 恶意合约 can affect cost, confirmation time or permission scope. A useful routine is to review the source, verify parameters, confirm the request, perform the action and then verify the result independently.
无限授权 and 取消授权 may appear in the same workflow but they do not mean the same thing. When information is unclear, prefer verifiable on-chain data such as addresses, transaction hashes, block status and contract addresses. Similar-looking address formats do not guarantee that two networks are interchangeable.

Operations involving 取消授权 or 定期检查 deserve extra attention because permissions, irreversibility and third-party behavior can introduce risk. imtoken staff will never ask for a seed phrase, private key or verification code. Connecting a wallet does not mean every later signature or approval request should be accepted.
Practical checklist
- Verify 授权对象
- Verify 权限范围
- Verify 无限授权
- Verify 恶意合约
- Verify 取消授权
Details that are easy to confuse
无限授权 and 取消授权 may appear in the same workflow but they do not mean the same thing. When information is unclear, prefer verifiable on-chain data such as addresses, transaction hashes, block status and contract addresses. Similar-looking address formats do not guarantee that two networks are interchangeable.
Operations involving 取消授权 or 定期检查 deserve extra attention because permissions, irreversibility and third-party behavior can introduce risk. imtoken staff will never ask for a seed phrase, private key or verification code. Connecting a wallet does not mean every later signature or approval request should be accepted.
If the result differs from what you expected, troubleshoot 授权对象, 恶意合约 and 定期检查 in sequence. Confirm the network and address first, inspect on-chain status next, and then check for pending, failed or mismatched permissions. Repeating an action without understanding the cause can create extra fees or duplicate approvals.

Consistent habits matter more than remembering where a button sits. Build a personal checklist around 授权对象, 权限范围 and 无限授权, then use it before transfers, connections, signatures and approvals. Networks, DApps and third-party services change, so understanding principles is more durable than relying on one interface.
Security reminder
Never share a seed phrase, private key or verification code. Review addresses, networks and request details before signing, approving or transferring.
