RPCs not compliant with the JSON-RPC spec

Dear Polkadex Team,

I hope this message finds you well. My name is Josep, and I'm the technical lead of the Polkadot-API (PAPI) team.

In case you're not familiar with Polkadot-API, it's a modern library designed to replace PolkadotJS, built on top of a properly specified and standardized JSON-RPC API for Polkadot-based networks. The modern JSON-RPC APIs offer many advantages over the legacy ones; you can read more about it here and here.

We've noticed that there are no available public Polkadex RPCs that expose the modern JSON-RPC API. Also, I wasn't able to test if your chain works using the light-client provider because it seems that your chainspecs are outdated 😞.

Our team has developed a middleware solution to ensure that Polkadot-API can function seamlessly with chains running older versions of the Polkadot-SDK node. Unfortunately, it appears that the RPC providers for Polkadex are using an even older version, which the middleware does not support.

We kindly request that you consider working with your RPC providers to upgrade the PolkadotSDK node to a more modern version that supports the new JSON-RPC API. This upgrade would enable DApp developers to easily interact with your chain using PAPI, unlocking benefits such as improved performance, reduced resource usage, out-of-the-box strong type generation for your chain, and the ability for developers to handle runtime upgrades on the fly.

Thank you for your time and consideration.

Best regards,

Josep
