Curve currently has about 25 chains online, but not all of them strictly belong to Layer 2. These chains include Arbitrum, Avalanche, Base, Celo, Gnosis, Hyperliquid, Ink, Po.

According to news from BJKW on August 2, CurveDAO member phil_00Llama submitted a proposal aimed at preventing this decentralized exchange from further expanding into other Ethereum Layer 2s, citing its lack of economic utility. The proposal states: "Layer 2 occupies the time of excellent developers. These chains need at least the same attention as Ethereum, but the returns are minimal. By cutting all development in this area, Curve can regain energy and move in a more productive direction." He pointed out, "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 times of low trading volume," the income generated by Curve's mining pool on the Ethereum Mainnet is 450.00 times that of all its Layer 2 deployments combined. This proposal was made following a similar move by Aave co-founder Marc Zeller, who stated in mid-July that despite passing a temporary check vote, the lending protocol should stop its deployment on Bitcoin Layer 2 BOB. According to DeFiLlama, Curve is currently live on about 25 chains, but not all chains are strictly Layer 2, including Arbitrum, Avalanche, Base, Celo, Gnosis, Hyperliquid, Ink, Polygon, Sonic, among others.
