cd $HOME
rm -rf $HOME/tacchain
git clone https://github.com/TacBuild/tacchain.git
cd tacchain
git checkout v0.0.11
make build

✅ Setup Cosmovisor

mkdir -p $HOME/.tacchaind/cosmovisor/genesis/bin
cp build/tacchaind $HOME/.tacchaind/cosmovisor/genesis/bin/

✅ Create Systemd Service for tacchaind

sudo tee /etc/systemd/system/tacchaind.service > /dev/null <<EOF
[Unit]
Description=TacChain Node
After=network-online.target

[Service]
User=$USER
ExecStart=$(which cosmovisor) run start
Restart=always
RestartSec=5
LimitNOFILE=65535
Environment="DAEMON_HOME=$HOME/.tacchaind"
Environment="DAEMON_NAME=tacchaind"

Environment="PATH=$HOME/.tacchaind/cosmovisor/current/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin"

[Install]
WantedBy=multi-user.target
EOF

sudo systemctl daemon-reload
sudo systemctl enable tacchaind

✅ Update Port Configurations

echo 'export TAC_PORT="59"' >> ~/.bash_profile
source ~/.bash_profile

✅ Initialize Node and Set Port ( Chande node-name with yours )

tacchaind init node-name --chain-id tacchain_2391-1

✅ Genesis & Addrbook

curl -Ls https://raw.githubusercontent.com/TacBuild/tacchain/refs/heads/main/networks/tacchain_2391-1/genesis.json > $HOME/.tacchaind/config/genesis.json

✅ Seed and Peer Configurations

SEEDS=""
PEERS="9c32b3b959a2427bd2aa064f8c9a8efebdad4c23@206.217.210.164:45130,04a2152eed9f73dc44779387a870ea6480c41fe7@206.217.210.164:45140,5aaaf8140262d7416ac53abe4e0bd13b0f582168@23.92.177.41:45110,ddb3e8b8f4d051e914686302dafc2a73adf9b0d2@23.92.177.41:45120"

sed -i -e "/^\[p2p\]/,/^\[/{s/^[[:space:]]*seeds *=.*/seeds = \"$SEEDS\"/}" \
       -e "/^\[p2p\]/,/^\[/{s/^[[:space:]]*persistent_peers *=.*/persistent_peers = \"$PEERS\"/}" $HOME/.tacchaind/config/config.toml

✅ Pruning and Timeout Configurations

sed -i \
  -e 's|^pruning *=.*|pruning = "custom"|' \
  -e 's|^pruning-keep-recent *=.*|pruning-keep-recent = "100"|' \
  -e 's|^pruning-keep-every *=.*|pruning-keep-every = "0"|' \

  $HOME/.tacchaind/config/app.toml

sudo sed -i 's/timeout_commit = "5s"/timeout_commit = "2s"/' $HOME/.tacchaind/config/config.toml

✅ Port Configurations

sed -i.bak -e "s%:1317%:${TAC_PORT}317%g;
s%:8080%:${TAC_PORT}080%g;
s%:9090%:${TAC_PORT}090%g;
s%:9091%:${TAC_PORT}091%g;
s%:8545%:${TAC_PORT}545%g;
s%:8546%:${TAC_PORT}546%g;
s%:6065%:${TAC_PORT}065%g" $HOME/.tacchaind/config/app.toml

sed -i.bak -e "s%:26658%:${TAC_PORT}658%g;

s%^external_address = \"\"%external_address = \"$(wget -qO- eth0.me):${TAC_PORT}656\"%;
s%:26660%:${TAC_PORT}660%g" $HOME/.tacchaind/config/config.toml

✅ Snapshot

curl -o - -L https://snapshot.corenodehq.xyz/tac_testnet/tac_snap.tar.lz4  | lz4 -c -d - | tar -x -C $HOME/.tacchaind

✅ Start the Node

sudo systemctl start tacchaind && sudo journalctl -u tacchaind -f --no-hostname -o cat

✅ Create a new wallet (or import)

Create a new wallet:

tacchaind keys add wallet-name

Or to import an existing wallet:

tacchaind keys add wallet-name --recover

⚠️ Don't forget to backup mnemonic words!

✅ To Learn Ethereum Address

echo "0x$(tacchaind debug addr $(tacchaind keys show wallet-name -a) | grep hex | awk '{print $3}')"

This command will give you an address in the format 0x... We will request a token from the faucet with this address.

Faucet

https://spb.faucet.tac.build/

✅ Command to get public key

tacchaind tendermint show-validator

This command will give you something like this in the output (Example)

{"@type":"/cosmos.crypto.ed25519.PubKey","key":"oWg2ISpLF405Jcm2vXV+2v4fnjodh6aafuIdeoW+rUw="}

nano validatortx.json

✅ Let's paste the template below into the opened file and edit the necessary places.

{
  "pubkey": {
    "@type": "/cosmos.crypto.ed25519.PubKey",
    "key": "HERE IS THE KEY YOU GOT USING tacchaind_tendermint_show-validator"
  },
  "amount": "1000000utac",
  "moniker": "validator-name",
  "identity": "keybase_id",
  "website": "https://yourwebsite.com",
  "security": "email@domain.com",
  "details": "details",
  "commission-rate": "0.1",
  "commission-max-rate": "0.2",
  "commission-max-change-rate": "0.01",
  "min-self-delegation": "1"
}

Let's save and exit with CTRL X Y enter

✅ If everything is ready and synced, let's create our validator.

tacchain# tacchaind tx staking create-validator validatortx.json \
  --from wallet-name \
  --chain-id tacchain_2391-1 \
  --node http://localhost:59657 \
  --gas auto --gas-adjustment 1.4 --fees 9503625000000000utac -y

✅ To delegate to ourselves:

tacchaind tx staking delegate tacvaloperadress 9000000000000000000utac \
  --from wallet-name \
  --chain-id tacchain_2391-1 \
  --node http://localhost:59657 \
  --gas auto --gas-adjustment 1.4 --fees 6130825000000000utac -y
