[feature request] open source the server spec and allow custom server implementations

[brendanjryan]

Hello!

Is there any interest on the part of the Coinbase team to open source an example implementation of the WalletLink server or at least provide an implementation spec? This can somewhat be derived form the server/client messages [0] but is not readily evident.

I believe that this would further increase adoption and would benefit this project by:

1. Improving security: By allowing large users to "bring their own server" with their own security controls.
2. Increasing transparency: By allowing app developers / users to easily grok the security behind this critical protocol. See prior art for WalletConnect [0].
3. Foster innovation: Allowing other companies and individuals to contribute back to the server spec (count me in here!)

@brendanjryan you can browse the server code here -> https://github.com/coinbase/coinbase-wallet-sdk/tree/f1de7016fa471514c8de979c421a30fd2ae8b5a5/server

And the protocol is designed such that you can swap in any server implementation via the WALLETLINK_URL environment variable when building walletlink

ack thanks for the flag @brendanww !

In this case, while this package is very useful (🙇) I was specifically interested in seeing if there was interest in an open spec / reference implementation beyond what is in that package. If so, I would be happy to donate on as well!

Yes, an open spec and reference implementation of the server is something we're interested in providing. I don't have any details to share now but I will leave this thread open to share updates and continue the discussion. Thanks for making the case for this addition.
