September's big story was no doubt the UNI airdrop that all Uniswap users received. The resulting hype led Ethereum to its highest ever transactions in one day! In other news, the push for ETH 2 goes on while hacks/exploits continue to occur.

At Etherscan, we heard your overwhelming response and created the Yield Farms list. Please remember to DYOR before engaging with any of the farms. We also added address gas fee analytics (you can see how much gas you've burnt chasing yields!) and improvements to the UI.
