Layer-2 technology such as Arbitrum, Optimism, and a bridge to the Avalanche ecosystem are changing the way investors, builders, and developers interact with various protocols.

DeFi remains one of the Crypto economy's fastest-growing sectors, as evidenced by increases in total value locked (TVL) on protocols. Over the last week, dYdX and Hegic were two of the biggest protocol revenue gainers.
