Unichain, which has been online for two months with little attention, suddenly experienced a turning point on April 15th. The $5 million UNI liquidity incentive launched by Uniswap Labs and operated by Gauntlet attracted $22.23 million in cross chain capital injection within just 24 hours, and TVL skyrocketed to $267 million in two days, jumping to fourth place in Layer2. Unichain is not a short-lived "hair picking" chain, it relies on Uniswap, focuses on high performance and low cost, and is positioned as "L2 born for DeFi". Unichain has achieved a block output of 1 second, with a cost reduction of 95%. The ecosystem has integrated over 100 projects such as Circle and Lido, and the infrastructure of Unichain is basically complete. The core of this round of outbreak lies in a high, short-term, and precise incentive mechanism: $5 million is concentrated in 12 liquidity pools and distributed within two weeks. According to Gauntlet's estimation, every $1 incentive can leverage $3550 in TVL, and Unichain's performance this time has exceeded expectations. But it has also raised concerns about liquidity "involution", with tens of millions of funds in some pools concentrated in the 0.99981 range, with daily returns of less than $2K. The surge in TVL is a return reaction of funds to "steady returns" and a rehearsal for Uniswap's transformation into an "infrastructure player". By leveraging the Hooks mechanism introduced by V4 in conjunction with Unichain, Uniswap aims to create a highly customized, low latency, and decentralized DeFi home ground. Currently, Uniswap DAO has approved an annual incentive budget of $60 million and a grant budget of $95.4 million to support Unichain and V4. The protocol fee switch is also being pushed forward, and once activated, UNI holders may experience real value capture. From motivation to successful ecological cold start, Unichain is becoming a key pivot for Uniswap to reshape the DeFi landscape. But next, can it retain short-term funds as long-term users? Can it truly attract developers to build here? It is still the key to determining the success or failure of its' new home on the chain '.
