Hey thanks for posting this and for the detailed write-up. The implementation looks like solid work.
The stealth address space has seen a lot of development since Vitalik’s original post. Umbra (whose team co-authored EIP-5564) is live on mainnet with 85K+ transactions, and Fluidkey was recently featured on the ENS blog with native ENS subdomain integration and a full wallet experience. For a new proposal in this space to clear the bar, we’d need to see clear differentiation from what already exists and is funded.
None of this takes away from the quality of the build itself. Let’s get the prior grant squared away and we’re happy to look at future proposals with fresh eyes.
