polyfees

Free · 30-day fee receipt · public address only

How much did you pay Polymarket in fees over the last 30 days?

Not a per-trade calculator. Paste your profile address and get your real 30-day fee bill, read from the blockchain to the cent, with your result, what you'd have without fees, and whether you hold losers and sell winners.

Public data only. Nothing to connect, nothing to sign.

Where do I find my address?
  1. In Polymarket tap your avatar (top right) → Settings.
  2. Open Profile. The Address field is it: 0x and 42 characters. Tap the copy icon.
  3. Or open your profile page and copy the address under your name; the URL reads polymarket.com/@name or …/profile/0x…. Pasting the whole URL works too.

Not the address under Deposit → Transfer crypto. That is a funding address, a different one, and it shows no trades.

No address at hand? Open a sample receipt for a public wallet.

What's on the receipt

Line 1

Result, last 30 days

Resolved positions, after fees. The same number Polymarket shows as realized PnL.

Line 2

Fees you paid the exchange

To the cent, from the fee receipts of your own transactions on Polygon. Not an estimate.

Line 3

What you'd have without fees

And the upper bound of what a resting order would have saved. A resting order does not always fill, so we say "up to".

Line 4

Hold or sell

Positions you held to the end against the ones you sold along the way, and how many of each ended in profit.

How we count

0

Keys asked

You paste a public address. We read what anyone can read on the blockchain. There is nothing to approve and nothing to sign.

30

Days

One month of trades, market results and fee receipts. Long enough to mean something, short enough to count in a minute or two.

1¢

Precision

Fees come from transaction receipts, not from a formula. If the chain says $135.53, the receipt says $135.53.

Only the latest 10,000 trades are visible through the public API. When that cap applies, the receipt says "at least". Full method · how Polymarket fees work.
