Backd

Quick answers

What does it cost?

A filled call costs 1% of stake and an early cash-out costs 1% of proceeds, plus any venue or bridge costs.[1][2][3][4][5][6]

Does it trade for me?

Current orders need your wallet signature; planned one-tap session trading is awaiting venue enablement.[1][2][3][4][5][6]

Where do my funds sit?

The provider says money remains in your own venue wallet and Backd does not keep your keys.[1][2][3][4][5][6]

What do I need to start?

An adult eligible user, email login, a supported browser wallet and accepted funds.[1][2][3][4][5][6]

Where is it available?

A private-beta web product subject to venue location restrictions; not every documented future feature is live.[1][2][3][4][5][6]

Overview

Trading mode

Current orders are signed by the user. One-tap delegated orders and money challenges remain conditional on Polymarket enabling session signers for Backd.[1][2][3][4][5][6]

Funding and prerequisites

An email address, age 18 or above, Phantom or MetaMask and funds in an accepted deposit token or existing Polymarket balance. New positions also require being in a venue-supported location.[1][2][3][4][5][6]

What it offers

• Backed calls

  A call can correspond to a real outcome position bought through the venue book rather than just a stated opinion.[1][2][3][4][5][6]

• Social record

  Calls appear on profiles and feeds with entry prices, current prices and an eventual settled record.[1][2][3][4][5][6]

• Shareable slips

  Generate a link or slip for a call; sharing is separate from whether a new order fills.[1][2][3][4][5][6]

• Combo positions

  The current-status page describes live money combos with a venue quote and a wallet signature for the complete slip.[1][2][3][4][5][6]

• Position management

  View fills, pending transfers and settled positions, with early sale and a separate claim action.[1][2][3][4][5][6]

Getting started

What you need first

An email address, age 18 or above, Phantom or MetaMask and funds in an accepted deposit token or existing Polymarket balance. New positions also require being in a venue-supported location.[1][2][3][4][5][6]

Safety and terms

Custody and keys

The provider says users bring Phantom or MetaMask, retain their keys and use their own Polymarket wallet. Current browser-signed orders require the user signature. A planned trading-only session key is described as unable to withdraw or transfer, but it is not yet enabled.[1][2][3][4][5][6]
