 The above snippet just listens for an event called `EventName`. For more complex use cases, you could also specify a `filter` like so:
 
 ```JavaScript
-myContract.events.EventName({ filter: { myParam: 1 } ,async (err, event) => {
-    if (err) {
-      console.error('Error on event', err)
-      return
-    }
-    // Do something
-  })

+  if (err) {
+    console.error('Error on event', err)
+    return
+  }
+  // Do something
+})
 
 ```
