Understand the project

Practical overview

When it fits

Use it from a Cairo contract project when you need to verify the contract ABI for accurate Starkscan explorer information.

Who it is for

  • Cairo developers deploying or maintaining contracts on Starknet.
  • Developers using Starkscan who want contract transactions and events decoded against a verified ABI.

Documented uses

  • Verify a Cairo contract ABI so Starkscan can present accurate contract information.
  • Support human-readable decoding of contract transactions and events.
  • Provide accurate ABI information for reading and writing contract state through Starkscan.
Before you choose

Requirements & limits

The documented interface is a CLI invoked with npx or installed globally through npm. Nile and Protostar users have specified prerequisites.

  • Choose the npx invocation or global npm installation based on how you want to launch the CLI.
  • Nile users should activate their Python virtual environment; Protostar users should run protostar install first.
  • The README explains the purpose and invocation but not the verification interaction or error handling.

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

Start the verifier from a Cairo project

Invoke the Starkscan CLI from a project directory to verify a Cairo contract ABI.

Before you start

  • A Cairo contract project directory.
  • For Nile-based Python projects, an activated virtual environment.
  • For Protostar projects, run protostar install before using the tool.
  • Either npx or npm available for the documented invocation.

Steps

  1. From the project directory, run npx starkscan; or install the package globally with npm install -g starkscan.

  2. If using the global installation, run starkscan from the project directory.

Expected outcome

The documented CLI invocation starts the ABI verification tool for the project; the documentation links verification to accurate contract information and decoded transactions and events on Starkscan.

Guide limitations

  • The README does not describe the verification prompts, required contract inputs, or how to resolve verification errors.
