Launch Date: They are targeting an L1 Ethereum mainnet launch on May 5, with an L2 deployment on Optimism set to follow shortly after.
Major Features: Concentrated liquidity: giving individual LPs granular control over what price ranges their capital is allocated to. Individual positions are aggregated together into a single pool, forming one combined curve for users to trade against
Multiple fee tiers: , allowing LPs to be appropriately compensated for taking on varying degrees of risk
Other Features *LPs can provide liquidity with up to 4000x capital efficiency relative to Uniswap v2, earning higher returns on their capital
*Capital efficiency paves the way for low-slippage trade execution that can surpass both centralized exchanges and stablecoin-focused AMMs
*LPs can significantly increase their exposure to preferred assets and reduce their downside risk
*LPs can sell one asset for another by adding liquidity to a price range entirely above or below the market price, approximating a fee-earning limit order that executes along a smooth curve
A LOT more is included as well. On top of this, gas fees will be cheaper on v3 than on v2, and will be significantly cheaper on the L2 Optimism version.
