Configure Moniker

MONIKER="<your-node-name>"

Install GO

sudo rm -rf /usr/local/go
curl -Ls https://go.dev/dl/go1.21.11.linux-amd64.tar.gz | sudo tar -xzf - -C /usr/local
eval $(echo 'export PATH=$PATH:/usr/local/go/bin' | sudo tee /etc/profile.d/golang.sh)
eval $(echo 'export PATH=$PATH:$HOME/go/bin' | tee -a $HOME/.profile)

Download and Build Binaries

# Clone project repository
cd $HOME
rm -rf symphony
git clone https://github.com/Orchestra-Labs/symphony
cd symphony
git checkout v0.3.0

# Build binaries
make build

# Prepare binaries for Cosmovisor
mkdir -p $HOME/.symphonyd/cosmovisor/genesis/bin
mv build/symphonyd $HOME/.symphonyd/cosmovisor/genesis/bin/
rm -rf build

# Create application symlinks
sudo ln -s $HOME/.symphonyd/cosmovisor/genesis $HOME/.symphonyd/cosmovisor/current -f
sudo ln -s $HOME/.symphonyd/cosmovisor/current/bin/symphonyd /usr/local/bin/symphonyd -f

Install Cosmovisor and create daemon service

# Download and install Cosmovisor
go install cosmossdk.io/tools/cosmovisor/cmd/[email protected]

# Create service

Initialize the node

# Set node configuration
symphonyd config chain-id symphony-testnet-3
symphonyd config keyring-backend test

# Initialize the node
symphonyd init $MONIKER --chain-id symphony-testnet-3

# Download genesis and addrbook
curl -Ls https://snapshot.ravenode.xyz/symphony/genesis.json > $HOME/.symphonyd/config/genesis.json

Download Latest Snapshot & extract the file

curl -L https://snapshot.ravenode.xyz/symphony/symphony-latest.tar.lz4 | tar -Ilz4 -xf - -C $HOME/.symphonyd
[[ -f $HOME/.symphonyd/data/upgrade-info.json ]] && cp $HOME/.symphonyd/data/upgrade-info.json $HOME/.symphonyd/cosmovisor/genesis/upgrade-info.json

Start Service & Check Node Logs

sudo systemctl restart symphony.service && sudo journalctl -u symphony.service -f --no-hostname -o cat

Verify node's block height sync

while true; do
  local_height=$(symphonyd status 2>&1 | jq -r .SyncInfo.latest_block_height || echo "0")

  network_height=$(curl -s https://rpc.symphony.ravenode.xyz/status | jq -r .result.sync_info.latest_block_height || echo "0")

  blocks_left=$((network_height - local_height))

  n_peers=$(curl -Ss localhost:26657/net_info | jq -r .result.n_peers || echo "0")

  echo "Curr block: $local_height (blocks left: $blocks_left) | Peers: $n_peers"

  sleep 3
done

Example Output

Curr block: 194935 (blocks left: 1) | Peers: 47
Curr block: 194936 (blocks left: 0) | Peers: 47
Curr block: 194937 (blocks left: 0) | Peers: 47

If you receive output like the above and "blocks left" is 0, it means the node is fully synced and has reached the latest block height. The node is now up to date with the blockchain and in sync with the other peers.

Spin Up Validator

1. Create a wallet

You have two options for that.

OPTION 1 - CREATE NEW WALLET

symphonyd keys add wallet

Save the mnemonic output as this is the only way to recover your validator wallet in case you lose it!

OPTION 2 - RECOVER EXISTING WALLET

symphonyd keys add wallet --recover

To list your wallets use command below

symphonyd keys list

2. Fund a wallet

To create a validator, you need to fund the previously created wallet using https://testnet.ping.pub/symphony/faucet

To check wallet balance use command below

symphonyd q bank balances $(symphonyd keys show wallet -a)

3. Create Validator

Please make sure you have adjusted moniker, identity, details, website to match your values.

symphonyd tx staking create-validator \
--amount 10000note \
--pubkey $(symphonyd tendermint show-validator) \
--moniker "your-moniker-name" \
--identity "your-keybase-id" \
--details "your-details" \
--website "your-website" \
--security-contact "your-email" \
--chain-id symphony-testnet-3 \
--commission-rate 0.05 \
--commission-max-rate 0.20 \
--commission-max-change-rate 0.01 \
--min-self-delegation 1 \
--from wallet \
--gas-adjustment 1.4 \
--gas auto \
--fees 800note \
-y

Save the ~/.symphonyd/config/priv_validator_key.json file as this is the only way to recover your validator signing key in case you lose it!

Fill Validator Form

nce your node is synced and you've successfully created a validator, please fill out this form to receive additional faucet tokens for validator bonding: https://forms.gle/98ajH8wXCowVnGZi6

Join Symphony Discord and receive Validator role, submit your validator link and tag the team.
