Solana mint authority check
Paste a Solana mint and see whether mintAuthority and freezeAuthority are both revoked.
Result
What PASS means
PASS only when parsed mintAuthority and freezeAuthority are both JSON null. The call is getAccountInfo with jsonParsed. https://api.mainnet-beta.solana.com often returns HTTP 403 to browsers, so the box defaults to a CORS-friendly public RPC. Token-2022 extensions are not part of this verdict.
