Integralayer Validator Setup & Management

Network Reference

Quick Start: Install Node

# Download binary (Linux x86_64)
wget https://github.com/Integra-layer/chain-core/releases/latest/download/intgd-linux-amd64
chmod +x intgd-linux-amd64
sudo mv intgd-linux-amd64 /usr/local/bin/intgd

# Initialize node
intgd init <moniker> --chain-id integra-1  # mainnet
intgd init <moniker> --chain-id ormos-1    # testnet

# Download genesis
curl -s https://rpc.integralayer.com/genesis | jq '.result.genesis' > ~/.intgd/config/genesis.json

System Requirements

Cloud Provider Recommendations

• DigitalOcean: General Purpose 4vCPU / 16GB (~$96/mo)
• AWS: m6i.xlarge 4vCPU / 16GB (~$140/mo)
• Hetzner: CPX41 8vCPU / 16GB (~$28/mo)

Required ports: 26656 (P2P), 26657 (RPC), 8545 (EVM RPC), 1317 (REST API)

Configuration

Persistent Peers (Mainnet)

# Add to ~/.intgd/config/config.toml [p2p] section
persistent_peers = "<node-id>@165.227.118.77:26656,<node-id>@159.65.168.118:26656,<node-id>@104.131.34.167:26656"

Persistent Peers (Testnet)

persistent_peers = "<node-id>@143.198.25.105:26656,<node-id>@165.227.177.127:26656,<node-id>@167.71.173.21:26656"

Key Config Settings

# config.toml
[p2p]
laddr = "tcp://0.0.0.0:26656"
max_num_inbound_peers = 40
max_num_outbound_peers = 10

# app.toml
minimum-gas-prices = "0airl"
pruning = "default"

[json-rpc]
enable = true
address = "0.0.0.0:8545"
ws-address = "0.0.0.0:8546"

Create Validator

intgd tx staking create-validator \
  --amount=1000000000000000000airl \
  --pubkey=$(intgd tendermint show-validator) \
  --moniker="<your-moniker>" \
  --chain-id=integra-1 \
  --commission-rate="0.05" \
  --commission-max-rate="0.20" \
  --commission-max-change-rate="0.01" \
  --min-self-delegation="1" \
  --gas=auto \
  --gas-adjustment=1.5 \
  --from=validator \
  --keyring-backend=test

Systemd Service

[Service]
Type=simple
User=root
ExecStart=/usr/local/bin/intgd start --home /root/.intgd

[Install]

sudo systemctl start intgd

Common Operations

# Check node status
intgd status | jq '.sync_info.latest_block_height'

# Check validator signing
intgd query slashing signing-info $(intgd comet show-validator)

# Unjail validator
intgd tx slashing unjail --from=validator --chain-id=integra-1 --gas=auto

# Check balances
intgd query bank balances <address>

# Delegate tokens
intgd tx staking delegate <validator-address> 1000000000000000000airl \
  --from=validator --chain-id=integra-1 --gas=auto

# Export genesis (for upgrades)
intgd export --home /root/.intgd > exported_genesis.json

# Reset chain state (dangerous - keeps keys)
intgd comet unsafe-reset-all --home /root/.intgd

# View logs
journalctl -u intgd -f --no-hostname

EVM Pre-deployed Contracts

These contracts are available at standard addresses on both networks:

Troubleshooting

• AppHash mismatch: Binary version mismatch across validators. Ensure all nodes run the same intgd binary.
• Connection refused on 26657: Check laddr in config.toml and firewall rules.
• EVM RPC not responding: Ensure [json-rpc] enable = true in app.toml and port 8545 is open.
• Validator jailed: Run unjail command above. Check signing-info for missed blocks.
• Out of memory: Increase RAM or enable pruning in app.toml.
