Join the Network

Hardware Specification​

Node operators should expect to provision one or more data center locations with redundant power, networking, firewalls, HSMs and servers.

The minimum hardware specifications are as follows, though they might rise as network usage increases:

6+ vCPU x64
32+ GB RAM
500 GB+ SSD

Install injectived and peggo​

See the Injective releases repo for the most recent releases. Non-validator node operators do not need to install peggo.

wget https://github.com/InjectiveLabs/testnet/releases/download/v1.12.9-testnet-1703762556/linux-amd64.zip
unzip linux-amd64.zip
sudo mv peggo /usr/bin
sudo mv injectived /usr/bin
sudo mv libwasmvm.x86_64.so /usr/lib

Initialize a New Injective Chain Node​

Before running Injective node, we need to initialize the chain as well as the node's genesis file:

# The argument <moniker> is the custom username of your node, it should be human-readable.
export MONIKER=<moniker>
# Injective Testnet has a chain-id of "injective-888"
injectived init $MONIKER --chain-id injective-888

Running the init command will create injectived default configuration files at ~/.injectived.

Prepare Configuration to Join Testnet​

You should now update the default configuration with the Testnet's genesis file and application config file, as well as configure your persistent peers with seed nodes.

git clone https://github.com/InjectiveLabs/testnet.git

# copy genesis file to config directory
aws s3 cp --no-sign-request s3://injective-snapshots/testnet/genesis.json .
mv genesis.json ~/.injectived/config/

# copy config file to config directory
cp testnet/corfu/70001/app.toml  ~/.injectived/config/app.toml
cp testnet/corfu/70001/config.toml ~/.injectived/config/config.toml

You can also run verify the checksum of the genesis checksum - a4abe4e1f5511d4c2f821c1c05ecb44b493eec185c0eec13b1dcd03d36e1a779

sha256sum ~/.injectived/config/genesis.json

Configure systemd Service for injectived​

Edit the config at /etc/systemd/system/injectived.service:

[Unit]
  Description=injectived

[Service]
  WorkingDirectory=/usr/bin
  ExecStart=/bin/bash -c '/usr/bin/injectived --log-level=error start'
  Type=simple
  Restart=always
  RestartSec=5
  User=root

[Install]
  WantedBy=multi-user.target

Starting and restarting the systemd service

sudo systemctl daemon-reload
sudo systemctl restart injectived
sudo systemctl status injectived

# enable start on system boot
sudo systemctl enable injectived

# To check Logs
journalctl -u injectived -f
