Understand the project

Practical overview

When it fits

Use it when evaluating an IR-centered smart-contract compiler framework or following its documented sample build workflow.

Who it is for

  • Smart-contract developers exploring an intermediate-representation-based compiler workflow.
  • Developers evaluating compiler tooling for blockchain projects.

Documented uses

  • Write or inspect smart-contract programs in the project's textual IR format.
  • Build a sample IR program using the documented Docker CLI command.
  • Consult the project's IR specification, examples and development guide.
Before you choose

Requirements & limits

The project is publicly available on GitHub and identifies its license as Apache-2.0.

  • The README provides a Docker-based sample build command and links to installation guidance, an IR specification and examples.
  • Several prominent capabilities, including Solidity/Yul input, AI intent analysis and formal verification, are listed as in progress rather than completed.
  • The README describes the project as under development.

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

Build the included Hello World IR example

Use the CLI Docker image to build the repository’s example IR program.

Before you start

  • Docker is available.
  • The repository’s sir/example/hello_world.ir file is accessible to the command.

Steps

  1. Run the command below.

    Documented command
    docker run smartir/cli:latest ir_cli build sir/example/hello_world.ir

  2. Check the CLI output to see the build result.

Expected outcome

The CLI is invoked to build the included Hello World IR program.

Guide limitations

  • The README provides the build command but does not describe expected output, build artifacts, or how to run the resulting program.
  • The project is still under development; listed Solidity/Yul support is in progress.
