Setup

Building components

# Clone the repo.

git clone git@github.com:uqbar-dao/uqbar.git

# Configure dependency retrieval from GitHub
mkdir .cargo
echo "net.git-fetch-with-cli = true" > .cargo/config

# Get some stuff so we can build wasm.

cd uqbar
cargo install wasm-tools
rustup install nightly
rustup target add wasm32-wasi
rustup target add wasm32-wasi --toolchain nightly
cargo install cargo-wasi

# Build the runtime, along with a number of booted-at-startup WASM modules including terminal and key_value
# OPTIONAL: --release flag

cargo +nightly build --release

Boot

Get an eth-sepolia-rpc API key and pass that as an argument. You can get one for free at alchemy.com.

Make sure not to use the same home directory for two nodes at once! You can use any name for the home directory: here we just use home.

cargo +nightly run --release home --rpc wss://eth-sepolia.g.alchemy.com/v2/<your-api-key>

On boot you will be prompted to navigate to localhost:8080. Make sure your ETH wallet is connected to the Sepolia test network. Login should be straightforward, just submit the transactions and follow the flow. If you want to register a new ID you will either need Sepolia testnet tokens or an invite code.

!message our main:app_store:uqbar {"Download": {"package": {"package_name": "<pkg>", "publisher_node": "<node>"}, "install_from": "<node>"}}
!message our main:app_store:uqbar {"Install": {"package_name": "<pkg>", "publisher_node": "<node>"}}
