Brand and media

​
One-liner

Siren is a prediction market trading terminal on Solana.

​
Short description

Siren aggregates live markets from Kalshi and Polymarket into one terminal. Browse markets, trade YES/NO positions, track your portfolio, and manage risk in one place.

​
Voice

  • Plain, direct language.
  • Lead with what the product does, not what it aspires to do.
  • Sound like a builder, not a pitch deck.
  • No hedging. No filler. No buzzwords.
Examples:
  • “Trade prediction markets from Kalshi and Polymarket in one terminal.”
  • “See all your positions and PnL in one place.”
  • “When a trade fails, Siren tells you why.”

​
Colors

Siren uses a minimal palette:
  • White: #FFFFFF
  • Black: #000000
  • Signal green: #00FF85
Black and white as the base. Green sparingly for signal, confirmation, and key focus states.

​
Typography

Headers use Clash Display Variable. Body copy uses a clean supporting face. The logo mark stands on its own without extra label text when space is tight.

​
Naming

  • Siren
  • onsiren.xyz
  • @sirenmarketsxyz
The brand name has not changed. The product focus has sharpened.

​
How to pitch Siren

Short pitch:
Siren is a prediction market trading terminal on Solana. It aggregates Kalshi and Polymarket into one feed, handles adaptive trade execution, and gives you a unified portfolio with risk intelligence.
Longer pitch:
  • Prediction markets are split across platforms with no unified experience.
  • Traders check multiple sites, track positions manually, and get no help when trades fail.
  • Siren puts it all in one terminal with smart execution, clear outcomes, and real risk alerts.
  • The product includes a natural language agent, a trading competition leaderboard, and onchain swaps.

​
What Siren is not

  • Not a replacement for Kalshi or Polymarket. Siren routes to them.
  • Not a leverage venue.
  • Not a token launchpad.
