According to TechFlow, Sonic Labs CTO Andre Cronje wrote: “L2 as an application chain is illogical for developers:
There is little infrastructure support for deployment (e.g. stablecoins, oracles, institutional custody, etc.);
There were no foundations or labs to help;
Centralized architecture is vulnerable to attacks;
Decentralize liquidity and force it to pass through cross-chain bridges;
Lack of user and developer community;
Spend your time dealing with the above issues, not with applications and users;
Eliminate network effects;
Still requires long transaction confirmation times (some vendors are reluctant to work with them);
Developed alone (no collaborative team).
Lisk also severely underestimated the cost of infrastructure and compliance (browsers, hosting, exchanges, oracles, bridges, toolkits, IDEs, on/off ramps, native distribution and integrations, regulation, compliance). $14 million will be spent in 2024 alone, much of which is recurring costs.”
