# Submitting a native transaction request

Before requesting a transaction, ensure that you encode the value in hexadecimal format.

```javascript
const amountToSend = BigInt("10000000000000000");  //0.1 NATIVE TOKEN (ETH/BNB/AVAX etc)
const value = "0x" + amountToSend.toString(16)
```

You also need to add the necessary parameters before requesting a transaction.

```javascript
const from = userAddress //the address you're sending from (connected users address)
const to = "0x0000000000000000000000000000000000000000" // the address you're sending the transaction to 
const data = "0x" // the data which is always 0x when sending a native transaction
```

Next, create the transaction object

```javascript
const tx = {
  from,
  to,
  data,
  value,
},
```

Finally, obtain the chain ID, which can be found at the following URL: (<https://chainlist.org>)

```javascript
const chainId = 1; // ETH chain id
```
