Bridge Security Risks
Common exploits.
Bridges Are High-Value Targets
Bridges hold enormous locked value, making them prime targets. Some of the largest crypto hacks in history were bridge exploits.
Understanding the common failure modes is essential for builders and users.
Compromised Signer Keys
Federated and multisig bridges depend on private keys held by validators. If enough keys are stolen, attackers can forge transfers and mint unbacked tokens.
The Ronin bridge hack (over $600M) stemmed from compromised validator keys.
