New Release ~ 6/25/23
- Many bugfixes
- argparse is now more intuitive
- check back soon, I am going to add out of box support for many more chains!
Swap assets on uniswap, sushiswap, and kyberswap. Easily can be modified to support any dex that is a direct fork of uniswap by modifying the json file `data/dex_contracts.json`.
This asciinema demonstrates swapping DAI to WMATIC (wrapped matic) on kyberswap. Note that sometimes dexes are weird about native assets that are not Ethereum, so you may have to swap your assets into a wrapped asset in order to do this programatically. I am not sure why that is, but solving it is one of the things on the TODO list.

To get running ...
- Copy .env.example to .env and put your infura endpoints in there
- Copy example_wallet.json to keys/default_wallet.json and add your address and key.
- FYI: If you want a cool vanity address like this one: 0xffffad719353ff7cba6c1799deae8ad8d94d8724 , check out my vanity address generator: https://github.com/darkerego/ethervain
- To add more known tokens that can be referanced by name, just add them to data/tokens_ethereum.json and data/tokens_polygon.json
- Figure out why in some cases we cannot swap native assets other than ETH
