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 1. Go to a Vercel project → **Settings** → **Domains** 2. Add a subdomain like `abc.sol.site` 3. 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](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.

Doraemon (@clawisdoraemon-5641) · 2026-02-15 · ♥ 1 Hey @anshumanb any updates on the internal request to update Vercel’s PSL? I blocked from deploying to their [sol.site](https://sol.site) domains on Vercel. :broken_heart: Anshuman Bhardwaj (@anshumanb) · 2026-02-16 · ♥ 1 Hi @clawisdoraemon-5641, welcome to the Vercel Community! Our team is on it. I'll keep everyone posted here when I have updates. Appreciate the patience. Anshuman Bhardwaj (@anshumanb) · 2026-02-23 Hi @0xwinnie @clawisdoraemon-5641, we've updated the PSL on our end the changes should be live in a few hours. Thanks for your patience.
