11 public-record incidents across tracked venues. The pattern worth noticing: 11 of 11 ended with customers made whole — modern top-tier venues eat the loss from corporate funds. The venues that never appear in this table have either excellent key management or a short history; our security score weighs both.

Methodology: every value on this page is generated from the same dataset that powers our rankings, on the dataset date shown above. Estimates (spreads, network fees, staking rates) are modeled from venue tier and published schedules, not live feeds — treat them as comparable midpoints, and check the venue before moving size. Corrections: how we rank.
