When infrastructure like cross-chain bridges, oracles, or smart contracts breaks, it rarely affects just one user — it threatens funds across an entire chain. This is the site's largest category, focused on concrete verification methods for infrastructure risk: validator set changes, quote-staleness windows, audit coverage scope, and more.
