Spot misinformation as you read: select any sentence, check it on Verisphere, and see how much is staked for and against it. Spot misinformation and disinformation as you read — on any site. Select a sentence that makes a claim — in a news article, a Reddit thread, a Quora answer, a forwarded post, anywhere — right‑click, and choose Check on Verisphere. A side panel shows whether that claim is already on Verisphere and how it stands: a Verity Score, which is how much people have staked that the claim holds up versus how much that it doesn’t. It is a credibility signal that is harder to fake than likes, shares or votes, because backing a claim costs the backer something. It is not a verdict, not a vote, and not a prediction about an event. Nothing happens on a page until you ask. Use it to notice when something you are reading is contested, or unsupported, before you believe it or pass it on. A claim nobody is willing to back deserves a second look. On English Wikipedia the extension also underlines the sentences that already have a claim on Verisphere; hover to see the score, click to open the panel. Verisphere is a truth‑staking protocol on Avalanche C‑Chain: people back or challenge factual claims with VSP tokens, and the stake behind each side is the score you see. From the panel you can back or challenge a claim, link evidence between claims, create a claim from a sentence nobody has put on Verisphere yet, and share a claim with its standing. Your wallet (MetaMask, Rabby, Core…) stays in control: the extension only asks it to sign; it never holds keys or funds. If your Verisphere wallet is a passkey, Open in the app takes you to the same claim in Verisphere. Private beta.
