The ixDepositLiquidity method on the MarketThree class creates a new LP position by depositing PT and SY tokens within a specified APY range.
This is a low-level method that requires you to already hold PT and SY tokens. To provide liquidity from base assets (e.g., USDC), use ixWrapperProvideLiquidity or ixProvideLiquidityClassic instead.

​
Usage

import { MarketThree, 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 market = await MarketThree.load(LOCAL_ENV, connection, marketAddress);

const { ix, signers } = market.ixDepositLiquidity({
  depositor: wallet.publicKey,
  ptInIntent: 5_000_000_000n,   // max PT to deposit
  syInIntent: 5_000_000_000n,   // max SY to deposit
  lowerTickKey: 0.05,           // 5% APY lower bound
  upperTickKey: 0.15,           // 15% APY upper bound
});

const tx = new Transaction().add(ix);
await sendAndConfirmTransaction(connection, tx, [wallet, signers]);
The signers value is the generated LP position keypair. You must include it when signing the transaction, otherwise the transaction will fail.
The lowerTickKey and upperTickKey parameters are decimal numbers — use 0.05 for 5% APY, not 500 or 50000.
