What is Rainbow?

The getting-started guide covers creating and backing up a wallet, portable keys generated on the device, copying a public address and reviewing a send. Retain the backup privately: ordinary password reset cannot recover a wallet without it. The send flow separates recipient, asset, amount and final confirmation, and the receiving network and asset must match.

The screenshots are older official wallet and transfer examples with no supplied capture dates; they do not show the newer prediction-order flow or current market data. The introductory article uses older Ethereum-specific wording, so check present network support and Predictions in the current app. Desktop extensions are offered, but identical prediction features across platforms were not established.

Who it is for

For mobile users evaluating a wallet with Polymarket access and researchers distinguishing wallet management from prediction-account requirements.

Features and coverage

Mobile Polymarket presentation
The official product page presents Polymarket inside the phone app. Separate Hyperliquid perpetuals do not establish leverage for predictions.
Device keys and recovery backup
The guide describes device-generated keys and portability to compatible wallets. Recovery depends on retaining the backup privately.
Recipient, asset and amount review
Inspect the recipient, supported network, asset, amount and confirmation screen before a transfer; historical examples do not establish current support.
Charts and Rainbow Black upgrade
The site describes prices and charts beside trading and a Black rewards upgrade. A numeric Black price and complete prediction-fee table were not established.

Workflows with Rainbow

Evaluate the phone prediction path

Download from the official site, inspect Predictions and compare the intended market with Polymarket rules. Check local eligibility, collateral and all quoted costs before considering an order.

Prepare a current-app transfer

Identify the network and public receiving address in the current app and compare with the sender. Keep the recovery phrase private and inspect final confirmation.

Pricing and total cost

Official downloads and help are public. Rainbow Black is advertised, but its price and complete prediction trading fees were not established. Network, deposit and transaction costs depend on the funding route and current quote.

Getting started

Before you start: Older support examples are Ethereum-specific and are not current market data. Use the current app to check networks and features; desktop prediction parity is not established.

Use the current official iPhone or Android download link.
Create or import a wallet through the documented flow and retain its recovery backup privately.
Inspect current Predictions, rules, eligibility, funding network and quote before considering funded action.

Prediction-specific fees, regional eligibility, custody details and executed orders remain unverified. No wallet was created or connected in the recorded review.

Our take on Rainbow

Explicit Polymarket positioning and clear wallet-backup guidance make Rainbow a useful mobile candidate. Older onboarding images, incomplete prediction costs and the untested order path limit this documentation assessment.
