Why Do Tokens with the Same CA Have Different Prices?

On decentralized exchanges (DEXs), each trading pair operates with its own liquidity pool, and the ratio of the two tokens in that pool sets the trading price. If a pool has low liquidity, buying or selling a large amount of tokens can greatly affect the price, causing discrepancies. For instance, you can see differences between Uniswap's V2 and V3 pools. You can find different pools by looking up their specific pool addresses.
