Build a Solana token launch transaction
sol_build_launch_tx$0.02 per call. Returns a complete, unsigned Solana transaction that creates an SPL mint, writes Metaplex metadata on-chain, mints the supply to the payer and revokes the mint authority in the same transaction. NON-CUSTODIAL: the service never sees a private key — the caller signs with their own wallet. Requires a payer public key. Test on devnet first.
