+### evmMethod
+
+If there are EVM methods that are not supported by the web3 library you use, Embark exposes the global function `evmMethod` that lets you call the RPC method directly.
+
+#### Syntax
+`evmMethod(rpcMethodName, parameters)`
+
+ - `rpcMethodName`: [string] Name of the RPC method to call.
+ - `parameters`: [Array<any>] Optional array of parameters, as specified by the RPC method API.
+
+#### Usage
+For example, let's say you are using `web3.js` in your tests, but would like to call the `eth_signTypedData` RPC method. Because `web3.js` does not support this method, it won't be possible to use `web3.js` for this call. Instead, we can call the `eth_signTypedData` RPC method in our tests using the global `evmMethod` function:
+
+```javascript
+ const signature = await evmMethod("eth_signTypedData", [
+  accounts[0],
+  data
+]);
+```
