🔰BUILDING A TOKEN SWAP CONTRACT: UNDERSTANDING AUTOMATED MARKET MAKER FUNDAMENTALS If you want to build a token swap contract in Rust, you need to understand the core mechanics that power decentralized exchanges like Uniswap. The heart of it all is something called an Automated Market Maker, or AMM, and its most important formula is surprisingly simple. Think of a token swap contract like a lemonade stand with two big tanks. One tank holds lemons and the other holds sugar. The stand always keeps the product of lemons times sugar at a constant number. When someone comes to trade, they add lemons to one tank and remove sugar from the other. The formula automatically adjusts the price based on how full each tank becomes. If one tank gets very low, that asset becomes more expensive. If it gets very full, it becomes cheaper. This is the constant product formula, written as x times y equals k, where x is the amount of one token, y is the amount of the other token, and k stays the same. 👉To build this in Rust, you start by creating a smart contract that holds two token reserves. When a user wants to swap token A for token B, your contract calculates how much token B to send based on how much token A was added and the current ratio of reserves. After the swap, you update both reserve amounts. This automatic pricing is what makes decentralized trading possible without needing a traditional order book or a central authority.
