This is the public release log for the Poly Syncer Polymarket copy trading platform. We ship continuously; the entries below capture user-visible changes to our automated Polymarket trading stack — internal refactors and infrastructure migrations land silently. Newest releases are at the top. Tags map to: feat (new capability), fix (bug correction), perf (latency or throughput), security (hardening or patch). For breaking API changes, see the deprecation lane in the API reference.
v2.7.0 — May 5, 2026
tags: feat · perf
- feat — Visual no-code strategy builder ships to all Elite accounts. Drag-and-drop wallet screens, Kelly sizers, category gates, and exit rules onto a canvas; preview a 90-day backtest before activation. See the strategies page.
- feat — Per-strategy bankroll segmentation: each strategy now operates on its own allocated balance, so a drawdown in one cannot cascade into another.
- perf — Leaderboard re-rank cycle reduced from 90s to 60s; aggregator memory footprint down ~38% after switching the rolling-window structure to a packed circular buffer.
- feat — Treemap view of category allocation in the portfolio dashboard; click any cell to scope the entire view.
- deprecation — Retired the legacy 7-day trial signup in favour of a permanent free view-only tier. Existing trial accounts run to their original expiry; new sign-ups go straight to free, with Pro and Elite available on the billing page.
v2.6.2 — April 14, 2026
tags: security · fix
- security — Trail of Bits Q1 2026 audit closed with zero high-severity findings. Two informational notes addressed: tighter EIP-712 typed-data domain separation and stricter timestamp window on signed WebSocket subscribes (now 30s, was 60s).
- fix — Resolved a rare race where a fast unfollow followed by re-follow in the same 60-second leaderboard cycle could miss the next signal. Added a deterministic re-subscribe step.
- fix — Daily PnL chart correctly attributes overnight resolution payouts to the resolution day rather than the entry day.
- security — Rotated all internal service-to-service mTLS certificates after a routine 90-day cycle.
v2.6.0 — March 22, 2026
tags: feat · perf
- feat — Public REST + WebSocket API graduated from beta. Pro plans get a 64-byte API key with 60 req/min; Elite gets the raw signal feed via EIP-712 signed subscribe at 600 req/min. Full reference on the API page.
- feat — Two new pre-built strategies: Earnings binary spread and Whale-watcher copy. Both ship to Pro and Elite.
- perf — Mirror latency p99 reduced from 1,800ms to 940ms after deploying the Frankfurt and Singapore co-located validator nodes.
- feat — CSV and JSON export endpoints for the portfolio. Generates a 24-hour signed URL; canonical against the live ledger.
v2.5.1 — February 18, 2026
tags: fix · perf
- fix — Slippage guard threshold was being computed against the signal-time mid rather than the signal-time best-ask for buy fills; corrected. Affected an estimated 0.3% of fills, all over-rejected (no incorrect executions).
- perf — Reduced WebSocket frame size on
signals.rawby ~22% via field-name dictionary compression. No client changes required. - fix — Category treemap rendered an empty cell for markets tagged Trending only; treemap now folds Trending into the underlying primary category.
v2.5.0 — January 28, 2026
tags: feat · security
- feat — Server-side risk controls (stop-loss, take-profit, max-drawdown circuit breaker) now persist independently of the panel session. Triggers fire whether or not the panel is open.
- feat — Per-trader divergence column in the portfolio: live comparison of a followed wallet’s historical Sharpe against your realized Sharpe from following them.
- security — Rolled out scoped trading signatures with per-strategy allowlists. A signature for Strategy A cannot be replayed by Strategy B even if both run on the same wallet.
- feat — Half-Kelly default on all new strategies. Existing strategies untouched; opt-in upgrade available from the panel.
v2.4.0 — January 6, 2026
tags: feat · perf
- feat — Z-score outlier filter applied to leaderboard composite score; lucky single-trade prints no longer inflate rank. Profile pages still show full history.
- feat — Category-filtered leaderboard view across all 25 Polymarket categories. Filter persists across sessions per wallet.
- perf — Listener pipeline migrated from a polling head-of-chain loop to push-based subscription on Polygon; head-detection latency cut from ~1,200ms to ~140ms.
v2.3.0 — December 12, 2025
tags: feat · security
- feat — Flashbots-style private mempool routing enabled by default for all paid plans. Reduces front-run exposure on large copy fills.
- feat — Trailing-stop exit rule added to the strategy builder; configurable in basis points of the YES probability.
- security — One-click revocation of any active trading signature directly from the panel header. Confirmation lands on-chain in <5 seconds.
- feat — Weekly summary email (opt-in, off by default — privacy-first). Sends realized PnL, top contributors, and category mix.
v2.2.0 — December 1, 2025
tags: feat
- feat — Public launch of the Poly Syncer leaderboard. 90-day rolling window, seven primary metrics, refreshed every 90 seconds.
- feat — Three pre-built strategies at launch: Top-10 weighted basket, Politics-only conviction, and Sports same-side fade.
- feat — 7-day free trial available without email or KYC. Connect a wallet, choose a wallet to mirror, set risk, trade.
