Roosevelt starts as a Rosen-centric tool: every Ergo asset, plus every asset Rosen Bridge wraps onto Ergo, traced back to its real origin. Free stays free on every chain we support. Paid tiers unlock as chain coverage grows. Plus (Beta) will open for early-bird access as soon as the full feature set is live on Ergo, with most tooling already built and little remaining before its soft launch. Pro (up to 5 chains) opens once Cardano, Bitcoin, Ethereum and Binance reach the same bar, and Premium (every chain) once we're caught up with everywhere Rosen Bridge itself goes.
Rosen Bridge Adapter
Live
Full cross-chain bridge-history search across every version of Rosen's guard contracts, tracing a Rosen-wrapped asset back to its real origin chain.
MEW Bridge Adapter
Live
Recognizes NFTs bridged from Cardano to Ergo via MEW Bridge, tracing their real origin the same way as a Rosen-wrapped asset.
Token Verification
Live
Origin, bridge source, verification status, and circulation for any Ergo asset or bridged asset — free, public, no login required.
Bulk Verification
Live
Verify many assets in one request instead of one at a time — a free taste for anyone, a deeper monthly quota on Plus.
Flag — Community Reporting
Live
Free, public token and wallet reporting, reviewed before publishing, surfacing as a "Reported" badge right on an asset's passport card.
Free Tier — Ergo
Live
Everything above, packaged for Ergo: free-tier verification for Ergo assets and every Rosen Bridge- or MEW Bridge-wrapped asset, plus full cross-chain origin tracing.
Plus Tier — Ergo
Beta
Single-chain subscription: cross-chain duplicate/plagiarism detection, bulk verification, and a portfolio dashboard are live, with a token burner for unwanted or flagged tokens still left to build. Plus will open for early-bird access as soon as the full feature set is live on Ergo, and will stay in beta for bug fixes, community feedback, and ErgoPay/Terminus integration before moving from beta to a full public launch.
Cardano
Planned
Native verification app for Cardano assets and wrapped Rosen-Centric bridged coins, tokens and NFTs on the Cardano blockchain, with the same Plus-tier feature set as Ergo.
Bitcoin — Coin & Runes
Planned
Native verification for Bitcoin itself and for Bitcoin Runes token/NFT wraps, launching together under one bitcoin.roosevelt.app subdomain so Bitcoin support isn't partial at launch — even though Rosen Bridge (and Bitcoin's own ecosystem) treats plain Bitcoin and Runes as genuinely separate integrations under the hood. Same Plus-tier feature set as Ergo. Wrapped Bitcoin Ordinals may follow as a further addition.
Ethereum
Planned
Native verification app for Ethereum assets and wrapped Rosen-Centric bridged coins, tokens and NFTs on the Ethereum blockchain, with the same Plus-tier feature set as Ergo.
Binance
Planned
Native verification app for Binance assets and wrapped Rosen-Centric bridged coins, tokens and NFTs on the Binance blockchain, with the same Plus-tier feature set as Ergo.
Pro Tier — Up To 5 Chains
Planned
Opens once Ergo, Cardano, Bitcoin, Ethereum and Binance all carry the full Plus-tier feature set — subscribers pick up to 5 of them, with verification quota pooled across the whole selection. Subscription payment — fiat or DeFi, via a planned Banxa integration — is targeted to launch alongside Pro.
Doge & Firo
Planned
Rounding out the remaining chains Rosen Bridge itself supports today. Firo has now launched on Rosen Bridge and is supported there, clearing the dependency this stage was waiting on.
Premium Tier — Every Rosen-Supported Chain
Planned
The full business/deep-user tier: uncapped verification, API access, white-label badging, across every chain Rosen Bridge supports.
Next Bridge — Likely Solana Or Base
Planned
Roosevelt's first ecosystem entirely outside Rosen Bridge, scoped well ahead of time rather than after Premium ships. Solana and Base are both large, fast-growing NFT/token markets in their own right — and both are on Rosen Bridge's own further roadmap, so by the time Rosen wraps assets onto them, Roosevelt's native coin/token/NFT adapter work is already done and only the Rosen-wrapped side needs adding.
Order beyond Ergo is guided by real usage and tier readiness, not a fixed date.
