Like any Cosmos-SDK chain, the hardware requirements are pretty modest.
- 3x CPUs; the faster clock speed the better
- 4GB RAM
- 80GB Disk
- Permanent Internet connection (traffic will be minimal during testnet; 10Mbps will be plenty - for production at least 100Mbps is expected)
- 4x CPUs; the faster clock speed the better
- 8GB RAM
- 200GB of storage (SSD or NVME)
- Permanent Internet connection (traffic will be minimal during testnet; 10Mbps will be plenty - for production at least 100Mbps is expected)
You can setup your sei fullnode in few minutes by using automated script below. It will prompt you to input your validator node name!
wget -O sei.sh https://raw.githubusercontent.com/kj89/testnet_manuals/main/sei/sei.sh && chmod +x sei.sh && ./sei.sh
You can follow manual guide if you better prefer setting up node manually
When installation is finished please load variables into system
source $HOME/.bash_profile
Next you have to make sure your validator is syncing blocks. You can use command below to check synchronization status
seid status 2>&1 | jq .SyncInfo
sudo apt update
sudo apt install lz4 -y
sudo systemctl stop seid
seid tendermint unsafe-reset-all --home $HOME/.sei --keep-addr-book
cd $HOME/.sei
rm -rf data
SNAP_NAME=$(curl -s https://snapshots1-testnet.nodejumper.io/sei-testnet/ | egrep -o ">atlantic-1.*\.tar.lz4" | tr -d ">")
curl https://snapshots1-testnet.nodejumper.io/sei-testnet/${SNAP_NAME} | lz4 -dc - | tar -xf -
sudo systemctl restart seid
sudo journalctl -u seid -f --no-hostname -o cat
To create new wallet you can use command below. Don’t forget to save the mnemonic
seid keys add $WALLET
(OPTIONAL) To recover your wallet using seed phrase
seid keys add $WALLET --recover
To get current list of wallets
seid keys list
Add wallet and valoper address and load variables into the system
SEI_WALLET_ADDRESS=$(seid keys show $WALLET -a)
SEI_VALOPER_ADDRESS=$(seid keys show $WALLET --bech val -a)
echo 'export SEI_WALLET_ADDRESS='${SEI_WALLET_ADDRESS} >> $HOME/.bash_profile
echo 'export SEI_VALOPER_ADDRESS='${SEI_VALOPER_ADDRESS} >> $HOME/.bash_profile
source $HOME/.bash_profile
To top up your wallet join Sei discord server and navigate to #atlantic-1-faucet channel
To request a faucet grant:
!faucet <YOUR_WALLET_ADDRESS>
Before creating validator please make sure that you have at least 1 sei (1 sei is equal to 1000000 usei) and your node is synchronized
To check your wallet balance:
seid query bank balances $SEI_WALLET_ADDRESS
If your wallet does not show any balance than probably your node is still syncing. Please wait until it finish to synchronize and then continue
To create your validator run command below
seid tx staking create-validator \
--amount 1000000usei \
--from $WALLET \
--commission-max-change-rate "0.01" \
--commission-max-rate "0.2" \
--commission-rate "0.07" \
--min-self-delegation "1" \
--pubkey $(seid tendermint show-validator) \
--moniker $NODENAME \
--chain-id $SEI_CHAIN_ID
To protect you keys please make sure you follow basic security rules
Good tutorial on how to set up ssh keys for authentication to your server can be found here
Start by checking the status of ufw.
sudo ufw status
Sets the default to allow outgoing connections, deny all incoming except ssh and 26656. Limit SSH login attempts
sudo ufw default allow outgoing
sudo ufw default deny incoming
sudo ufw allow ssh/tcp
sudo ufw limit ssh/tcp
sudo ufw allow ${SEI_PORT}656,${SEI_PORT}660/tcp
sudo ufw enable
To monitor and get alerted about your validator health status you can use my guide on Set up monitoring and alerting for sei validator
This script will help you to estimate how much time it will take to fully synchronize your node
It measures average blocks per minute that are being synchronized for period of 5 minutes and then gives you results
wget -O synctime.py https://raw.githubusercontent.com/kj89/testnet_manuals/main/sei/tools/synctime.py && python3 ./synctime.py
