Security Considerations

While opensea.io is an established platform, these capabilities require extra vigilance.

Cryptocurrency Platform

opensea.io handles cryptocurrency transactions. Crypto transfers cannot be reversed once sent, making these platforms prime targets for phishing. Always verify you're on the exact official URL before entering credentials or approving transactions.

File Hosting

opensea.io allows users to upload and share files. Any file you download was uploaded by another user—not the platform operator. Scan downloads with antivirus software and only download from sources you trust.

User-Generated Content

opensea.io hosts content created by its users, not the platform operator. Individual posts, profiles, or pages may contain scams, misinformation, or phishing attempts that the platform hasn't yet detected or removed.

Remember: The platform itself is established, but even established platforms can be abused.
