sGHS - Stable Ghana Cedi

Our progress during this hackathon has been in 3 major fronts. 1. Platform development 2. Brand development and design - added some in the project description. We essentially have our branding nailed down. 3. Commencement of engagement with key stakeholders - regulators, potential corresponding bank partners, fintechs and mobile money platform Platform Development Progress Over the past three weeks, the sGHS project has moved from architecture design into a working onchain prototype deployed within the Arbitrum ecosystem. 1. Core Smart Contracts Implemented We built the core sGHS stablecoin smart contracts representing a programmable Ghana cedi onchain. The contracts include: • ERC-20 compatible token implementation • Controlled mint and burn functions for regulated issuance and redemption flows • Role based access control architecture for governance and operational security • Supply management logic aligned with real world reserve backed issuance design • Upgrade and security conscious contract structure The contracts compile cleanly and are configured for deployment across EVM networks, with key focus on Arbitrum. 2. Deployment on Arbitrum Sepolia We successfully deployed the sGHS smart contracts to Arbitrum Sepolia testnet, demonstrating: • Compatibility with Arbitrum’s rollup environment • Proper transaction execution under Arbitrum’s gas model • Functional minting and transfer operations • Onchain verification of contract state This confirms that sGHS is not just architecturally compatible with Arbitrum, but operationally live within its ecosystem. The Sepolia deployment allows: • External testing by contributors and reviewers • Integration experiments with Arbitrum native tooling • Realistic simulation of user flows under L2 conditions 3. Testing and Development Infrastructure We established a structured development workflow including: • Automated test coverage for minting, burning, transfer logic, and access controls • Local blockchain testing environments • Deployment scripts and environment configurations • Network specific configuration for Arbitrum Sepolia 4. Early UX Layer We began development of a minimal interaction layer enabling: • Wallet connection • Balance viewing • Mint and transfer interactions • Transaction confirmation within Arbitrum Sepolia 5. Documentation and Contributor Readiness The repository includes: • Setup instructions • Deployment steps • Testing commands • Clear project structure This allows new developers and ecosystem collaborators to quickly understand and build on the project. Summary of What Has Been Achieved in 3 Weeks ✔ Core sGHS stablecoin contracts implemented ✔ Governance and controlled issuance logic built ✔ Automated tests written and executed ✔ Deployment scripts configured ✔ Successful deployment on Arbitrum Sepolia ✔ Functional mint and transfer flows live on testnet ✔ Early user interface interaction layer started ✔ Developer documentation completed In three weeks, sGHS transitioned from concept to a live Arbitrum testnet deployment with functional smart contracts and working transaction flows. With the sGHS platform live on Arbitrum Sepolia, we are now focused on strengthening the monetary, liquidity, and infrastructure layers: • Integrating production grade FX oracle feeds for accurate GHS price referencing • Formalizing reserve management architecture and transparency reporting mechanisms • Conducting security reviews of issuance, redemption, and access control systems • Stress testing supply expansion and contraction workflows under realistic payment scenarios • Initiating pilot integrations with payment processors, fintechs, and liquidity venues within the Arbitrum ecosystem Our objective is to evolve sGHS from a functional testnet deployment into a robust, transparent, and institution ready Ghana cedi stablecoin platform capable of supporting real commerce, cross border settlement, and programmable financial services on Arbitrum.
