Prerequisites​

Before you start, complete the following prerequisites:

  • We recommend running public testnet nodes on machines with the following characteristics:
    • at least 8 cores
    • 32GB of RAM
    • 300GB of disk space
  • Install Go 1.22.3 or later.
  • If you wish to build the binary from the source code, install just 1.34.0 or later.

1. Install​

To be able to interact with the node, install wardend (the Warden binary) using the script below. There are two ways to do it:

Option 1: Use the prebuilt binary​

  1. Download the binary for your platform from the release page and unzip it. The archive contains the wardend binary.

  2. Navigate to the directory containing the binary and initialize the node:

    ./wardend init my-chain-moniker
    tip

    When interacting with the node, you should add the path to the binary before wardend commands.

Option 2: Use the source code​

  1. Clone the repository and navigate to the root directory:

    git clone --depth 1 --branch v0.4.2 https://github.com/warden-protocol/wardenprotocol
    cd wardenprotocol

    The binary is located in /wardenprotocol/build.

  2. Use our just script to build the wardend binary and install it to the $GOPATH/bin directory. Then initialize the node.

    just build
    just install
    wardend init my-chain-moniker

    Alternatively, you can skip installation to $GOPATH/bin:

    just build
    build/wardend init my-chain-moniker
    tip

    When interacting with the node, you should add the path to the binary before wardend commands. If you install the binary to $GOPATH/bin, it's not required.

2. Configure​

To configure wardend, do the following:

  1. Prepare the genesis file:

    cd $HOME/.warden/config
    rm genesis.json
    wget https://buenavista-genesis.s3.eu-west-1.amazonaws.com/genesis.json.tar.xz | tar -xJ

  2. Set the mandatory configuration options: the minimum gas price and persistent peers.

    sed -i 's/minimum-gas-prices = ""/minimum-gas-prices = "250uward"/' app.toml
    sed -i 's/persistent_peers = ""/persistent_peers = "loading..."/' config.toml

3. Set up the state sync​

tip

This step is recommended but optional.

To speed up the initial sync, you can use the state sync feature. This will allow you to download the state at a specific height from a trusted node and after that only download the blocks from the network.

You'll need to use a trusted RPC endpoint – for example, the following:

https://rpc.buenavista.wardenprotocol.org

  1. From this RPC endpoint, you can get the trusted block height and hash:

    export SNAP_RPC_SERVERS="https://rpc.buenavista.wardenprotocol.org:443,https://rpc.buenavista.wardenprotocol.org:443    "
    export LATEST_HEIGHT=$(curl -s "https://rpc.buenavista.wardenprotocol.org/block" | jq -r .result.block.header.height)
    export BLOCK_HEIGHT=$((LATEST_HEIGHT - 2000))
    export TRUST_HASH=$(curl -s "https://rpc.buenavista.wardenprotocol.org/block?height=$BLOCK_HEIGHT" | jq -r .result.block_id.hash)

  2. Check that all variables have been set correctly:

    echo $LATEST_HEIGHT $BLOCK_HEIGHT $TRUST_HASH

    The output should be similar to this:

    70694 68694 6AF4938885598EA10C0BD493D267EF363B067101B6F81D1210B27EBE0B32FA2A

  3. Add the state sync configuration to your config.toml:

    sed -i.bak -E "s|^(enable[[:space:]]+=[[:space:]]+).*$|\1true| ; \
    s|^(rpc_servers[[:space:]]+=[[:space:]]+).*$|\1\"$SNAP_RPC_SERVERS\"| ; \
    s|^(trust_height[[:space:]]+=[[:space:]]+).*$|\1$BLOCK_HEIGHT| ; \
    s|^(trust_hash[[:space:]]+=[[:space:]]+).*$|\1\"$TRUST_HASH\"|" $HOME/.warden/config/config.toml

4. Start the node​

Now you can start the node using the following command:

wardend start

If needed, add the path to the binary before the command:

path-to-binary/wardend start

It'll connect to persistent peers provided and start downloading blocks. You can check the logs to see the progress.

Next steps​

If you want to create a validator in the testnet, follow the instructions in the Create a validator section.
