agoric node setup for devnet — agoricdev-11

Official documentation:

Validator Guide for Devnet

Explorer:

https://devnet.explorer.agoric.net/

Usefull tools and references

To set up monitoring for your validator node navigate to Set up monitoring and alerting for agoric validator

To migrate your validator to another machine read Migrate your validator to another machine

Set up your agoric fullnode

Option 1 (automatic)

You can setup your agoric fullnode in few minutes by using automated script below. It will prompt you to input your validator node name!

wget -O agoric_devnet.sh https://raw.githubusercontent.com/kj89/testnet_manuals/main/agoric/agoric_devnet.sh && chmod +x agoric_devnet.sh && ./agoric_devnet.sh

Option 2 (manual)

You can follow manual guide if you better prefer setting up node manually

Post installation

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

agd status 2>&1 | jq .SyncInfo

Create wallet

To create new wallet you can use command below. Don’t forget to save the mnemonic

agd keys add $WALLET

(OPTIONAL) To recover your wallet using seed phrase

agd keys add $WALLET --recover

To get current list of wallets

agd keys list

Save wallet info

Add wallet address

WALLET_ADDRESS=$(agd keys show $WALLET -a)

Add valoper address

VALOPER_ADDRESS=$(agd keys show $WALLET --bech val -a)

Load variables into system

echo 'export WALLET_ADDRESS='${WALLET_ADDRESS} >> $HOME/.bash_profile
echo 'export VALOPER_ADDRESS='${VALOPER_ADDRESS} >> $HOME/.bash_profile
source $HOME/.bash_profile

Top up your wallet balance using faucet

To get free tokens in agoricdev-11 testnet:

  • navigate to Agoric official discord
  • open #faucet channel under DEVELOPMENT category
  • input command: !faucet client <WALLET_ADDRESS>

Create validator

Before creating validator please make sure that you have at least 1 bld (1 bld is equal to 1000000 ubld) and your node is synchronized

To check your wallet balance:

agd query bank balances $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

agd tx staking create-validator \
  --amount 1000000ubld \
  --from $WALLET \
  --commission-max-change-rate "0.01" \
  --commission-max-rate "0.2" \
  --commission-rate "0.07" \
  --min-self-delegation "1" \
  --pubkey  $(agd show-validator) \
  --moniker $NODENAME \
  --chain-id $CHAIN_ID

Security

To protect you keys please make sure you follow basic security rules

Set up ssh keys for authentication

Good tutorial on how to set up ssh keys for authentication to your server can be found here

Basic Firewall security

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 26656,26660,26657,1317/tcp
sudo ufw enable

Monitoring

To monitor and get alerted about your validator health status you can use my guide on Set up monitoring and alerting for agoric validator

Calculate synchronization time

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/agoric/tools/synctime.py && python3 ./synctime.py

Get currently connected peer list with ids

curl -sS http://localhost:26657/net_info | jq -r '.result.peers[] | "\(.node_info.id)@\(.remote_ip):\(.node_info.listen_addr)"' | awk -F ':' '{print $1":"$(NF)}'

Usefull commands

Service management

Check logs

journalctl -fu agd -o cat

Start service

systemctl start agd

Stop service

systemctl stop agd

Restart service

systemctl restart agd

Node info

Synchronization info

agd status 2>&1 | jq .SyncInfo

Show node id

agd show-node-id

Wallet operations

List of wallets

agd keys list

Recover wallet

agd keys add $WALLET --recover

Delete wallet

Get wallet balance

agd query bank balances $WALLET_ADDRESS

Transfer funds

Voting

agd tx gov vote 1 yes --from $WALLET --chain-id=$CHAIN_ID

Staking, Delegation and Rewards

Delegate stake

agd tx staking delegate $VALOPER_ADDRESS 10000000ubld --from=$WALLET --chain-id=$CHAIN_ID --gas=auto

Redelegate stake from validator to another validator

agd tx staking redelegate <srcValidatorAddress> <destValidatorAddress> 10000000ubld --from=$WALLET --chain-id=$CHAIN_ID --gas=auto

Withdraw all rewards

agd tx distribution withdraw-all-rewards --from=$WALLET --chain-id=$CHAIN_ID --gas=auto

Withdraw rewards with commision

agd tx distribution withdraw-rewards $VALOPER_ADDRESS --from=$WALLET --commission --chain-id=$CHAIN_ID

Validator management

Edit validator

agd tx staking edit-validator \
--moniker=$NODENAME \
--identity=<your_keybase_id> \
--website="<your_website>" \
--details="<your_validator_description>" \
--chain-id=$CHAIN_ID \
--from=$WALLET

Unjail validator

agd tx slashing unjail \
  --broadcast-mode=block \
  --from=$WALLET \
  --chain-id=$CHAIN_ID \
  --gas=auto

This commands will completely remove node from server. Use at your own risk!

systemctl stop agd
systemctl disable agd
rm /etc/systemd/system/agd.service -rf
rm $(which agd) -rf
rm $HOME/.agoric* -rf
rm $HOME/agoric-sdk -rf
