@Synthquest it looks like we already have some initial start on stablecoin spells, an example here for ethereum. if you go back a directory, other chains also exist. can we combine the efforts here with those existing ones, to have one approach on stablecoins? then we can have a crosschain spell on top of all chain specific ones, similar to tokens_erc20?

Sure, do you want to update the schema of these or keep the schema the same? I ask only because certain chains do not follow the same schema.

Optimism for instance:
https://github.com/duneanalytics/spellbook/blob/main/dbt_subprojects/tokens/models/tokens/optimism/tokens_optimism_erc20_stablecoins.sql

I'm also seeing a separate labels.stablecoins table on dune

@jeff-dude
I ran through adding in new chain tables, appending any stables from the existing tables, and normalizing to a standardized schema for all chains. Please let me know if we should change any naming conventions / column formats

this is looking good to me. plz do explicitly add schema property in each model though, rather than rely on value in dbt project file.
