Open the Add Assets screen in Zelcore and you'll find a token called NVDAB that tracks Nvidia, another called TSLAB that tracks Tesla, sitting next to Bitcoin and Ethereum with no brokerage account attached to any of them. These are bStocks, and the fact that a wallet with no relationship to a stock exchange can hold one is the whole story worth unpacking. This is Part 1 of our bStocks series, and it answers the question a beginner asks first: what is this token actually a claim on, and who is standing behind it?
What a bStock Actually Is
A bStock is a tokenized security — a digital certificate that represents a financial instrument rather than a direct share, and that tracks one underlying US-listed stock or ETF 1:1. Tickers follow a simple pattern: take the underlying symbol and add a "B" suffix. NVDAB tracks Nvidia, TSLAB tracks Tesla, SPCXB tracks SpaceX — the same B-suffix pattern extends across Zelcore's catalog of roughly 65 supported stocks and ETFs. One token is meant to move in lockstep with one share of the real thing.
bStocks first launched on Binance on June 11, 2026, and were extended to BNB Chain on July 2, 2026 with 15 stocks available at launch. Zelcore's own catalog, server-driven and updated independently of the wallet's release schedule, now lists around 65 US stocks and ETFs. The product grew fast, reportedly reaching roughly $500 million in assets under management within seven weeks of that June launch — with about 41.5% of users new to traditional stock investing.
bStocks aren't the only attempt at putting a stock on-chain — other tokenized-equity approaches like Backed and xStocks use different legal structures for a similar goal; bStocks are one design among several. One detail worth flagging early: the number of tokens in your wallet doesn't change when the underlying company pays a dividend or splits its stock. Instead, a mechanism called a share multiplier adjusts how many shares each token represents behind the scenes. We cover exactly how that works, including how the share multiplier handles dividends and splits, in Part 2 of this series.
Who Issues bStocks: BTech Holdings and Its Binance Relationship
bStocks are issued by BTech Holdings Ltd, a special purpose vehicle (SPV) registered in Abu Dhabi Global Market (ADGM) and a Binance group affiliate. An SPV is a standalone legal entity created to hold a specific set of assets or obligations, separate from its parent company's broader business.
It's worth being precise here: BTech Holdings is not Binance itself. It's the dedicated issuing entity that holds the regulatory approval to offer bStocks and that admits them to ADGM's Official List. Binance operates the trading, conversion, and wallet experience on top of that structure. Behind BTech Holdings sits Nest Trading Limited, the ADGM-regulated broker connecting Binance's front end to the custody chain underneath. That layered affiliate structure matters for weighing where the risk in this product sits, which is the focus of the last part of this series.
What an FSRA-Approved ADGM Prospectus Does and Doesn't Guarantee
ADGM is a financial free zone in Abu Dhabi with its own regulator, the Financial Services Regulatory Authority (FSRA). On June 11, 2026, the FSRA approved BTech Holdings' prospectus — the offering document disclosing how a security works and what backs it — admitting bStocks to ADGM's Official List as Certificates over Shares.
That approval is real, but it's worth being clear about what it means. It means the offering document meets ADGM's disclosure and listing standards, and BTech Holdings is regulated by the FSRA for this specific activity. It is a securities-market approval, not a government guarantee of the token's value, and not a deposit-insurance-style backstop. Binance itself is explicit that bStocks are "not stocks or shares" but certificates representing financial instruments — a distinction worth sitting with if you're coming from crypto, where a token in your wallet often is the asset rather than a claim on one.
FSRA regulation covers how bStocks are issued and listed; it doesn't vouch for smart-contract security, Binance's operational risk, or the solvency of custodians further down the chain. The general version of this question — how much a legal wrapper vs on-chain representation actually promises — is one we've covered in more depth elsewhere.
The 1:1 Backing and Custody Chain
Every bStock in circulation is meant to be backed 1:1 by a real US share, purchased and held at a regulated US broker-custodian. Binance verifies this daily on a public Proof of Collateral page, which is meant to let anyone check that the tokens outstanding are matched by shares actually held.
The operational chain behind a single conversion: an order placed through the Binance app routes through Nest Trading Limited, the ADGM-licensed broker, to Alpaca Securities LLC, a US firm handling execution, clearing, custody, dividend distribution, and corporate actions, ultimately settling through the standard US clearing system. BTech Holdings sits at the top as the SPV that legally issues the token. It's described as a special purpose vehicle, but Binance's own materials don't use the term "bankruptcy-remote" for this structure — treat that protection as unconfirmed.
This is the same kind of layered stack — issuer, broker, custodian, clearing system — behind most tokenized real-world assets; we've mapped the custody and counterparty chain behind an RWA generically elsewhere on the site.
Token Format: BEP-20 on BNB Smart Chain
Mechanically, a bStock is a BEP-20 token issued on BNB Smart Chain (BSC) — the same token standard used by USDT-BSC, BUSD, and most BSC-based DeFi assets. If you've ever held a BSC token before, you already know the shape of this one.
bStocks also integrate BEP-677, a standard often described as "Scaled UI Amounts," which lets the balance a wallet displays change through the share multiplier mentioned earlier, without any on-chain mint, burn, or transfer event. That mechanism is what makes dividends and splits invisible at the transaction level, and it's covered in full in Part 2.
Because it's a standard BEP-20 token, any BSC-compatible self-custody wallet — Zelcore included — can hold, send, and receive a bStock exactly like any other BEP-20 asset. Self-custody here means the private keys, and control of the tokens, belong to you rather than an exchange. No Binance account or KYC check is required just to hold one. Binance's own documentation confirms users can withdraw bStocks to their own wallet — Binance Wallet, Trust Wallet, or any BSC address — for full self-custody. Part 3 of this series walks through how to buy and sell bStocks in Zelcore step by step.
Buying through Zelcore's swap does depend on where you connect from: Part 4 explains which regions can buy bStocks in Zelcore and why the option can disappear.
24/7 Tradability and Why That's Different From the Underlying Stock
Here's the part that genuinely departs from how stocks normally work: bStocks trade around the clock, both on-chain and on Binance's spot market, while the underlying stock listed on the NYSE or Nasdaq only trades during US market hours. Converting between shares and bStocks settles in under a second according to BNB Chain's own materials, with zero conversion fees charged by the protocol itself.
That around-the-clock window is also where a real-world quirk shows up: because the token can trade when the underlying market is closed, its on-chain price can drift away from the last traded NYSE or Nasdaq price until the market reopens and the two reconnect. A beginner watching a bStock move overnight, with no news and no US market open, should expect that gap. It's the single biggest practical difference between owning a bStock and owning the stock through a broker.
Risks to understand before you participate
- Approval is not a guarantee. FSRA regulation of the prospectus means BTech Holdings met ADGM's disclosure and listing bar — not that the token's value, the smart contract, or Binance's operations are guaranteed by any authority.
- You're relying on a certificate, not a share. Binance calls bStocks certificates over financial instruments rather than direct shares — a legal distinction worth understanding.
- The custody chain has several links. BTech Holdings, Nest Trading, and Alpaca Securities each play a role in getting a real share behind your token, and a failure anywhere in that chain is a risk you're exposed to even in your own wallet.
- The "bankruptcy-remote" question is open. BTech Holdings is described as an SPV, but that specific legal protection hasn't been confirmed in Binance's own materials.
- Price can diverge from the real market. 24/7 trading means the on-chain price can separate from the last NYSE/Nasdaq print while US markets are closed.
- Access isn't universal. Who can actually hold bStocks depends on where you are, and Zelcore enforces that at the wallet level — covered in Part 4.
None of this is legal or tax advice; treat it as a starting map, not a final answer, and check the primary sources linked throughout before making decisions.
Key takeaways
- A bStock is a certificate token, backed 1:1 by a real US share, issued by BTech Holdings Ltd — a Binance affiliate — under an FSRA-approved ADGM prospectus, not Binance itself.
- FSRA approval covers disclosure and listing standards for the offering; it is not a guarantee of value or a substitute for understanding the custody chain behind the token.
- Backing runs through Nest Trading Limited to Alpaca Securities LLC, which holds the actual shares and handles execution, clearing, and corporate actions; Binance publishes a daily Proof of Collateral page.
- As a standard BEP-20 token on BNB Smart Chain, a bStock can be held, sent, and received in any BSC-compatible self-custody wallet, including Zelcore, with no Binance account required.
- bStocks trade 24/7, unlike the underlying stock, which means their on-chain price can diverge from the exchange price while US markets are closed — a normal quirk, not a malfunction.
