Introduction

ASTSB is the tokenized version of AST SpaceMobile stock, issued on BNB Smart Chain as part of Binance's bStocks program. It allows users to gain economic exposure to AST SpaceMobile — the satellite broadband company — through a blockchain-native token that can be traded and deployed in DeFi around the clock.

Unlike buying shares on a traditional exchange, ASTSB lives on-chain, meaning it behaves like a crypto token while tracking the value of the underlying equity.

History & Background

Binance launched bStocks in June 2026, introducing tokenized U.S. equities as BEP-20 tokens on BNB Chain. The program grew rapidly, with over 700 assets becoming available within weeks of launch. ASTSB is part of this expanding catalogue of tokenized securities, issued by BTech Holdings Limited, a Binance-affiliated company regulated in the Abu Dhabi Global Market (ADGM).

How AST SpaceMobile Tokenized (bStocks) Works

Each ASTSB token represents one unit of economic exposure to AST SpaceMobile stock, with the underlying shares held by a regulated custodian. The token price tracks the real stock via oracle price feeds, keeping valuations aligned with live market data.

Users can acquire ASTSB by converting existing AST SpaceMobile stock holdings or by purchasing directly using USDT, USDC, or BNB. The conversion is 1:1 with no fees, and users can redeem tokens back to shares at any time.

Tokenomics

ASSTB does not have an independent monetary policy. Its supply is entirely determined by demand — new tokens are minted when users tokenize shares, and tokens are burned upon redemption. This design ensures the token supply always reflects actual, custodied equity holdings. There are no inflationary emissions, staking rewards, or governance allocations.

Ecosystem & Use Cases

As a BEP-20 token, ASTSB is composable with the broader BNB Chain DeFi ecosystem. Holders can:

• Trade ASTSB 24/7 on supported platforms without waiting for traditional market hours
• Provide liquidity or lend via protocols such as Venus, Lista DAO, and PancakeSwap
• Earn yield on top of any dividends passed through from the underlying stock
• Self-custody by withdrawing tokens to a personal wallet like Trust Wallet

Team, Governance & Community

ASSTB is issued and managed by BTech Holdings Limited, operating under Binance's broader product umbrella. The program is centrally administered — there is no on-chain governance or DAO. Custody of underlying shares is handled by regulated financial counterparties, with daily Proof of Collateral published to verify that tokens remain fully backed.

Advantages

• 24/7 trading — no restriction to stock exchange opening hours
• Near-instant settlement — on-chain transactions settle far faster than traditional T+1 clearing
• DeFi composability — use equity exposure as collateral or liquidity in DeFi protocols
• Zero conversion fees — no cost to move between stock and token
• Self-custody option — full control of assets without relying on a broker

Risks & Challenges

• Not direct ownership — ASTSB is legally a certificate, not a direct shareholding; holders have no voting rights in AST SpaceMobile
• Custodian risk — the value of ASTSB depends on the regulated custodian faithfully holding the underlying shares
• Regulatory uncertainty — tokenized securities operate in an evolving regulatory environment globally
• Platform dependency — the product relies on Binance infrastructure; any disruption to services could affect access
• Oracle risk — price accuracy depends on the reliability of oracle feeds used to track the underlying stock

Long-Term Vision

bStocks, and ASTSB within it, represent a broader ambition to merge traditional finance with decentralized infrastructure. The vision is a world where equity ownership is borderless, programmable, and accessible around the clock. As tokenized real-world assets continue gaining traction, products like ASTSB could become a standard bridge between stock markets and the on-chain economy.
