# Gearbox

> Leveraged yield via Gearbox V3 credit accounts on Monad

<Info>
  **Type:** Leveraged Yield (Gearbox V3) | **Docs:** [docs.gearbox.finance](https://docs.gearbox.finance)
</Info>

## Overview

Gearbox V3 is a composable leverage protocol. **Passive LPs** deposit assets into Gearbox pools and earn interest from borrowers. **Active borrowers** open credit accounts and use leveraged capital across whitelisted DeFi protocols (Curve, Convex, Yearn-style vaults, etc.).

On Monad, the Rampart reads Gearbox pool data - total liquidity, utilization rate, and the APY passive LPs currently earn. This is the **passive yield** side; credit account management is out of scope.

## Types

```typescript theme={null}
type GearboxPool = {
  address: `0x${string}`
  asset: `0x${string}`          // underlying token
  apy: number                    // current passive LP APY
  totalLiquidity: number         // USD value of assets in the pool
  protocol: 'gearbox'
}
```

## Functions

### getGearboxPools()

Returns all Gearbox pools on Monad with their current APY and liquidity.

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

const sdk = new Rampart()
const pools = await sdk.getGearboxPools()
// → GearboxPool[]

pools.forEach(p => {
  console.log(
    `Pool ${p.address}: APY ${(p.apy * 100).toFixed(2)}%  ` +
    `Liquidity $${(p.totalLiquidity / 1e6).toFixed(1)}M`
  )
})
```

### getGearboxTVL()

Returns the total liquidity deposited across all Gearbox pools on Monad in USD.

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

console.log(`Gearbox TVL: $${(tvl / 1e6).toFixed(1)}M`)
```

## Contract Addresses

| Contract    | Address                                      |
| ----------- | -------------------------------------------- |
| PoolFactory | `0x9f0f0B07fFBf9C2F0a70B7bFdF9d5F84C434e1D8` |

<Note>
  Pool APY on Gearbox depends on utilization rate. Higher borrower demand = higher passive LP yield. APYs are more volatile than simple vault yields.
