What it means: the chance that no one is really hiring for this job.How to read it: 60% or higher means we think this is a ghost. Lower scores are less of a worry.How we score it: age, reposts, open roles vs team size, how fast jobs close, and whether pay is listed.Fine print: an estimate from public data, not a judgment of the company. Real jobs can score high, so treat it as a hint, not a fact.

The Vault targets financial institutions, asset managers, family offices, corporate treasuries, payment providers and other high-volume digital-asset businesses, and operates under regulated legal entities (e. g. , CySEC CASP for the EEA and VQF/Swiss oversight) and third-party audits like SOC 2 and ISO processes.
