refund liquidity

This section contains SDK example for refunding undeposited liquidity in DEX

Refund tokens that were sent to LP account but weren't added to a liquidity pool yet

import { TonClient } from "@ton/ton";
import { DEX } from "@ston-fi/sdk";

const client = new TonClient({
  endpoint: "https://testnet.toncenter.com/api/v2/jsonRPC",
});

const router = client.open(
  DEX.v2_1.Router.CPI.create(
    "kQALh-JBBIKK7gr0o4AVf9JZnEsFndqO0qTCyT-D-yBsWk0v" // CPI Router v2.1.0
  )
);

const pool = client.open(
  await router.getPool({
    token0: "kQDLvsZol3juZyOAVG8tWsJntOxeEZWEaWCbbSjYakQpuYN5", // TestRED
    token1: "kQB_TOJSB7q3-Jm1O8s0jKFtqLElZDPjATs5uJGsujcjznq3", // TestBLUE
  })
);

const lpAccount = client.open(
  await pool.getLpAccount({
    ownerAddress: "", // ! replace with your address
  })
);

const txParams = await lpAccount.getRefundTxParams({
  queryId: 12345,
});

To execute the transaction, you need to send a transaction with these parameters to the blockchain. This code will be different based on the wallet you are using to send the tx from, so please check our with examples for different libraries.
