  • METAPLEX_AGENT_NETWORKDefault cluster: mainnet or devnet. Defaults to mainnet; every tool also takes a per-call network.
  • REQUIRE_CONFIRMRefuse to broadcast a mint or registration until the call is re-issued with confirm=true. Default true.
  • DEPLOY_FEE_SOLMainnet deploy fee, in SOL, paid to DEPLOY_FEE_WALLET in the same transaction as the mint. Default 0.02.
  • DEPLOY_FEE_ENABLEDSet 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.
