No email, no KYC, non-custodial. URL: https://mail.polysyncer.com Last updated: 2026-05-07 This file is the consolidated, machine-readable knowledge base for Poly Syncer. Every public-facing page is summarised below in Markdown with the canonical URL on the heading line. --- ## Homepage ([https://mail.polysyncer.com/](https://mail.polysyncer.com/)) Poly Syncer is the leading Polymarket copy trading platform. Connect a non-custodial wallet, pick wallets from the live leaderboard, and Poly Syncer mirrors their trades to your wallet in real time — typically within 600ms on Elite. There is no email signup, no KYC, no behavioural tracking. The site lists three plans: Free (view-only — browse leaderboard, inspect wallets, no copy trading), Pro ($299/month, 250 wallets, all 25 categories, premium dedicated RPC), and Elite ($499/month, unlimited wallets, sub-second co-located node, AI alpha discovery, hedge mode, mempool sniping). The homepage shows a top-wallets snapshot, an architecture diagram, an FAQ block, and live pricing data. Settlement is on Polygon; USDC is the unit of account. The mirror engine is written in Rust + Go and uses a Flashbots-style private mempool to defend against MEV. EIP-712 scoped trading permission is the custody model: keys never leave the user's wallet, permission is on-chain revocable in one block (~2 seconds on Polygon). Audited by Trail of Bits in Q1 2026 with no medium-or-higher findings. Free view-only tier; no credit card. --- ## About ([https://mail.polysyncer.com/about](https://mail.polysyncer.com/about)) Poly Syncer was founded in 2024 by an ex-MEV-searcher and a former HFT quant who watched friends lose money on Polymarket by chasing tweets. The core insight: prediction-market alpha is observable on-chain, but the median trader can't act on it fast enough or sized correctly. Poly Syncer productises that gap. The team is fully remote across UTC-5 to UTC+2. Core values: non-custodial by default, no surveillance (no email, no KYC, no analytics), refuse data brokerage, build for patient capital. Engineering is Rust-first for the hot path, Go for the listener, PHP for the public site, TypeScript for the dashboard. The company is independently funded — no VCs on the cap table — which the team cites as the reason it can refuse the standard data-monetisation playbook. --- ## Methodology ([https://mail.polysyncer.com/methodology](https://mail.polysyncer.com/methodology)) The composite wallet score is a weighted blend of Sharpe ratio (35%), ROI over the trailing 90 days (25%), win-rate adjusted for sample size via Wilson lower bound (20%), max drawdown penalty (10%), and category diversity (10%). Wallets with fewer than 30 settled trades are excluded. Outliers are filtered with a z-score cutoff of 2.5 against the population. Scores refresh every 60 seconds. Position sizing on copied trades uses capped fractional Kelly: f = min(0.25, edge/variance × 0.5). Backtests are walk-forward with a 30-day train / 7-day test split, no peeking. Slippage is modelled per-market using the actual book depth at the historical timestamp, not the midpoint. The methodology page documents every weight, every cutoff, and the open-source backtest harness. --- ## Leaderboard ([https://mail.polysyncer.com/leaderboard](https://mail.polysyncer.com/leaderboard)) Public ranking of every Polymarket wallet that meets the minimum-trades threshold. Default sort is composite score; also sortable by 30/90/365-day ROI, Sharpe, win-rate, total volume, and drawdown. Each row links to a wallet detail page showing trade history, category breakdown, equity curve, and a "copy" CTA. Refresh cadence: every 60 seconds. The board excludes wallets flagged as wash-trading or as exchange/treasury addresses. Filterable by 25 Polymarket categories (Politics, Sports, Crypto, Finance, Geopolitics, Earnings, Tech, Culture, World, Economy, Climate & Science, Elections, Mentions, Games, Basketball, NBA, Movies, Soccer, Weekly, Recurring, Fed Rates, Business, New Listing, Trending, Ending Soon). --- ## Strategies ([https://mail.polysyncer.com/strategies](https://mail.polysyncer.com/strategies)) Pre-built copy strategies that bundle multiple wallets and rules: Top-10 weighted basket (equal-risk weights across the top 10 by composite score), Politics conviction (only mirrors trades when source wallet is sized > 5% of NAV), Sports same-side fade (mirrors on opposite side when consensus is extreme), Earnings spread (calendar-aware, only active during earnings windows), Whale-watcher (filters for wallets > $1M cumulative volume). Elite plan unlocks a no-code strategy builder: combine wallet sets, category filters, size rules, time-of-day windows, and circuit breakers. Every strategy supports stop-loss, take-profit, and max-drawdown auto-pause. --- ## Portfolio ([https://mail.polysyncer.com/portfolio](https://mail.polysyncer.com/portfolio)) Live dashboard for the user's mirrored book. Shows open positions with mark-to-market PnL, realized PnL by day/week/month, attribution by source trader, allocation by category, and a daily equity curve. Risk controls: stop-loss (per position and portfolio-wide), take-profit, max drawdown circuit breaker (auto-pauses copying when breached). Export CSV for tax. WebSocket pushes position updates in real time. --- ## Developers / API ([https://mail.polysyncer.com/developers](https://mail.polysyncer.com/developers)) REST + WebSocket API. Pro plan: API-key auth, 60 requests/minute. Elite plan: EIP-712 signed-request auth, 600 requests/minute, plus raw signal feed (the same firehose the internal mirror engine consumes). Endpoints cover leaderboard, wallet detail, strategy CRUD, position management, and webhooks for trade events. WebSocket channels: `leaderboard.tick`, `wallet..trade`, `portfolio.update`. Idempotency keys on all mutating endpoints. Documented with OpenAPI 3.1. --- ## Glossary ([https://mail.polysyncer.com/glossary](https://mail.polysyncer.com/glossary)) Key terms: - **Polymarket**: USDC-settled prediction market on Polygon. Each market resolves to 0 or 1. - **Copy trading**: automated mirroring of one wallet's trades onto another wallet in real time. - **Composite score**: Poly Syncer's weighted blend of Sharpe, ROI, win-rate, drawdown, diversity. - **Sharpe ratio**: excess return divided by return volatility; measures risk-adjusted return. - **Fractional Kelly**: position-sizing rule that bets a fixed fraction of full Kelly to reduce drawdowns. - **MEV (maximal extractable value)**: profit a block builder can extract by reordering transactions. - **EIP-712**: Ethereum standard for typed-data signatures used for scoped trading permission. - **Non-custodial**: Poly Syncer never holds user funds; keys stay in the user's wallet. - **Slippage**: difference between expected and executed price; bigger on thin Polymarket books. - **Drawdown**: peak-to-trough decline in equity, measured as a percentage. --- ## FAQ ([https://mail.polysyncer.com/help](https://mail.polysyncer.com/help)) Common questions: "Do I need to give you my private key?" — No, EIP-712 grants scoped permission only. "What happens if Poly Syncer goes down?" — Your funds stay in your wallet; trading just pauses. "Can I revoke permission?" — Yes, in one block (~2s on Polygon). "How fast is the mirror?" — Pro: median ~2.5s, p99 ~6s. Elite: median ~600ms, p99 ~1.2s. "Do you support Safe multisig?" — Yes, via EIP-1271. "Refunds?" — 7-day money-back on Pro and Elite. "KYC?" — Never. "Tax reporting?" — CSV export and an API endpoint with cost-basis. "Restricted jurisdictions?" — OFAC, EU consolidated, UK HMT, UN; full list on the AML page. --- ## Whitepaper ([https://mail.polysyncer.com/whitepaper](https://mail.polysyncer.com/whitepaper)) Executive summary: Poly Syncer formalises copy-trading on a USDC prediction market as a constrained portfolio-replication problem. The whitepaper covers the listener architecture (Go, watching Polymarket's CLOB and on-chain settlement), the scoring model (Sharpe-weighted composite with Wilson-bound win-rate), capped fractional Kelly sizing, the MEV-resistant submission path (Flashbots-style private bundles via a Polygon-compatible relay), the threat model (compromised operator, malicious source wallet, oracle manipulation, RPC censorship), the audit results (Trail of Bits Q1 2026, no medium-or-higher findings), and the roadmap (Base & Arbitrum, on-chain strategy registry, social attestations). --- ## Comparison: Poly Syncer vs Polymarket native ([https://mail.polysyncer.com/vs/polymarket-native](https://mail.polysyncer.com/vs/polymarket-native)) Polymarket's native UI is a pure execution venue: place orders, hold positions, settle. It has no leaderboard with risk-adjusted scoring, no automated copying, no portfolio analytics across wallets, no per-trader attribution, and no risk controls beyond manual order entry. Poly Syncer sits on top of Polymarket and adds the discovery layer (rank wallets), the execution layer (mirror trades in <1s on Elite), the risk layer (stop-loss, max drawdown, circuit breakers), and the portfolio layer (attribution, equity curve, tax export). Poly Syncer is non-custodial — funds remain in your Polygon wallet — so the user keeps Polymarket's native settlement guarantees while gaining automation. Pricing: Polymarket native is free to use (you pay only Polymarket's spread); Poly Syncer is $299 (Pro) or $499 (Elite) per month on top. --- ## Comparison: Poly Syncer vs Kalshi ([https://mail.polysyncer.com/vs/kalshi](https://mail.polysyncer.com/vs/kalshi)) Kalshi is a CFTC-regulated US prediction exchange with KYC and a centralised order book in USD. Polymarket (and Poly Syncer) is non-custodial, USDC-settled on Polygon, and globally accessible (ex restricted jurisdictions). Differences that matter for copy-trading: Kalshi has no public on-chain wallet history, so wallet-level alpha is impossible to observe; Polymarket exposes every trade on-chain. Kalshi enforces KYC and US-only access (with limited international expansion); Poly Syncer requires no email or KYC. Settlement: Kalshi USD, Polymarket/Poly Syncer USDC. Latency: Kalshi web UI is fine for manual trading but offers no copy-execution layer. Liquidity: Kalshi deeper on US-political markets, Polymarket deeper on global, crypto, and sports. Poly Syncer does not currently support Kalshi; this page exists to explain the architectural reasons. --- ## Comparison: Poly Syncer vs Manual tracking ([https://mail.polysyncer.com/vs/manual-tracking](https://mail.polysyncer.com/vs/manual-tracking)) Manual tracking means watching wallet addresses in a block explorer or a spreadsheet and placing trades by hand. Cost analysis: a trader monitoring 10 wallets manually misses ~40% of trades simply because the source wallet trades while they're asleep or away. Even when awake, manual replication adds 30-90 seconds of latency, during which the Polymarket book moves. Poly Syncer mirrors deterministically in <1s (Elite) or <3s (Pro), 24/7, with size scaling and risk caps. The cost of the Pro plan ($299/mo) is recovered if it captures even one missed trade per week on a 5-figure book. Manual tracking also has no risk-adjusted scoring — humans chase recent winners (recency bias); Poly Syncer weights Sharpe and drawdown, not just ROI. --- ## Blog ([https://mail.polysyncer.com/blog](https://mail.polysyncer.com/blog)) Long-form research.
