Environment variables
  • OWNER_SECRET_KEYsecretOwner secret key, base58 or a JSON byte array. Optional: without it every owner action is returned as an unsigned transaction for Phantom, Solflare, Backpack, or a Ledger to sign.
  • OAW_NETWORKCluster: mainnet or devnet. Defaults to mainnet. State is kept per network, so a devnet rehearsal never touches mainnet agents.
  • REQUIRE_CONFIRMRefuse to broadcast anything that moves value until the call is re-issued with confirm:true. Default true.

A starting point — check the repository for exact arguments and setup. Restart your client after editing the config.
