Wallet connections: what to expect
When you click “Connect Wallet” on OpenSea, your wallet will prompt you to approve the connection. This does not move funds by itself — it simply allows the site to read wallet addresses and balances. However, later actions (like signing approvals) can grant permissions to transfer tokens. Treat each approval as significant.
Limit token approvals
Many attacks rely on users granting blanket approval to marketplace contracts. Use tools that let you review and revoke approvals (for example, wallet settings or token-approval dashboards) and prefer one-time approvals over unlimited allowances. Revoke any approvals you do not actively use.
Session and device hygiene
Only connect from devices you control and keep browsers and wallet extensions updated. If you must connect from a mobile device, prefer official apps and avoid public Wi-Fi. Regularly clear old sessions where possible and disconnect unused sites from your wallet’s connected apps list.
Transaction safety
Before signing any transaction or message, verify the requested action. Beware of prompts that request signature approvals without clear context. Signing a transaction that approves token transfers can allow malicious contracts to move assets—only sign when you understand both the intent and the contract involved.
Recovery & incident response
If you suspect compromise, immediately disconnect your wallet, revoke approvals from a trusted device, and move unaffected assets to a fresh wallet (ideally a hardware wallet). Document the incident (timestamps, transaction IDs) to assist with investigations and reporting.
Maintaining vigilance in how you connect and approve actions on OpenSea is the single most effective way to prevent NFT theft and maintain control over your digital assets.
