Introduction
Celsa is a Polymarket trading terminal. Live prices, fast fills, the tools a real trader actually uses. Not just a chart with a Buy button.
TL;DR
What Celsa is
Polymarket is the biggest prediction market on the internet. Crypto five-minute strikes, sports moneylines, political races, weather forecasts — thousands of live markets at any given moment. Celsa gives you a real terminal to trade them: live order book, multi-outcome charts, whale flow, cashback on every fill.
You don't install anything. Sign in with email, Google, Twitter, or connect a wallet you already use. We provision an on-chain trading wallet behind the scenes — no seed phrase to copy, no browser extension to manage. Polygon gas is handled automatically.

Under the hood
Celsa connects to Polymarket's CLOB (central limit order book). Your order gets signed locally — the private key never leaves your device — then submitted to the book. A match settles on Polygon in pUSD, Polymarket's trading collateral. We never custody your funds; they sit in a smart contract wallet only you can move.
You can withdraw any time, to any supported chain. We don't need permission, and we couldn't freeze your balance even if we wanted to.
