Background

Ylem is a statically-typed curly-braces programming language designed for developing smart contracts that run on the Core-Coin Virtual Machine. Smart contracts are programs that are executed inside a peer-to-peer network where nobody has special authority over the execution, and thus they allow to implement tokens of value, ownership, voting, and other kinds of logic.

When deploying contracts, you should use the latest released version of Ylem. This is because breaking changes, as well as new features and bug fixes are introduced regularly.

Build and Install

Instructions about how to build and install the Ylem compiler can be found in the Ylem documentation.

Example

A "Hello World" program in Ylem is of even less use than in other languages, but still:

// SPDX-License-Identifier: MIT
pragma solidity >=0.6.0 <0.9.0;

contract HelloWorld {
    function helloWorld() external pure returns (string memory) {
        return "Hello, World!";
    }
}

To get started with Ylem, you can use Remix, which is a browser-based IDE. Here are some example contracts:

  1. Voting
  2. Blind Auction
  3. Safe remote purchase
  4. Micropayment Channel

Documentation

The Ylem documentation is hosted at Read the docs.

Development

Ylem is still under development. Contributions are always welcome! Please follow the Developers Guide if you want to help.

You can find our current feature and bug priorities for forthcoming releases in the projects section.
