# defi_py_mix
For all your DeFi needs
[You can see a smaller version of this here. ](https://github.com/PatrickAlphaC/aave_brownie_py)
In our `aave_borrow.py` script, we do the following:
1. Approve our `ETH` to be swapped for `WETH`
2. Swap an `amount` of `ETH` for `WETH`
3. Using `deposit_to_aave` we deposit the `WETH` as collateral
4. We use that collateral to borrow `DAI` with `borrow_erc20`
5. Then, we pay it back!
6. We can view the txs on etherscan to see what's going on under the hood.
In our `short_sell.py` script, we do the following:
1. Approve our `ETH` to be swapped for `WETH`
2. Swap an `amount` of `ETH` for `WETH`
3. Using `deposit_to_aave` we deposit the `WETH` as collateral
4. We use that collateral to borrow `DAI` with `borrow_erc20`
5. We then sell that `DAI` on the `Uniswap` DEX
This is essentailly a short sell on DAI!
# Setup
You'll need python, pipx, and eth-brownie installed.
Ideally you'd install with pipx
```bash
pip install --user pipx
pipx ensurepath
# restart your terminal
pipx install eth-brownie
```
Or, you could try it with pip.
```
pip install -r requirements.txt
```
Or, if you run into issues use pipx:
You'll need the following [environment variables](https://www.twilio.com/blog/2017/01/how-to-set-environment-variables.html). If you're unfamiliar with environment variables, you can set them all in your `.env` file:
```
export WEB3_INFURA_PROJECT_ID=YourProjectID
export PRIVATE_KEY="0xasdfasdfasdfasd..."
```
- `PRIVATE_KEY`: Your Private Key from your Wallet. *Note: If using metamask, you'll have to add a 0x to the start of your private key.
- `WEB3_INFURA_PROJECT_ID`: Your connection to the blockchain. You can get a URL from a service like [Infura](https://infura.io/)]. Right now it is hard coded to work with infura, but you can modify it however you want using `brownie networks modify`.
> Note: DO NOT SEND THESE TO GITHUB!!!
And last, be sure to check the aave_dai_token if you're using a [testnet DAI token](https://docs.aave.com/developers/deployed-contracts/deployed-contracts0). Aave sometimes changes the token they use on testnet to keep liquidity, [please check here for reference](https://aave.github.io/aave-addresses/kovan.json).
Also, feel free to check the [Aave docs](https://docs.aave.com/developers/the-core-protocol/lendingpool) as well, to learn more about the tools we are using.
# Quickstart - kovan
1. [Get some kovan ETH](https://faucet.kovan.network/)
2. Get some WETH
```
brownie run scripts/get_weth.py --network kovan
```
3. Run the script!
```
brownie run scripts/aave_borrow.py --network kovan
```
# Quickstart - mainnet-fork
Optional for running locally:
If you want to run locally, you can install `ganache-cli` and `yarn`. Here is where you can [install yarn.](https://classic.yarnpkg.com/en/docs/install/#mac-stable)
```
yarn global add ganache-cli
```
Then, you can run `ganache-cli --fork YOUR_INFURA_URL_HERE`, or just `brownie run --network mainnet-fork`
1. Get some WETH, borrow, and repay!
```
brownie run scripts/aave/aave_borrow.py
```
Or, to test short selling:
```
brownie run scripts/swap/short_sell.py
```
