Quick Start

Head to celsa.app. Email, Google, Twitter, or connect a wallet you already use. A trading wallet gets provisioned in the background — you don't install anything.

Two paths:

Card. Tap "Buy with card" in the wallet modal. Visa, Mastercard, Apple Pay, Google Pay via MoonPay. USDC lands on Polygon and auto-converts into your trading balance. 0.5% card fee on the way in.

Crypto. Send USDC or USDC.e on Polygon to the address we show you. We wrap it into pUSD (Polymarket's V2 trading collateral, 1:1 with USDC) before your first trade. Crypto deposits are free.

Your first trades are sponsored. After that, we keep a small POL buffer on your wallet by auto-swapping a tiny slice of your trading balance whenever gas runs low. You don't buy POL, bridge POL, or think about POL.

The first time you hit Buy, we deploy your on-chain trading wallet, mint your Polymarket API credentials, and approve the collateral token. About 30 seconds, no signatures required from you — the wallet handles it. Every subsequent trade skips this step entirely.

Open a market, tap an outcome, type an amount (or hit a preset chip), confirm. The order signs locally and goes straight to Polymarket's order book. Want fast turnover? The crypto panel runs five-minute strike markets on the major tickers.

Every fill credits cashback to your wallet. Scout tier starts at 5%; Syndicate caps at 30%. Refer someone with your link and you also earn on their trades, plus their referrals, plus one more level down. Three levels deep, no cap, paid in USDC.e.
