About

Harmony AutoBidder automatically manages BLS keys for your validator to ensure you stay within a slot range while you sleep. It polls for validator information regularly and decides to either remove or add bls keys to stay within a slot range. The polling interval starts slow and contracts as the end of the current epoch approaches.

If you've benefited from using this program please consider donating or delegating ONEs to RoboValidator at https://staking.harmony.one/validators/mainnet/one1x8fhymx4xsygy4dju9ea9vhs3vqg0u3ht0nz74 so we can continue to improve this software.

Setup

Install requirements

$ pip3 install -r requirements.txt

Download the hmy client if you haven't already

$ cd ~/
$ mkdir ~/harmony
$ cd ~/harmony
$ curl -LO https://harmony.one/hmycli && mv hmycli hmy && chmod +x hmy

You don't have to use ~/harmony but that's how the service is currently configured. See config.py if you'd like to modify the path settings. Also make sure $HOME/harmony is in your system path.

Create your passphrase.txt file

$ echo 'passphrase' > ~/harmony/passphrase.txt
$ chmod og-rw ~/harmony/passphrase.txt

Copy BLS .key and .pass files into .hmy/allkeys

$ mkdir ~/harmony/.hmy/allkeys
$ cp ~/harmony/.hmy/blskeys/*.* ~/harmony/.hmy/allkeys
$ chmod og-rw ~/harmony/.hmy/allkeys/*.*
$ # Copy any other bls .key and .pass files from other nodes to ~/harmony/.hmy/allkeys as well

Setup config.py

If you are running a node on shard 0 on the same machine you can set USE_REMOTE_NODE = False otherwise you need to set it to True since a lot of RPCs we use only work on shard 0.
Set VALIDATOR_ADDR to your validator's address
Configure TARGET_SLOT to your liking. The bot will try to adjust the keys in a way that puts you just at or above TARGET_SLOT.
If PREVENT_INEFFICIENT_BID is set to True the bot will try it's hardest to never overbid while keeping you elected.
MAX_VALIDATORS_PAGES is the maximum number of validator pages the client can scan for downloading validator info
You still need to make sure your nodes are setup to run with all the BLS keys assigned to the validator between epoch changes

Update bls_keys.py

Update BLS_KEYS to contain all your bls key string in order of highest priority. The keys will be added and removed as if this list was a stack.

BLS_KEYS = (
    "f82d30adadabaaaeba00406a5d607134343888dccf4fc45bdc22f02ad10df3ddeed1656a2a253262dae92095297e3f84", 
    "8be0121e5282071287886b07af678eefb67737f12d306c370f588d2612bf3020f9dc97fce63ee86c0ee3cd2153e43f90", 
    "2bcee590cb191a7bff14641fb0afdd6e07ee83b45e7247fce9dcf0fc10d8c7c3560dad54891cdf8bffff36e4a2c24f04", 
    "1c1d7ca4562ddda2cb456a766f86f487ff30bf2d3cbb692f359a29438b04cb6b79daf9241c44b514893076a14bea9984",  
)

The bls_keys.py file was separated out in order to avoid merge conflicts. If you want to do development you can run the following command so git will not track changes to the file.

git update-index --skip-worktree bls_keys.py

vStatsBot Integration By Fortune Validator

Add your vStatsBot token acquired by running /token command on the bot to the autobidder config.py file. Set the two variables to True or False ( VSTATS_ALERT_REMOVE_KEY, VSTATS_ALERT_OUT_OF_ELECTION)

Create a tmux session

$ tmux new-session -s autobidder
