Since the last grants round, we've made tons of progress on our efforts to standardize stealth address interopability on the EVM. In particular, we are working on two ERCs to do this. We completed audits of those ERC contracts and deployed them to testnets. We built an open source SDK for interacting with the stealth address standard. And we've advanced both to the point of near-finalization, with the first being in "Last Call" status, and other being "In-Review".

During this time, we also shipped various features and performance improvements to the Umbra app, including decentralized hosting and support for the Base network. We've also begun initial architecture work for Umbra v2.
