Uniswap V3 is a decentralized exchange (DEX) protocol using Automated Market Makers (AMM) with concentrated liquidity ranges. Used by smart contract developers, DeFi engineers, and protocol designers building trading protocols, liquidity management, and DEX integrations. Salary: $150–220k. Learn in 8–12 weeks. Sits alongside Solidity, OpenZeppelin, and DeFi fundamentals.

什么是 Uniswap V3 AMM

Uniswap V3 is a decentralized exchange (DEX) protocol using Automated Market Makers (AMMs) with concentrated liquidity. Liquidity providers choose price ranges for their capital, enabling higher capital efficiency and customizable risk profiles. Traders swap tokens via pools; the protocol executes swaps instantly. You interact with Uniswap V3 via smart contracts on Ethereum and other chains. You can add/remove liquidity, swap tokens, or integrate the protocol into your own contracts. The SDK simplifies interactions; the core contracts handle pool mechanics, pricing, and swaps.

❓ 常见问题

What's Uniswap V3 and why is it different from V2?

V2 had full-range liquidity (LP funds spread across all prices). V3 uses concentrated liquidity: LPs choose price ranges, concentrating capital for better returns but with more risk (impermanent loss). V3 is more capital-efficient and customizable.

How do I add liquidity to a Uniswap V3 pool?

You call the NonfungiblePositionManager contract with token amounts, desired price range (tickLower, tickUpper), and slippage tolerance. It mints an NFT representing your liquidity position.

What's impermanent loss in V3?

Impermanent loss happens when prices move outside your LP range. If you provide liquidity at $100–$110 and price moves to $120, you're left holding tokens at unfavorable ratios. V3's concentrated liquidity can reduce IL but also increase it.

Can I integrate Uniswap V3 into my own contract?

Yes. Use the Uniswap SDK or call contracts directly (swap via Router contract, add liquidity via PositionManager). Many protocols build on Uniswap for swaps and pricing.

What's a tick and why does it matter?

Ticks are price intervals (0.01% apart). Your liquidity range is defined by tickLower and tickUpper. Ticks determine precision and gas cost. Understanding ticks is key to Uniswap V3.
