Foresight News reports that Uniswap has announced the launch of the Uniswap v4 Swap Router and has pledged to donate $35,000 to Ross for the development of a router optimized for v4, serving as an alternative to the universal router. With the support of Sauce, the community router (UniswapV4Router04) is now open to developers, aimed at reducing the learning curve for v4 integration. It can act as a semantic converter for the v4 architecture.
