Reality is the RWA issuance platform behind rToken, strategically backed by Bitget. It connects rToken to the underlying U.S. securities through regulated brokerage, custody, settlement, and blockchain infrastructure. Reality also engages U.S.-registered accounting firm The Network Firm to publish daily Proof of Reserves reports, verifying the 1:1 correspondence between issued rTokens and the underlying holdings.

Reality's official website: https://realityfinance.xyz

rABVX is deployed on the Arbitrum network. Users can view detailed issuance information for rABVX on the rABVX token details page on Reality's official website (https://realityfinance.xyz/en/market/detail/ABVX). Users can also use the rABVX token contract address to look up information such as the issuer (Reality) identifier for rABVX and its Proof of Reserves records on an Arbitrum blockchain explorer.

The ABVX tokenized stock issued by Reality is rABVX, an RWA crypto token that tracks real Abivax S.A. stock on a 1:1 basis through blockchain technology and is supported for trading by Bitget.

Key features include:

1. Price tracking and economic benefits: Its price movements track Abivax S.A. stock (ABVX) in the U.S. market in real time, and holders can receive dividends automatically distributed in USDT.

2. Crypto asset flexibility: It can be purchased directly using stablecoins such as USDT and supports fractional trading starting from as little as 1 USDT.

3. 24/7 trading and multiple uses: It supports 24/7 trading and can also be used directly as margin for futures trading or as collateral on crypto exchanges such as Bitget.

Bitget users can buy rABVX on Bitget's spot stock market through the rABVX/USDT trading pair.

Yes. rABVX is a real-world asset (RWA) token issued by the licensed issuer Reality and supported for trading by Bitget.

Here's why:

1. Backed by a real underlying asset: rABVX is not a purely synthetic crypto asset. It is issued by the licensed RWA protocol Reality, with each rABVX backed 1:1 by real Abivax S.A. shares (ABVX) held in custody with a compliant U.S. broker.

2. Tokenized on-chain: It tokenizes real-world stock assets from traditional finance (TradFi), allowing them to be transferred, traded, and settled in token form on the blockchain or through the crypto exchange Bitget.

3. Exposure to real economic benefits: Holders can benefit from changes in the underlying stock price and receive dividends generated by the underlying shares, which are automatically distributed in USDT. This reflects a key characteristic of RWA assets: linking on-chain tokens to real-world cash flows and economic rights.

rABVX is a Abivax S.A. tokenized stock issued by the licensed RWA protocol Reality. It is backed 1:1 by real Abivax S.A. stock (ABVX) and can be traded on the crypto exchange Bitget through the rABVX/USDT trading pair. Its pricing and operating mechanisms are as follows:

Price formation and tracking

Real-time price tracking: The price of rABVX tracks Abivax S.A. stock (ABVX) listed on the U.S. stock market on a 1:1 basis.

Direct access to native liquidity (during U.S. market hours): During regular, pre-market, and post-market trading sessions in the U.S. stock market, rABVX spot orders are routed directly through the system to the Nasdaq or NYSE order book for execution, resulting in zero spread and eliminating depegging risk.

On-exchange pricing (when U.S. markets are closed or on weekends): When the U.S. stock market is closed, rABVX switches to 24/7 on-exchange trading. Its price is generally based on the most recent U.S. stock market closing price and fluctuates dynamically based on buy and sell orders matched on the crypto exchange.

Underlying asset and economic rights

1:1 backing by real assets: Each rABVX token issued is backed 1:1 by real shares of Abivax S.A. held in custody with a compliant U.S. broker such as Alpaca. The reserves are also subject to daily Proof of Reserves (PoR) verification using Merkle tree data.

Minting and burning: When a user or institution subscribes to rABVX on the platform, Reality purchases the corresponding amount of Abivax S.A. stock in the U.S. market and mints new tokens. Upon redemption, the tokens are burned and the corresponding stock reserves are released.

Automatic dividend distribution and stock split handling:

Dividend payouts: When Abivax S.A. stock pays a dividend in USD, a 30% U.S. withholding tax is automatically deducted. The remaining net dividend is converted to USDT and distributed to users' crypto accounts in proportion to their holdings.

Stock splits and reverse splits: In the event of a stock split, reverse split, or other corporate action, the system automatically adjusts the amount of rABVX in users' accounts proportionally, with no manual action required.

Crypto utility and unified trading account use: rABVX has the flexibility of a crypto asset. In addition to 24/7 trading, it can be used directly as margin for futures trading or as collateral for crypto borrowing in the unified trading account (UTA).

ABVX is the underlying Abivax S.A. stock, while rABVX is the Abivax S.A. tokenized stock issued by Reality and supported for trading by Bitget, backed 1:1 by ABVX stock. rABVX brings ABVX stock on-chain.

Here's how the two are related and how they differ:

1:1 backing: rABVX is issued by Reality, with each rABVX backed by one real share of ABVX held in reserve. As a result, rABVX's market performance and price movements track those of the underlying ABVX stock.

Economic benefits (dividends and stock splits): Holding rABVX provides economic benefits corresponding to those of the underlying stock. For example, when ABVX pays a dividend, rABVX holders receive a proportional dividend distribution converted to USDT in their accounts. Adjustments for stock splits and reverse splits are also reflected accordingly.

Legal status and trading access:

ABVX: Holders directly own shares in a publicly listed company through a traditional securities broker, with their equity interests subject to regulation by the SEC (U.S. Securities and Exchange Commission).

rABVX: An RWA crypto token issued on the blockchain. It does not confer direct shareholder status or voting rights in Abivax S.A., but provides corresponding economic exposure to the underlying asset.

Trading flexibility:

ABVX is generally traded in whole or fractional shares through a traditional broker during available U.S. stock market trading sessions, using fiat currency such as USD.

rABVX can be traded 24/7 on the crypto exchange Bitget using stablecoins such as USDT. It supports flexible fractional trading and can also be used as collateral or margin for crypto derivatives trading.

Although rABVX tracks the price movements and dividend returns of ABVX stock on a 1:1 basis, the two differ significantly in their underlying structure and use cases:

1. Asset structure and legal status

ABVX: Represents equity in a publicly listed company. Holders are registered shareholders of the company and have voting rights at shareholder meetings. The stock is regulated by financial authorities and organizations such as the SEC (U.S. Securities and Exchange Commission) and FINRA (Financial Industry Regulatory Authority), while eligible brokerage accounts may also be protected by SIPC (Securities Investor Protection Corporation).

rABVX: An RWA crypto token issued on-chain by Reality and supported for trading by Bitget. Holders receive economic exposure corresponding to that of the underlying shares but do not directly own shares in Abivax S.A. or have shareholder voting rights.

2. Trading hours and settlement

ABVX: Trading is limited to U.S. stock market trading sessions, including regular trading hours from 9:30 AM to 4:00 PM ET as well as available pre-market and after-hours sessions. Trades are settled in U.S. dollars, and fund movements are subject to the clearing and settlement cycles of the traditional financial system.

rABVX: Tradable 24/7 using stablecoins such as USDT, with funds credited within seconds and no need to wait for currency conversion or traditional settlement.

3. Accessibility and fractional trading

ABVX: Typically requires opening an account with a traditional broker and completing identity and address verification.

rABVX: Offers a simpler account-opening and identity verification process, with fractional purchases starting from as little as 1 USDT, lowering the barrier to entry.

4. Crypto utility and capital efficiency

ABVX: A traditional financial asset that cannot directly participate in the blockchain ecosystem or crypto trading.

rABVX: Has the flexibility of a crypto token. In addition to spot trading, it can be transferred directly, used as margin in a unified trading account on a crypto exchange such as Bitget, or used as collateral to borrow crypto assets, enabling highly efficient capital use.

Holding rABVX does not make you a direct shareholder and does not grant voting rights. rABVX is a tokenized asset issued by Reality and supported for trading by Bitget, rather than direct equity in the company.

No direct shareholder status: rABVX is essentially an RWA (real-world asset) token issued on-chain by Reality and backed by real shares held in custody. The underlying Abivax S.A. shares are held in custody with a compliant broker under the issuer's name, so you are not directly registered as a shareholder of Abivax S.A..

No voting rights at shareholder meetings: Because you are not a registered shareholder, you cannot participate in Abivax S.A.'s shareholder meetings or vote on major corporate matters, such as board elections or major acquisition proposals.

Economic benefits only: Although you do not have voting rights, you can still receive the economic benefits associated with the underlying stock, including gains from changes in its market price and USDT dividend distributions based on your holdings when Abivax S.A. pays a dividend.

No. They are two completely separate products and should not be confused with each other.

rABVX/USDT on the spot market: The spot trading pair for rABVX, the RWA token based on ABVX stock. rABVX is issued by Reality and supported for trading by Bitget. It is a tokenized stock asset backed 1:1 by real Abivax S.A. shares (ABVX), and holders are entitled to the corresponding economic benefits of the underlying stock, including dividends and adjustments for stock splits.

ABVXUSDT on the futures market: A futures derivative linked to ABVX stock. The ABVXUSDT perpetual futures contract is a separate derivative offered by Bitget for trading the price movements of Abivax S.A. stock. It does not represent ownership of the underlying stock or confer dividend rights, and it is not linked to Reality's Proof of Reserves mechanism.

Simply put, rABVX is a tokenized representation of the stock, while ABVXUSDT perpetual futures contract is a derivative linked to the stock. The two differ in their risk structures, economic rights, and funding rate mechanisms, so users should clearly distinguish between them when choosing what to trade.

When Abivax S.A. undergoes a stock split or reverse stock split, the quantity and price of rABVX, issued by Reality and supported for trading by Bitget, are automatically adjusted accordingly, while the total value of each user's rABVX holdings remains unchanged.

The adjustment mechanism and process are as follows:

Holdings and unit price are adjusted proportionally:

Stock split example (e.g., 10-for-1): If you hold 1 rABVX, once the stock split takes effect, your rABVX balance automatically increases to 10, while the unit price of rABVX is adjusted to one-tenth of its previous price. Your total position value remains unchanged.

Reverse stock split example (e.g., 1-for-10): If you hold 10 rABVX, once the reverse stock split takes effect, your rABVX balance automatically decreases to 1, while the unit price of rABVX is adjusted to 10 times its previous price. Your total position value remains unchanged.

Fully automatic, with no action required: Once the underlying U.S. shares held in custody by Reality complete the stock split or reverse stock split at the clearing level, the platform automatically updates users' on-chain and account holdings in the background. No manual withdrawal, conversion, or other action is required.

Temporary trading suspension and order cancellation: During the clearing window when a stock split or reverse stock split takes effect, the platform typically suspends trading of rABVX and automatically cancels unfilled orders. Trading resumes automatically once account reconciliation and token quantity adjustments are complete.

Automatic adjustment of futures margin and collateral: If rABVX is used as margin for futures trading or pledged as collateral for borrowing, the system automatically adjusts the collateral quantity and index mark price based on the stock split or reverse stock split ratio, helping ensure that your leverage and margin health are not affected by the change in quantity.

rABVX is issued by Reality and supported for trading by Bitget, with 24/7 trading available. You can continue to buy and sell rABVX when U.S. markets are closed or on weekends, with different pricing mechanisms applying during different trading periods.

U.S. market closures and weekend trading: rABVX is tradable 24/7

During U.S. market hours (including pre-market, regular, and after-hours sessions): rABVX orders are routed directly to the Nasdaq or NYSE order book, with prices synchronized in real time with the underlying U.S. stock market.

When U.S. markets are closed or on weekends: The system switches to on-exchange crypto market trading. Users can continue to place orders and trade using USDT on the exchange at any time.

rABVX does not depeg

When U.S. markets are open (no depegging): Orders are routed directly to the U.S. stock market for execution, and execution prices track current U.S. stock prices directly, so depegging does not occur.

When U.S. markets are closed or on weekends (market-driven pricing rather than depegging):

While the U.S. stock market is closed and no new stock prices are being quoted, the price of rABVX on the crypto exchange is determined by buy and sell orders matched on the exchange.

If major news breaks over the weekend, such as policy changes or significant industry developments, rABVX may rise or fall in advance as market sentiment is reflected in its price. This represents early price discovery in the crypto market outside U.S. trading hours. When the U.S. stock market reopens on Monday, the price can quickly realign with the underlying stock market through the live order book.

Weekend trading risk notice

Lower liquidity than usual: With no native U.S. stock market liquidity during market closures, the order book may be thinner, and larger trades may face slightly wider bid-ask spreads.

Liquidation protection when used as futures margin: If rABVX is used as margin for futures trading, the platform typically uses Friday's U.S. stock market closing price as a fixed index mark price over the weekend for risk calculations, helping prevent small on-exchange price fluctuations from triggering liquidation.

The two methods have very different fee structures. A general comparison is provided below:

1. Buying ABVX through a traditional broker, such as Longbridge, Moomoo, Futu Securities, or IBKR

Trading commissions and platform fees: Many U.S. stock brokers now offer zero-commission trading, charging only a small platform fee of around $0.99–$1 per trade. Some brokers that do not charge platform fees have trading costs close to zero.

Cross-border funding and FX conversion costs (the main cost): For users outside the U.S. who fund their accounts in local currency to buy U.S. stocks, bank wire transfer fees and FX spreads of around 0.5%–1.5% can represent the main hidden costs.

Regulatory fees: Stock sales may incur small SEC regulatory fees and FINRA trading activity fees, typically amounting to only a few cents per trade and having minimal impact on overall costs.

2. Buying rABVX, issued by Reality, on the crypto exchange Bitget (trading pair: rABVX/USDT)

Transaction fees: Standard crypto exchange spot transaction fees apply, with base rates typically around 0.05%–0.1%. Fees may be reduced further by holding a platform token such as BGB or reaching a higher VIP level.

No fiat FX conversion costs: You can trade directly using USDT held in your account, avoiding the fiat FX conversion and cross-border wire transfer costs typically associated with traditional finance.

No SEC fees: As the transaction involves an on-chain token rather than a directly cleared U.S. stock trade, the related regulatory fees do not apply.

Recommendations by scenario:

If you hold crypto such as USDT, buying on a crypto exchange may be more cost-effective. Converting USDT into USD cash and then buying ABVX through a traditional broker may incur P2P conversion costs, bank deposit and withdrawal fees, and FX fees, with combined costs typically around 1%–2% or more. By comparison, buying rABVX directly on a crypto exchange may incur only a transaction fee of around 0.05%–0.1%.

If you hold non-USD cash, buying on a crypto exchange may also be more cost-effective. Converting non-USD cash into USD and then buying ABVX through a traditional broker may involve FX spreads, wire transfer fees, and broker platform fees or commissions, with combined costs typically around 0.5%–2% or more. Buying rABVX directly on a crypto exchange avoids fiat FX conversion and cross-border wire transfers, leaving only a spot transaction fee of around 0.05%–0.1%. This may offer greater cost and capital efficiency.

If you hold USD cash, buying through a traditional U.S. broker may be more cost-effective. Funding a brokerage account directly in USD can provide access to zero-commission or very low-cost trading. Converting USD into USDT first to buy rABVX may instead introduce an additional funding cost.

rABVXは、原資産であるABVX株への1:1のエクスポージャー、24時間365日の取引、分割取引、配当金の支払い、プラットフォームの総合取引アカウントおよびUSDT-M先物でのマージンとしての利用資格といった機能を提供します。

つまり、米国の証券口座がなくても、USDTなどの暗号資産を使用してrABVXを購入でき、ABVX株へのエクスポージャーを得ながら、ABVXの配当に相当する経済的利益も受け取れます。

rABVXの取引は、BTCやその他の暗号資産の取引とほぼ同じです。このプラットフォームでは、米株取引サービスを通じて直接ABVX株を購入することも可能です。

rABVXの仕組み：

1. USDT建てで直接取引：資金を米ドルに変換したり、海外送金を行ったりする必要はありません。ウォレットまたはアカウントにあるUSDTを使用して、ABVX株式トークン（通常はrABVXと表示されます）を直接売買できます。

2. 分割取引：株式トークンはブロックチェーン上で細分化が可能なため、ユーザーは1株全体を購入するのではなく、わずか数USDT分のABVXを購入することができます。

3. 1:1の経済的エクスポージャーと配当：このカテゴリーの資産は、Realityなどのコンプライアンスに準拠したRWA発行体によって裏付けられており、原資産に対して1:1の経済的エクスポージャーを提供します。原資産である米国上場企業が現金配当を支払うと、Bitgetは自動的にその配当をUSDTに変換し、ユーザーの口座に分配します。

4. 深いエコシステム統合：Bitgetのユニバーサル取引所（UEX）フレームワークの下で、ABVX株式トークンは現物市場で取引できるほか、総合取引アカウント、マージン取引、グリッド取引ボット、デリバティブ全体でもサポートされる可能性があります。

rABVXの立ち上げと運営には、複数の当事者間の協力が関与しています：

rABVX発行者：Reality Protocol—Bitget傘下のライセンス取得済みRWAプロトコル。Reality Protocolは、RWA株式トークンのオンチェーン発行と、対応する裏付け株式資産の保管を担当し、各トークンが実際の保有資産と1:1で対応することを保証します。

株式保管ブローカー：Alpaca Securities—米国FINRAに登録された規制対象のブローカーであり、SIPCの対象となっています。Alpaca Securitiesは、すべてのRWAトークンの裏付けとなる株式資産の保管を担当し、各トークンが実際の保有資産によって裏付けられていることを保証します。

資産検証：The Network Firm—独立した第三者機関。The Network Firmは、Realityがカストディで保有する裏付け株式の保有状況を独立して検証し、第三者として保証を提供しています。

取引および流動性プラットフォーム：Bitget—当取引所は主要な現物およびデリバティブ取引の場として機能し、rABVXをUSDTで直接取引するために必要な流動性を提供します。

rABVXはArbitrumチェーン上で実行されます。ユーザーは、ネットワークをサポートするウォレット、またはBitget総合取引アカウントを通じて、オンチェーンおよびオフチェーンで資産を操作できます。

rABVXは、実際のABVX株によって1:1で裏付けられるように設計されています。

Reality Protocolが公開したメカニズムによると、ユーザーがBitgetでrABVXを購入すると、発行者はAlpaca Securitiesなどの認可を受けたブローカーを通じて、米国株式市場で対応する量のABVX株を購入・保有します。

rABVXは、原資産の経済的利益を1:1の比率で反映します。これは、rABVXの価格変動、配当（自動的にステーブルコインに換算されて分配される現金配当など）、および株式分割などのコーポレートアクションが、原資産であるABVX株と同期していることを意味します。

rABVXは、原資産とそのコーポレートアクションを1:1で追跡します：

現金配当の直接支払い：株式からの現金配当は自動的にUSDTに換算され、お客様のアカウントに直接入金されます。支払時期と金額は明確に表示されます。

株式配当を直接付与：株式配当は、株式トークンとして1:1でリアルタイムにお客様のアカウントへ付与され、取得単価と総資産額も即時に更新されます。

リアルタイムの株式分割および株式併合：株式分割および株式併合はオンチェーンでリアルタイムに反映されるため、保有資産は米国株式市場と完全に同期した状態が保たれ、デペグ（価格乖離）リスクを最小限に抑えることができます。

rABVXのリアルタイム価格は$0です。正確で最新の価格データについては、このページの上部をご確認ください。最終価格、24時間の価格変動、過去の価格チャート、PER、配当利回り、配当額、その他の株式データなど、主要な指標が24時間リアルタイムで更新されています。また、下にスクロールして今日のrABVX価格に関する詳細な分析をご覧いただくか、「取引」ボタンをクリックして取引ページに移動し、詳細なライブオーダーブックや深度チャートを確認することもできます。

Bitgetでの先物取引のマージンとして、対象となる株式トークン（rToken）を使用できます。

Bitgetは、クロスアセット総合取引アカウント（UTA）およびマルチアセットマージンモードを開始しました。これにより、ユーザーは主要な米国株やETF（Apple、Tesla、Nvidia、Microsoft、Amazon、SPY、QQQなど、数百の資産）に連動する対象のトークン化された資産を、統合マージンプールに含めることができます。

要点：

マルチアセットマージン：総合取引アカウントまたはマルチアセットマージンモードを有効にすると、これらの株式トークンは、原資産の価格へのエクスポージャーを提供するだけでなく、USDT-M先物などのデリバティブや先物取引のマージンとしても使用できます。

資本効率の向上：トークン化資産を売却したり、ステーブルコインに変換したりする必要はありません。それらを直接マージンとして使用することで、ポートフォリオ全体の資本効率を向上させることができます。

リスク警告：トークン化された資産をマージンとして使用すると、アカウント全体のレバレッジが高まります。株式トークンの価格が下落した場合、追証（マージンコール）や強制決済が発生する可能性があるため、ポジションのリスクを慎重に管理してください。
