Run A RPC Node
Run From Source

Using source

Once the development environment is set up, build the node template. This command will build the Wasm (opens in a new tab) and native (opens in a new tab) code:

Setup eviroment for build selendra

Install the necessary dependencies for compiling and running the Selendra node software.

For Debian

sudo apt update
sudo apt install make clang pkg-config libssl-dev build-essential

For ArchLinux

sudo pacman -Syu
sudo pacman -Syu --needed --noconfirm cmake gcc openssl-1.0 pkgconf git clang
export OPENSSL_LIB_DIR="/usr/lib/openssl-1.0"
export OPENSSL_INCLUDE_DIR="/usr/include/openssl-1.0"

For MacOs

brew install cmake pkg-config openssl git llvm

Install Rust:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Initialize your Wasm Build environment:


Build Wasm and native code:

cargo build --release

Single Node Development Chain

Purge any existing dev chain state:

./target/release/selendra purge-chain --dev

Start a dev chain:

./target/release/selendra --dev

Run Alice and Bob Start Blockchain

We'll start Alice's substrate node first on default TCP port 30333 with her chain database stored locally at /tmp/alice. The bootnode ID of her node is QmRpheLN4JWdAnY7HGJfWFNbfkQCb6tFf4vvA6hgjMZKrR, which is generated from the --node-key value that we specify below:

Purge any existing Alice chain state:

./target/release/selendra purge-chain --base-path /tmp/alice --chain local

Start Alice node

./target/release/selendra \
--base-path /tmp/alice \
--chain local \
--alice \
--port 30333 \
--ws-port 9944 \
--rpc-port 9933 \
--node-key 0000000000000000000000000000000000000000000000000000000000000001 \
--telemetry-url 'wss://telemetry.polkadot.io/submit/ 0' \

In the second terminal, we'll start Bob's substrate node on a different TCP port of 30334, and with his chain database stored locally at /tmp/bob. We'll specify a value for the --bootnodes option that will connect his node to Alice's bootnode ID on TCP port 30333:

Purge any existing Bob chain state:

./target/release/selendra purge-chain --base-path /tmp/bob --chain local

Start Bob node

./target/release/selendra \
--base-path /tmp/bob \
--chain local \
--bob \
--port 30334 \
--ws-port 9945 \
--rpc-port 9934 \
--telemetry-url 'wss://telemetry.polkadot.io/submit/ 0' \
--validator \
--bootnodes /ip4/
