[Feature] index transactions on avax without contract address just with from to or data

Description

index transactions on avax without contract address just with from to or data

Are you aware of any blockers that must be resolved before implementing this feature? If so, which? Link to any relevant GitHub issues.

I now need to index metadata on Avalanche (AVAX), and the metadata is not directly related to smart contracts. However, when I create a The Graph project, it requires me to specify a smart contract. Is it possible to support projects without smart contracts, where I only need to focus on the 'from', 'to', and 'data' fields within transactions?

Some information to help us out

• Tick this box if you plan on implementing this feature yourself.
• I have searched the issue tracker to make sure this issue is not a duplicate.

La issue non indica file, test o punti di ingresso. Inizia identificando in che modo i progetti Graph richiedono uno smart contract e come l'indicizzazione delle transazioni Avalanche gestisce i campi from, to e data. Il lavoro è completo quando è stato definito e implementato il supporto per i progetti che indicizzano questi campi della transazione senza un indirizzo del contratto.
