Sixth verse, same as the first

Our bridge explainer sets out why this category recurs: a bridge holds pooled collateral, runs privileged logic to decide when to release it, and operates across two chains with no shared source of truth. Compromise the attestation and you withdraw without depositing.

Every bridge incident in our tracker — Ronin, Harmony, Nomad, Orbit Chain — failed on key management or message validation. None failed on cryptography.

The unglamorous mitigation

Reconciliation. If a system continuously compares locked collateral against circulating wrapped supply and alerts a human on divergence, a forged withdrawal is visible in minutes. Ronin’s went unnoticed for six days because nothing did that.
