+> [!CAUTION]
+> This package has been deprecated.
+>
+> This package was originally created for MetaMask, but has been replaced by `@metamask/json-rpc-engine`, `@metamask/eth-json-rpc-middleware`, and `@metamask/eth-json-rpc-provider`.
+>
+>Here is an example of how to create a provider using those packages:
+>
+> ```typescript
+>import { providerFromMiddleware } from '@metamask/eth-json-rpc-provider';
+>import { createFetchMiddleware } from '@metamask/eth-json-rpc-middleware';
+>
+>const rpcUrl = '[insert RPC URL here]';
+>
+>const fetchMiddleware = createFetchMiddleware({ rpcUrl });
+>const provider = providerFromMiddleware(fetchMiddleware);
+>
+>provider.sendAsync(
+>  { id: 1, jsonrpc: '2.0', method: 'eth_chainId' },
+>  (error, response) => {
+>    if (error) {
+>      console.error(error);
+>    } else {
+>      console.log(response.result);
+>    }
+>  }
+>);
+>```
