Welcome to your comprehensive guide on how to utilize SOLL, a powerful new compiler designed specifically for generating Ethereum-flavored WebAssembly (Ewasm) files from Solidity and Yul. Whether you’re a developer looking to get started or a user ready to deploy smart contracts, this article covers all the essentials to ensure your success.
1. What is SOLL?
SOLL stands for Solidity to Ewasm Compiler, which allows developers to convert Solidity or Yul code into Ewasm bytecode that can run on Ethereum’s platforms. Our goal is not only to support these languages but also to extend support to other languages such as Rust and C++ in the future. This guide will walk you through the steps to use SOLL effectively.
2. Requirements
- Docker: Ensure you have Docker installed to easily manage your development environment.
- SOLL: You need to pull the SOLL repository from GitHub.
- Alternatively, if you prefer not to use Docker, install the following dependencies:
- llvm-10-dev
- cmake
- binaryen
- node.js
- additional tools listed in the documentation.
3. Getting Started with SOLL
Here’s a step-by-step breakdown of how to set up your environment and compile your smart contracts.
Step 1: Pulling the Docker Image
docker pull secondstatesoll
Step 2: Get the Source Code
git clone --recursive https://github.com/second-state/soll.git
cd soll
git checkout 0.1.1
Step 3: Launch the Environment
docker run -it --rm -v $(pwd)/soll:/root/soll secondstatesoll
Step 4: Build SOLL
cd ~/soll
mkdir -p build
cd build
cmake ..
make
4. Compiling Smart Contracts
Using SOLL, you can compile Solidity and Yul contracts into their corresponding Ewasm bytecode.
For Solidity Contracts
cd ~/soll
cp ~/solldocs/examples/0-0-3.sol ~/
soll 0-0-3.sol
The output bytecode will be saved as ~0-0-3.wasm
.
For Yul Contracts
cd ~/soll
cp ~/solldocs/examples/0-0-6.yul ~/
soll -lang=Yul 0-0-6.yul
Similarly, the output bytecode will be saved as ~0-0-6.wasm
.
Analogy for Understanding Compilation
Think of compiling code like baking a cake. You start with raw ingredients (your Solidity or Yul code), and you need the right tools and environment (Docker, libraries) to combine them properly. When you mix everything together (compile your code), you set it in the oven (your compiler), and after a certain amount of time, you get a beautifully baked cake (Ewasm bytecode) ready to serve! However, if you skip any steps or use the wrong measurements, your cake may not rise properly—or in our case, the code might fail to compile or work correctly.
5. Troubleshooting
If you encounter issues during your setup or compilation, consider the following troubleshooting steps:
- Ensure Docker is running properly and is up to date.
- Verify that all dependencies are correctly installed if not using Docker.
- Re-check your command syntax for any typos.
- Make sure you’re using compatible versions of LLVM, CMake, and other tools.

6. Deploying Your Contract
Once your Ewasm bytecode is ready, you’ll need to deploy it on the Ewasm DevChain. You can do this using the provided JavaScript commands in the console. Ensure to set the deployment parameters correctly and monitor the deployment status.
