## subbridge\_convertRequestTxHashToHandleTxHash <a href="#subbridge_convertrequesttxhashtohandletxhash" id="subbridge_convertrequesttxhashtohandletxhash"></a>

The `subbridge_convertRequestTxHashToHandleTxHash` returns the corresponding "handle value transfer transaction" hash in the opposite chain for the given "request value transfer transaction" hash. "Request value transfer transaction" is a transaction initiated by a user, requesting a cross-chain value transfer. "Handle value transfer transaction" is the transaction created by the sub-bridge to handle the value transfer request from the user.

**Parameters**

| Name | Type         | Description                                     |
| ---- | ------------ | ----------------------------------------------- |
| Hash | 32-byte DATA | Hash of a "request value transfer" transaction. |

**Return Value**

| Name | Type         | Description                                                                                                                   |
| ---- | ------------ | ----------------------------------------------------------------------------------------------------------------------------- |
| Hash | 32-byte DATA | Hash of a "handle value transfer" transaction. zero hash means there is no corresponding "handle value transfer" transaction. |

**Example**

```javascript
