Sell YT - Exponent Docs

The ixWrapperSellYt method on the MarketThree class converts YT (Yield Tokens) back into base assets by merging YT with PT to create SY and then redeeming SY for base in a single atomic operation.

Usage

import { MarketThree, LOCAL_ENV } from "@exponent-labs/exponent-sdk";
import { Connection, PublicKey, Transaction, sendAndConfirmTransaction } from "@solana/web3.js";

const connection = new Connection("https://api.mainnet-beta.solana.com");
const market = await MarketThree.load(LOCAL_ENV, connection, marketAddress);

const { ixs, setupIxs } = await market.ixWrapperSellYt({
  owner: wallet.publicKey,
  amount: 1_000_000_000n,
  minBaseOut: 900_000_000n,
});

const tx = new Transaction().add(...setupIxs, ...ixs);
const signature = await sendAndConfirmTransaction(connection, tx, [wallet]);

This is an async method because it needs to construct the SY redemption accounts from the market’s flavor configuration.

Required Parameters

Parameter	Type	Description
`owner`	`PublicKey`	The owner’s wallet public key
`amount`	`bigint`	Amount of YT tokens to sell
`minBaseOut`	`bigint`	Minimum amount of base asset to receive

Optional Parameters

Parameter	Type	Description
`tokenBaseTrader`	`PublicKey`	Destination base token account. Defaults to owner’s ATA
`tokenSyTrader`	`PublicKey`	Intermediate SY token account. Defaults to owner’s ATA
`tokenYtTrader`	`PublicKey`	Source YT token account. Defaults to owner’s ATA
`tokenPtTrader`	`PublicKey`	Intermediate PT token account. Defaults to owner’s ATA

Returns

Returns a Promise<PreparedInstruction> with the following structure:

{
  ixs: TransactionInstruction[],      // Main instructions to execute
  setupIxs: TransactionInstruction[]  // Setup instructions for creating ATAs
}

The setupIxs array contains instructions to create the necessary associated token accounts (ATAs) for SY, PT, YT, and base tokens. The ixs array contains the sell YT instruction followed by the flavor pre-instructions.
