A number of mainstream DeFi projects including MakerDAO, SushiSwap, Balancer, and Yearn simultaneously posted "fist bump" pictures using project-specific color backgrounds on Twitter. The market speculated that this may be related to "Arbitrum is about to release tokens" or "multiple DeFi projects will form a coalition". DeFi composable leverage protocol Gearbox Protocol tweeted that this is just a DAO flash mob conducted by some DeFi projects together, and it is also the first collaborative attempt, but marketers may be able to prepare something cool for Monday.
