Practical overview

When it fits

Use Solang when the contract language is Solidity but the intended deployment environment is Solana, Polkadot or Soroban rather than a single Ethereum-oriented target.

Who it is for

  • Solidity developers targeting Solana, Polkadot or Stellar Soroban.
  • Teams building workflows that compile Solidity for more than one supported blockchain ecosystem.
  • Developers working with command-line blockchain tooling.

Documented uses

  • Compile Solidity contracts for Solana-based deployments.
  • Compile Solidity contracts for Polkadot or Substrate-based environments.
  • Compile Solidity contracts for Stellar Soroban.
  • Create a multi-chain Solidity development workflow across supported targets.
Before you choose

Requirements & limits

The repository is public and licensed under Apache-2.0. Solang is available as a macOS Homebrew cask, while installation instructions for other operating systems are provided in the project documentation. It is included in the Solana Tools Suite from version 1.16.3 and higher.

  • Target ecosystem: Solang provides separate targets for Solana, Polkadot and Soroban.
  • Portability: the project describes Solidity 0.8 compatibility but warns of caveats caused by underlying blockchain differences.
  • Output workflow: Polkadot compilation produces a .contract artifact, while Soroban compilation produces a .wasm file for Stellar CLI deployment.
  • Feature coverage: the project publishes a Soroban support matrix and identifies several target and language improvements as ongoing work.
  • Tooling model: Solang is a command-line developer tool implemented in Rust and using LLVM.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Compile a Solidity contract for Polkadot

Produce a Polkadot contract artifact from the repository’s flipper example.

Before you start

  • Solang installed or the documented Solang container available.
  • The Solang repository and its Polkadot flipper example.

Steps

  1. Select the Polkadot flipper example from the Solang repository.

  2. Run solang compile --target polkadot examples/polkadot/flipper.sol.

  3. Use the resulting flipper.contract file with Contracts UI, as described by the repository.

Expected outcome

A `flipper.contract` artifact is produced for use with Contracts UI.

Guide limitations

  • The repository notes that Polkadot targets use the contracts pallet.
  • The command documents compilation and artifact use, not the full Contracts UI deployment procedure.
