How it works

From tweet to trade
in four steps.

Scoop removes every friction point between reading a prediction and acting on it.

01
🔍

Detect

Scoop scans your X feed in real time. When it spots a Probable Markets link, it injects a Bet button inline — no page reload, no popups.

02
🦊

Connect

One click connects MetaMask. Scoop checks you're on BSC Mainnet and handles all three token approvals automatically in a single flow.

03

Sign

Pick YES or NO, enter your USDT amount. Scoop builds an EIP-712 CLOB order and prompts MetaMask for a gasless signature — no transaction fee for signing.

04

Done

Your order goes live on Probable's off-chain orderbook. When it fills, your outcome tokens appear on-chain and your balance updates in the panel.

Features

Everything you need.
Nothing you don't.

Inline Bet Button

Injected directly into X posts. Click without leaving the conversation thread.

📊

Live Probability

Real-time midpoint price from the orderbook rendered as a clean probability bar.

💹

Buy & Sell

Full CLOB support — buy outcome shares or sell your existing position at the current bid.

🔑

Non-Custodial

Your keys stay in MetaMask. Scoop never touches your private key — all signing happens in-wallet.

🏦

On-Chain Balance

Your held shares are read directly from the BSC ERC-1155 contract — no Probable dashboard required.

📝

Paper Trading

Toggle paper mode to simulate orders without spending real USDT. Great for testing.

🔒

Auto Approvals

All three required token approvals (USDT, CTF tokens) handled automatically on first use.

🤖

Twitter Bot

Optional companion bot that posts live market updates and probability changes to X automatically.

Technical

Built on open standards.
