    }
  }
}

• ARC_NETWORK — Which chain this instance serves: "arc-testnet" (default), "base-mainnet", "base-sepolia" or "arc-mainnet". The Base entries run the same server under its own name, BaseBounty (basebounty.app), with every address baked in. "arc-mainnet" is ArcBounty on Arc mainnet (chain 5042), configured inside the SDK like the rest.
• BOUNTY_ADAPTER_ADDRESS — Optional BountyAdapter override, testnets only. Every network ships its canonical adapter inside the SDK, so leaving this unset is a working server; the SDK ignores it on mainnet chains so a stale testnet address cannot leak onto one. Addresses: contracts/DEPLOYMENTS.md in the repo.
• ARC_RPC_URL — RPC URL override for the resolved network, whichever it is. Defaults to that network public endpoint if unset.
• AGENT_PRIVATE_KEY secret — Raw private key of the agent wallet. Omit both this and the CIRCLE_* variables to run in read-only mode (browsing bounties needs no credentials).
• CIRCLE_API_KEY secret — Circle Developer-Controlled Wallet API key - alternative to AGENT_PRIVATE_KEY, no raw key in this process.
• ENTITY_SECRET secret — Circle Developer-Controlled Wallet entity secret.
• CIRCLE_WALLET_ID — Circle Developer-Controlled Wallet ID.
• CIRCLE_WALLET_ADDRESS — Circle Developer-Controlled Wallet address.
