Aave crossing $50Bn is very significant. In 2010, Dodd-Frank declared any bank over $50Bn in assets a "Systemically Important Financial Institution" and added extra regulations. Many banks kept assets at $49Bn to avoid tripping it. Aave blew right past the $50Bn mark.

.@sherlockdefi and @blackthornxyz have helped secure recent Aave V3 versions. Good smart contract security has literally become systemically important to the traditional financial system.
