# Wrapper Sell PT

> Low-level instruction to sell PT for base assets in a single atomic operation

# createSellPtInstruction

Sells PT tokens for base assets in a single atomic operation. This is an alias for the sellPt instruction which handles the SY-to-base redemption internally via CPI remaining accounts. The caller supplies PT tokens and receives base tokens directly, without needing to manually redeem SY.

## Usage

```typescript theme={null}
import { createSellPtInstruction } from "@exponent-labs/exponent-sdk/client/clmm";
import { PublicKey } from "@solana/web3.js";

const ix = createSellPtInstruction({
  seller: sellerKeypair.publicKey,
  market: new PublicKey("market..."),
  tokenSyTrader: new PublicKey("tokenSyTrader..."),
  tokenPtTrader: new PublicKey("tokenPtTrader..."),
  tokenSyEscrow: new PublicKey("tokenSyEscrow..."),
  tokenPtEscrow: new PublicKey("tokenPtEscrow..."),
  addressLookupTable: new PublicKey("lookupTable..."),
  tokenProgram: new PublicKey("TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA"),
  syProgram: new PublicKey("syProgram..."),
  tokenFeeTreasurySy: new PublicKey("tokenFeeTreasurySy..."),
  tokenFeeTreasuryPt: new PublicKey("tokenFeeTreasuryPt..."),
  ticks: new PublicKey("ticks..."),
  eventAuthority: new PublicKey("eventAuthority..."),
  program: new PublicKey("program..."),
  amountPt: 1_000_000n,
  minBaseAmount: 950_000n,
  priceSpotLimit: 1.05,
  redeemSyRemAccountsUntil: 3,
});
```
