Stablecoins et paiements

Stablecoin Studio is a comprehensive toolkit designed to enable developers to create, manage, and operate stablecoins on the Hedera Hashgraph network. It provides a full stack solution including Solidity smart contracts, a TypeScript SDK, a command-line interface (CLI), a backend service for multisignature transaction management, and a React-based web UI. This suite allows developers to deploy new stablecoins, assign roles for token operations, and integrate stablecoins into their applications with ease. The platform supports advanced features such as role-based permissions, supply control split into cash-in and burn roles, and multisignature account management for enhanced security.

The platform addresses the lack of out-of-the-box stablecoin solutions on Hedera by offering an upgradeable smart contract architecture using proxy contracts and a factory contract to streamline stablecoin deployment. Developers can customize key assignments for token operations, enabling flexible governance models. Stablecoin Studio also supports proof of reserve integration compatible with Chainlink data feeds, allowing stablecoins to be backed by real-world assets or fiat collateral, which is critical for maintaining token stability.

Multisignature functionality is a key differentiator, enabling complex key structures for transaction authorization, which enhances security and governance. The backend service manages multisig transactions by collecting signatures before submitting them to the Hedera network, with a strict time window for transaction validity. The project follows enterprise-grade development practices including domain-driven design, hexagonal architecture, and command-query separation, ensuring maintainability and scalability. Developers can get started by installing dependencies via npm, deploying the required factory contracts, and using the SDK or CLI to create and manage stablecoins. Comprehensive documentation and sample code are available to facilitate integration and development.
