This matches Polymarket's builder-volume convention over the same CLOB V2 history without importing Polymarket's leaderboard totals or pre-V2 attribution. What's new: * `GET /v3/builders` and `GET /v3/builders/{code}` add `volume`, `buy_volume`, and `sell_volume` aliases. * `volume_scope=clob_v2_onchain` and `volume_semantics=outcome_share_par_notional` make the coverage and unit explicit. * Existing fill count, fees, raw maker/taker totals, timestamps, profile metadata, and compatibility fields remain available. * `sort=volume` uses only Polynode's local builder aggregate. Public Polymarket volume is not used as a fallback or ranking input. Docs: [Builder Leaderboard](/data/builders/list) and [Builder Detail](/data/builders/detail) *** ## 2026-08-18 - Query sports games by event or market ID Sports game endpoints can now be queried by Polymarket event ID or market ID. What's new: * Use `/v2/sports/games/by-event/{event_id}` for an event ID. * Use `/v2/sports/games/by-market/{market_id}` for a market ID. The response contains the full parent event and its canonical event slug. * Append `/state`, `/context`, `/prices`, or `/history` to either identifier route for the corresponding game data. * Existing slug-based routes are unchanged. Docs: [Game Detail](/api-reference/sports/game-detail) *** ## 2026-08-18 - Connect Wallet to user-owned V2 orders The TypeScript, Python, and Rust SDKs now provide one documented platform flow from wallet connection through an actual zero-attribution user-owned V2 order. What's new: * TypeScript `polynode-sdk` 0.14.2 provides a browser-memory session, standard viem provider typing, wallet-confirmed USDC.e to pUSD funding, exact order preview/signing, a durable pre-submit order-hash callback, and authenticated open-order reconciliation. * TypeScript 0.14.2, Python `polynode` 0.14.1, and Rust `polynode` 0.17.1 share one browser-safe signing-request and encrypted backend-vault bundle contract. Prepared orders expose the canonical exchange order hash before transport so open orders and fills can be reconciled by exact identity instead of an amount/time heuristic. * Platforms can authorize each connected wallet once, retain wallet-scoped credentials in an encrypted vault, prepare one short-lived order on any worker, send only typed data to the browser, and consume submission state exactly once. * User-owned orders contain zero builder attribution and do not consume a platform's shared builder allowance. Market rules, collateral, API rate limits, and ordinary service limits still apply. * The default fresh deposit-wallet path requires three setup signatures: one ownership message, one EIP-712 approval batch containing all four base-order permissions, and one EIP-712 `ClobAuth` signature. Wallet deployment itself does not require a signature. * A first order therefore requires four total signatures when pUSD is already funded, or five when an SDK-confirmed USDC.e to pUSD conversion is also needed. A returning wallet restored from the encrypted vault has no setup signatures and signs only the exact order. * The guide covers credential sensitivity, account and chain binding, ownership-conditional atomic storage, exception-safe cleanup, minimal dependency installs, and conservative ambiguous-submit reconciliation.

What's improved: * The confirmed-trade payload, receipt-derived values, order hashes, deduplication, and status ordering are unchanged. * A release investigation reproduced 10 to 28-second confirmed-trade delays while status delivery remained current. The corrected path removed that accumulated delay. * The first complete post-release comparison covered 1,886 confirmed trades. Observed delivery measured 246.7 milliseconds ahead at the median, 318.2 milliseconds behind at p90, and 492.4 milliseconds behind at p99. * A separate acceptance window covered 13 consecutive Polygon heads, 340 settlements, and 178 status updates with no gaps, duplicates, reversals, or parse errors. No subscription or parser change is required.
