# Burn LP Tokens (v1)

Burn all liquidity tokens to free liquidity from a pool

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

const USER_WALLET_ADDRESS = ""; // ! replace with your address

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

const router = client.open(new DEX.v1.Router());

const pool = client.open(await router.getPool({
  token0: "EQA2kCVNwVsil2EM2mB0SkXytxCqQjS4mttjDpnXmwG9T6bO", // STON
  token1: "EQBX6K9aXVl3nXINCyPPL86C4ONVmQ8vK360u6dykFKXpHCa", // GEMSTON
}));

const lpTokenWallet = client.open(await pool.getJettonWallet({
  ownerAddress: USER_WALLET_ADDRESS,
}));

const lpTokenWalletData = await lpTokenWallet.getWalletData();

const txParams = await pool.getBurnTxParams({
  amount: lpTokenWalletData.balance,
  responseAddress: USER_WALLET_ADDRESS,
  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 [doc section about transaction sending guide](/developer-section/common/transaction-sending.md) with examples for different libraries.
