Running local node

For the purpose of this tutorial, you need to have a running blockchain node. You can either run a node locally or use any public node.

Examples of public nodes that you can experiment with are:

  • wss://acala-rpc.dwellir.com
  • wss://rpc.astar.network
  • wss://spiritnet.kilt.io

However, for better understanding, I will run a blockchain from a template locally.

Run a blockchain node locally.​

Clone the template repository:

git clone https://github.com/substrate-developer-hub/substrate-node-template.git

Go to the template directory:

cd substrate-node-template

Build​

Use the following command to build the node without launching it:

cargo build --release

Note: Depending on your operating system and Rust version, there might be additional packages required to compile this template. Check the installation instructions for your platform for the most common dependencies. Alternatively, you can use one of the alternative installation options.

Single-Node Development Chain​

The following command starts a single-node development chain that doesn't persist state:

./target/release/node-template --dev

The node is reachable via the following RPC endpoints:
