Notes:
The only other design brief I see is some unfinished Elemental ZEC UI work (https://elementalzcash.com/react/getting-started/), so this wouldn’t be duplicate work. I would reach out to communicate regardless and hopefully dovetail with their components. Elemental ZEC – UI Component Kit and Payment Processor - #27 by 1337bytes
Work would need to keep the Zcash UniFFI Library in consideration as requested by Adi/Pacu. RFP - Zcash UniFFI Library
Request to communicate with and include ZGo by @earthrise added
