# Mu Digital

> RWA structured credit with AZND, loAZND, and muBOND on Monad

<Info>
  **Type:** RWA Structured Credit | **Docs:** [mu.xyz](https://mu.xyz)
</Info>

## Overview

Mu Digital brings real-world asset (RWA) structured credit products on-chain. The protocol issues **AZND** (senior tranche), **loAZND** (junior tranche), and **muBOND** (fixed-rate bond) — each backed by institutional credit facilities. Rampart reads vault APYs and TVL for all Mu tranches.

## Functions

### getMuVaults()

Returns all active Mu Digital vaults across tranches.

```typescript theme={null}
import { Rampart } from 'rampart-monad'

const sdk = new Rampart()
const vaults = await sdk.getMuVaults()
// → MuVault[]

vaults.forEach(v => {
  console.log(`${v.name}: ${(v.apy * 100).toFixed(2)}% APY | TVL $${(v.tvl / 1e6).toFixed(1)}M`)
})
```

### getMuTVL()

Returns total value locked across all Mu Digital vaults in USD.

```typescript theme={null}
const tvl = await sdk.getMuTVL()
// → number (USD)
```
