Welcome to the world of Scilla, an innovative smart contract intermediate-level language specifically designed for the Zilliqa blockchain. Whether you’re a seasoned developer or just dipping your toes into blockchain programming, this guide will walk you through the essential steps to get started with Scilla, troubleshoot common issues, and leverage this powerful language for your projects.

What is Scilla?

Scilla, short for Smart Contract Intermediate-Level Language, is structured to enhance the safety and security of smart contracts. By eliminating vulnerabilities at the language level, Scilla promotes the development of secure applications and facilitates formal verification. The underlying platform, Zilliqa, employs sharding to provide scalability and runs on the intrinsic token, ZIL.

Your Roadmap to Building and Running Scilla

Step 1: Cloning the Source Code

To get started, you can clone Scilla’s latest release:

git clone --jobs 4 --recurse-submodules https://github.com/Zilliqa/scilla

Step 2: Building Prerequisites

Follow the platform-specific instructions for setting up your system by checking INSTALL.md.

Step 3: Compiling Scilla

To compile your Scilla project, you can execute the command:

make

Installing Scilla with opam

If you’d prefer not to build Scilla from source, you can use OCaml’s package manager, opam. Here’s how:

1. Install from GitHub

opam pin add scilla git+https://github.com/Zilliqa/scilla#master --yes

2. Install from Local Repository

Navigate to your Scilla repo and ensure you’re on the correct branch:

cd scilla-repo
git checkout master
opam install .scilla.opam

3. Running the Binary

Once built, you can evaluate a closed expression:

eval-runner -gaslimit 10000 -libdir src/stdlib tests/eval/goodlet.scilla

Troubleshooting Common Issues

If you encounter issues while working with Scilla, here are some troubleshooting ideas:

• Check if all dependencies are installed based on your platform specifications in INSTALL.md.
• If cloning fails, ensure you have the correct permissions and network connectivity.
• For configuration problems, review paths to your Scilla standard library in the environment variable SCILLA_STDLIB_PATH.
• If you receive type errors during checking, verify your contract implementation and ensure all variables are well-defined.
