 More specifically, every method is by default a change method, unless annotated by `@view_method`.
 - Every contract will have a `metadata` method that returns a json that serializes the contract methods. For each method,
 the json serialization is of the form `{"parameters": {<param1>: <type1>, .. }, "returnType": <return_type>}`.
-The overall serialization is of the form `{"view_methods": {<method_name>: <method_metadata>, .. }, "change_methods": {<method_name>: <method_metadata>, .. }}`.

 As an concrete example, suppose we have a contract that maintains a counter on chain:
 
 ```typescript
 import { context, storage, near } from "./near";
 
-export function incrementCounter(): void {
-  let newCounter = storage.get<i32>("counter") + 1;
+export function incrementCounterBy(amount: i32 = 1): void {

   storage.set<i32>("counter", newCounter)
   near.log("Counter is now: " + newCounter.toString());
 }
 
-export function decrementCounter(): void {
