IDEXd is the official successor of AuraD and provides the same functionality and services based on the IDEX token. AuraD is no longer supported. Please visit our new repo for instructions on upgrading from AuraD to IDEXd.

AuraD is software that enables the IDEX community to stake AURA, serve parts of the IDEX production infrastructure, and earn fees for participation. AuraD is the first part of a comprehensive plan to decentralize the centralized components of IDEX. For complete coverage, motivation, and roadmap, see our most recent post on AURA Staking.

AuraD is currently beta software. It is under development and subject to frequent changes, upgrades, and bug fixes. We appreciate your help in providing feedback and working around rough edges as we build towards 1.0.

In order to be eligible to participate in Aura Staking, you must have a wallet that holds a minimum of 10,000 AURA for a minimum of 7 days. Dropping below a 10,000 AURA balance, even for a brief period, will reset the incubation period.

AuraD is designed to run on a computer or VPS that is continually connected to the internet with a stable IP address and inbound connectivity.

• 2GB+ memory
• 20GB+ storage

• Ubuntu 18.04 LTS
• Docker CE 18.09 (Installation Guide)
• Docker Compose 1.17.1 (Installation Guide)
• nvm (Installation Guide)
• Node.js 10.15.0, npm 6.4.1 (Installation Guide)
• Git 17.1 (Installation Guide)

AuraD is designed to support a wide range of systems, but for the beta we recommend sticking to these requirements and versions.

AuraD is distrbuted via the @auroradao/aurad-cli npm package with dependencies on Docker and Docker Compose.

All of the requrements provide first-rate installation documentation, but we've collected the key steps to get up-and-running here. Start with a freshly installed copy of Ubuntu 18.04.

Some VPS providers, such as Digital Ocean, set up new Ubuntu 18.04 instances with only the root user account configured. We recommend running AuraD as a regular user account rather than root. When you first log in, run whoami to check which user you are currently acting as. If the response is root, follow Digital Ocean's instructions on adding a user and adding sudo privileges in order to run AuraD.

Log out and log in to the new, non-root user account before proceeding.

1. Update packages

sudo apt update

2. Install dependencies that allow apt to install packages via https

sudo apt-get install apt-transport-https ca-certificates curl software-properties-common

3. Add Docker’s official GPG key:

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

4. Add the stable Docker repository to apt

sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"

5. Update apt to include Docker packages

sudo apt update

6. Install the Docker CE package

sudo apt install docker-ce

7. Confirm Docker is running

sudo systemctl status docker

The output should look similar to:

● docker.service - Docker Application Container Engine
   Loaded: loaded (/lib/systemd/system/docker.service; enabled; vendor preset: enabled)
   Active: active (running) since Mon 2019-01-07 16:59:51 UTC; 5min 12s ago
     Docs: https://docs.docker.com
 Main PID: 4076 (dockerd)
    Tasks: 15
   CGroup: /system.slice/docker.service
           └─4076 /usr/bin/dockerd -H unix://

8. Add your user to the docker group to avoid permissions issues

sudo usermod -aG docker ${USER}

9. Log out and log back in and docker commands will be available from the prompt

1. Install the Docker Compose package

sudo apt install docker-compose

1. Install build depenency packages

sudo apt install build-essential python

2. Install nvm

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh | bash

3. Log out and log back in and nvm commands will be available from the prompt
4. Install Node.js

nvm install 10.15

1. Install aurad-cli to start and manage AuraD

npm install -g @auroradao/aurad-cli

2. Configure a staking wallet

aura config

AuraD provides prompts asking for a staking wallet that contains at least 10,000 AURA for 7 days. Go to MyEtherWallet or your preferred wallet software to sign the challenge and provide the sig value to prove that you control the wallet.

AuraD employs a cold-wallet design so that staked funds never need to leave the staking wallet for maximum security.

3. Sync your Aura Node and start serving traffic

aura start

AuraD connects to the Ethereum network and downloads IDEX trade history data to serve to IDEX users. Depending on the resources of the underlying computer or VPS and network, the initial syncing process may take a few minutes to several hours.

TODO: documentation on forcing a full sync vs fast sync

In order to serve data to IDEX users, AuraD Nodes must be reachable from the public internet. Most home and office connections are not publicly reachable by default, so you may need to take steps like opening up specific ports on your router. AuraD requires public TCP access to port 8443, and has limits on how frequently a node can change IP addresses.

We recommend running AuraD on an always-on, contected machine or a cloud-hosted compute instance.

AuraD is design to require minimal maintenance once it is live. For details on managing AuraD

To inspect the current total AURA staked, you may query the public endpoint: https://reporting.idex.market/aurad/staked

Logs are the best source of information to understand what's happening with AuraD under the hood. To follow the AuraD logs

docker logs -f docker_aurad_1

Display your node's current status and earnings history

aura status

Aurad-cli

The currently running version of the client

Latest Version

Latest version of the client available. If different than the currently running version, "Update Available" will be displayed. Update instructions can be found in this README

Cold Wallet

Ethereum address of the wallet holding AURA tokens for staking

Staked AURA

The current AURA balance you are staking to earn credits. If you are staking > 10,000 AURA it will reflect immediately as long as your 10k minimum has incubated for 7+ days.

Notice: Any delays in updating your balance will be fixed at payout time based on the timestamp of the block in which you added the AURA.

Total Staking AURA

The current staked AURA balance across all active stakers (updated approximately once per minute)

Staking

Either “Online” or “Offline”, with the time the client last connected with IDEX

Current Period

Date and times of the current staking period. Periods run for 14 days starting on Mon 00:00:00 UTC and ending on Sun 11:59:59 UTC. Payouts are made in ETH at the end of each period, based on your credits earned during that period.

My Period Credits/ Total Period Credits

The number of credits earned by the staker this period, over the total amount of credits earned by ALL stakers this period. 1 credit = 10k AURA staked for 5 minutes while your node is “online”.

Last Period Earnings

Amount of ETH earned by the staker during the last period. Note that payouts less than $3 USD based on ETH spot price at period close are rolled over to the next period.

Notice: This will read “0.000000 ETH” immediately after a period has ended and will be updated once the period earnings are calculated and sent by IDEX. This happens with 48 hours of a period close.

Last Period Credits

The number of credits earned last period, over the total amount of credits earned by ALL stakers last period. Staker payout is calculated from these numbers.

Earnings History

Further Information

aura stop

aura restart

To upgrade AuraD, stop the service, upgrade @auroradao/aurad-cli, and restart the service.

$ aura stop
$ npm install -g @auroradao/aurad-cli
$ aura start

Occasionally an upgrade may require running aura config before it can start serving traffic.

AuraD ships with its own copy of the Parity Ethereum Client and uses Parity to load data from the Ethereum blockchain. To use a different Etheruem node, you can specify a custom RPC endpoint

aura start --rpc <RPC endpoint URL including port>
