Roosevelt is a cross-chain asset provenance verification tool. Paste a token, NFT, or coin's ID and it tells you where the asset was actually minted — and, if it's a bridged asset, traces its history back to that real origin. Proof of Origin.
It starts as a Rosen-centric tool: every Ergo-native asset, plus every asset Rosen Bridge wraps onto Ergo from another chain, verified and traced back to source. From there, it's built to grow into a complete network verification app — bringing that same verification directly to every chain Rosen Bridge supports, not just to their wrapped copies on Ergo (see Roadmap).
What It Checks
- Origin — Mint transaction, height, creator, and token standard.
- Bridge Origin— For bridged assets, the real source chain, whether it's a coin or a token, and a plain-language summary of how it got here.
- Verification Status — Verified, Flagged, or Unverified. An objective, algorithmic read, not a subjective score.
- Circulation — Whether an asset is still circulating, burned, or redeemed back across the bridge.
- Custody Model — Whether a bridge moves assets through a decentralized guard network (Rosen Bridge) or a centralized single-operator bridge (MEW Bridge), and what that means for how much trust it requires.
What Makes It Different
- Full Bridge-History Search— Checks every version of Rosen's Bridge contracts a wrap could have used, not just the current one, so older wraps don't wrongly show as unverified.
- Two Bridges, Already Covered — Roosevelt is Rosen-centric at its core, but also recognizes NFTs bridged from Cardano to Ergo via MEW Bridge, tracing their real origin the same way as any Rosen-wrapped asset.
- A Real Scam Pattern, Already Caught— Flags a token minted directly on a chain that copies a genuine bridged asset's exact name to look legitimate.
- Free And Public — Every core safety check is free, no login and no paywall. Gating whether a token is safe defeats the point of the tool.
- Built To Embed — A badge widget and JSON API let marketplaces and other sites show the same verification, not just visitors to roosevelt.app.
Flag — Community Reporting
Anyone can report a token or wallet they believe is a scam, duplicate, or otherwise misrepresenting itself — free, public, no login required. A public submission sits in a review queue first: Roosevelt, or an authorized community reviewer, confirms it before anything goes live. Once approved, it shows as a "Reported" badge right on the asset's passport card, alongside Verified and Circulation status, so seeing a warning never sits behind a paywall.
Trusted ecosystem teams and bridge operators — starting with Rosen Bridge — will be authorized to publish a scam or spam status change on their own tokens and wallets directly, the moment they catch it on their own bridge, with no Roosevelt review queue or delay in the way. Once authorized, a team gets its own Review tab in the app: a dedicated queue for managing their ecosystem's token and wallet submissions and status updates. The goal is for the community to find out the instant the people closest to the problem do.
Free, With Plus In Beta
The free tier already covers full verification for anyone, no account required. Plus — a single-chain subscription, in beta now — adds cross-chain duplicate/plagiarism detection, bulk verification, and a portfolio dashboard, all live today. The dashboard currently gives you a list summary of everything your connected wallet holds, alongside a live ERG market widget (price, 24h change, market cap, and a price chart), a Recent Activity feed of newly-published community reports, and a Top Holdings breakdown of your highest-value assets. An upgraded dashboard interface — a customizable layout, plus further additions like watcher stats and bridge activity — is in progress, targeted for completion during this Plus beta phase, before we move from beta to a full public launch. A token burner for unwanted or flagged tokens is still to come.
Plus connects — and will pay — through your own wallet: Nautilus is already integrated as Plus's login, and will double as its payment method too, so subscribing happens directly from your wallet with no third party involved. ErgoPay/Terminus support (for mobile and QR-based wallets) is in progress as well, and will be completed before we move from beta to live. Pro and Premium extend the same features across more chains as coverage grows — see Pricing for what's planned.
