Frequently Asked Questions
What is Price Impact vs Slippage?
Price Impact is the influence your own trade has over the market price of the asset. The larger your trade relative to the pool, the worse price you get. Slippage refers to the change in price during the delay between when you submit your transaction and when it is confirmed on the blockchain (often caused by other people's trades).
How does the x * y = k formula work?
Automated Market Makers (AMMs) like Uniswap v2 keep the mathematical product of the two token reserves constant. If you add Token A to the pool, Token B must decrease to keep the equation balanced. This curve ensures that as one token becomes scarce, its price increases exponentially.
How do I prevent Front-Running?
MEV (Miner Extractable Value) bots scan the mempool for trades with high slippage tolerance. If you set your slippage too high (e.g., 5%), a bot will sandwich your trade, artificially pumping the price right before you buy, causing you to pay 5% more, then dumping immediately. Keep your slippage tolerance as tight as possible (0.1% to 0.5%).
