openseapro-start3[.]vercel[.]app

This domain, openseapro-start3.vercel.app, was registered on February 21, 2026 through Tucows Domains Inc. and is observed to host a Vercel deployment that presently returns HTTP 451 with the page title “Deployment Unavailable”. The site presents a Google Trust Services / WR1 SSL certificate, indicating a valid TLS chain, and the hosting IP resolves to 64.29.17.3, an address owned by Amazon.com, Inc. (AS16509) located in the United States. Infrastructure fingerprints include the Vercel platform and HTTP Strict Transport Security (HSTS) headers, both typical of legitimate cloud‑hosted services.

The domain is flagged by 14 of 95 security vendors on VirusTotal and appears on a single public blocklist, PhishDestroy, which categorises it as a crypto‑related scam impersonating the OpenSea brand. The page title and the HTTP 451 response suggest the site has been taken offline, and no additional content has been captured. Consequently, the observable evidence is limited to registration details, hosting attributes, SSL provenance, and the blocklist indication.

Uncertainty remains regarding the actual payload or user‑interaction mechanisms that may have been employed before the takedown. Defenders should continue to block the domain at network perimeter, monitor for any resurrection of the host under the same IP or similar Vercel subdomains, and update detection rules to include the observed certificate issuer and HTTP status pattern. Ongoing vigilance is advised, especially given the recent creation date and the association with a high‑value NFT marketplace brand.
