Installation

Manual node setup

If you want to setup Selfchain fullnode manually follow the steps below

Update and upgrade

sudo apt update -y
sudo apt-get install -y git jq lz4 build-essential make gcc curl 
sudo apt update -y

Install GO

if ! [ -x "$(command -v go)" ]; then
  ver="1.20.3"
  cd $HOME
  wget "https://golang.org/dl/go$ver.linux-amd64.tar.gz"
  sudo rm -rf /usr/local/go
  sudo tar -C /usr/local -xzf "go$ver.linux-amd64.tar.gz"
  rm "go$ver.linux-amd64.tar.gz"
  echo "export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin" >> ~/.bash_profile
  source ~/.bash_profile
fi

Install node

cd $HOME
wget https://storage.googleapis.com/pryzm-resources/pryzmd-v0.2.2-linux-amd64.tar.gz
tar -xzvf pryzmd-v0.2.2-linux-amd64.tar.gz
mv selfchaind /root/go/bin

Setting up vars

You should replace values in <> <YOUR_MONIKER> Here you should put name of your moniker (validator) that will be visible in explorer <YOUR_WALLET> Here you shoud put the name of your wallet

SELFCHAIN_WALLET="<YOUR_WALLET_NAME>"
SELFCHAIN_NODENAME="<YOUR_MONIKER>"
SELFCHAIN_CHAIN_ID="self-dev-1"
echo "
export SELFCHAIN_WALLET=${SELFCHAIN_WALLET}
export SELFCHAIN_NODENAME=${SELFCHAIN_NODENAME}
export SELFCHAIN_CHAIN_ID=${SELFCHAIN_CHAIN_ID}
" >> $HOME/.bash_profile

source $HOME/.bash_profile

Configure your node

selfchaind config chain-id ${SELFCHAIN_CHAIN_ID}

Initialize your node

selfchaind init ${SELFCHAIN_NODENAME} --chain-id ${SELFCHAIN_CHAIN_ID}

Download genesis & addrbook

curl -Ls "https://snapshots.l0vd.com/archway-mainnet/genesis.json" > $HOME/.selfchain/config/genesis.json
curl -Ls "https://snapshots.l0vd.com/archway-mainnet/addrbook.json" > $HOME/.selfchain/config/addrbook.json

(OPTIONAL) Set custom ports

If you want to use non-default ports

SELFCHAIN_PORT=<SET_CUSTOM_PORT> #Example: SELFCHAIN_PORT=56 (numbers from 1 to 64)
sed -i.bak -e "s%^proxy_app = \"tcp://127.0.0.1:26658\"%proxy_app = \"tcp://127.0.0.1:${SELFCHAIN_PORT}658\"%; s%^laddr = \"tcp://127.0.0.1:26657\"%laddr = \"tcp://127.0.0.1:${SELFCHAIN_PORT}657\"%; s%^pprof_laddr = \"localhost:6060\"%pprof_laddr = \"localhost:${SELFCHAIN_PORT}060\"%; s%^laddr = \"tcp://0.0.0.0:26656\"%laddr = \"tcp://0.0.0.0:${SELFCHAIN_PORT}656\"%; s%^prometheus_listen_addr = \":26660\"%prometheus_listen_addr = \":${SELFCHAIN_PORT}660\"%" /$HOME/.selfchain/config/config.toml
sed -i.bak -e "s%^address = \"tcp://0.0.0.0:1317\"%address = \"tcp://0.0.0.0:${SELFCHAIN_PORT}317\"%; s%^address = \"tcp://localhost:1317\"%address = \"tcp://0.0.0.0:${SELFCHAIN_PORT}317\"%; s%^address = \":8080\"%address = \":${SELFCHAIN_PORT}080\"%; s%^address = \"0.0.0.0:9090\"%address = \"0.0.0.0:${SELFCHAIN_PORT}090\"%; s%^address = \"localhost:9090\"%address = \"localhost:${SELFCHAIN_PORT}090\"%; s%^address = \"0.0.0.0:9091\"%address = \"0.0.0.0:${SELFCHAIN_PORT}091\"%; s%^address = \"localhost:9091\"%address = \"localhost:${SELFCHAIN_PORT}091\"%; s%^address = \"0.0.0.0:8545\"%address = \"0.0.0.0:${SELFCHAIN_PORT}545\"%; s%^ws-address = \"0.0.0.0:8546\"%ws-address = \"0.0.0.0:${SELFCHAIN_PORT}546\"%" /$HOME/.selfchain/config/app.toml

Set seeds and peers

PEERS="@selfchain-testnet.peers.l0vd.com:"
sed -i -e "s/^seeds *=.*/seeds = \"$SEEDS\"/; s/^persistent_peers *=.*/persistent_peers = \"$PEERS\"/" $HOME/.selfchain/config/config.toml

Config pruning

pruning="custom"
pruning_keep_recent="100"
pruning_keep_every="0"
pruning_interval="50"
sed -i -e "s/^pruning *=.*/pruning = \"$pruning\"/" $HOME/.selfchain/config/app.toml
sed -i -e "s/^pruning-keep-recent *=.*/pruning-keep-recent = \"$pruning_keep_recent\"/" $HOME/.selfchain/config/app.toml
sed -i -e "s/^pruning-keep-every *=.*/pruning-keep-every = \"$pruning_keep_every\"/" $HOME/.selfchain/config/app.toml
sed -i -e "s/^pruning-interval *=.*/pruning-interval = \"$pruning_interval\"/" $HOME/.selfchain/config/app.toml

Set minimum gas price and kv indexer

sed -i -e "s/^minimum-gas-prices *=.*/minimum-gas-prices = \"0uself\"/" $HOME/.selfchain/config/app.toml
sed -i -e "s/^indexer *=.*/indexer = \"kv\"/" $HOME/.selfchain/config/config.toml

Create Service

sudo tee /etc/systemd/system/selfchaind.service > /dev/null <<EOF
[Unit]
Description=Selfchain testnet
After=network-online.target

[Service]
User=$USER
ExecStart=$(which selfchaind) start
Restart=on-failure
RestartSec=3
LimitNOFILE=65535

[Install]
WantedBy=multi-user.target
EOF

Reset blockchain info and restart your node

sudo systemctl daemon-reload
sudo systemctl enable selfchaind
selfchaind tendermint unsafe-reset-all --home $HOME/.selfchain --keep-addr-book
sudo systemctl restart selfchaind && sudo journalctl -u selfchaind -f -o cat

(OPTIONAL) Use State Sync

State Sync

Starting a validator

1. Add a new key

selfchaind keys add ${SELFCHAIN_WALLET}

(OR)

1. Recover your key

selfchaind keys add ${SELFCHAIN_WALLET} --recover
SELFCHAIN_WALLET_ADDR=$(selfchaind keys show ${SELFCHAIN_WALLET} -a)
echo "export SELFCHAIN_WALLET_ADDR=${SELFCHAIN_WALLET_ADDR}" >> $HOME/.bash_profile

source $HOME/.bash_profile

2. Create validator

Wait until the node is synchronized.

selfchaind tx staking create-validator \
--amount 1000000uself \
--commission-max-change-rate "0.01" \
--commission-max-rate "0.20" \
--commission-rate "0.1" \
--min-self-delegation "1" \
--details "" \
--pubkey $(selfchaind tendermint show-validator) \
--moniker ${SELFCHAIN_NODENAME} \
--chain-id ${SELFCHAIN_CHAIN_ID} \
--from ${SELFCHAIN_WALLET_ADDR} \
--gas-prices 0uself \
--gas-adjustment 1.2 \
--gas auto \
--yes

Set up Price-feeder

Install docker compose

Docker install guide

Get docker compose file

cd $HOME
mkdir pryzm-feeder
cd pryzm-feeder
wget https://storage.googleapis.com/pryzm-zone/feeder/docker-compose.yml

Get config and sql.init files

cd $HOME
cd pryzm-feeder
wget https://storage.googleapis.com/pryzm-zone/feeder/config.yaml
wget https://storage.googleapis.com/pryzm-zone/feeder/init.sql

Create and fund price-feeder wallet using Faucet

PRYZM_FEEDER_WALLET_NAME=<YOUR_FEEDER_WALLET_NAME>
pryzmd keys add $PRYZM_FEEDER_WALLET_NAME

Set manually these fields in config.yaml file

feeder: "<YOUR FEEDER WALLET ADDRESS>"
feederMnemonic: "<YOUR FEEDER WALLET ADDRESS SEED PHRASE>"
validator: "<YOUR VALOPER (przymvaloper...)>"
rpcUrl: "http://localhost:{YOUR_PORT}"
lcdUrl: "http://localhost:{YOUR_PORT}"
grpcWebUrl: "http://localhost:{YOUR_PORT}"
wsUrl: "ws://localhost:{YOUR_PORT}"

Delegate rights to feeder

pryzmd tx oracle delegate-feed-consent <YOUR FEEDER ADDRESS> --fees 2000factory/pryzm15k9s9p0ar0cx27nayrgk6vmhyec3lj7vkry7rx/uusdsim,3000upryzm --from <YOUR VALIDATOR WALLET ADDRESS>

Run your feeder
