Wu said that Andre Cronje, director of the Fantom Foundation, tweeted that L2 is unreasonable for developers as an application chain: there is almost no infrastructure support (such as stablecoins, oracles, and institutional custody) when deploying, there is no foundation or laboratory to help, the centralized architecture is vulnerable to attack, disperses liquidity and forces the use of cross-chain bridges, lacks user and developer communities, increases the time cost of developers in dealing with infrastructure issues, kills network effects, still requires a long transaction confirmation time (some suppliers are unwilling to work with you), and develops alone (no friends). Cronje also pointed out that the application chain greatly underestimates the cost of infrastructure and compliance (blockchain browsers, custody, exchanges, oracles, cross-chain bridges, toolkits, IDEs, up and down conversions, native issuance and integration, supervision, compliance). He revealed that in 2024 alone, $14 million has been spent, a large part of which is recurring costs.
