MarketLineMarket Line is a news feed app that integrates real-money prediction markets from Kalshi via dFlow on Solana. You can read news about sports, crypto, politics, economics, weather, and entertainment — and trade on the outcomes you believe in.
Each market is a Yes/No question about a future event. You buy "Yes" shares if you think the event will happen, or "No" shares if you think it won't. Shares are priced between 0¢ and 100¢ — the price reflects the market's estimated probability. If you're right, each share pays out $1.00. If you're wrong, it pays $0.00.
Connect your Solana wallet (Phantom, Solflare, Backpack, or use the built-in wallet via email signup). Fund your account with USDC using the "Fund Wallet" button. Then browse markets and click Yes or No to place a trade.
USDC is a stablecoin pegged 1:1 to the US dollar on the Solana blockchain. You can buy USDC directly through our built-in on-ramp (powered by MoonPay and Coinbase) using a credit card, debit card, or bank transfer. Click "Fund Wallet" after connecting.
Each market has specific resolution criteria listed on its detail page. Markets resolve based on official sources (e.g., NFL results, BLS economic data, NOAA weather records). When a market resolves, your shares automatically pay out $1.00 (correct) or $0.00 (incorrect).
Yes! You can sell your shares at any time before the market closes. Click "Sell" on your position from the Dashboard or the market detail page. You'll receive the current market price for your shares.
Points track your engagement on Market Line. You earn points by trading (10 pts per trade), maintaining daily streaks (bonus multiplier), referring friends (100 pts per signup, 200 pts when they make their first trade), and reading news. Points determine your rank on the leaderboard.
The leaderboard ranks users by points earned through trading, reading, referring friends, and daily streaks. Top traders earn badges and recognition on their profiles.
Market Line charges a 0.35% platform fee on trades. This fee is applied automatically when you place an order. There are no deposit or withdrawal fees from Market Line (network fees for Solana transactions are typically less than $0.01).
Your funds are held in your own Solana wallet — Market Line never has custody of your assets. Trades are executed via dFlow, a decentralized order flow protocol on Solana, with markets provided by Kalshi (a CFTC-regulated exchange). Always trade responsibly and only risk what you can afford to lose.
We support Phantom, Solflare, Backpack, and any wallet that implements the Solana wallet standard. On Solana Seeker phones, the native wallet works via Mobile Wallet Adapter (MWA). If you don't have a wallet, you can sign up with email and we'll create an embedded wallet for you.
Share your unique referral link from the Referrals page. When someone signs up using your link, you both earn 100 points. When your referral makes their first trade, you earn an additional 200 points. Milestones at 5, 25, and 100 referrals unlock badges and bonus rewards.
