# RpcSchema

Utility types for working with Ethereum JSON-RPC namespaces & schemas.

## Functions

| Name                | Description                         |
| ------------------- | ----------------------------------- |
| [`RpcSchema.from`](/api/RpcSchema/from) | Instantiates a statically typed Schema. This is a runtime-noop function, and is purposed to be used as a type-level tag to be used with [`Provider.from`](/api/Provider/from) or [`RpcTransport.fromHttp`](/api/RpcTransport/fromHttp). |

| [`RpcSchema.Eth`](/api/RpcSchema/types#rpcschemaeth) | Union of all JSON-RPC Methods for the `eth_` namespace. |
| [`RpcSchema.ExtractItem`](/api/RpcSchema/types#rpcschemaextractitem) | Extracts a schema item from a [`RpcSchema.Generic`](/api/RpcSchema/types#generic) or [`RpcSchema.MethodNameGeneric`](/api/RpcSchema/types#methodnamegeneric). |
| [`RpcSchema.ExtractMethodName`](/api/RpcSchema/types#rpcschemaextractmethodname) | Type-safe union of all JSON-RPC Method Names. |
| [`RpcSchema.ExtractParams`](/api/RpcSchema/types#rpcschemaextractparams) | Extracts parameters from a [`RpcSchema.Generic`](/api/RpcSchema/types#generic) or [`RpcSchema.MethodNameGeneric`](/api/RpcSchema/types#methodnamegeneric). |
