Deposit SY - Exponent Docs

The ixDeposit instruction deposits existing SY into the selected tranche and mints Senior or Junior LP shares. Use this when your integration already holds SY and does not need base-asset wrapping.

Usage

import { Transaction, sendAndConfirmTransaction } from "@solana/web3.js";
import { TrancheSide } from "@exponent-labs/exponent-sdk/client/tranching";

const ix = market.ixDeposit({
  user: wallet.publicKey,
  trancheSide: TrancheSide.Junior,
  amountIn: 1_000_000_000n, // raw SY units
  minLpOut: 0n,             // raw Junior LP units; set above 0 for output protection
  tokenSrc: userSyTokenAccount,
  tokenLpDst: userJuniorLpTokenAccount,
});

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

Behavior

The instruction:

Syncs the market against the current SY exchange rate.
