Smart Contracts & Junod Development
Installation
The short version is that you will need rust and
junod available.Rust
Assuming you have never worked with rust, you will first need to install some tooling. The standard approach is to use
rustup to maintain dependencies and handle updating multiple versions of cargo and rustc, which you will be using.Installing Rust in Linux and Mac
1
rustup default stable

Using Juno Testnets
A Juno testnet https://github.com/CosmosContracts/Juno has been launched to save you the hassle of running a local network and speed up your development.
That said, many users will want to run a local node. Check out this guide to get set up with a single command:
Use go 1.16.3+ for compiling
junodexecutable if you are building from source. If you already are running a validator node, it's likely junod is already accessible. If which junod shows output, then you're probably good to go.1
# clone juno repo
2
git clone https://github.com/CosmosContracts/juno.git && cd juno

4
git fetch --tags

git checkout v5.0.1

# build juno executable

make install
