# Setup

## Installation

```bash
yarn add @torch-finance/sdk @ton/ton @ton/crypto @ton/core
```

## Initialize (Mainnet)

```typescript
import { TorchSDK } from '@torch-finance/sdk';
const sdk = new TorchSDK();
```

## Initialize (Testnet / Custom Network)

```typescript
import { TonClient4 } from '@ton/ton';
import { TorchSDK, TorchSDKOptions } from '@torch-finance/sdk';

const tonClient = new TonClient4({ endpoint: "https://testnet-v4.tonhubapi.com/" });
const factoryAddress = Address.parse("testnet factory address")
const testnetOracle = "https://testnet-oracle.torch.finance"
const testnetAPI = "https://testnet-api.torch.finance"
const config: TorchSDKOptions = {
    tonClient: tonClient,
    factoryAddress: factoryAddress,
    oracleEndpoint: testnetOracle,
    apiEndpoint: testnetAPI,
  };
const sdk = new TorchSDK(config)
```
