Sends a read-only call to the contract method. Returns the result that would happen if one were to send an
Ethereum transaction to this method, given the current state of the blockchain. Calls do not cost gas
since they don't modify state.
**Parameters:**
Name | Type | Default | Description |
------ | ------ | ------ | ------ |
`encoded` | string | - | ABI-encoded revert error. |
`callData` | `Partial<CallData>` | {} | - |
`defaultBlock?` | [BlockParam](#blockparam) | - | - |

Decode the ABI-encoded return data from a transaction
**Parameters:**
Name | Type | Description |
------ | ------ | ------ |
`returnData` | string | the data returned after transaction execution |
**Returns:** *[number, string, string]*
An array representing the output results in order. Keynames of nested structs are preserved.

Returns the ABI encoded transaction data needed to send an Ethereum transaction calling this method. Before
sending the Ethereum tx, this encoded tx data can first be sent to a separate signing service or can be used
to create a 0x transaction (see protocol spec for more details).

operator, or the approved address for this NFT. Throws if `_from` is
not the current owner. Throws if `_to` is the zero address. Throws if
`_tokenId` is not a valid NFT. When transfer is complete, this function
checks if `_to` is a smart contract (code size > 0). If so, it calls
`onERC721Received` on `_to` and throws if the return value is not
`bytes4(keccak256("onERC721Received(address,address,uint256,bytes)"))`.

# Class: MetamaskSubprovider
This class implements the [web3-provider-engine](https://github.com/MetaMask/provider-engine)
subprovider interface and the provider sendAsync interface.
It handles inconsistencies with Metamask implementations of various JSON RPC methods.
It forwards JSON RPC requests involving the domain of a signer (getAccounts,
sendTransaction, signMessage etc...) to the provider instance supplied at instantiation. All other requests
are passed onwards for subsequent subproviders to handle.
## Constructors
\+ **new MetamaskSubprovider**(`supportedProvider`: [SupportedProvider](#supportedprovider)): *[MetamaskSubprovider](#class-metamasksubprovider)*
*Defined in [subproviders/src/subproviders/metamask_subprovider.ts:19](https://github.com/0xProject/0x-monorepo/blob/9fe6c196a/packages/subproviders/src/subproviders/metamask_subprovider.ts#L19)*
Instantiates a new MetamaskSubprovider
**Parameters:**
Name | Type | Description |
------ | ------ | ------ |
`supportedProvider` | [SupportedProvider](#supportedprovider) | Web3 provider that should handle all user account related requests |
**Returns:** *[MetamaskSubprovider](#class-metamasksubprovider)*
## Methods
#### emitPayloadAsync

Emits a JSON RPC payload that will then be handled by the ProviderEngine instance
this subprovider is a part of. The payload will cascade down the subprovider middleware
stack until finding the responsible entity for handling the request.
**Parameters:**
Name | Type | Description |
------ | ------ | ------ |
`payload` | `Partial<JSONRPCRequestPayloadWithMethod>` | JSON RPC payload |
**Returns:** *`Promise<JSONRPCResponsePayload>`*
JSON RPC response payload
___
### handleRequest

*Defined in [subproviders/src/subproviders/metamask_subprovider.ts:39](https://github.com/0xProject/0x-monorepo/blob/9fe6c196a/packages/subproviders/src/subproviders/metamask_subprovider.ts#L39)*
This method conforms to the web3-provider-engine interface.
It is called internally by the ProviderEngine when it is this subproviders
turn to handle a JSON RPC request.
**Parameters:**
Name | Type | Description |
------ | ------ | ------ |
`payload` | `JSONRPCRequestPayload` | JSON RPC payload |
`next` | [Callback](#callback) | Callback to call if this subprovider decides not to handle the request |
`end` | [ErrorCallback](#errorcallback) | Callback to call if subprovider handled the request and wants to pass back the request. |
**Returns:** *`Promise<void>`*
___
### sendAsync
▸ **sendAsync**(`payload`: `JSONRPCRequestPayload`, `callback`: [ErrorCallback](#errorcallback)): *void*
*Defined in [subproviders/src/subproviders/metamask_subprovider.ts:117](https://github.com/0xProject/0x-monorepo/blob/9fe6c196a/packages/subproviders/src/subproviders/metamask_subprovider.ts#L117)*
This method conforms to the provider sendAsync interface.
Allowing the MetamaskSubprovider to be used as a generic provider (outside of Web3ProviderEngine) with the
addition of wrapping the inconsistent Metamask behaviour
**Parameters:**
Name | Type | Description |
------ | ------ | ------ |
`payload` | `JSONRPCRequestPayload` | JSON RPC payload |
`callback` | [ErrorCallback](#errorcallback) | - |
**Returns:** *void*

Set's the subprovider's engine to the ProviderEngine it is added to.
This is only called within the ProviderEngine source code, do not call
directly.
**Parameters:**
Name | Type | Description |
------ | ------ | ------ |
`engine` | `Web3ProviderEngine` | The ProviderEngine this subprovider is added to |
**Returns:** *void*

This type defines the schema of the artifact.json file generated by Sol-compiler
schemaVersion: The version of the artifact schema
contractName: The contract name it represents
networks: Network specific information by network (address, id, constructor args, etc...)
compilerOutput: The Solidity compiler output generated from the specified compiler input
description (http://solidity.readthedocs.io/en/v0.4.24/using-the-compiler.html#compiler-input-and-output-json-description)
compiler: The compiler settings used
sourceCodes: The source code of the contract and all it's dependencies
sources: A mapping from source filePath to sourceMap id
sourceTreeHashHex: A unique hash generated from the contract source and that of it's dependencies.
If any of the sources change, the hash would change notifying us that a re-compilation is necessary

## Object literals
#### `Const` transactionHashUtils
#### ▪ **transactionHashUtils**: *object*
*Defined in [order-utils/src/transaction_hash.ts:9](https://github.com/0xProject/0x-monorepo/blob/9fe6c196a/packages/order-utils/src/transaction_hash.ts#L9)*
#### getTransactionHashBuffer
▸ **getTransactionHashBuffer**(`transaction`: `ZeroExTransaction` | `SignedZeroExTransaction`): *`Buffer`*
*Defined in [order-utils/src/transaction_hash.ts:41](https://github.com/0xProject/0x-monorepo/blob/9fe6c196a/packages/order-utils/src/transaction_hash.ts#L41)*
Computes the transactionHash for a supplied 0x transaction.
**Parameters:**
Name | Type | Description |
------ | ------ | ------ |
`transaction` | `ZeroExTransaction` \| `SignedZeroExTransaction` | An object that conforms to the ZeroExTransaction or SignedZeroExTransaction interface definitions. |
**Returns:** *`Buffer`*
A Buffer containing the resulting transactionHash from hashing the supplied 0x transaction.
#### getTransactionHashHex
▸ **getTransactionHashHex**(`transaction`: `ZeroExTransaction` | `SignedZeroExTransaction`): *string*
*Defined in [order-utils/src/transaction_hash.ts:30](https://github.com/0xProject/0x-monorepo/blob/9fe6c196a/packages/order-utils/src/transaction_hash.ts#L30)*
Computes the transactionHash for a supplied 0x transaction.
**Parameters:**
Name | Type | Description |
------ | ------ | ------ |
`transaction` | `ZeroExTransaction` \| `SignedZeroExTransaction` | An object that conforms to the ZeroExTransaction or SignedZeroExTransaction interface definitions. |
**Returns:** *string*
Hex encoded string transactionHash from hashing the supplied order.
#### isValidTransactionHash
▸ **isValidTransactionHash**(`transactionHash`: string): *boolean*
*Defined in [order-utils/src/transaction_hash.ts:17](https://github.com/0xProject/0x-monorepo/blob/9fe6c196a/packages/order-utils/src/transaction_hash.ts#L17)*
Checks if the supplied hex encoded 0x transaction hash is valid.
Note: Valid means it has the expected format, not that a transaction with the transactionHash exists.
Use this method when processing transactionHashes submitted as user input.
**Parameters:**
Name | Type | Description |
------ | ------ | ------ |
`transactionHash` | string | Hex encoded transactionHash. |
**Returns:** *boolean*
Whether the supplied transactionHash has the expected format.
