# ThresholdSignatureScheme

> Enum defining threshold signature schemes for MPC wallets

## Enum Definition

```typescript theme={"system"}
enum ThresholdSignatureScheme {
  TWO_OF_TWO = 'TWO_OF_TWO',
  TWO_OF_THREE = 'TWO_OF_THREE',
}
```

## Values

### `TWO_OF_TWO`

* **Description**: 2-of-2 threshold signature scheme
* **Parties**: 2 total parties
* **Threshold**: 2 signatures required
* **Client Threshold**: 1 client share
* **Server Threshold**: 1 server share
* **Use Case**: High security, requires all parties to sign

### `TWO_OF_THREE`

* **Description**: 2-of-3 threshold signature scheme
* **Parties**: 3 total parties
* **Threshold**: 2 signatures required
* **Client Threshold**: 2 client shares
* **Server Threshold**: 1 server share
* **Use Case**: Balanced security and availability

## Example

```typescript theme={"system"}
import { ThresholdSignatureScheme } from '@dynamic-labs-wallet/node';

// Create a wallet with 2-of-3 threshold
const wallet = await client.createWalletAccount({
  thresholdSignatureScheme: ThresholdSignatureScheme.TWO_OF_THREE,
  password: 'my-password'
});

// Check the threshold scheme
if (wallet.thresholdSignatureScheme === ThresholdSignatureScheme.TWO_OF_THREE) {
  console.log('Wallet uses 2-of-3 threshold scheme');
}
```

## Configuration

Each threshold signature scheme has specific configuration:

```typescript theme={"system"}
const MPC_CONFIG = {
  [ThresholdSignatureScheme.TWO_OF_TWO]: {
    numberOfParties: 2,
    threshold: 2,
    clientThreshold: 1,
    dynamicServerThreshold: 1,
  },
  [ThresholdSignatureScheme.TWO_OF_THREE]: {
    numberOfParties: 3,
    threshold: 2,
    clientThreshold: 2,
    dynamicServerThreshold: 1,
  },
};
```
