# Wrapper Collect Interest

> Low-level instruction to collect accrued interest with automatic SY redemption

# createWrapperCollectInterestInstruction

Builds a raw instruction that collects accrued interest from the orderbook with automatic SY redemption to the base asset. This combines the interest collection and SY redemption steps atomically.

## Usage

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

const ix = createWrapperCollectInterestInstruction(
  {
    trader: wallet.publicKey,
    orderbook: orderbookAddress,
    vault: vaultAddress,
    cpiAccountOrderbook: cpiAccountsOrderbook,
    tokenEscrowSy: orderbookEscrowSy,
    tokenSyTrader: userSyTokenAccount,
    systemProgram: SystemProgram.programId,
    syProgram: syProgramId,
    tokenProgram: TOKEN_PROGRAM_ID,
    exponentCore: EXPONENT_CORE_PROGRAM_ID,
    addressLookupTable: vaultLookupTable,
    eventAuthority: eventAuthorityPda,
    program: EXPONENT_ORDERBOOK_PROGRAM_ID,
  },
  {
    redeemSyAccountsUntil: 0,
  }
);
```
