This one needs environment variables set before it will start: OWNER_SECRET_KEY (Owner 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_NETWORK (Cluster: mainnet or devnet. Defaults to mainnet. State is kept per network, so a devnet rehearsal never touches mainnet agents.), SOLANA_RPC_URL (HTTPS Solana RPC endpoint. Defaults to the public endpoint for the configured network; bring your own (Helius / Quicknode / Triton) for production.), OAW_STATE_DIR (Where agent keypairs, guardrails, and the spend ledger are stored. Defaults to ~/.onchain-agent-wallets, written 0600 inside a 0700 directory.), REQUIRE_CONFIRM (Refuse to broadcast anything that moves value until the call is re-issued with confirm:true. Default true.). The author declared them in the registry entry; get the values from the project itself.
