Arbitrum TVL has hit $2.2B, increased over $0.7B in 1 day, up 3269.9% over the past week.

tldr; The Arbitrum network has attracted over $2 billion of capital and is doing $100’s of thousands of dollars of daily fee revenue, has already hit their soft transaction limits and has seen unique addresses on the network balloon to over 70,000 - all of this in just 13 days of being live on mainnet. Since Arbitrum is permissionless to deploy to, a few "yield farms" were deployed that offered users a really high yield (at a high risk).
