General

Matchr is a prediction market aggregation platform that unifies liquidity across multiple platforms like Polymarket and Kalshi. We help traders find the best prices, discover matched markets, and execute trades seamlessly across platforms.
No, Matchr is not a prediction market itself. We aggregate and route orders to existing prediction markets. Think of us like a flight search engine—we don’t operate the flights, but we help you find and book the best options.
Currently, we support:
  • Polymarket — The largest crypto prediction market (global, non-US)
  • Kalshi — CFTC-regulated prediction market (US only)
More platforms coming soon.
Yes, browsing markets and comparing prices is completely free. We only charge a small fee when you execute trades through our platform.
We earn a small percentage on trades executed through our platform via builder fees. We also plan to offer premium features for power users and institutional clients.

​
Trading

  1. Connect your wallet (social login or existing wallet)
  2. Set up your Safe trading wallet (one-time)
  3. Fund your account with USDC
  4. Start trading!
See our Quickstart Guide for detailed instructions.
A Safe (formerly Gnosis Safe) is a smart contract wallet on Polygon that enables gasless trading. Instead of signing every transaction, your Safe can execute trades on your behalf, making the experience seamless.
You can fund your Safe wallet by:
  • Bridging USDC from Ethereum, Arbitrum, Base, or Solana
  • Buying USDC directly with a credit/debit card
  • Transferring USDC (Polygon) from any exchange
Always send funds to your Safe wallet address, not your connected wallet.
  • Platform Fee: Small percentage on trades (varies by market)
  • Gas Fees: Zero! We cover all gas fees
  • Deposit/Withdrawal: Network fees may apply when bridging
Fees are always shown before you confirm a trade.
Yes! We support both market orders and limit orders. Limit orders let you set your desired price and wait for it to fill.
When a market resolves:
  1. The winning outcome is determined
  2. Winning shares are worth $1.00 each
  3. Losing shares are worth $0.00
  4. You can redeem winnings in your Portfolio
Winnings are automatically sent to your Safe wallet in USDC.

​
Matched Markets

Matched markets are equivalent markets on different platforms asking essentially the same question. For example, “Will Trump win in 2024?” might exist on both Polymarket and Kalshi.We use AI to automatically find these matches.
Price differences occur because:
  • Different user bases with different information
  • Varying liquidity levels
  • Regulatory differences (Kalshi is US-only)
  • Different fee structures
These differences create arbitrage opportunities.
Our AI matching uses semantic embeddings with pgvector. Each match has a confidence score:
  • High (90%+): Almost certainly the same market
  • Medium (75-90%): Very likely the same, minor differences possible
  • Low (60-75%): Similar but may have different resolution criteria
We continuously improve our matching algorithm.
Currently, you can identify arbitrage opportunities through Matchr, but executing cross-platform trades requires accounts on both platforms.Coming Soon: Automated arbitrage execution through our vault system.

​
Wallets & Security

Your funds are stored in a Safe smart contract wallet that only you control. We never have custody of your funds. The Safe infrastructure is battle-tested and secures billions of dollars across DeFi.
If you used social login:
  • You can recover access through your linked social account (Twitter, Discord, email)
  • Privy securely manages your embedded wallet
If you connected an external wallet:
  • Use your wallet’s standard recovery process
  • Your Safe is linked to your wallet address
Yes! You can connect multiple wallets to your account. Each wallet gets its own Safe and API credentials. This is useful for: - Separating trading strategies - Managing different portfolios - Using different funding sources
Matchr primarily operates on Polygon for Polymarket integration. We’re expanding to support Solana for future vault infrastructure.

​
Platform Access

No, Polymarket is not available to US residents due to regulatory restrictions. However, US users can trade on Kalshi, which is CFTC-regulated.Matchr shows you which markets are available based on your location.
Platform availability varies:
  • Polymarket: Global (except US and sanctioned countries)
  • Kalshi: US only
We recommend checking each platform’s terms of service for specific restrictions.
It depends on the platform:
  • Polymarket: No KYC required
  • Kalshi: Full KYC required (US regulation)
Matchr itself does not require KYC for basic features.

​

Vaults are managed investment pools where professional traders execute strategies on behalf of depositors. You deposit USDC, the vault trades prediction markets, and you share in the profits.

  • Management Fee: 2% annually on AUM
