Collectors face unique threats
High-value NFTs attract targeted scams. From fake listings to malicious scripts embedded in web pages, collectors must assume active threats. Use a layered defense: hardware wallets for signing, a separate “trading” wallet with limited funds for day-to-day activity, and a cold-storage wallet for long-term holdings.
Use hardware wallets where possible
A hardware wallet forces transaction confirmations on a physical device, so even if your browser is compromised, attackers cannot sign transfers without the device. When connecting hardware wallets, confirm the address on-device and enable any optional PIN or passphrase features for added protection.
Whitelist and approvals
Where available, enable marketplace withdrawal whitelists or use smart-contract-based approvals that limit spending allowances. Revoke blanket approvals and avoid “infinite approvals” that permit unlimited token spending — always prefer granular, one-time permissions.
Responding to a suspected compromise
If you suspect an approval or transaction you didn’t authorize, immediately revoke permissions via your wallet or a token approval revocation tool, move remaining assets to cold storage, and document evidence (screenshots, timestamps) to support any recovery attempts. Report the incident to the marketplace and relevant communities.
