# Lagoon Finance

> ERC-7540 async vault factory for institutional-grade yield on Monad

<Info>
  **Type:** ERC-7540 Async Vault Factory | **Docs:** [lagoon.finance](https://lagoon.finance)
</Info>

## Overview

Lagoon Finance deploys **ERC-7540 asynchronous vaults** - an extension of ERC4626 that separates deposit requests from actual execution. This allows vault managers to batch deposits and implement strategies that can't settle within a single transaction, making it suitable for institutional and complex yield strategies.

On Monad, the Lagoon factory has deployed multiple vaults with varying underlying assets. Each vault issues its own share token representing a pro-rata claim on vault assets.

## Types

```typescript theme={null}
type LagoonVault = {
  address: `0x${string}`
  asset: `0x${string}`         // underlying token
  totalAssets: bigint
  sharePrice: number            // assets per 1 share token
  protocol: 'lagoon'
}
```

## Functions

### getLagoonVaults()

Returns all Lagoon vaults deployed on Monad by querying the factory.

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

const sdk = new Rampart()
const vaults = await sdk.getLagoonVaults()
// → LagoonVault[]

vaults.forEach(v => {
  console.log(`Vault ${v.address}: sharePrice ${v.sharePrice.toFixed(6)}`)
})
```

### getLagoonTVL()

Returns the sum of `totalAssets` across all Lagoon vaults, denominated in USD.

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

console.log(`Lagoon total TVL: $${(tvl / 1e6).toFixed(2)}M`)
```

## Contract Addresses

| Contract     | Address                                      |
| ------------ | -------------------------------------------- |
| VaultFactory | `0x11Ad2eBF5571E0CaC69a7f1B7FCfCF46F7b8E22D` |

<Note>
  ERC-7540 vaults have asynchronous deposit and redemption queues. Actual settlement may take one or more blocks after a request is submitted. The `sharePrice` returned by `getLagoonVaults()` reflects the price at the time of the on-chain read.
