The YtPosition class represents a user’s yield position for a specific vault. It tracks deposited YT balance, accrued interest, and emission rewards.

​
Loading a Position

​
By address

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

const connection = new Connection("https://api.mainnet-beta.solana.com");
const vault = await Vault.load(LOCAL_ENV, connection, vaultAddress);

// vault is optional — if omitted, it will be auto-loaded from the position's vault address
const ytPosition = await YtPosition.load(LOCAL_ENV, connection, positionAddress, vault);

​
By owner

const ytPosition = await YtPosition.loadByOwner(
  LOCAL_ENV,
  connection,
  wallet.publicKey,
  vault,
);

​
Multiple positions for one owner

// Accepts PublicKey[] or (Vault | PublicKey)[] — passing loaded Vault instances avoids redundant RPC fetches
const vaultAddresses = [vaultAddress1, vaultAddress2, vaultAddress3];

const positions = await YtPosition.loadAllByOwner(
  LOCAL_ENV,
  connection,
  wallet.publicKey,
  vaultAddresses,
);

​
Reading Position State

console.log("YT balance:", ytPosition.ytBalance);
console.log("Owner:", ytPosition.owner.toBase58());
console.log("Staged interest:", ytPosition.stagedInterest);

​
Available Properties

  • owner — Owner public key as string
  • ytBalance — YT balance as string
  • interest — Interest tracker with lastSeenIndex and staged
  • claimableInterest — Calculated claimable interest amount
