Sonic Labs (previously Fantom) cofounder Andre Cronje believes that builders ought to keep away from utilizing layer 2 (L2) app chains. Appchains are custom-made L2 blockchains designed to fulfill an utility’s particular wants.
In an X publish, Cronje listed a number of disadvantages hindering the expansion of appchains. These drawbacks embody the excessive value of infrastructure, fragmented liquidity, and lack of help for builders.
Cronje famous that appchains lack infrastructure for deploying stablecoins, oracles, and institutional custody. Extra importantly, Cronje mentioned that the price of infrastructure is grossly underestimated.
In keeping with him, the prices of custody, exchanges, oracles, bridges, and so forth. are fairly excessive. Cronje’s group has already spent $14 million on such bills this yr, a big a part of which incorporates recurring prices.
Nonetheless, Hilmar Orth, the founding father of Gelato Community, has a distinct opinion. In keeping with Orth, builders can simply entry infrastructure by way of rollup-as-a-service suppliers (RaaS). Orth mentioned that RaaS suppliers and framework groups present a lot help to builders, opposite to Cronje’s claims.
Cronje additionally claimed that appchains result in fragmented liquidity compelled onto susceptible bridges.
Marc Boiron, CEO of Polygon Labs, famous that the AggLayer (aggregation layer) may probably resolve the difficulty by creating an interoperable community of appchains. Polygon’s AggLayer allows sovereign blockchains to share liquidity.
However, Orth famous that every rollup comes with its personal bridges and market makers. Subsequently, liquidity is more likely to accumulate in a small variety of chains with excessive whole worth locked (TVL). This implies the remaining chains will simply plug into that liquidity based mostly on demand.
Orth added that sooner zero-knowledge (zk) proofs will additional make transferring funds throughout rollups extra seamless.
Neighborhood and community results
In keeping with Cronje, appchains lack a neighborhood of builders and customers, which in flip “kills community results.” Boiron, nevertheless, said that community results can be “alive and effectively” on the AggLayer, which aggregates customers and liquidity. He wrote:
“So many frens contributing to the AggLayer and all are going to need to assist develop the pie.”
Orth, nevertheless, believes that apps are there to compete with one another for customers and are, due to this fact, not pals.
