tokenlists 0.2.0

Python implementation of Uniswaps' tokenlists

py-tokenlists

Uniswap Token Lists implementation in Python.

Dependencies

• python3 version 3.8 or greater, python3-dev

Installation

via pip

You can install the latest release via pip:

pip install tokenlists

via setuptools

You can clone the repository and use setuptools for the most up-to-date version:

git clone https://github.com/ApeWorX/py-tokenlists.git
cd py-tokenlists
python3 setup.py install

Quick Usage

>>> from tokenlists import TokenListManager
>>> tlm = TokenListManager()

>>> tlm.available_tokenlists()
[]

>>> tlm.install_tokenlist("tokens.1inch.eth")
>>> tlm.available_tokenlists()
['1inch']

You can also author and test your own token list locally before publishing it:

tokenlists new ./tokenlist.json --name "My Token List" --keyword defi --keyword dex
tokenlists add ./tokenlist.json --chain-id 1 --address 0x0000000000000000000000000000000000000001 --name "Token" --symbol TKN --decimals 18 --tag stablecoin
tokenlists install ./tokenlist.json

If you omit required options from tokenlists new or tokenlists add, the CLI will prompt for the missing values. When a token is added to a list, the list timestamp is refreshed and the semantic version is bumped from major.minor.patch to the next minor version, following the token list update rules for additive changes.

Publishing is simply serving the generated JSON somewhere reachable by your users. Once hosted, install and verify it with tokenlists install <url>.

Token lookup order is controlled locally through pyproject.toml:

[tool.tokenlists]
order = ["My Preferred List", "Fallback List"]

HTTP downloads use httpx and honor the standard environment variables that HTTPX documents for restricted networks and custom trust stores, including HTTP_PROXY, HTTPS_PROXY, ALL_PROXY, NO_PROXY, SSL_CERT_FILE, and SSL_CERT_DIR.
