No. PhishDestroy classifies failed-recipient-add.firebaseapp.com as a Base impersonation page (risk: high, 68/100); it was first detected on 2026-10-26. Treat the site as unsafe.
No. Do not connect a wallet, sign messages or approve tokens on failed-recipient-add.firebaseapp.com. Phishing sites ask for approvals (approve, setApprovalForAll, Permit2) that let the operator move your assets, and a confirmed transaction cannot be reversed.
Change every password you entered there and turn on two-factor authentication. If you connected a wallet or signed something, revoke the approvals and move the remaining funds to a new wallet; never share your seed phrase. Step-by-step help: emergency guide.

An estimated time describes an observation window. It does not prove a registrar action or the exact moment a site became unavailable.
Dated changes retained by the monitor and source collectors. Newest observations appear first; source states are not proof of a takedown.
Reachable
Source: availability monitor. Every retained observation remains separate, including records with the same date or evidence hash but different sources or DNS states. An unknown state is not proof that the site is offline.

This report combines saved page captures, registration and network records, scanner results and PhishDestroy reporting history. Each source keeps its own observation date. Open a source report to inspect the original result.
A capture documents what was shown. A scanner result records that provider’s assessment at the time of its check. Neither a valid certificate nor a zero-detection result is a guarantee of safety.
