Strip (SY) - Exponent Docs

The ixStrip method on the Vault class creates a transaction instruction that strips SY tokens into equal amounts of PT and YT.

This method takes SY tokens directly. If you want to strip from a base asset (e.g., USDC), use ixStripFromBase instead.

Usage

import { Vault, 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 vault = await Vault.load(LOCAL_ENV, connection, vaultAddress);

const ix = vault.ixStrip({
  syIn: 1_000_000n,
  depositor: wallet.publicKey,
});

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

Required Parameters

Parameter	Type	Description
`syIn`	`bigint`	Amount of SY tokens to strip
`depositor`	`PublicKey`	The depositor’s wallet public key

Optional Parameters

Parameter	Type	Description
`sySrc`	`PublicKey`	Source SY token account. Defaults to depositor’s ATA
`ptDst`	`PublicKey`	Destination PT token account. Defaults to depositor’s ATA
`ytDst`	`PublicKey`	Destination YT token account. Defaults to depositor’s ATA

Returns

Returns a TransactionInstruction that strips SY into PT and YT. The number of PT and YT minted equals syIn × exchangeRate.
