Make an order through API CowSwap
python3 -m venv venv
source ./env/bin/activate
pip install -r requirements.txtYou will need to create your own .env file. A template exists here as .env.sample
from which you can make your own by running the command cp .env.sample .env and
filling in your own account details.
Set your network and private key in .env.
Fill the variables in the cow_swap method of ./main.py
source .env
python -m src.mainIf you run the script exactly as is with the public and private keys provided, you should receive an error from the orderbook API saying:
{"errorType":"InsufficientFunds","description":"order owner must have funds worth at least x in his account"}A collection of python scripts and services built as simple integrations with Gnosis Protocol v2
Initially inspired by Martin's script. This integration
is a simple bot which monitors the orderbook seeking open orders
between stable coins. Assuming that, on
average, USD stable coins are worth 1 USD, the bot is prepared to place a counter order
for any swap willing to trade x of token A for y of token B when x < y. It is
important to remember that execution fees must be factored into this decision-making
process so that the counter order placed should net a result of strictly more tokens
purchased than sold (including fees).
For this reason, the script is primarily intended to be run on xDai network where transaction fees are negligible.
To see the trading history of the bot currently running on xDai with this script check out this trade history table filtered by address 0xd2cc479be0512301d0b19c3c0a9300baa1e03758
Design an HTTP solver which allow people to "swap" LP tokens
In essence, the solver will fetch the open orderbook, filtering for orders whose buy or sell token is an LP token. It will then encode the interactions necessary to enter or exit liquidity from the corresponding pool.
In the event that there is a coincidence of wants (a.k.a. a CoW), the solver could match the orders directly to reduce the cost of execution. Note that, A CoW in this scenario corresponds to a simultaneous desire to provide and withdraw liquidity from a specific pool.
