What is Traderline?

Traderline’s Polymarket product combines an execution interface with wallet research. Sonar adds holder tables, live trades and wallet profiles so an unusual order can be investigated without leaving the terminal. The current product page lists the Polymarket and Betfair products as free; their platform availability differs.

Who it is for

  • Desktop traders who prefer ladder execution
  • Users studying the wallets behind large fills

Pricing and total cost

The current official site advertises both venue products as free without a subscription. Underlying exchange charges and the account’s trading costs are separate.

Getting started

Before you start: The documented Polymarket setup uses a signer private key imported into the local application; this is more access than a read-only wallet lookup.

  1. Download the correct desktop version from Traderline.
  2. Choose the Polymarket connection guide.
  3. Check the supported account/wallet creation flow.
  4. Follow the local signer setup instructions.
  5. Open a market and inspect the ladder.
  6. Use Sonar before configuring a trade.

Our take on Traderline

Ladder trading and integrated holder research provide a focused desktop workflow. Importing a signer key grants substantially more access than wallet lookup, and free software does not remove venue charges.
