**Project Scope**:
– This project is anticipated to be of small scope, given the relative ease of integrating the requested features. However, the developed smart contract will be utilized across multiple projects, underscoring its importance and potential for scalability.
– We are open to both fixed-price and hourly contracts. Proposals should include a detailed estimate of time and cost.

**Application Process**:
