Methodology

What the assessment covers

Entropy integrity: We verify your phrase was generated with sufficient randomness and does not originate from a known weak generator or compromised wallet build.
Breach exposure: Your phrase is checked against 4.2 billion compromised phrases recovered from public breaches, leaked backups, and monitored dark web markets.
Derivation health: We confirm your checksum and derivation paths resolve correctly, and flag any wallet configuration known to produce recoverable keys.
