Uniswap aims to create a more open and fair ecosystem for automated trading on decentralized infrastructure. This has been an amazing step forward from monopolizing, intransparent CEXes. However, it brought forward a whole additional set of problems based on the challenges of distributed systems. The latency of block times, transaction bottlenecks and more specifically the economic inefficiencies of LVR and impermanent loss have given birth to issues of unattractive profit margins (or even losses) for LPs and unfair trading for retail users. This is based on sandwiching (frontrunning and backrunning) and large CEX-DEX arbitrage trading dominated by searchers. There’s a range of approaches to solve these problems close to the application layer e.g. new McAMM (MEV capturing AMM) or LVR-minimizing Uni v4 hooks, but in the end the application layer will always be constrained by block times and available TX data through-put. Uniswap v4 and UniswapX introduce novel possibilities with hooks and intent/filler models but there’s further, deeper improvements which can and will happen. The Uniswap v3 deployment on Arbitrum has surpassed $500 million daily volume and it’s clear that L2/rollups will be the future for more economic trading in the ecosystem. This is where the novel upgrades with blobspace come into play. With the upgrade to EIP-4844 and if efficient allocation of blobspace is achieved, this will yield the potential to function as an accelerator for decentralized trading with more efficiency, reduced costs, faster finality and a flattened price curve. Uniswap is uniquely positioned to take advantage of this. Given the constant improvements in Uniswap v4, it can directly tackle the possibilities with blobspace and quickly launch on L2s including hooks to take advantage of fast preconfirmations with blobs to be used with LVR minimizing solutions in the making, such as Sorella. In addition, UniswapX can allow fillers to better compete with lower latency of tx settling and add the time component to further improve overall trading efficiency. With the introduction of hooks and fillers the diversity of custom trading solutions adapted to high tx throughput will drastically increase. Uniswap will be in a unique position to take advantage of such with its current research edge and innovation speed, but requires the necessary fundamentals, knowledge and data. The prototypes and data-transparency with this proposal will enable Uniswap to further cement its positioning as the leading DEX provider and infrastructure with the emerging L2/rollup world advancement due to blobspace, EIP-4844 and TX throughput scaling with DA (Data Availability) layer improvements.
