This benchmark counts recorded incidents only. Absence from the registry does not prove a protocol is exploit-free: it means no incident matching the criteria (direct theft or loss of user funds via a security vulnerability) has been documented in the tracked sources as of the registry timestamp shown on each row. The registry is human-curated and updated when a new incident is confirmed. The registry date and source links are embedded in the harness.

How this pair was selected
Auto-generated pairs require: both providers in the same benchmark for seven consecutive days, at least 1000 samples per provider, observable third-party search demand, and a public /products/[slug] page on OCB. Editorially curated pairs (like this one) may publish early when search demand is high and data is accruing — panels with fewer than 100 samples are shown as provisional. The full pair ledger is versioned in the public repo.
