> shMON liquid staking with MEV-boosted yield on Monad

<Info>

## Overview

FastLane issues **shMON** — a liquid staking token that captures both native staking rewards and MEV income redirected back to stakers. The exchange rate between shMON and MON increases continuously as rewards accrue.

## Functions

### getFastLaneLST()

Returns the full `LSTStats` snapshot for shMON.

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

const sdk = new Rampart()
const lst = await sdk.getFastLaneLST()

console.log(`shMON APR: ${(lst.apr * 100).toFixed(2)}%`)
console.log(`Exchange rate: 1 shMON = ${lst.exchangeRate} MON`)
```

### getFastLaneExchangeRate()

Returns the current shMON/MON exchange rate.

```typescript theme={null}
const rate = await sdk.getFastLaneExchangeRate()
// → number, e.g. 1.543
```

### getFastLaneTVL()

Returns total MON deposited, denominated in USD.

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