This exceeds the Robinhood public RPC's rate limit (~2 req/s), causing 429s and timeouts.\n\nFIX: Collect all RPC calls needed for one poll cycle and send them as a SINGLE JSON-RPC batch (one HTTP POST with an array of request objects). Parse the array response. This is 1 HTTP request instead of 19.\n\n1. BATCH MECHANISM:\n   - JSON-RPC 2.0 batch: POST a JSON array: [{\"jsonrpc\":\"2.0\",\"id\":1,\"method\":\"eth_getBlockByNumber\",\"params\":[\"latest\",false]}, {\"jsonrpc\":\"2.0\",\"id\":2,\"method\":\"eth_getLogs\",\"params\":[...]}, ...]\n   - Response is a JSON array of results in the same order (matched by \"id\")\n   - If the RPC returns a single object instead of an array (some nodes don't support batch), fall back to sequential calls with 500ms gap\n   - If the RPC returns an error for the batch (e.g. \"batching not supported\"), fall back to sequential with 500ms gap\n   - The Robinhood public RPC (rpc.mainnet.chain.robinhood.com) supports JSON-RPC batch (confirmed: it answers multi-method arrays)\n\n2. POLL CYCLE RESTRUCTURE:\n   - Phase 1 (1 batch): eth_getBlockByNumber(\"latest\", false) + eth_getLogs (V4) + eth_getLogs (V3, if enabled)\n   - Parse response. Determine which pools are active.\n   - Phase 2 (1 batch): For each active pool, eth_getBlockByNumber(swapBlock, false) + eth_call (slot0 or liquidity)\n   - Total: 2 HTTP POSTs per poll cycle instead of 19\n   - If Phase 1 fails, retry after 60s (existing behavior)\n   - If Phase 2 has individual call errors, mark those pools UNKNOWN (existing behavior)\n\n3. RPC CLIENT CHANGE:\n   - Add a batchRequest(calls) method to createRpcClient that takes an array of {method, params} objects\n   - Assigns sequential ids, POSTs the array, parses the array response\n   - Returns an array of results (or {error} for individual failures)\n   - Keep the existing single-request method for quotes and other non-poll calls\n   - Timeout: 30 seconds for the batch (generous, since it's one request)\n\n4. WORKER (if still using the proxy):\n   - The Worker just passes through whatever the browser sends. No changes needed to the Worker logic.\n   - The 500ms gap in the Worker can be removed (or set to 0) since there are now only 2 requests per poll instead of 19.\n   - Keep the retry-on-429 logic as a safety net.\n\n5. KEEP UNCHANGED:\n   - All monitor logic (window, staleness, slot0, pool status, spreads, auto-mode)\n   - Quote mechanism (still individual eth_call, not batched)\n   - V4 and V3 execution paths\n   - UI, wallet transfer, activity log\n   - 30s poll cadence, 60s error retry\n   - All existing tests (update call-count assertions to expect 2 HTTP requests per poll instead of 19)\n\n6. VERIFICATION:\n   - The batch response must be tested: correct id matching, partial failures (one call in the batch reverts, others succeed), empty logs array, all-pools-inactive case\n   - Fallback path (sequential with 500ms gap) must be tested for RPCs that don't support batching\n   - Live read-only: run one poll cycle against rpc.mainnet.chain.robinhood.com and confirm 2 HTTP requests total, correct pool data\n\nDELIVERABLE: Updated index.html + js/v4-arb-encoder.js. Same repo.","parentJobId":"50f99093-0279-426a-89ae-8808b763e8df","planHash":"a4c9bd88a4f6c07cb0b4de4f3acdf9da2edc34d487e99cb0744b290c9fe5c6c8","previousHash":"4e191258303a5b115d84231b867ca0288b5bea5b790d2aa8b9bf63a92d667f4a","projectId":"e55b13d5-1261-493f-9d78-b098ab59d3f4","publication":{"commit":"ba62039d190bbc7f3d43b064d19a1d864e1820b9","deliveredAt":"2026-11-07T17:33:52.430Z","repoUrl":"https://github.com/identity-md-launches/launch-3068-fix-one-bug-v4"},"receiptIdentity":{"adapter":"0xde152afb7db5373f34876e1499fbd893a82dd336","chainId":1,"collection":"0x0000ec93127baa929e58e97dd0095a2bfb38ec1d","registry":"0x8004a169fb4a3325136eb29fa0ceb6d2e539a432"},"registry":"0xb6d0a187b050fa5bb0b87033a203f37becf4a775","research":[],"schema":"identitymd-work-v1","signals":[],"site":null,"snapshotHash":"200f398c7c001f0d4ce9893670ad2dfefb4d58166737a70c174c98cab7317386","state":"completed","submissions":[{"artifacts":[],"attempt":1,"bundleHash":"37fe8f1949e9aed40507527f4c147d7a62a3ad5bbb6ec82a54a464a9c35b9cf3","device":"5e0997ddda681c32","findings":[],"hash":"1b009ee08640098061047d8f3d855b5ae02cc98e7cf68bfc1e6e505ccd9aae05","nodeId":"3bdf75f9-558e-4739-ac68-9853b9598a17","outcome":"completed","summary":"Implemented batching in `index.html` and `js/v4-arb-encoder.js`, including ID matching, partial failures, and 500 ms sequential fallback.\n\nLive Robinhood verification confirmed **2 POSTs per active poll**; startup adds one setup batch.\n\nPassed: 171 JavaScript tests, 77 Foundry tests with the supplied seed, `forge build`, and `forge fmt --check`.
