The ixWrapperDeposit instruction deposits base assets into a tranching market. The wrapper mints SY from the base asset, deposits SY into the selected tranche, and mints tranche LP shares.
Usage
import { Transaction, sendAndConfirmTransaction } from "@solana/web3.js";
import { TrancheSide } from "@exponent-labs/exponent-sdk/client/tranching";
const { ixs, setupIxs } = await market.ixWrapperDeposit({
user: wallet.publicKey,
trancheSide: TrancheSide.Senior,
amountBase: 1_000_000_000n, // raw base-token units
minLpOut: 0n, // raw Senior LP units; set above 0 for output protection
});
const tx = new Transaction().add(...setupIxs, ...ixs);
const signature = await sendAndConfirmTransaction(connection, tx, [wallet]);

Returns
Returns an object with:

Deposits update market NAV before minting LP shares. Use minLpOut if the transaction depends on a specific output amount.
