A Huff implementation of UniswapV1.

To make it comparable to uniswap V1 i have to avoid using a Reentrancy guard this is just a POC of a minimal AMM with low gas consumptions build for the ETH Denver hackaton. DO NOT USE IT IN PRODUCTION.

Lets make a gas budget, lets imagine 1 create pair, 5 add liquidity, 5 remove liquidity and 30 swaps (per each type of swap);

• Uniswap: 1432129
• Huffswap: 1101268

Gas savings, around 30%
