Request for Support: ed25519 Curve and Account Index Support

[Jiaweeee]

Hi Web3Auth Team,

I’m working with Web3Auth and have a question regarding the support for account index with the ed25519 curve. I would appreciate clarification on the following:

1. Why does the ed25519 curve not support account index?
   Is this due to technical limitations or is it something that hasn't been implemented yet?

2. Is there a plan to implement this feature in the near future?
   If it's possible to support account index, when might this feature be available?

3. If there are no immediate plans to support this, we are considering implementing it ourselves. Any guidance or support you could provide would be much appreciated, especially in terms of best practices or collaboration opportunities.

Looking forward to your response.

Thanks!
