Warnings [how to run]

branch mathc-v1 utilize vyper 0.2.12

If pip can't find 0.2.12, just git clone then python setup.py install locally.

Env:

mac
python3.6

I'm in 2021, Why I upgrade uniswap that was written in 2019 ?

Because:

Old toolchain not compile, 1.x vyper has lots of bugs, missing types when run..

My mac won't install old version 0.1.x vyper...

There is not easy sandbox to test contract in python DSL (vyper...)

I can practice rewriting ERC20, Uniswap a bit like I did here !

Why v1 is bad

In whitepaper,

"Uniswap can be frontrun to some extent. This is bounded by user set minimum/maximum values and transaction deadlines"

Future

VB original idea with my comments.

whitepaper has more examples
