# How to Sync and Run Testnet

If you would like to test your smart contract before deploying on main net, we recommend running on Pchain testnet first.

## Download Pchain's testnet release

```
wget https://github.com/pchain-org/pchain/releases/download/v1.0.01/testnet_config.tar.gz -P ~
cd ~
tar -zxf testnet_config.tar.gz
mkdir -p ~/pchain-testnet/.pchain/child_0 ~/pchain-testnet/bin/
cp ~/testnet_config/pchain ~/pchain-testnet/bin/
cp ~/testnet_config/*.json ~/pchain-testnet/.pchain/child_0/
cd ~/pchain-testnet
./bin/pchain --datadir .pchain  init .pchain/child_0/eth_genesis.json child_0
```

## Initialize testnet child\_0

```
cd ~/pchain-testnet
./bin/pchain --datadir=.pchain --testnet --childChain=child_0
```

## Run pchain testnet

```
./bin/pchain --datadir=.pchain --testnet --rpc --rpcapi=eth,web3,admin,tdm,miner,personal,chain,txpool,del --gcmode=archive --rpcvhosts=* --rpcaddr=0.0.0.0 --childChain=child_0 > /dev/null &
```

## Attach to child\_0's console

```
./bin/pchain attach .pchain/child_0/pchain.ipc
```
