# deserializeTransaction() <TitleWithCodeLink2 link="deserializeTransaction" />
Deserialize a transaction, convert raw data hex into an object.

## Usage
```js
utils.deserializeTx.deserializeTransaction(type, rawDataHex)
```

## Parameters
| Argument | Description                                                           | Type                       |
| -------- | --------------------------------------------------------------------- | -------------------------- |
| type  | The transaction type. | string                     |
| type  | The raw data hex of a transaction. | string                     |

**Note**:
1. In TronWeb v6.0.2, we used to deserialize a triggerSmartContract type transaction by `DTriggerSmartContract`. But we give a unified API to deserialize transactions with any type in this version. And `DTriggerSmartContract` no longer exists.
2. In TronWeb v6.1.0, we refactored the related code into a new file. As a result, the utils module has been updated to `deserializeTx`. And `DeserializeTransaction` has been renamed to `deserializeTransaction`, with the initial "D" now lowercase. 

## Supported type
- TriggerSmartContract
- FreezeBalanceV2Contract
- UnfreezeBalanceV2Contract
- CancelAllUnfreezeV2Contract
- DelegateResourceContract
- UnDelegateResourceContract
- WithdrawExpireUnfreezeContract
- TransferContract
- WithdrawBalanceContract
- WitnessCreateContract
- TransferAssetContract
- ParticipateAssetIssueContract
- AssetIssueContract
- UpdateAssetContract

## Return
Object - An object with the transaction data.

## Example
```js
import { TronWeb, utils } from 'tronweb';

const tronWeb = new TronWeb({
    fullHost: 'https://api.nileex.io',
    privateKey: 'your private key',
});
const contractAddress = 'TXYZopYRdj2D9XRtbG411XZZ3kM5VkAeBf'; // nile usdt address
const account = await tronWeb.createAccount();
const account2 = await tronWeb.createAccount();
const tx = (await tronWeb.transactionBuilder.triggerSmartContract(
    contractAddress,
    'transfer(address,uint256)',
    {
        txLocal: true,
        tokenId: '1000008',
        tokenValue: 100,
        feeLimit: 100 * (10 ** 6),
    },
    [
        { type: "address", value: account2.address.base58 },
        { type: "uint256", value: 100000000 }
    ],
    account.address.base58,
)).transaction;
const dResult = utils.deserializeTx.deserializeTransaction('TriggerSmartContract', tx.raw_data_hex);
```
