Ethereum will see the Dencun upgrade on March 13, before which we should prepare zetaclient to suport new transaction type

[ws4charlie]

Describe the Issue
Dencun upgrade introduced a new transaction type, blob-carrying transaction, to benefit layer-2 applications. We simply skip the new transaction type in Athens which is a temporary fix. We should be able to observe blob-carrying transactions if it's a gas token deposit to Tss address.

Expected Outcome
zetaclient should be able to parse and observe new transaction type without error.

@ws4charlie this is a change in the ZetaClient? Why setting observer label?

I will see if a can create a calendar in the project board to set a time to complete the issue.

Just removed mainnet label, we can delete it now that mainnet is launched
