# Provide Liquidity (v1)

Provide liquidity for a pool

## Jetton/Jetton pool deposit

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

const USER_WALLET_ADDRESS = ""; // ! replace with your address
const JETTON_0_ADDRESS = "EQA2kCVNwVsil2EM2mB0SkXytxCqQjS4mttjDpnXmwG9T6bO"; // STON
const JETTON_1_ADDRESS = "EQBX6K9aXVl3nXINCyPPL86C4ONVmQ8vK360u6dykFKXpHCa"; // GEMSTON

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

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

const txsParams = await Promise.all([
  // deposit 0.5 STON to the STON/GEMSTON pool and get at least 1 nano LP token
  router.getProvideLiquidityJettonTxParams({
    userWalletAddress: USER_WALLET_ADDRESS,
    sendTokenAddress: JETTON_0_ADDRESS,
    sendAmount: toNano("0.5"),
    otherTokenAddress: JETTON_1_ADDRESS,
    minLpOut: "1",
    queryId: 12345,
  }),
  // deposit 2 GEMSTON to the STON/GEMSTON pool and get at least 1 nano LP token
  router.getProvideLiquidityJettonTxParams({
    userWalletAddress: USER_WALLET_ADDRESS,
    sendTokenAddress: JETTON_1_ADDRESS,
    sendAmount: toNano("2.0"),
    otherTokenAddress: JETTON_0_ADDRESS,
    minLpOut: "1",
    queryId: 123456,
  }),
]);
```

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.

## TON/Jetton pool deposit

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

const USER_WALLET_ADDRESS = ""; // ! replace with your address
const JETTON_0_ADDRESS = "EQA2kCVNwVsil2EM2mB0SkXytxCqQjS4mttjDpnXmwG9T6bO"; // STON

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

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

const txsParams = await Promise.all([
  // deposit 1 TON to the STON/TON pool and get at least 1 nano LP token
  router.getProvideLiquidityTonTxParams({
    userWalletAddress: USER_WALLET_ADDRESS,
    proxyTon: new pTON.v1(),
    sendAmount: toNano("1"),
    otherTokenAddress: JETTON_0_ADDRESS,
    minLpOut: "1",
    queryId: 12345,
  }),
  // deposit 0.5 STON to the STON/TON pool and get at least 1 nano LP token
  router.getProvideLiquidityJettonTxParams({
    userWalletAddress: USER_WALLET_ADDRESS,
    sendTokenAddress: JETTON_0_ADDRESS,
    sendAmount: toNano("0.5"),
    otherTokenAddress: new pTON.v1().address,
    minLpOut: "1",
    queryId: 123456,
  }),
]);
