The monitoring application shows confirmations and the transaction status for each Arbitrary Message Bridge validator, and can monitor transactions in both directions (when initiating a transaction from the "Home" or Foreign" chain). Usually, the Home chain (a.k.a. the Home side of the bridge) is a chain with fast and inexpensive operations, whereas the chain is slow transactions and high gas fees is the Foreign chain (a.k.a. the Foreign side of the bridge).
The main aim of the application is to track the status of requests the users are sending through AMB mediators and help to understand the reason why a particular request is not processed yet.
Transactions must use the Arbitrary Message Bridge contracts to be monitored. Transactions using a vanilla TokenBridge contracts (e.g. POA-POA20 or Dai-xDai) bridge are discoverable by the ALM app.
