Current Behavior
When users try to add a subdomain under sol.site (e.g., abc.sol.site) to their Vercel project, they get the error:
Error: This domain is linked to another Vercel account. To use it with this project, add a TXT record at _vercel.sol.site to verify ownership.
Users are asked to verify at _vercel.sol.site, which they don’t have access to — because they only own the subdomain, not the root domain.
Expected Behavior
Vercel should recognize sol.site as a public suffix (like github.io or netlify.app) and allow each subdomain (e.g., abc.sol.site) to be added independently without root domain verification.
Steps to Reproduce
- Go to a Vercel project → Settings → Domains
- Add a subdomain like
abc.sol.site - Vercel shows “Verification Needed” and requires a TXT record at
_vercel.sol.site
sol.site is already listed in the official Public Suffix List:
https://github.com/publicsuffix/list/blob/main/public_suffix_list.dat
It appears Vercel’s internal PSL copy has not yet been updated to reflect this.
Project Information
sol.site is operated by SNS (Solana Name Service), a Web3 naming platform on the Solana blockchain. We issue .sol.site subdomains to independent, mutually-untrusting users — the exact use case the PSL was designed for. Our domain has been reviewed and merged into the PSL.
We kindly request that Vercel refresh its internal PSL so sol.site is properly recognized. Thank you!
