# Smart Contract Architecture

* [**ERC-20 Contracts**](/technical-reference/smart-contract-architecture/erc-20-contracts.md)\
  Define the core tokens of the Mu Digital ecosystem, including **AZND** and **muBOND**.\
  Handle token standards, mint/redeem logic, and role-based permissions.
* [**loAZND Vault Contracts**](/technical-reference/smart-contract-architecture/staking-contracts.md)\
  Manage AZND deposits and issue **loAZND**, a yield-bearing token that accrues value through repricing.\
  Oversee reward accrual, cooldowns, lockup mechanics, and emissions distribution.
* [**Protocol Contracts**](/technical-reference/smart-contract-architecture/protocol-contracts.md)\
  Coordinate core system logic, including the **PrimaryMarket** (KYC-gated access), **PriceFeed**, **Access Manager**, and **Timelock Controller**.

### **Mu Core**

Mu Protocol merges real-world asset stability with DeFi-native efficiency, delivering predictable yield through transparent, composable products.

* **Real-World Asset Backing** – Each product is fully collateralized by verifiable, income-generating assets, with all positions transparently recorded and auditable on-chain.
* **Repricing-Based Yield** – Yield accrues through controlled price adjustments rather than rebasing, preserving ERC-20 and ERC-4626 compatibility and enabling seamless integration across DeFi.
* **Flexible, Integration-Ready Architecture** – Designed for interoperability with major DEXs, lending markets, and yield platforms, while supporting multiple product configurations such as instant-liquidity pools, fixed-term vaults, and diversified yield strategies.
* **Data Transparency** – All collateral details, performance metrics, and yield history are accessible in real time through on-chain data and public dashboards.
