createWrapperStripInstruction

Builds a raw instruction that wraps a base asset into SY and strips it into PT + YT in a single atomic operation. This combines the SY minting and stripping steps.

​
Usage

import { createWrapperStripInstruction } from "@exponent-labs/exponent-sdk/client/core";
import { PublicKey, SystemProgram } from "@solana/web3.js";

const ix = createWrapperStripInstruction(
  {
    depositor: wallet.publicKey,
    tokenSyDepositor: userSyTokenAccount,
    vault: vaultAddress,
    escrowSy: vaultEscrowSy,
    tokenYtDepositor: userYtTokenAccount,
    tokenPtDepositor: userPtTokenAccount,
    mintYt: ytMint,
    mintPt: ptMint,
    authority: vaultAuthority,
    vaultAddressLookupTable: vaultLookupTable,
    tokenProgram: TOKEN_PROGRAM_ID,
    escrowYt: vaultEscrowYt,
    userYieldPosition: userYieldPositionPda,
    vaultRobotYieldPosition: vaultYieldPosition,
    syProgram: syProgramId,
    systemProgram: SystemProgram.programId,
    eventAuthority: eventAuthorityPda,
    program: EXPONENT_CORE_PROGRAM_ID,
  },
  {
    amountBase: BigInt(1_000_000),
    mintSyAccountsUntil: 0,
  }
);
