Bridge Exploit

A bridge exploit is an attack on the software that moves assets between blockchains. A typical bridge locks tokens on one chain and mints a representation on another, so it must hold large balances and prove that each deposit really happened. That combination makes bridges concentrated targets: a flaw in signature verification, a compromised set of validator keys, or a faulty proof check can allow an attacker to mint unbacked tokens or withdraw locked reserves. Cross-chain bridges have historically been one of the most exploited parts of crypto infrastructure. Users can reduce exposure by preferring bridges with independent audits and public validator sets, avoiding leaving assets bridged longer than needed, and remembering that a wrapped token is only as sound as the bridge behind it.
