He highlighted the susceptibility of decentralized finance to exploits, referencing significant breaches such as Drift's $295 million loss in April. Fletcher stressed the importance of addressing security and interoperability issues to prepare for a future with extensive on-chain activity. Dennis Bree from Morpho echoed these concerns, noting April as a peak month for DeFi hacks. He pointed out the necessity for understanding security vectors and regulatory challenges as institutions navigate blockchain-based assets. Bree mentioned that curators managing billions in assets are seeking clarity on digital vault management and accounting practices for blockchain transactions.
