# 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

*Defined in [subproviders/src/subproviders/metamask_subprovider.ts:19](https://github.com/0xProject/0x-monorepo/blob/762e0aec2/packages/subproviders/src/subproviders/metamask_subprovider.ts#L19)*

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 |
------ | ------ | ------ |

addition of wrapping the inconsistent Metamask behaviour

**Parameters:**

Name | Type | Description |
