Uniswap V2 on Polkadot¶

Uniswap V2 is one of the most widely deployed decentralized exchange protocols. Its Automated Market Maker (AMM) architecture enables permissionless token swaps, liquidity provision, and price discovery for any ERC-20 token pair.

The Uniswap V2 stack is split into two layers:

• V2 Core: The Factory and Pair contracts that implement the fundamental AMM logic, constant product pricing (x * y = k), and liquidity pool management.
• V2 Periphery: The Router contracts that provide user-facing functions for adding and removing liquidity, executing token swaps with slippage protection, and wrapping native ETH through WETH.

Polkadot Hub supports deploying these contracts with no modifications. The tutorials below walk you through deploying, testing, and interacting with each layer.
