PolyViper

PolyViper enhances polymarket.com with a true trade ledger for any portfolio or profile page you view. WHAT IT DOES ■ True P&L, not averages — reconstructs every position with FIFO lot matching: each sell is paired with the exact buys it closes, so realized P&L reflects what actually happened, fill by fill. ■ Every fee, traced — taker fees are computed per fill and folded into net realized P&L. The official UI shows gross numbers; PolyViper shows what you actually kept. ■ Full event grouping — trades are grouped by event and market, with per-market drill-down to the individual lot matches (L3 detail). ■ Unrealized P&L — open positions are marked against current prices. ■ Uncovered tracing — sells that can't be matched to a buy (splits, merges, conversions, redemptions) are traced through Polymarket's ledger primitives instead of being silently dropped. ■ Inspect any wallet — works on your own /portfolio and on any public profile page. ■ CSV export — download the full ledger, current view, or a tax-style disposal report. ■ Full market titles — removes the "…" truncation on portfolio and profile pages. ■ Native feel — the panel takes over the content area in place (no popup), follows Polymarket's light/dark theme, and follows the site language (English and Chinese built in). HOW IT WORKS / PERMISSIONS All data comes from Polymarket's official public APIs. Everything is computed and stored locally in your browser — PolyViper has no servers, no analytics, no tracking, and never sees your private keys or credentials. It cannot place trades. Host access is limited to polymarket.com and its official API domains; see the privacy policy for details. Note: PolyViper's FIFO methodology intentionally differs from Polymarket's average-cost display, and its realized P&L is net of taker fees (the official figure is gross). A ⓘ note in the panel explains the methodology. PolyViper is an independent open tool and is not affiliated with or endorsed by Polymarket.
