Smeltr: The non-custodial Token-2022 launcher for Solana

Hey Product Hunt! 👋 I'm Josh Kinsolving, the builder behind Smeltr. Why I built this: I kept running into the same problem deploying Token-2022 tokens for projects: either I was writing the same boilerplate transaction construction code from scratch, or I was using a launcher that held my mint authority in some opaque way I couldn't verify. Smeltr solves both. It handles the transaction construction — correct instruction ordering, compatibility validation, rent calculation — and the source code literally throws an exception if any platform address appears in a token authority slot. Not a terms of service. An exception. What makes it different from other launchers: Truly non-custodial — verified at the code level, not just the policy level Token-2022 extension support — transfer fees, non-transferable (soul-bound), permanent delegate — with compatibility checking between them Correct metadata pattern — we overfund the account in transaction 1 to cover the Token Metadata TLV. Most third-party implementations get this wrong and require a separate reallocate transaction (or just fail) No account required — connect your wallet, deploy, disconnect. Done. Who it's for: Solana developers who are tired of writing the same deployment boilerplate Founders who want to launch a token without hiring a Solana dev Anyone deploying a loyalty credential, game currency, or creator royalty token who wants Token-2022 extension features Happy to answer any questions about the technical implementation, the non-custodial architecture, or Token-2022 in general— ask me anything.
