The Balancer Flipcause page is inactive and we decided to accept donations via GitHub Sponsors

We can add up to four GitHub Sponsors to the Balancer GitHub repo:

Hi, I'd like to take this issue if it's still needed.

@amahuli03 It's still needed! Thank you for picking it up -- Let me know if you need more info about it

@sahilds1 I'm getting this done now and want to double-check before opening a PR--you want every "donate" button to link to the balancer-main github repo?

Out of curiosity, could you share the intention behind this change? I’m not seeing any donation info or flow on the repo and want to clarify what this fix should achieve.

@amahuli03 Thanks for your question! I filled in the description of this ticket with information about its intention

I think the flow would be clearer if we changed the name of the button from "Donate" to "Support Development" and that would encompass not only financial support (sponsoring) but also code contributions. Thoughts?
