# Wrapper Update Policy

> Low-level instruction to update a Squads policy via self-CPI with empty vault enforcement

# createWrapperUpdatePolicyInstruction

Updates an existing Squads policy on the vault via self-CPI using the vault's signer seeds. This instruction enforces that the vault has zero AUM (empty vault only), ensuring policy changes cannot be made while depositor funds are active. The manager must sign to authorize the update.

## Usage

```typescript theme={null}
import { createWrapperUpdatePolicyInstruction } from "@exponent-labs/exponent-sdk/client/vaults";
import { PublicKey, SystemProgram } from "@solana/web3.js";

const ix = createWrapperUpdatePolicyInstruction(
  {
    payer: payerKeypair.publicKey,
    vault: vaultAddress,
    manager: managerKeypair.publicKey,
    squadsSettings: squadsSettingsAddress,
    squadsSettingsTransaction: squadsSettingsTransactionPda,
    squadsProposal: squadsProposalPda,
    squadsPolicy: squadsPolicyPda,
    squadsProgram: SQUADS_PROGRAM_ID,
    systemProgram: SystemProgram.programId,
  },
  {
    policyConfig: {
      threshold: 2,
      permissions: { execute: {} },
      members: [managerKeypair.publicKey, sentinelKeypair.publicKey],
    },
  }
);
```
