Specifying providers to be used when using Wallet class

[catinglasses]

Problem:
Application I'm working on heavily relies on performing frequent wallet.scan() where wallet = Wallet(wallet='some_name_placeholder', db_uri='db_uri_placeholder)

As such, I sometimes manage to hit rate limits on two (so far) APIs bitcoinlib uses to perform lookups. Specifically, let's say, blockchair and trezor.
Subjectively speaking, I don't think there are too many requests happening on a daily basis, so for now I'd like to refrain from setting up self-hosted Electrum server in order to replace Providers overall, given that it is a hustle and currently I don't know how to do that exactly, allowing myself to integrate it with Wallet-utlizing codebase.

What I want to do, is to manually specify which providers shall my Wallet instances use. I want to explicitly specify to cut out some providers (e.g. blockchair and trezor) OR specify only a handful of them that would actually be used.

Unfortunately, I didn't find an elaborate way to do so without modifying lib's own files (providers.json), which is a bad practice. I tried setting providers manually in my codebase, but didn't figure out how to pass them to my Wallet instance, given that init doesn't accept those. Neither did I succeeded in setting providers when manually assigning wallet.providers.
I don't have access to that code right now as it was terminated during refactoring and attempts to fix the process, and wasn't committed to system control version, but I could try to reproduce mock example of that code upon such a request to clarify the steps I took.

I would much appreciate if someone already faced this issue and would be glad to present their solution. Thanks in advance

Actually the best way to do this is to change the providers.json file in the .bitcoinlib directory. So not in the library code itself but in the settings directory. You can remove providers from providers.json or disable them by setting the proirity to 0.

You can alse specify providers after creating a Wallet object:

w = wallet_create_or_open("mywalletfullofcoins") w.providers = ['electrumx'] 

Now only the ElectrumX provider is used.
