How are token prices determined?

Token prices are determined by the amount of each token in a pool.

The liquidity pool contract maintains a constant using the following function: x*y=k.

  • x = token0
  • y = token1
  • k = constant

 

Liquidity pools on the Uniswap Protocol require that the pool price is a constant K.

 

During each swap, a certain amount of one token x is removed from the pool for an amount of the other token y. To maintain k, the balances held by the smart contract are adjusted, which changes the price.
