Loopr

Loopr is an experimental Web3 social project that explores interaction mechanisms based on non-transferable tokens (SSBTs). Through lightweight operations such as follow, sublimate, and share, it aims to prototype a spiritually-driven social network. The project is currently in the Proof of Concept (PoC) stage.

💡 Core Concept

1. SSBT (Sublimable Soul Bound Token)

SSBT is a sublimable, soul-bound token representing a user’s spiritual value. Its design includes:

• Non-transferable: Cannot be traded on markets, avoiding incentive misalignment caused by financial speculation;
• Inflatable: Anyone can mint SSBT for any address by transferring ERC20;
• Sublimable: Users can "sublimate" their SSBTs, redistributing them to followed users while receiving ERC20 rewards.

🚀 Modules Overview

Smart Contracts (contracts/)

Written in Cairo and deployed on Starknet, the contract suite includes:

• SSBTToken: Implements follow/unfollow logic, SSBT distribution and sublimation, ERC20 reward emission, and admin control;
• Access control: Uses OpenZeppelin’s OwnableComponent for on-chain permission management.

Frontend (frontend/)

Built with React and integrated with Starknet using Starknet React Hooks for seamless on-chain interaction.

Scripts (scripts/)

Deployment and verification scripts to initialize contracts and facilitate frontend integration:

• Contract declaration, deployment, and utility helpers
• Optimized for local testing and CI deployment pipelines
