Calculating how much Ether should be sent to a wallet depending on requested gas price, gas amount and confirmation time.

Working website

Installation

install dependencies

pip3 install -r requirements.txt

populate the config.py with:

• NODE_URL = the url of the node you want to connect to like "https://ropsten.infura.io/YOUR_API_KEY" or "http://localhost:8545" if you run parity or geth
• ETH_PRIVATE_KEY = Ethereum Private Key as string
• API_KEY = Random 30 characters long string (needed for flask front end)
• CACHE_INTERVAL = Positive integer for seconds specifying how often gas Prices will be updated

Usage

run the app

python3 app.py

send request to localhost with query parameters

available parameters are: gas_needed (1 - 4.000.000) tx_speed (slow, medium, fast) public_address (valid ethereum address)

you can switch to the infura branch to quickly test with an INURA node otherwise you can run a local parity node

when testing you can run the testScript.py to fire request at your localhost. The app takes upto 30 seconds before it can return the first gas prices.

example GET request:

curl http://localhost:8000/fill-wallet-for-gas?gas_needed=10000&tx_speed=medium&public_address=0x516F329EC1fF7BF6882dE762A14eb94491FA4D8d'
