Events overview for vIBC
The Polymer testnet is currently in an early public testnet phase. Please be aware that during this phase, the network may be subject to instability, downtime, and data resets. Read the full disclaimer here.
When debugging the IBC packet lifecycle, the first step to take is to track down the packet during its lifecycle and where any potential issue arises.
For example, you can find reference to these events (or rather, the transaction they were emitted from) by looking at IBC explorer.
As an application developer, you'll be mostly looking at the events on the chains your application(s) live on, not Polymer itself in the middle. Below you find the sequence of events for all possible situations.
When connecting Ethereum L2s that don't have native IBC implementations, the virtual-to-virtual case is applicable.
