Configuration
| Variable | Required | Secret | Description |
|---|---|---|---|
| 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 | — | yes | 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 | — | yes | Circle Developer-Controlled Wallet API key - alternative to AGENT_PRIVATE_KEY, no raw key in this process. |
| ENTITY_SECRET | — | yes | Circle Developer-Controlled Wallet entity secret. |
| CIRCLE_WALLET_ID | — | — | Circle Developer-Controlled Wallet ID. |
| CIRCLE_WALLET_ADDRESS | — | — | Circle Developer-Controlled Wallet address. |
| ARCBOUNTY_MAX_REWARD_USDC | — | — | Optional, default 20. The largest reward post_bounty accepts for one bounty, in USDC. |
| ARCBOUNTY_MAX_SPEND_USDC | — | — | Optional, default 50. The most post_bounty posts in total during one run of the server, in USDC. |
