This one needs environment variables set before it will start: BILLBOARD_KEYPAIR (Base58 secret key, or path to a Solana CLI JSON keypair file. Unset = read-only mode: reads and dry runs work, nothing can be signed.), MAX_BID_SOL (Largest single bid the server will sign, in SOL. Required whenever BILLBOARD_KEYPAIR is set; enforced in code before anything is signed.), DAILY_CAP_SOL (Total gross bids allowed per rolling 24 hours, in SOL. Defaults to MAX_BID_SOL. Refunds do not restore the allowance.), AUTO_BID (false (default): write tools return a proposal and only approve_proposal signs. true: write tools sign directly, still inside the limits.), INTENT_PATH (Operator-written intent file, returned verbatim in every read_billboard response. A missing file is not an error.), HISTORY_URL (Optional URL of a site-published history.json. Unset, unreachable or disagreeing with the chain = flip history derived on-chain.), RPC_URL (Solana JSON-RPC endpoint.), RPC_WS_URL (Websocket endpoint for account-change subscriptions. Defaults to RPC_URL with https replaced by wss.), ACTIVITY_LOG_PATH (Append-only JSONL log of every proposal, approval, refusal and transaction, each with the agent's reasoning.). The author declared them in the registry entry; get the values from the project itself.
