The Infra Layer Between Prediction Markets And Social Media
A Chrome extension that detects prediction market links on X and lets you buy or sell outcome shares — right inside the feed, no tab-switching required.
How it works
Scoop removes every friction point between reading a prediction and acting on it.
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.
One click connects MetaMask. Scoop checks you're on BSC Mainnet and handles all three token approvals automatically in a single flow.
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.
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
Injected directly into X posts. Click without leaving the conversation thread.
Real-time midpoint price from the orderbook rendered as a clean probability bar.
Full CLOB support — buy outcome shares or sell your existing position at the current bid.
Your keys stay in MetaMask. Scoop never touches your private key — all signing happens in-wallet.
Your held shares are read directly from the BSC ERC-1155 contract — no Probable dashboard required.
Toggle paper mode to simulate orders without spending real USDT. Great for testing.
All three required token approvals (USDT, CTF tokens) handled automatically on first use.
Optional companion bot that posts live market updates and probability changes to X automatically.
Technical
Chrome MV3 extension with no backend. All logic runs client-side in the browser.

Roadmap
Scoop is extensible by design. Here's where it goes from here.
Reply to any prediction market post on X with a bet command — no extension needed. Tag the bot and specify your position.
@scoop_bet YES $25 in any replyTweets often reference multiple markets at once. The next version of the popup bundles them all into a single scrollable panel.
Prediction markets get discussed everywhere. Scoop's content-script architecture makes new platforms a matter of adding a detector.
Longer-horizon features once the core is battle-tested.
