 <p class="is-style-lead">Coinbase’s Institutional research team notes many bridge hacks occurred due to the complexities around source chain commit and cross-chain relay.</p>
 <p>Cyber incidents related to cross-chain bridges are likely to decrease in the foreseeable future as many protocols continue adopting rollup solutions alongside increased scrutiny on secure designs.</p>
 <p>According to Coinbase Institutional’s recent research report, most of the largest bridge hacks over the past few years happened due to the complexities around the signing and validation of messages by the relayers. These third-party services facilitate the transaction of data between different blockchains.</p>

 <p>Although the crypto industry lost more than $2 billion worth of crypto across 13 separate cross-chain bridge hacks in the first half of 2022, Han noted that the frequency and size of bridge-related hacks have dropped since then.</p>
