   @AlexanderFreihaut V3 support is being worked on in #106, but there are a few blockers that I need to get through.

   Tests for V3 are now passing on master! https://github.com/shanefontaine/uniswap-python/runs/2601585038

   V1 and V2 tests still have a few failures though, so we might wait with a new release until at least the V2 tests are passing as well.

   Any idea when Creating/Closing liquidity positions on v3 will be implemented? Very much looking forward to that!

   @rmurray2 I'm working on that, although the code is not based upon uniswap-python, but rather tries to follow the official uniswap-v3-sdk (javascript). If anyone is interested to participate in this project, I'll be more than happy. Creating/Closing position is almost ready.
