Running on a Host

Running a collateral auction keeper directly on a host

Prerequisties

Python 3.6+

Get RAI:

Buy RAI from Uniswap v2 or open a SAFE and generate it.

Clone:

git clone https://github.com/reflexer-labs/auction-keeper.git
cd auction-keeper
git submodule update --init --recursive

Install:

This creates a virtual environment and installs requirements.

./install.sh

1) Start virtualenv

source _virtualenv/bin/activate

2) Create a model file

Paste the following code into collateral_model.sh:

#!/usr/bin/env bash
while true; do
  echo "{}"
  sleep 120                   
done

NOTE: Currently, collateral auctions sell collateral at a fixed discount and so the keeper doesn't use a bidding model. This empty bidding model is simply a placeholder.

3) Create the keeper run file

Create a file called run_auction_keeper.sh and paste the following code in it:

#!/bin/bash
bin/auction-keeper \
     --model ./collateral_model.sh \
     --rpc-uri <ETH_RPC_URL> \
     --eth-from <KEEPER_ADDRESS> \
     --eth-key key_file=<KEYSTORE_FILE>

Then, substitute the following variables:

ETH_RPC_URL - the URL of the ethereum RPC connection

KEEPER_ADDRESS - the keeper's address. It should be in checksummed format(not lowercase).

KEYSTORE_FILE - your Ethereum UTC JSON keystore filename

For more information about this keystore format and how to generate them:

• Ethereum UTC / JSON Wallet Encryption

• keythereum

Finally:

chmod +x run_auction_keeper.sh

4) Start the keeper and enter your keystore file password

./run_auction_keeper.sh

$ ./run_auction_keeper.sh
Password for /keystore/key.json:
