This issue should handle:

1. docs: update grove endpoint offerings #1743
2. feature request: document kingsuper bridge node snapshot #1465
3. feature request: document polkachu snapshot #1598
4. and also make a page in docs with paid RPC services that people can use and historical data providers

[jcstein]

5. docs: document kyve historical data #1755

adding from previous issue: feature request: make an issue template for adding new RPCs

https://docs.github.com/en/communities/using-templates-to-encourage-useful-issues-and-pull-requests/configuring-issue-templates-for-your-repository

this would include

• type of endpoint
• open ports
• verification that it works
• etc...

RPCs that work for light nodes that are reliable:

Mainnet Beta

Endpoint	Status
rpc.celestia.pops.one	operational
public-celestia-consensus.numia.xyz	operational
consensus.lunaroasis.net	operational
celestia.port-routing.lava.build	WIP
