Curve currently has about 25 chains online, but not all of them are strictly Layer 2. These include Arbitrum, Avalanche, Base, Celo, Gnosis, Hyperliquid, Ink, Polygon, Sonic, etc.
CoinFeed reported on August 2nd that, according to The Block, CurveDAO member phil_00Llama submitted a proposal aimed at preventing the decentralized exchange from further expanding into other Ethereum Layer 2 chains, citing a lack of economic utility. The proposal reads, "Layer 2 takes up the time of talented developers. These chains require at least the same attention as Ethereum, but offer minimal returns. By cutting back on all development in this area, Curve can reclaim its energy and move towards more productive development." "I believe Curve should increase its investment in Ethereum, for example by focusing on broader adoption of scrvUSD within the Ethereum ecosystem." He noted that "during periods of low trading volume," Curve's mining pool on the Ethereum mainnet generates 450 times more revenue than all of its Layer 2 deployments combined. The proposal follows a similar move by Aave co-founder Marc Zeller, who stated in mid-July that the lending protocol should halt its deployment on Bitcoin's Layer 2 blockchain, BOB, despite passing a temporary review vote. According to DeFiLlama, Curve is currently listed on approximately 25 chains, not all of which are strictly Layer 2. These include Arbitrum, Avalanche, Base, Celo, Gnosis, Hyperliquid, Ink, Polygon, Sonic, and others.
