**Parameters**

Object - An object with the following fields 

1. `fromBlock` (optional): `QUANTITY` - the minimum block number from where to get the transactions
2. `toBlock` (optional): `QUANTITY` - the maximum block number from where to get the transactions.
3. `transferType` (optional): `DATA` - transfer type `(trx/erc20/erc721)`
4. `contractAddresses`(optional): `DATA`, 20 Bytes -  contract address (i.e. `0x1a2b3x`) or array of contract addresses
5. `offset`(optional):  `QUANTITY` - offset.
6. `limit`(optional): `QUANTITY` - limit  

```
"params": [
        {
            "contractAddress": "0xdac17f958d2ee523a2206206994597c13d831ec7",
            "fromBlock": 14046400,
            "toBlock": 14049300,
            "offset": 1,
            "limit": 10
        }
    ]
```

**Returns**

* `Array` - The list of all the transfers 
* Object schema:

1. blockNumber: : `QUANTITY` - the block number. null when its pending block.
2. blockTimestamp: `DATETIME` - the UTC DATETIME for when the block was collated.
3. transactionHash: `DATA`, 32 Bytes - hash of the transaction.
4. transactionIndex: `QUANTITY` - index of transactions in block 
5. logIndex: `QUANTITY` - index of transaction logs
6. contractAddress: `DATA`, 20 Bytes - contract address (i.e. `0x1a2b3x`)
7. transferType: `DATA`, transfer type `(trx/erc20/erc721)`
8. from: `DATA`, 20 Bytes - address of the sender.
9. to: `DATA`, 20 Bytes - address of the receiver. null when it's a contract creation transaction.
10. value: `QUANTITY` - value transferred.
11. fee: `QUANTITY`- fee of the transaction.
12. asset: `DATA`- `ETH` or the token's symbol. `null` if not defined in the contract and not available from our sources.
13. decimals: `QUANTITY` - contract decimal. `null` if not defined in the contract and not available from other sources.
14. error (optional):`BOOLEAN` - True, if the transaction was made with an error
