Privacy policy
Last updated 6 October 2026.
The operator of this site is Mikhail Kartavchenko, New York, NY, United States. Contact about privacy: mk5303@columbia.edu.
1. The short version
This site has no accounts, no analytics, no advertising and no tracking pixels, and it sets no cookies. The only form is the application form for protocols, described in section 5. Apart from that, the only personal data involved is what any website visit and any blockchain transaction necessarily expose, described below.
2. What the site itself stores
Three small values are kept in your browser: one records that you accepted the notice in the app (deleted when you close the tab), one records which wallet addresses have already added the USC network, so the setup is not offered twice, and one keeps a copy of the public chain activity already read for a connected wallet, so it is not read again. None of them ever leaves your device. Details are on the cookies and storage page.
3. Who else sees your requests
- Cloudflare hosts the site and the public endpoints. Like any host it receives your IP address, browser details and the pages you request, and may keep them in logs for security and operations. See Cloudflare's privacy policy.
- rpc.usc.money and status.usc.money are run by the operator through Cloudflare. They receive the blockchain reads your browser makes, which can include your wallet address. The operator does not log these requests for any purpose other than keeping the service running.
- PublicNode (ethereum-sepolia-rpc.publicnode.com) answers the site's read requests for Sepolia, which can include your wallet address.
- Your wallet (for example MetaMask or Rabby) and the RPC provider it is set to use see every transaction you sign. Their own privacy policies apply.
The site loads no fonts, scripts or images from other companies. Its code library (ethers.js) is served from this site.
4. What is public forever
Any transaction you sign is recorded permanently on a public blockchain, with your wallet address, amounts and times. Anyone can read it, and nobody, including the operator, can delete it. Do not put personal information in any transaction field.
5. Email and the protocol application form
If you email the operator, the message and your address are used only to reply and are not shared.
If a protocol applies for a line on the protocols page, what the form contains (protocol name, website, contact email, the details given) is stored with Cloudflare, with the time and the country the request came from, and is used only to assess and answer the application. To limit abuse, the sender's IP address is kept for one hour. Ask at the address below to have an application deleted.
6. Your rights
Depending on where you live, you may have rights to access, correct or delete personal data held about you. Because this site holds nothing beyond the hosting logs and any application described above, most requests can be answered quickly. Write to mk5303@columbia.edu. On-chain data cannot be deleted by anyone.
7. Children
The site is not intended for anyone under 18.
8. Changes
If this policy changes, the date at the top will change. A material change, such as adding analytics, would be announced on the home page first.
