During this workshop, we will show users how to use the CasperLabs contracts crate to set up a new smart contract project, and how to leverage the test infrastructure.

Goals

• Install CasperLabs contract SDK

• Create a new smart contract project

• Set up the build environment

• Build the empty contract

• Run the test

• Open the project in your IDE and view the project structure.

• We will record the session.

Step by Step Plan

These instructions are also available on GitHub at: https://github.com/CasperLabs/CasperLabs/tree/dev/execution-engine/cargo-casperlabs

1. Install the SDK

cargo install cargo-casperlabs --force

2. Create your project & name it as you wish.

cargo casperlabs my_project

3. Set up your build environment

cd my_project/contract
rustup install $(cat rust-toolchain)
rustup target add --toolchain=$(cat rust-toolchain) wasm32-unknown-unknown

4. Now let’s build the empty project

cargo build --release

Your contract will be built to:  my_project/contract/target/wasm32-unknown-unknown/release/contract.wasm.

5. Next we can run the test that comes with the SDK. This framework will run the contract within the execution engine with the tests.

cd my_project/tests
cargo test

6. Next we can open the project inside an IDE and observe the structure of the empty contract.
