# PolicyManager

> Attach and detach policies on context rules via kit.policies.

## Overview

Policies add additional authorization logic on top of signers - threshold multisig, spending limits, weighted voting, etc. Access the manager via `kit.policies`.

```typescript theme={null}
// Add a threshold policy to rule 0
await kit.policies.add(0, 'CPOLICY...', installParams);

// Remove it
await kit.policies.remove(0, 'CPOLICY...');
```

## Methods

### `add()`

Attach a policy contract to a context rule.

```typescript theme={null}
await kit.policies.add(
  contextRuleId: number,
  policyAddress: string,
  installParams: xdr.ScVal
);
```

**Example (threshold multisig):**

```typescript theme={null}
import { createThresholdParams } from 'smart-account-kit';

const params = createThresholdParams(2); // 2-of-N
const installParams = kit.convertPolicyParams(params);

await kit.policies.add(0, process.env.THRESHOLD_POLICY_ADDRESS!, installParams);
```

**Example (spending limit):**

```typescript theme={null}
import { createSpendingLimitParams, LEDGERS_PER_DAY } from 'smart-account-kit';

const params = createSpendingLimitParams(
  'CTOKEN...',
  BigInt(1000 * 10_000_000),  // 1000 tokens
  LEDGERS_PER_DAY
);
const installParams = kit.convertPolicyParams(params);

await kit.policies.add(0, process.env.SPENDING_LIMIT_POLICY_ADDRESS!, installParams);
```

### `remove()`

Detach a policy from a context rule.

```typescript theme={null}
await kit.policies.remove(
  contextRuleId: number,
  policyAddress: string
);
```

## Policy Types

The SDK ships with builders for all supported policy types:

| Builder                                             | Policy             | Description                |
| --------------------------------------------------- | ------------------ | -------------------------- |
| `createThresholdParams(m)`                          | Threshold          | M-of-N multisig            |
| `createWeightedThresholdParams(threshold, weights)` | Weighted threshold | Weighted voting            |
| `createSpendingLimitParams(token, limit, period)`   | Spending limit     | Time-limited per-token cap |

```typescript theme={null}
import {
  createThresholdParams,
  createWeightedThresholdParams,
  createSpendingLimitParams,
  LEDGERS_PER_HOUR,
  LEDGERS_PER_DAY,
  LEDGERS_PER_WEEK,
} from 'smart-account-kit';
```
