Overview

This AMM implements the constant-product formula (x * y = k) popularized by Uniswap. It allows trustless token swaps between two assets using a liquidity pool.

Key DeFi concepts:

  • Constant product formula: Price determination via x * y = k
  • Liquidity provision: Add/remove liquidity and receive LP shares
  • Token swaps: Exchange one token for another with automatic pricing
  • Fee collection: Swap fees distributed to liquidity providers

This is one of the most complex SolScript examples, showing that full DeFi primitives can be built in Solidity syntax on Solana.
