Drop-off Rate
Also called Funnel Drop-off, Onboarding Abandonment Rate, Abandonment Rate
Drop-off rate measures the share of people who start an onboarding flow and don't finish it, and, more usefully, exactly which step they abandoned it at. A single overall completion number ("60% finish onboarding") tells a business much less than a step-by-step breakdown ("95% get past the welcome screen, but only 70% get past the document scan, and only 60% get past liveness"): the second version tells you where to actually spend engineering effort.
For identity verification specifically, the document-capture-plus-liveness step is widely observed to be the single biggest drop-off point in the whole funnel, for reasons that are mostly about friction rather than fraud: camera permission prompts people don't expect, poor lighting causing repeated re-scans, a device camera too low-resolution to read a document's fine print, an active-liveness gesture the user finds confusing or invasive, or simply enough small annoyances stacked up that the person gives up and abandons the app entirely rather than trying again. Every one of those users is a lost customer for the business running the flow, and every failed attempt that does get resolved usually lands in a support or Manual Review Queue, which is why drop-off rate and review-queue volume tend to move together.
Who actually built this
There's no formal originator here, funnel analysis and drop-off measurement are baseline product-analytics practice, applied across e-commerce checkout, account signup, and every other multi-step online flow long before identity verification existed as a distinct product category. Identity-verification vendors and industry researchers have specifically studied and published on where KYC funnels lose people, consistently landing on document-plus-liveness as the costliest step: an observation Solidus is repeating, not originating.
Solidus today
Solidus Verify's analytics dashboard computes a real funnel per organization, initiated, document captured, liveness completed, credential issued, and a breakdown of drop-off reasons pulled from actual failed and expired sessions, not synthetic demo data. It has no cross-customer benchmark to publish, and any individual organization's number is only as meaningful as the volume they've actually run through it.

Pass Rate is the closely related metric measuring completion among people who reach the end of the flow, rather than abandonment along the way. KYC and IDV are the processes this funnel measures. Credential Portability is the structural fix this metric motivates, reuse means fewer people ever have to face the document-plus-liveness step at all.
Where it comes from
Someone else specified this. Solidus assembles it.
A general funnel/conversion-analytics metric, the share of people who start a multi-step process and don't finish it, broken down by which step they left at, with no single inventor. It's standard vocabulary in web and product analytics generally, long before identity verification existed as its own software category. Identity-verification vendors and industry analysts apply the same idea specifically to onboarding, and commonly point to the document-capture-plus-liveness step as one of the largest single drop-off points in fintech and wallet sign-up funnels: a pattern Solidus did not discover and does not claim credit for first observing.
How to check this
Running on the test network. Not mainnet.
Not independently checkable by a stranger, the analytics dashboard lives behind account authentication, so there's no public number to curl or compare against. Stated honestly rather than inventing a headline figure.
