NFTs and Contract Addresses
NFTs and Contract Addresses is best treated as a verification point rather than a background detail.
Practical checks for nfts and contract addresses
A wallet address is generally public, but that does not make verification optional. After copying an address, compare key characters, confirm the network, and check the asset being sent. For a new destination, a small test can be reasonable when fees and transaction size justify it.
A smart contract is on-chain software. A wallet can display and sign a call, but it cannot guarantee that third-party contract logic is safe. Verify the network, contract address, intended function, and assets involved, while accounting for bugs, admin controls, upgrades, and external dependencies.
NFT ownership, contract permissions, and off-chain metadata are separate layers of information. Unknown NFTs can contain links designed to lure users into unsafe interactions. Verify the network and contract before transferring or approving, and avoid connecting a wallet merely to claim an unsolicited reward.
Receiving Unknown NFTs
When working with receiving unknown nfts, focus on what can be confirmed before you approve an action.

On-chain approvals can remain active after a website is closed or a wallet session is disconnected. Review the spender, token, allowance, and purpose before approving. Permissions that are no longer needed, have unclear origins, or are broader than necessary should be reviewed for revocation.
Transferring NFTs
The practical value of understanding transferring nfts is that it reduces ambiguity during real wallet use.

Good transaction records include the network, asset, public address, and transaction hash. Wallet balances can be affected by display settings or RPC availability, while on-chain records are better suited to determining whether a transaction succeeded and where an asset actually resides.

NFT Approvals
For nft approvals, the safest workflow separates what the interface shows from what the blockchain actually records.

Metadata and External Resources
Use metadata and external resources as a checkpoint: identify the network, the intended action, and the information you can independently verify.

Final check before you finish
- The address, network, and asset match the intended destination
- The signature or approval matches the action you intended
- No seed phrase, private key, or verification code has been shared
