Installation & Setup Steps

Environment Setup

System Preparation

1. Update and Upgrade System

sudo apt update && sudo apt upgrade -y

2. Install Essential Packages

sudo apt install make gcc git jq chrony curl lz4 wget tar build-essential -y

3. Synchronize System Time

sudo timedatectl set-timezone UTC
sudo systemctl enable --now chronyd
timedatectl

Install Go

Suggested Version: Go 1.24.x (required for seid v6.3+)

Installation Steps

# Check for existing Go installation
go version

# Download and install Go 1.24.x
wget https://go.dev/dl/go1.24.5.linux-amd64.tar.gz
sudo tar -C /usr/local -xzf go1.24.5.linux-amd64.tar.gz

# Add Go to your environment variables
echo 'export PATH=$PATH:/usr/local/go/bin' >> $HOME/.bashrc
source $HOME/.bashrc

# Verify installation
go version

Install Sei

Install Sei Binary

# Clone repository and install
git clone https://github.com/sei-protocol/sei-chain.git
cd sei-chain
git checkout <version-tag>  # Replace with specific version
make install

# Verify installation
seid version

See Network Versions table above for current recommended version.

Alternative: Docker Image

Official Docker images are available at GitHub Container Registry.

# Pull the latest version
docker pull ghcr.io/sei-protocol/sei:latest

# Or pull a specific version (recommended)
docker pull ghcr.io/sei-protocol/sei:v6.3.1

Available architectures: linux/amd64 and linux/arm64.

If you encounter an error like command not found: seid, you may need to set your GOPATH environment variable.Add the following to your ~/.bashrc or ~/.zshrc:

export GOPATH=$(go env GOPATH)
export PATH=$PATH:$GOPATH/bin

Then reload your shell with source ~/.bashrc or source ~/.zshrc.For more information see here.

Initialize Chain Files

Default init mode is full (RPC/P2P bind to all interfaces). For validator or seed nodes, use --mode validator or --mode seed so RPC and P2P bind to localhost only. See the Validator Operations Guide for the full validator init example.

Peers can be found here -

mainnet (pacific-1):

testnet (atlantic-2):

# Initialize node (default mode is full: RPC/P2P bind to all interfaces)
# For validator nodes, use: seid init <your-moniker> --chain-id <chain-id> --mode validator
seid init <your-moniker> --chain-id <chain-id>

# Genesis is written automatically for known networks (mainnet and testnets); no download needed.

# Configure peers in config.toml.
PEERS="<comma-separated-peer-list>"

#Set persistent peers in config.toml
sed -i 's/persistent-peers = .*/persistent-peers = "'$PEERS'"/' ~/.sei/config/config.toml

Configure App Settings

# Set minimum gas price (recommended; helps prevent spam transactions)
# Mainnet enforces a chain-wide minimum of 0.02usei, so set at least that value
# Use "0usei" only for local development or private networks
sed -i -e "s/^minimum-gas-prices *=.*/minimum-gas-prices = \"0.02usei\"/" $HOME/.sei/config/app.toml

# Tune mempool settings
sed -i \
  -e 's/^keep-invalid-txs-in-cache = .*/keep-invalid-txs-in-cache = true/' \
  -e 's/^ttl-duration = .*/ttl-duration = "5s"/' \
  -e 's/^ttl-num-blocks = .*/ttl-num-blocks = 5/' \
  $HOME/.sei/config/config.toml

# Set Concurrent Workers to 500 and enable occ
sed -i -e "s/^#concurrency-workers *=.*/concurrency-workers = 500/" $HOME/.sei/config/app.toml
sed -i -e "s/^occ-enabled *=.*/occ-enabled = true/" $HOME/.sei/config/app.toml

In case of running an Archive Node, make sure to set your state-store settings to ss-keep-recent = 0 with

sed -i 's/^ss-keep-recent = [0-9]*/ss-keep-recent = 0/' ~/.sei/config/app.toml

Advanced Configuration

Archive Node Setup

An archive node maintains the complete historical record of the chain. This requires disabling state sync and starting with a pre-existing database using a “snapshot”.1. Disable State Sync — In $HOME/.sei/config/config.toml , modify the [statesync] section:

# State sync configuration
[statesync]
enable = false

2. Configure Archive Node Peers — To sync from the height your snapshot was created at, you need peers retaining a large amount of historical blocks. The node will require specific peers during initial sync, which can be changed at a later time.

Mempool Configuration

For optimal transaction handling and resource management, it is recommended to update the mempool settings in your config.toml file.

Adjust these parameters if you encounter performance or resource issues on your specific hardware.

# Mempool configuration settings
[mempool]

# Broadcast transactions to other nodes
broadcast = true

# Maximum number of transactions in the mempool
size = 5000

# Limit the total size of all txs in the mempool.
max-txs-bytes = 10737418240

# Size of the cache (used to filter duplicate transactions)
cache-size = 10000

# Do not remove invalid transactions from the cache
keep-invalid-txs-in-cache = true

# Maximum size of a single transaction
max-tx-bytes = 2048576

# Maximum size of a batch of transactions to send to a peer
max-batch-bytes = 0

# Maximum length of time a transaction can remain in the mempool
ttl-duration = "3s"

# Maximum number of blocks a transaction can remain in the mempool
ttl-num-blocks = 5

tx-notify-threshold = 0

check-tx-error-blacklist-enabled = true

check-tx-error-threshold = 50

pending-size = 5000

max-pending-txs-bytes = 1073741824

pending-ttl-duration = "3s"

pending-ttl-num-blocks = 5

Run Node

Setting Up a systemd Service

If you see an error such as panic: recovered: runtime error: integer divide by zero it means you can’t start nodes straight from the genesis file. Instead, sync to the block tip via state sync or using a snapshot.

For production deployments, configure a systemd service to ensure your node restarts automatically:

# Create the systemd service file
sudo tee /etc/systemd/system/seid.service > /dev/null << EOF
[Unit]
Description=Sei Node
After=network-online.target

[Service]
User=$USER
ExecStart=$(which seid) start
Restart=always
RestartSec=3
LimitNOFILE=65535

[Install]
WantedBy=multi-user.target
EOF

# Reload systemd, enable and start the service
sudo systemctl daemon-reload
sudo systemctl enable seid
sudo systemctl start seid

Monitoring & Troubleshooting

Check your node’s status with these commands:

# Check sync status
seid status

# Monitor logs in real-time
journalctl -u seid -f -o cat

# Check validator status (if running a validator)
seid query staking validator $(seid keys show <your_key> --bech val -a)

Common Issues & Solutions

Sync Issues

Verify sufficient disk space
Ensure stable network connectivity
Confirm system time is synchronized
Consider using state sync for initial setup

Performance Problems

Monitor system resources (CPU, RAM, I/O)
Evaluate disk performance and network bandwidth
Adjust mempool and peer settings if needed
