Zcash Integration for the Open Wallet Standard

Approved

Integrates Zcash into the newly launched Open Wallet Standard (backed by PayPal, Circle, Ripple, Solana/Ethereum Foundations) via ZIP-32 key derivation and PCZT spend authorization for Sapling and Orchard, making Zcash the first privacy chain in the standard. Cryptography complete; integration work only. Requesting $25,000 . Gguy: I think that this applicant has been able to prove themselves over a small period of time and I’m excited to fund this. Artkor: While open wallets are still a relatively new initiative it already supports a range of major blockchain ecosystems through a unified interface, which gives it a meaningful potential for broader adoption. The applicant has also shown a high level of energy and consistent engagement. I approve this proposal. Zerodartz: The standard might be early but it’s a strong applicant and I support them as they have shown they can get stuff done and are actively pushing to have Zcash payments in more places. I approve. Hanh: It’s a fairly simple standard so even if it doesn’t work out the code base will be reusable for other purposes. Not much risk here. I approve. Decentralistdan: strong applicant who has proven they can deliver.
