cd xrp
git checkout v6.0.0
make install
```

#### Configure Node

### Initialize Node

Please replace YOUR\_MONIKER with your own moniker.

```
exrpd init TechHubs --chain-id xrplevm_1449000-1
exrpd config set client chain-id xrplevm_1449000-1
exrpd config set client keyring-backend os
```

### Install WASMVM

```
export WASMVM_VERSION=v2.1.2
export LD_LIBRARY_PATH=$HOME/.exrpd/lib
mkdir -p $LD_LIBRARY_PATH
wget "https://github.com/CosmWasm/wasmvm/releases/download/$WASMVM_VERSION/libwasmvm.$(uname -m).so" -O "$LD_LIBRARY_PATH/libwasmvm.$(uname -m).so"
echo "export LD_LIBRARY_PATH=$HOME/.exrpd/lib:$LD_LIBRARY_PATH" >> ~/.bashrc
source ~/.bashrc
```

### Config port, pruning, minimum gas price, enable prometheus and disable indexing

```
echo "export XRPL_PORT="47"" >> $HOME/.bashrc
source $HOME/.bashrc
