New research from Uniswap has revealed that Arbitrum, an Ethereum layer 2 scaling solution, has been more profitable for liquidity providers compared to other layer 2 networks. The study found that due to Arbitrum's shorter block times, arbitrageurs pay higher fees to liquidity providers at the same gas price, and prices remain fresher. This shorter time frame translates into increased profits for liquidity providers utilizing Arbitrum.
New @Uniswap research! Shorter block times made Arbitrum more profitable than other L2s: 1ļøā£Ā Arbitragers pay more fees to LPs, at the same gas price 2ļøā£Ā Shorter block times means prices are fresher Shorter time = more profit for liquidity providers using Arbitrum
New research from @AustinAdams10 shows L2s arenāt just good for gas savings Compared to Ethereum, the data shows that on L2s: ā 97.5% of swappers get better pricing ā LPs see ~20% larger arbitrage returns ā Low gas leads to more capital efficiency rb.gy/6flvm0
