# Sherpa

> Delta-neutral USDC yield vaults on Monad

<Info>
  **TVL:** \~\$3M | **Type:** Delta-Neutral USDC Vault | **Docs:** [sherpa.trade](https://sherpa.trade)
</Info>

## Overview

Sherpa runs delta-neutral strategies to generate yield on USDC without directional market exposure. Depositors receive vault shares; yield is accrued continuously and reflected in the share price. Multiple vaults may run distinct strategies with different risk/reward profiles.

## Functions

### getSherpaVaults()

Returns all active Sherpa vaults with current APY and total assets.

**Returns** `SherpaVault[]`

| Field         | Type       | Description                               |
| ------------- | ---------- | ----------------------------------------- |
| `address`     | `string`   | Vault contract address                    |
| `asset`       | `string`   | Underlying token address (typically USDC) |
| `totalAssets` | `bigint`   | Total assets under management (raw)       |
| `apy`         | `number`   | Current APY as a decimal (e.g. `0.118`)   |
| `strategy`    | `string`   | Strategy description or name              |
| `protocol`    | `'sherpa'` | Protocol identifier                       |

```typescript theme={null}
const vaults = await sdk.getSherpaVaults()
// → [
//   { address: '0x...', asset: '0x...', totalAssets: 2400000n, apy: 0.118, strategy: 'delta-neutral-usdc', protocol: 'sherpa' },
// ]
```

### getSherpaVault(address)

Returns data for a single Sherpa vault by address.

| Parameter | Type     | Description            |
| --------- | -------- | ---------------------- |
| `address` | `string` | Vault contract address |

**Returns** `SherpaVault`

```typescript theme={null}

// → { address: '0x...', apy: 0.118, strategy: 'delta-neutral-usdc', protocol: 'sherpa' }
```

### getSherpaAPY()

Returns the best current APY across all Sherpa vaults.

**Returns** `number`

```typescript theme={null}
const apy = await sdk.getSherpaAPY()
// → 0.118
```

### getSherpaTVL()

Returns total value locked across all Sherpa vaults in USD.

**Returns** `number`

```typescript theme={null}
const tvl = await sdk.getSherpaTVL()
// → 3100000
```

## Usage Example

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

const sdk = new Rampart()

const vaults = await sdk.getSherpaVaults()
const apy = await sdk.getSherpaAPY()

console.log(`Sherpa best APY: ${(apy * 100).toFixed(2)}%`)
console.log(`Active vaults: ${vaults.length}`)

for (const v of vaults) {
  console.log(`  ${v.strategy}: ${(v.apy * 100).toFixed(2)}% APY`)
}
```
