Provide Liquidity Classic - Exponent Docs

The ixProvideLiquidityClassic method on the MarketThree class provides liquidity using a combination of base assets and PT tokens. Unlike ixWrapperProvideLiquidity which only takes base assets, this method allows you to supply PT tokens you already hold alongside base assets.

Usage

import { MarketThree, LOCAL_ENV } from "@exponent-labs/exponent-sdk";
import { Connection, PublicKey, Transaction, sendAndConfirmTransaction, Keypair } from "@solana/web3.js";

const connection = new Connection("https://api.mainnet-beta.solana.com");
const market = await MarketThree.load(LOCAL_ENV, connection, marketAddress);

const { ixs, setupIxs, signers } = await market.ixProvideLiquidityClassic({
  depositor: wallet.publicKey,
  amountBase: 5_000_000_000n,
  amountPt: 5_000_000_000n,
  minLpOut: 9_000_000_000n,
  lowerTickApy: 0.05,  // 5% APY
  upperTickApy: 0.15,  // 15% APY
});

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

The signers array contains the generated LP position keypair. You must include it when signing the transaction.
