# Blockchain Infrastructure

At the heart of MasterCrafter lies a sophisticated blockchain infrastructure that ensures transparency, security, and economic sustainability. It is built on the **Solana blockchain**, chosen for its high throughput and low transaction costs and partially with the support of the **Solana Foundation.**

* **Smart Contracts**: used in crafting mechanism and recipe creation to ensure the consumption of ressources and faire distribution of wealth with full transparency and history.
* **Factory Contracts**: used in the mass minting and burning of MasterCrafter's tokenized items.
* **SOL.BRIDGE & SOLBRIDGE.CLIENT**: built in collaboration with the Solana Foundation in order to interact with SOL.BRIDGE server-side application using REST API calls.
