May 5 is the day that Uniswap announced for the launch of its latest version 3 upgrade. The new version will introduce a number of new features targeting capital efficiency. Layer 2 scaling is not included in this upgrade but will be launched soon according to Uniswap Labs.
Some of the upgrades in version 3 include multiple fee tiers which allow liquidity providers to be compensated for taking on varying degrees of risk. There will be three separate fee tiers per pair according to their expected volatility, 0.05%, 0.30%, and 1.00%, offering greater protection against impermanent loss to liquidity providers.
There are also upgrades to the automated market maker bonding curves, which aggregate individual positions into a single pool to form one combined curve for users to trade against.
Uniswap founder Hayden posted a demo of the new user interface on May 4 which included a novel interactive liquidity simulator.
