Welcome to Project Casper Deployer!

CasperLabs Hackaton October 2022 👻 🎃🕯️

Project built with 😘♥💕❤ for Casper Blockchain

🏰 Deployed on Render at https://casper.onrender.com/ ( beta 🏚️🕸️🕷️)

📔 Project

This projects aims to ease interactions with Casper Blockchain during smart contracts development and for regular queries done with the Casper Client CLI

This project relies on casper-js-sdk and casper-rust-sdk to help with onboarding developers on the Casper Network and also users by providing better insights on Casper Blockchain concepts (URef, Dictionnaries etc..) and with giving the ability to deploy a smart contract signed with the Capser Signer.

✍️ Casper Signer

Using Chrome or a Chromium-based browser like Brave ? visit the Chrome Web Store, then download and install CasperLabs Signer extension

📜 CasperLabs Signer acts as your CSPR wallet, keeping your accounts and letting you sign deploys on the Casper Network to perform actions like staking, unstaking or sending your tokens to another person or an exchange account.

For Casper Signer Users

• Create/Import an Account using Signer
• 👛 Connect a Wallet
• 💸 Transfer CSPR

🏭 Tech Stack

• Blockchain ⛓️

• Frontend 🐇

• Backend 🦥

• Tests 🧪

🏗️ Architecture

Web Server

Web server is implemented in Express.js.

Api Server

Api server is implemented in NestJS+ Nx structure.

Client

UI is implemented in Angular.js + Nx structure.

Smart contracts

Smart contracts are implemented in Rust + Casper Smart contract Crate.

Folders at root directory is as follow :

• casper-sdk: contains the Casper Rust SDK in two versions, web and nodejs
• docker: contains Docker files
• wasm: contains client wasm files
• www: contains the Web application files
