🧪 Metaverse Metaverse Economy Simulation

This simulation models the economic engine behind virtual-world DeFi: a constant-product automated market maker pairing a metaverse currency (MTC) against a virtual land token (LAND). Two 3D reserve towers and a live x·y=k curve show exactly how a swap moves the pool along its pricing curve, why bigger trades incur more slippage, and how the 0.30% trading fee compounds into liquidity-provider reserves over repeated trades. A separate external-market-price control demonstrates impermanent loss — the value an LP gives up relative to simply holding both tokens once the pool's internal price and the wider market price diverge — the single most important risk concept in real DeFi liquidity provision, reproduced here with the actual formulas.
