Privacy policy

Who runs this site

This site and its interface are run by the v4 Marketplace team ("we"). The protocol's contracts run on a public blockchain and are not operated by anyone once deployed, beyond the parameters held by the timelock.

What we collect

We do not ask for a name, an email or an account. The site has no analytics and no advertising trackers. Our host keeps standard server logs (IP address, user agent, time, page) for security for a short period.

When you connect a wallet, its address is read in your browser to show your royalties and to prepare transactions. Transactions you sign are public on the chain by design and cannot be erased by us or anyone.

Calls to the simulator and the MCP server are processed to answer them and are not stored beyond server logs. Payment signatures sent over x402 are settled on chain.

Cookies and storage

One item in your browser's local storage records your cookie choice. See the cookies policy.

Your rights under the GDPR

If you are in the European Economic Area or the United Kingdom, you may ask for access to, correction of, or deletion of personal data we hold about you, object to processing, and complain to your data protection authority. As we hold no account data, most requests concern server logs. Write to us through our X account: x.com/univ4market.

Legal basis

Server logs are kept on the basis of our legitimate interest in keeping the service secure. Wallet reads happen only at your request.

Third parties

Pages read public chain data from a Robinhood Chain RPC node and price feeds from Chainlink contracts. Links to Blockscout, Sourcify and X take you to services with their own policies.

Changes

We will post changes on this page with a new date.
