Overview

See the technical note Liquidity Math in Uniswap v3 and the Uniswap v3 whitepaper for the description of the purpose of this code.

For a Juperter Notebook version of the code, see yj's work here: https://github.com/uniyj/uni-v3-peri/tree/main/atiselsts-uniswap-v3-liquidity-math.

Have questions? Feel free to contact me via email [email protected] or DM (https://twitter.com/atiselsts, https://t.me/atiselsts). I'm also offering paid consultations on this topic.

Installation and usage

Some scripts need the gql Python module. Install this dependency with:

pip install -r requirements.txt

Execute from the command line, for example with:

./subgraph-liquidity-range-example.py

Example outputs

Example output of uniswap-v3-liquidity-math.py

Example 1: how much of USDC I need when providing 2 ETH at this price and range?
amount of USDC y=5076.10
p_a=1500.00 (75.00% of P), p_b=2500.00 (125.00% of P)

Example 2: I have 2 ETH and 4000 USDC, range top set to 3000 USDC. What's the bottom of the range?
lower bound of the price p_a=1333.33

Example 3: Using the position created in Example 2, what are asset balances at 2500 USDC per ETH?
Amount of ETH x=0.85 amount of USDC y=6572.89
delta_x=-1.15 delta_y=2572.89
Amount of ETH x=0.85 amount of USDC y=6572.89
