A wallet feature with venue/location restrictions and separate account security controls.[1][2][3][4][5]

Overview

Trading mode

The prediction guide describes user/device-signed orders. General AI-agent capabilities are not sufficient evidence of unattended prediction copying in this source-bounded profile.[1][2][3][4][5]

Funding and prerequisites

An eligible adult Summo account with accepted funds and working device/co-signer access. Polygon is named for prediction trading; broader network support is not a universal deposit specification.[1][2][3][4][5]

What it offers

• Outcome orders

  The prediction guide describes Yes/No shares without leverage, with the stake paid defining position exposure.[1][2][3][4][5]

• Fill-or-kill behavior

  The documented order must fill completely at its quoted price or be cancelled.[1][2][3][4][5]

• Rules before entry

  Each market’s own resolution rules are shown before a position is taken, with venue-controlled settlement.[1][2][3][4][5]

• Co-signed transactions

  A device signature and the provider’s policy-checked co-signature normally authorize account actions.[1][2][3][4][5]

• Fee payment options

  Network fees can be paid in the native coin, through a supported-token paymaster or using a separate gas-credit balance.[1][2][3][4][5]

Pricing and fees

Trading fee

A prediction-market service fee is itemized before confirmation. No numeric rate was found in the reviewed prediction and fee pages.[1][2][3][4][5]

Other fees

Network gas is separate. The paymaster adds a service charge when it pays gas in a supported token; a native-coin payment has no added Summo charge according to the fee guide. Gas credits are a distinct provider-held credit balance.[1][2][3][4][5]

Minimum amounts

Minimum prediction position usd:

1

No subscription plans, according to the provider. The reviewed fee guide explicitly states there is no monthly or account fee.

Getting started

What you need first

An eligible adult Summo account with accepted funds and working device/co-signer access. Polygon is named for prediction trading; broader network support is not a universal deposit specification.[1][2][3][4][5]

Safety and terms

Custody and keys

The account model describes a two-of-three wallet: the user’s device and backup keys derive from one recovery phrase, while Summo holds a co-signer. Summo says it cannot move funds alone. Routine service access still depends on its co-signature and policy checks.[1][2][3][4][5]
