Protecting an NFT wallet means doing two different things: keeping the recovery phrase and signing keys private, and refusing transactions or permissions you do not understand. A hardware wallet can help protect key custody and show signing details, but it cannot make a dangerous approval safe once you authorize it.
Keep your recovery phrase private
Your recovery phrase can restore a self-custody wallet and gives whoever has it broad control over the wallet’s assets. Keep it private and offline. Never type it into a website, email, direct message, or support chat, and do not store a photo or cloud copy. No marketplace, ordinary dApp, or legitimate support representative needs it. OpenSea says it will never ask for the phrase, and MetaMask says it is needed only for initial setup confirmation, wallet restoration, or resetting a password. See OpenSea’s NFT safety guidance and MetaMask’s guidance on recognizing its genuine wallet.
If you think the phrase has been exposed, treat the wallet as compromised. Use verified official instructions to create a new wallet with a new phrase and move remaining assets to it. Revoking an approval does not neutralize a stolen recovery phrase.
Verify the wallet and website before connecting
- Download wallet software only from the provider’s official website or its official app-store listing. Do not install a wallet or “verify” a phrase because an unsolicited message tells you to.
- Reach a marketplace through a known official address or trusted bookmark, then check the URL before connecting or signing.
- Be wary of email-driven transaction prompts and unsolicited social-media messages. MetaMask says its genuine transaction popup is initiated by the user; a prompt with little contextual detail is a warning sign.
These checks reduce risk but do not prove a polished or verified-looking page is safe. OpenSea and MetaMask describe common impersonation and phishing risks in their safety guidance and wallet-authenticity guidance.

Choose a wallet setup that fits how you use NFTs
A software wallet, a hardware-backed wallet, and a separate wallet for lower-value interactions are different ways to manage exposure. No setup removes the need to review what you sign.
| Approach | Key custody and signing | Useful considerations |
|---|---|---|
| Software-only self-custody | Signing is handled through wallet software on an internet-connected device. | Convenient for frequent use, but the device and wallet interface are part of the security picture. |
| Hardware-backed self-custody | A dedicated device is used for signing and can display transaction details for confirmation. | Check whether the details shown are readable and whether the device, networks, wallet apps, and recovery process fit your needs. It does not prevent you from approving a malicious request. |
| Separate interaction wallet | Keep a lower-value wallet for unfamiliar or frequent dApp interactions, separate from a wallet holding more valuable assets. | Separation can limit what is exposed in one interaction, but each wallet still needs its own careful phrase handling and signing review. |
If you hold valuable assets or want a dedicated confirmation step, a hardware wallet can be a useful added layer. Before approving, inspect the spender and permission on the device screen when available. A compromised computer or misleading interface can still obscure a request, and a clear-looking prompt can still grant dangerous rights. Ledger’s ice-phishing guidance explains why users must assess the permission itself. Choose any device by custody design, transaction readability, network and wallet-app support, recovery procedure, and usability—not by an assumption that the hardware alone prevents phishing.

Understand NFT approvals before signing
An approval gives an app or smart contract permission to access or move an asset. Marketplaces may need approvals to list or transfer NFTs, so an approval is not automatically malicious. The important questions are which site initiated it, which spender receives permission, which asset it covers, and how broad or long-lasting the permission is.
- Specific-token approval: Permission is associated with an individual NFT.
- Collection-wide operator approval: A contract may be allowed to act on NFTs across a collection, creating broader exposure if the spender is malicious or compromised.
Prefer a narrower permission when the site offers one, and do not sign a request just because it appears during a mint, claim, or listing. MetaMask warns that deceptive signature requests may be used later; the absence of a gas-paying transaction does not establish that a signature is harmless. Read the site origin, spender, asset, and scope before signing, as described in MetaMask’s signature-phishing guidance and Ledger’s ice-phishing guidance.
Recommended Free Tools
Review and revoke Ethereum approvals you no longer need
For Ethereum, OpenSea’s approval guide describes using Etherscan’s Token Approval tool to review ERC-20, ERC-721, and ERC-1155 approvals and submit a revoke transaction. The tool is third-party, and revoking an approval requires a gas fee. Removing a marketplace’s NFT permission may mean you need to approve it again before using that marketplace. This checker does not establish coverage for every chain or every signature type.
- Open OpenSea’s Ethereum approval guide and follow its verified route to the approval checker.
- Confirm the wallet and network are Ethereum, then review the listed token or collection permissions and spender addresses.
- Select only permissions you intend to remove. Check the revoke transaction details in your wallet or signing device before confirming; expect to pay gas.
- After confirmation, verify the permission is no longer active. If you later use a service whose permission you removed, it may ask you to approve again.
Respond carefully if you signed a suspicious request
- Stop interacting with the suspicious site. Do not follow new links or instructions from the same message or account.
- From a clean, trusted device, review account activity and active approvals using current official guidance for your wallet and network.
- Revoke still-active approvals where possible, checking the chain and transaction details before signing. Revocation may not cover every signature style or permission.
- If the recovery phrase may have been disclosed, prioritize moving remaining assets to a newly generated wallet. If assets have already been transferred away, a revoke transaction cannot recover them.
Wallet interfaces, chains, and signature types differ, and some permit-style signatures have account-specific limits. MetaMask discusses these distinctions in its signature-phishing guidance. For a non-Ethereum network or a specific incident, use the wallet provider’s current official instructions rather than assuming an Ethereum approval checker applies.
