OpenSea — Wallet Security Tips

Protect your wallet and NFTs when connecting to marketplaces.

Understand Signatures & Approvals

Signatures approve actions — some are single txns, others are permissive approvals (e.g., "approve all").
Avoid blanket approvals like "approve all" for tokens; use explicit, limited approvals when possible.
Read the message content in the wallet before approving — if it looks odd, cancel and investigate.

Disconnect & Revoke

Periodically review connected sites in your wallet and revoke access to sites you no longer use.
Use token-approval revocation tools (onchain explorers or reputable revoke services) carefully — verify the tool before use.

Warning: Some revocation tools are scams. Only use well-known, audited services and double-check URLs.

Protect Your Wallet Keys

Use hardware wallets (Ledger/Trezor) for high-value NFTs — signatures must be confirmed on the device screen.
Never enter seed phrases into websites or apps. Keep recovery phrases offline and secure.
Use a separate wallet for marketplace interactions if you want to limit exposure.
