Drachma Capital`s Chainlink Wrapper for Python

built by: jshuaaaa

Installation

1. git clone https://github.com/Drachma-Capital/drachma-chainlink-wrapper.git
2. cd ./drachma-chainlink-wrapper
3. pip install .

Usage

Now that we have installed the chainlink-wrapper I will show you how to setup the oracle client

from chainlink_wrapper import OracleClient 

This command will import the OracleClient from package

In order to use the client, setting up the environment takes two arguments like so

client = OracleClient(address, rpc)

The address is the address to the PriceFeed contract deployed live on the blockchain, and the rpc argument is the rpc url to connect to the blockchain that has the feed deployed

(BOTH ARGUMENTS ARE STRINGS)

We also have pre-deployed variables for some PriceFeeds are constantly adding more for easier use of this tool

EXAMPLE CODE SNIPPET TO GET LIVE PRICE IN USD

from chainlink_wrapper import OracleClient
from chainlink_wrapper.rpc import *
from chainlink_wrapper.token_pairs import *

client = OracleClient(moonriver_KSMUSD, moonriver_rpc)

client.price_usd_pair() # prints KSM price in usd value

NOTE: not all chainlink oracles are paired against usd, if the oracle is paired against ETH you will use the following function to get the price in usd:

client.price_eth_pair_to_usd()

and if you want to get the price denominated in eth

client.price_eth_pair()
