SonicLabs' Chief Technology Officer, An dreCronje, stated in a post that "L2 as an application chain is illogical for developers: there is almost no infrastructure support during deployment (such as stablecoins, oracle machines, and institutional hosting); there is no foundation or laboratory to provide assistance; centralized architecture is vulnerable to attacks; decentralized liquidity is enforced through cross chain bridges; there is a lack of user and developer communities; time is spent dealing with the above issues rather than applications and users; network effects are eliminated; and longer transaction confirmation times are still needed (some vendors are unwilling to cooperate with it) @rdulion
