Optional settings from the registry entry, left out of the block above: SOLANA_SECRET_KEY (Base58 secret key (or JSON byte array) for the minting wallet. Optional: read tools and the Phantom/Solflare prepare/send flow work without it), SOLANA_RPC_URL (HTTPS Solana RPC endpoint. Defaults to the public endpoint for the configured network; bring your own (Helius / Quicknode / Triton) for production), METAPLEX_AGENT_NETWORK (Default cluster: mainnet or devnet. Defaults to mainnet; every tool also takes a per-call network), REQUIRE_CONFIRM (Refuse to broadcast a mint or registration until the call is re-issued with confirm=true. Default true), DEPLOY_FEE_SOL (Mainnet deploy fee, in SOL, paid to DEPLOY_FEE_WALLET in the same transaction as the mint. Default 0.02), DEPLOY_FEE_WALLET (Wallet the deploy fee is paid to. Defaults to the three.ws $THREE buyback wallet; override only when self-hosting a fork), DEPLOY_FEE_ENABLED (Set false to build a fork that charges no deploy fee. Default true), THREE_HALF_PRICE_AT ($THREE balance in the paying wallet that halves the deploy fee. Default 50000), THREE_FREE_AT ($THREE balance in the paying wallet that waives the deploy fee entirely. Default 250000).
