Hyphen Plugin

This plugin is designed to filter valid bridge transaction on the biconomy hyphen bridge

Overview

The Hyphen Bridge is relatively simple compared to other bridges. The same function is used regardless of wether you are bridging to or from L1. There is 3 functions we are watching, depositNative for native tokens like ETH (or MATIC for Polygon), depositErc20 for supported ERC-20 tokens, and depositErc20AndSwap which will swap out some of the bridged tokens for some of the native gas token on the receiving chain.

There is also a depositNativeAndSwap function, but I cannot find any instances of it being used in the wild, so I have chosen to exclude it from the filter.
