About Cohven and the methodology
Cohven is a small independent tool that rebuilds the portfolios of profitable Polymarket wallets from public blockchain data and shows where several of them agree. This page explains who is behind it, how every number on the site is produced, and what the numbers cannot tell you.
Who builds it
Cohven is built and run by a small independent team of traders and engineers. It is not a fund, does not manage money and does not take positions on behalf of anyone. The public parts of the site, the whale tracker, the event pages and the track record, are free. The application is paid and prepaid. Questions, corrections and data disputes are welcome.
How the numbers are built
1 · Wallet selection
The cohort is a list of public Polygon addresses. Each user picks their own wallets, up to the plan limit. The only requirement is a P&L that can be verified on the chain: no self-reported returns, no screenshots, no leaderboards copied by hand. The public pages use the wallets tracked across all Cohven accounts, with the account owners’ own wallets excluded.
2 · Chain rebuild
For every wallet, Cohven replays its full Polymarket history from Polygon and the public Polymarket APIs: trades, splits, merges, conversions and redemptions. The result is a complete portfolio with the number of shares, the average entry price and the realized P&L of every market, recomputed rather than read from a leaderboard. Histories are compacted into daily fills so that no wallet ever needs its whole activity held in memory.
3 · Consensus and quorum
A market side becomes a cohort position when at least three distinct cohort wallets hold it at once. That number is the quorum, and it is shown on every row. Positions below the quorum are still visible in the wallet views but never presented as the cohort opinion.
4 · Weight, not shares
Every position is expressed as a share of its owner’s equity. A $50,000 position in a $5,000,000 wallet is one percent; the same position in a $100,000 wallet is fifty percent. Comparing wallets by weight is what makes a cohort of very different sizes comparable at all.
5 · Gap
Gap is the difference between your book and the cohort, row by row, in shares and dollars for your account size. It uses the cohort average entry and the worst entry paid, the current book price and your target weight. Gap suggests sizes; it never places a trade.
6 · Snapshots and delay
Public pages are built from snapshots of the rebuilt database and refreshed with the site, with the measurement time printed on each page. Inside the application, cohort moves are shown after they are held, not the second a trade prints. The delay is deliberate: it filters probes and exits and leaves positions.
Data sources
Polygon
On-chain activity of the tracked wallets: trades, splits, merges and redemptions of Polymarket conditional tokens.
Polymarket public APIs
Market metadata, resolutions, order books and price history from the public Data, Gamma and CLOB APIs. Read only.
Nothing private
No user keys, no exchange logins and no private data. Cohven has no access to any funds and executes no trades.
Limitations
- —Historical results of tracked wallets do not guarantee future results. The cohort is chosen by users, and its composition changes.
- —Realized P&L depends on when a wallet sold or redeemed. A position can resolve against the cohort and still show a profit, or the reverse.
- —Public APIs cap how deep a wallet’s history can be read. Very large or very old wallets can be reconstructed only partially, and the application marks those cases.
- —Prices on public pages are snapshots. The book price you get will differ.
- —Cohven shows what wallets hold and what that would mean for your account. The decision, the order and the risk are yours.
