Lot-accurate PnL

FIFO, LIFO or Average cost basis with settlement treated as a first-class disposal — redemptions and expiries close lots correctly, not just sales.

On-chain reconciliation

Every settled position is cross-checked against real REDEEM payouts, and resolutions are inferred when the exchange's own status lags.

Region-aware tax views

Profiles for regions Polymarket actually allows — India, UAE, Hong Kong, Japan and more — never a guessed number where the law is unsettled.

Questions traders actually ask

No. PolyLedger only reads public on-chain trade history and Polymarket's own trade/activity API for the address you give it. There is nothing to sign and nothing to approve — it can't move funds because it never asks for the permission to.

FIFO, LIFO and Average Cost are all supported and you can switch between them from the top bar at any time — the whole ledger recomputes instantly. Most jurisdictions expect a specific method (Average Cost is a safe default); check with a local professional if you're unsure which one your filing requires.

Two different reasons, and PolyLedger tells you which one applies. If Polymarket itself blocks access from your region — the US, UK, Singapore and about a dozen others, per Polymarket's own restrictions — PolyLedger refuses to generate a tax view for it rather than pretend a rate applies. If your region is simply allowed but not yet modeled, you get a neutral, tax-rate-free view of gains and losses instead of a guess.

Yes. Polymarket's documented pagination caps out at roughly 3,500 trades, but PolyLedger walks the full history using a time cursor instead — verified pulling 9,000+ trades from a single high-frequency wallet the standard path capped at 3,500. Your realized gains and cost basis are computed over every trade, not a recent slice.

Every position the engine marks as settled is cross-checked against the wallet's real on-chain REDEEM payouts, to the cent. If Polymarket's own market-status flag lags behind actual resolution, PolyLedger infers the outcome from the on-chain redemption itself and tells you it did so — it never silently guesses.

No. Prediction-market contracts are taxed differently — and often unsettled in law — from one jurisdiction to the next. PolyLedger computes the underlying economic numbers precisely; a licensed professional in your jurisdiction should confirm how those numbers get filed.
