**Grant amendment update**

Greetings, fellow Zcashers!

As our project grew, we built infrastructure needed to operate ZcashMe and ZcashNames and released components that can be useful outside our own applications.

So we’re updating our retrospective grant to include work that fell outside the original submission and was not covered by our recent Zcash Community Grant (still uncollected).

We did not increase the requested amount.

Here are the additions:

1. We built seer-sync, a standalone Rust chain-sync engine for applications that need to observe Zcash activity without implementing a wallet stack. [crates.io: Rust Package Registry](https://crates.io/crates/seer-sync)

2. We built a service that watches Zcash activity for multiple configured viewing keys and writes both mempool and confirmed transactions into Postgres automatically. [GitHub - zcashme/zns-mempool · GitHub](https://github.com/zcashme/zns-mempool)

3. We built **zebra-indexer-proto** , a Rust crate containing bindings for Zebra’s indexer gRPC interface. [crates.io: Rust Package Registry](https://crates.io/crates/zebra-indexer-proto)

4. We built a “Sign in with Zcash” flow using OAuth2/OpenID Connect. [GitHub - zcashme/zns-login: Zcash-based authentication: pay to log in · GitHub](https://github.com/zcashme/zns-login)

Together, this work reduces several barriers to building on Zcash. So thank you to everyone who supports ZcashMe and ZcashNames. It is an honor to contribute to the ecosystem.

By the way, did you know: since the original application, our waitlist crossed **9,000 names** , and Barry Silbert and WallStreetBets both mentioned the project!

Special thanks to everyone who tests ZcashMe and ZcashNames, shares them, contributes code and gives us feedback along the way. We’re making privacy as normal as names.

ZM ZN,  
Julian & Team
