# Class: Web3Wrapper
An alternative to the Web3.js library that provides a consistent, clean, promise-based interface.
### Hierarchy
* **Web3Wrapper**
### Constructors
## constructer
\+ **new Web3Wrapper**(`supportedProvider`: `SupportedProvider`, `callAndTxnDefaults`: `Partial<CallData>`): *[Web3Wrapper](#class-web3wrapper)*
*Defined in [web3_wrapper.ts:145](https://github.com/0xProject/0x-monorepo/blob/a6f43f536/packages/web3-wrapper/src/web3_wrapper.ts#L145)*
Instantiates a new Web3Wrapper.
**Parameters:**
Name | Type | Default | Description |
------ | ------ | ------ | ------ |
`supportedProvider` | `SupportedProvider` | - | - |
`callAndTxnDefaults` | `Partial<CallData>` | {} | Override Call and Txn Data defaults sent with RPC requests to the backing Ethereum node. |
**Returns:** *[Web3Wrapper](#class-web3wrapper)*
An instance of the Web3Wrapper class.
### Properties
## abiDecoder
• **abiDecoder**: *`AbiDecoder`*
*Defined in [web3_wrapper.ts:54](https://github.com/0xProject/0x-monorepo/blob/a6f43f536/packages/web3-wrapper/src/web3_wrapper.ts#L54)*
___
## isZeroExWeb3Wrapper
• **isZeroExWeb3Wrapper**: *boolean* = true
*Defined in [web3_wrapper.ts:53](https://github.com/0xProject/0x-monorepo/blob/a6f43f536/packages/web3-wrapper/src/web3_wrapper.ts#L53)*
Flag to check if this instance is of type Web3Wrapper
### Methods
## awaitTransactionMinedAsync
▸ **awaitTransactionMinedAsync**(`txHash`: string, `pollingIntervalMs`: number, `timeoutMs?`: undefined | number): *`Promise<TransactionReceiptWithDecodedLogs>`*
*Defined in [web3_wrapper.ts:568](https://github.com/0xProject/0x-monorepo/blob/a6f43f536/packages/web3-wrapper/src/web3_wrapper.ts#L568)*
Waits for a transaction to be mined and returns the transaction receipt.
Note that just because a transaction was mined does not mean it was
successful. You need to check the status code of the transaction receipt
to find out if it was successful, or use the helper method
awaitTransactionSuccessAsync.
**Parameters:**
Name | Type | Default | Description |
------ | ------ | ------ | ------ |
`txHash` | string | - | Transaction hash |
`pollingIntervalMs` | number | 1000 | How often (in ms) should we check if the transaction is mined. |
`timeoutMs?` | undefined \| number | - | How long (in ms) to poll for transaction mined until aborting. |
**Returns:** *`Promise<TransactionReceiptWithDecodedLogs>`*
Transaction receipt with decoded log args.
___
## awaitTransactionSuccessAsync
▸ **awaitTransactionSuccessAsync**(`txHash`: string, `pollingIntervalMs`: number, `timeoutMs?`: undefined | number): *`Promise<TransactionReceiptWithDecodedLogs>`*

Waits for a transaction to be mined and returns the transaction receipt.
Unlike awaitTransactionMinedAsync, it will throw if the receipt has a
status that is not equal to 1. A status of 0 or null indicates that the
transaction was mined, but failed. See:
https://github.com/ethereum/wiki/wiki/JavaScript-API#web3ethgettransactionreceipt
**Parameters:**
Name | Type | Default | Description |
------ | ------ | ------ | ------ |
`txHash` | string | - | Transaction hash |

Transaction receipt with decoded log args.
