When reviewing On-chain components of an NFT, separate contract, token ID, and owner. They may appear in the same workflow, but they represent different layers of the action. On this NFT Basics & Wallet Interaction page, the goal is to build a verifiable mental model rather than depend on a single interface cue. Before approving anything, identify the network, the object being changed, and whether the request matches the task you intended to perform.
A useful routine is to review items in a fixed order: confirm token ID, verify owner, inspect metadata, and keep URI for later reference. If a page unexpectedly asks for contract, stop and verify the source instead of continuing simply because the workflow looks familiar.
From a security perspective, On-chain components of an NFT should be considered together with owner, metadata, and URI. A legitimate review flow does not require you to reveal a seed phrase, private key, or verification code. Requests involving contract or token ID can change permissions or asset state, so review them individually and reject anything you do not understand.
Why wallets can display NFTs
In practice, indexing often tells you whether you are in the right context, metadata affects the resulting state, and media resource helps with independent verification afterward. Do not rely only on a success message in the interface. Where on-chain state is involved, compare it with cache and network so you can distinguish presentation from the actual network result.
Why wallets can display NFTs also has failure modes. Congestion, incorrect parameters, insufficient balances, contract conditions, or third-party service changes can produce unexpected results. Start with the objective state of metadata, media resource, and cache before retrying. Repeated submissions without understanding the cause can add fees or duplicate actions.

Transferring an NFT
A useful routine is to review items in a fixed order: confirm receiving address, verify network, inspect contract, and keep token ID for later reference. If a page unexpectedly asks for gas, stop and verify the source instead of continuing simply because the workflow looks familiar.

A legitimate review flow does not require you to reveal a seed phrase, private key, or verification code.

| Item | Why it matters | Suggested action |
|---|---|---|
| receiving address | Helps verify that the network state or permission scope matches your intent. | Review before and after submission and keep a traceable reference. |
| network | Helps verify that the network state or permission scope matches your intent. | Review before and after submission and keep a traceable reference. |
| contract | Helps verify that the network state or permission scope matches your intent. | Review before and after submission and keep a traceable reference. |
NFT approvals
NFT approvals also has failure modes. Congestion, incorrect parameters, insufficient balances, contract conditions, or third-party service changes can produce unexpected results. Start with the objective state of single-token approval, operator approval, and marketplace contract before retrying. Repeated submissions without understanding the cause can add fees or duplicate actions.
When reviewing NFT approvals, separate operator approval, marketplace contract, and 撤销. They may appear in the same workflow, but they represent different layers of the action. On this NFT Basics & Wallet Interaction page, the goal is to build a verifiable mental model rather than depend on a single interface cue. Before approving anything, identify the network, the object being changed, and whether the request matches the task you intended to perform.
A useful routine is to review items in a fixed order: confirm marketplace contract, verify 撤销, inspect risk, and keep single-token approval for later reference. If a page unexpectedly asks for operator approval, stop and verify the source instead of continuing simply because the workflow looks familiar.
Unknown NFTs and phishing
From a security perspective, Unknown NFTs and phishing should be considered together with airdrop, malicious link, and signature bait. A legitimate review flow does not require you to reveal a seed phrase, private key, or verification code. Requests involving hide or do not interact can change permissions or asset state, so review them individually and reject anything you do not understand.
In practice, malicious link often tells you whether you are in the right context, signature bait affects the resulting state, and hide helps with independent verification afterward. Do not rely only on a success message in the interface. Where on-chain state is involved, compare it with do not interact and airdrop so you can distinguish presentation from the actual network result.
