Description	Solang is a portable compiler for the Solidity language that targets Solana, Substrate (Polkadot), and ewasm. It is written in Rust, and leverages the LLVM infrastructure for the compiler backend.

The Solidity language is the [most popular programming language for smart contracts](https://101blockchains.com/smart-contract-programming-languages/). However, the existing Solidity compiler only targets the Ethereum virtual machine. The Solang project aims to make Solidity available for other blockchains, and focuses on maintaining compatibility with Solc, so that developers can use their existing codebase for blockchains other than Ethereum with minimal modifications.

The purpose of Solang is two-fold: first of all, developers with solidity language knowledge can develop new smart contracts for non-ethereum blockchains in Solidity, so they do not have to learn a new language. Secondly, there is a large amount of existing Solidity contracts available, which can be recompiled for a different blockchain.

Currently, Solang targets the following blockchains:

- [Solana](https://solana.com)
- [Substrate Polkadot](https://substrate.io)
- [Ethereum ewasm](https://ewasm.readthedocs.io)

At the time of writing, these chains are the 2nd, 9th, and 11th by market capitalization according [coinmarketcap](https://coinmarketcap.com/) (the coins are listed by market cap).

Note that public Ethereum does not currently support ewasm, however work for ewasm support on Ethereum is underway.

Any other blockchain that wishes to have Solidity language support is welcome to a new target to the Solang project. The cosmos blockchain [grant foundation](https://interchain.io/) has said it would [support a grant for adding CosmWasm support](https://github.com/hyperledger-labs/Solang/issues/582).

The goal of Solang is to bring the Solidity language to as many blockchains as possible. Writing a production quality compiler is a complex task, so collaboration between blockchains will be hugely beneficial.

The success of the project can be measured by the number of projects that use Solang as a compiler.
