SLIP39.app: A Wallet Backup With a Recovery Quorum

slip39.app ↗ · Useful Tools · score 84.0
Open: public page gives enough substance to understand the site $Paid: pricing, booking, ecommerce, subscription, or paid access is visible ADAds: visible ad load or ad-supported content Pretty: notable design, copy, craft, or presentation Pro: polished, finished-feeling, serious, or operationally mature Niche: specific audience, workflow, or unusually focused use case Human: personal, local, community, civic, handmade, or real-person signal !Suspicious: scammy, spammy, trust theater, finance fog, or credibility concern

An offline browser tool that splits BIP39 wallet mnemonics into SLIP-0039 Shamir shares and restores them from a chosen quorum.

Why it surfaced

This is unusually explicit about its security boundaries: the page says it blocks network connections with a Content-Security-Policy, tells users to verify the file hash and disconnect before entering secrets, and links to readable, dependency-free source code. It also includes self-checks, recovery drills, and address derivation so users can verify a backup rather than simply trust the interface.

Ice Does Not Count

August 12’s newborn domains include a rule-bound archive of enormous sodas, 27 family stories cut from one afternoon, a disaster-supply map with a 24-hour freshness rule, and an ocean bell that rings only when six conditions agree.

This is one of 1,000 discoveries in the 2026-08-12 Domain Arrivals issue.
