Andre Cronje, CTO of Sonic Labs, said in an article on X: "L2 as an application chain is illogical for developers:
- There is almost no infrastructure support for deployment (such as stablecoins, oracles, and institutional custody, etc.);
- There is no foundation or laboratory to help;
- The centralized architecture is vulnerable;
- Dispersed liquidity and forced to pass through cross-chain bridges;
- Lack of user and developer communities;
- Spend time dealing with the above problems instead of applications and users;
- Eliminate network effects;
- Still requires a long transaction confirmation time (some suppliers are unwilling to work with it);
- Develop alone (no friends).
The application chain also seriously underestimated the cost of infrastructure and compliance (browsers, custody, exchanges, oracles, bridges, toolkits, IDEs, on/off ramps, native issuance and integration, supervision, compliance). $14 million has been spent in 2024 alone, a large part of which is recurring costs."
