Adds a "Market" button to posts on X that opens market.fun to make a prediction market about that post. market.fun for X adds a Market button to the action bar of every post on x.com and twitter.com, next to reply, repost and like. Click it on any post and market.fun opens in a new tab with a prediction market drafted from that post: the question, the outcomes and the deadline are filled in for you. Sign in on market.fun: with the hosted wallet it is created in one step; with an external wallet you confirm a pre-filled form. The extension sends nothing on its own. It does not read the text of posts, makes no network requests, sets no cookies and has no analytics. It only looks at each post's link to know which post a button belongs to. When you click Market, it opens the market.fun create page with that one post's link in the page address, so the market.fun site receives the link of the post you clicked, and nothing else. Markets are created on the market.fun app, which runs on the Monad testnet, and creating one needs a sign-in there. You can point the button at a different market.fun address, for example a local test server, from the extension's options page.
