# Curvance

> Multi-collateral lending - largest TVL lender on Monad at ~$58.9M

<Info>
  **TVL:** \~\$58.9M | **Type:** Multi-Collateral Lending | **Docs:** [docs.curvance.com](https://docs.curvance.com)
</Info>

## Overview

Curvance is the largest lending protocol on Monad by TVL. It supports multi-collateral positions, meaning users can post several different assets as collateral simultaneously. Each market has its own collateral factor and independent supply/borrow APY.

## Functions

### getCurvanceMarkets()

Returns all active Curvance lending markets with their current rates and liquidity.

**Returns** `CurvanceMarket[]`

| Field              | Type     | Description                                |
| ------------------ | -------- | ------------------------------------------ |
| `address`          | `string` | Market contract address                    |
| `asset`            | `string` | Underlying token address                   |
| `collateralFactor` | `number` | Max LTV for this asset (e.g. `0.75` = 75%) |
| `supplyAPY`        | `number` | Current supply APY as a decimal            |
| `borrowAPY`        | `number` | Current borrow APY as a decimal            |
| `totalSupply`      | `bigint` | Total supplied liquidity (raw)             |
| `totalBorrow`      | `bigint` | Total borrowed amount (raw)                |

```typescript theme={null}
const markets = await sdk.getCurvanceMarkets()
// → [
//   { address: '0x...', asset: '0x...', collateralFactor: 0.80, supplyAPY: 0.052, borrowAPY: 0.088, protocol: 'curvance' },
//   { address: '0x...', asset: '0x...', collateralFactor: 0.65, supplyAPY: 0.031, borrowAPY: 0.059, protocol: 'curvance' },
// ]
```

### getCurvanceTVL()

Returns total value locked across all Curvance markets in USD.

**Returns** `number`

```typescript theme={null}
const tvl = await sdk.getCurvanceTVL()
// → 58900000
```

### getCurvanceMarket(address)

Returns data for a single Curvance market by its contract address.

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

**Returns** `CurvanceMarket`

```typescript theme={null}
const market = await sdk.getCurvanceMarket('0x...')
// → { address: '0x...', asset: '0x...', collateralFactor: 0.80, supplyAPY: 0.052, borrowAPY: 0.088 }
```

## Usage Example

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

const sdk = new Rampart()

const markets = await sdk.getCurvanceMarkets()

// Find best supply rate
const bestSupply = markets.sort((a, b) => b.supplyAPY - a.supplyAPY)[0]
console.log(`Best Curvance supply: ${(bestSupply.supplyAPY * 100).toFixed(2)}%`)

// Find highest collateral factor (most capital efficient)
const highestLTV = markets.sort((a, b) => b.collateralFactor - a.collateralFactor)[0]
console.log(`Highest LTV: ${(highestLTV.collateralFactor * 100).toFixed(0)}% for ${highestLTV.asset}`)
```
