Stable

• Cosmos-SDK v0.50.x, CometBFT v0.38.x, ABCI 2.0
• Ethermint with Precompiles (ERC20, WIP: Issuance, Staking, Distribution)
• epochs and inflation module
• budget and govshuttle module for farming use cases
• restriction module for blocklisting

Install stabled

Clone git repository

git clone https://github.com/b-harvest/basechain.git
cd basechain/cmd/stabled
go install -tags ledger ./...
sudo mv $HOME/go/bin/stabled /usr/bin/

Generate and store keys

Replace <keyname> below with whatever you'd like to name your key.

• stabled keys add <key_name>
• stabled keys add <key_name> --recover to regenerate keys with your mnemonic
• stabled keys add <key_name> --ledger to generate keys with ledger device

Store a backup of your keys and mnemonic securely offline.

Then save the generated public key config in the main Stable directory as <key_name>.info. It should look like this:

pubkey: {
  "@type":" ethermint.crypto.v1.ethsecp256k1.PubKey",
  "key":"############################################"
}

You'll use this file later when creating your validator txn.

Set up validator

Install stabled binary from Basechain directory:

sudo make install

Initialize the node. Replace <moniker> with whatever you'd like to name your validator.

stabled init <moniker> --chain-id stable_2200-1

If this runs successfully, it should dump a blob of JSON to the terminal.

Download the Genesis file:

wget https://raw.githubusercontent.com/b-harvest/basechain/abci2.0/develop/Networks/sample_genesis/genesis.json -P $HOME/.stabled/config/

_Note: If you later get Error: couldn't read GenesisDoc file: open /root/.stabled/config/genesis.json: no such file or directory put the genesis.json file wherever it wants instead, such as:

sudo wget https://raw.githubusercontent.com/b-harvest/basechain/abci2.0/develop/Networks/sample_genesis/genesis.json -P/root/.stabled/config/

Edit the minimum-gas-prices in ${HOME}/.stabled/config/app.toml:

sed -i 's/minimum-gas-prices = "0astable"/minimum-gas-prices = "0.0001astable"/g' $HOME/.stabled/config/app.toml

Add persistent peers to $HOME/.stabled/config/config.toml: sed -i 's/persistent_peers = ""/persistent_peers = "ec770ae4fd0fb4871b9a7c09f61764a0b010b293@164.90.134.106:26656"/g' $HOME/.stabled/config/config.toml

Set stabled to run automatically

• Start stabled by creating a systemd service to run the node in the background:
• Edit the file: sudo nano /etc/systemd/system/node.service
• Then copy and paste the following text into your service file. Be sure to edit as you see fit.

[Unit]
Description="Stable Node"
After=network.target

[Service]
Type=simple
User=root
WorkingDirectory=/root/
ExecStart=/root/go/bin/stabled start --trace --log_level info --json-rpc.api eth,txpool,net,debug,web3 --api.enable
Restart=on-failure
StartLimitInterval=0
RestartSec=3
LimitNOFILE=65535
LimitMEMLOCK=209715200

[Install]
WantedBy=multi-user.target

Start the node

Reload the service files:

sudo systemctl daemon-reload

Create the symlinlk:

sudo systemctl enable node.service

Start the node:

sudo systemctl start stabled && journalctl -u stabled -f

You should then get several lines of log files and then see: No addresses to dial. Falling back to seeds module=pex server=node

This is an indicator things thus far are working and now you need to create your validator txn. ^c out and follow the next steps.

Create Validator Transaction

Modify the following items below, removing the <>

• <KEY_NAME> should be the same as <key_name> when you followed the steps above in creating or restoring your key.
• <VALIDATOR_NAME> is whatever you'd like to name your node
• <DESCRIPTION> is whatever you'd like in the description field for your node
• <SECURITY_CONTACT_EMAIL> is the email you want to use in the event of a security incident
• <YOUR_WEBSITE> the website you want associated with your node
• <TOKEN_DELEGATION> is the amount of tokens staked by your node (1astable should work here, but you'll also need to make sure your address contains tokens.)
