Raycash Private Beta is live and we shipped to Sepolia, US sheriffs stepped back from the CLARITY Act fight, Ethereum researchers worked out how much gas a private transaction actually needs, and World open-sourced its identity-proving toolkit.
In House
Some updates on what happened at Raycash this week:
Raycash Private Beta opened last week. Two hundred people are in the app right now, poking at every corner of it, and their feedback has been monumental in improving the experience so far.
If you want to see confidential balances and transfers running for real, this is the first place to do it.
Beta access is still opening up in waves. Join the waitlist at raycash.xyz →
On Our Radar
Here is what got us excited this week:
National Sheriffs’ Association drops opposition to the CLARITY Act
The National Sheriffs’ Association had opposed the CLARITY Act since May, warning that Section 604, the provision shielding non-custodial developers from money-transmitter liability, would give mixers and DeFi platforms a blanket exemption from AML rules. On September 3, the association changed its position to neutral. A Senate cloture vote is scheduled for September 15 and needs 60 votes. Republicans hold 53 seats.
Section 604 protects code, not custody. Treating that as automatically dangerous was always the weaker argument, and it is notable that the group making it has now stepped back. The real obstacle left is unrelated to law enforcement: unresolved questions about how to limit a sitting president’s ability to profit from digital assets.
Optimism publishes framework mapping the onchain privacy tradeoff space
Optimism lays out six evaluation axes (what is hidden, usability, cost, regulatory compliance, maturity, ecosystem) across privacy architectures from consortium networks to private validiums, citing ERC-7984 (same framework used by Raycash) and its own Privacy Boost SDK, live on OP Mainnet since April 2026 and sanctions-screened via TRM Labs. A useful competitive map of how the market is segmenting privacy-by-design choices, and a direct reference point for where Raycash sits on that spectrum.
World open-sources ProveKit
World has open-sourced ProveKit, the zero-knowledge identity toolkit that has been running inside World ID since April. It lets someone prove a claim, such as age or valid ID ownership, without revealing the document behind it, and runs entirely on the user’s own device. The release is MIT-licensed and lands days after reports of a major driver’s license data leak.
A company with World’s user base putting real engineering behind on-device proofs is a meaningful signal for the rest of the industry. It suggests the next wave of adoption comes from whoever makes the unglamorous parts of this actually work, not from another paper.
Thanks,
From the Raycash team
