It is a library only? A wallet (like Metamask) isn’t part of the grant?
Personally, I am not keen on proposals that don’t have a user facing app.


Can we have a roundup and accounting on all the web/wasm attempts at a Zcash wallet? This is an idea that I have always liked but several people have thrown some hours at the problem without a ringing success (even I). What exactly happened with these efforts and what are the current statuses?

FYI for anyone who missed the chainsafe research phase Zcash SDK Implementation [JS/TS] - Proposal - #49 by ec2


Hey! For full transparency our v1 of this proposal actually included the following as part of Milestone 5:
"Implement simple PoC wallet page using API

Upon running the proposal by the foundation it was suggested that we attempt to reduce the scope so as to bring the overall cost of the project down, without limiting the outcome of the project.

With this in mind, we reduced the cost significantly (as highlighted in the cost breakdown here: WebZjs Grant Application Breakdown - Google Docs )

In light of our completed feasibility study (see above) and pending further feedback from the foundation and community, should it be decided that the PoC is still essential in getting this passed, ChainSafe will be willing to support this request.

I hope that this helps!! :slight_smile:

Well, I wasn’t referring to a PoC but a full fledged wallet.

Anyway, it is up to the committee to decide.

In my opinion, this is a step forward.


Does the link to the research phase address this concern @skyl ? If not, cc’ing my colleague @Wollum-ChainSafe in here should he have anything more to add. :slight_smile:

I’m not referencing chainsafe or these efforts directly but there were more efforts historically. I think “Zephyr” was one … I think there were more … I can maybe look more closely later but chatgpt found a few things.
