sfxprotocol[.]online

PhishDestroy identifies sfxprotocol.online as an active domain engaged in brand impersonation against Sei, a Layer-1 blockchain network. The domain mimics official Sei branding to deceive users into entering sensitive credentials or downloading malicious payloads. Cybersecurity teams should treat this domain as a high-risk threat vector due to its intent to exploit trust in the Sei ecosystem, particularly among developers and validators who may interact with protocol-related tools or interfaces.

This domain was flagged by PhishDestroy’s automated pipeline, revealing multiple red flags: it resolves to IP 163.61.188.9 and was registered through NAMECHEAP INC on April 28, 2026. As of this report, VirusTotal shows 3/95 detections, indicating it has not yet been widely blacklisted. The presence of a Let’s Encrypt SSL certificate suggests an attempt to appear legitimate, further increasing its deceptive potential. The impersonation of Sei—a growing blockchain platform—makes this domain particularly dangerous, as attackers often target emerging ecosystems where security monitoring lags.

Users who visited sfxprotocol.online or entered any information should immediately cease further interaction and revoke any credentials or API keys exposed. Run a full malware scan using updated antivirus tools and monitor accounts for unusual transactions or unauthorized access. Report the domain to your security team and platforms such as Google Safe Browsing, PhishTank, or the Sei Foundation’s security contact. Avoid downloading any files or connecting wallets to this domain. Always verify URLs against official Sei channels (e.g., sei.io, sei.network) before interacting.
