Introduction

Bitmine xStock (BMNRx) is a tokenized equity instrument that brings exposure to Bitmine Immersion Technologies, Inc. onto the blockchain. It is part of the xStocks product suite created by Backed Finance, a company specializing in compliant, on-chain representations of publicly traded stocks and ETFs.

For crypto-native users outside the United States, BMNRx offers a way to gain exposure to the BMNR stock without needing a traditional brokerage account, long settlement windows, or restricted trading hours.

History & Background

Backed Finance launched the xStocks product line on June 30, 2025, bringing over 60 tokenized U.S. equities on-chain across Solana and EVM-compatible networks. Bitmine Immersion Technologies — the company underlying BMNRx — is a publicly traded tech firm focused on holding and managing Ethereum as a primary treasury reserve asset and offering digital ecosystem advisory services.

In December 2025, Kraken announced its acquisition of Backed Finance, integrating xStock minting and settlement natively into the exchange's own infrastructure.

How Bitmine xStock Works

Every BMNRx token is fully collateralized 1:1 by a real share of BMNR stock, held in a segregated custody account by a regulated custodian. The issuing entity is a bankruptcy-remote Special Purpose Vehicle (SPV), meaning collateral is legally isolated from Backed Finance's own balance sheet.

Corporate actions such as stock splits and dividends are handled automatically through an on-chain rebasing mechanism. Token balances adjust to always reflect a true 1:1 exposure to the underlying equity — no manual action needed from holders.

Tokenomics

BMNRx tokens are minted on demand when users purchase exposure through supported venues. The token supply is not capped — new tokens are issued as demand grows, always matched by an equivalent real share held in custody. The economic design ensures the token price closely tracks the underlying BMNR stock price at all times.

There are no governance or staking mechanics tied to BMNRx. The token's value proposition is pure price-tracking and DeFi composability.

Ecosystem & Use Cases

BMNRx is DeFi-composable — meaning it behaves like any other fungible token in the ecosystem. Users can:

• Hold BMNRx for passive exposure to the BMNR stock price
• Provide liquidity in decentralized exchange pools
• Use it as collateral in lending protocols
• Trade it 24/7, unlike traditional stock markets with fixed hours

The broader xStocks ecosystem is integrated with protocols such as Raydium, Jupiter, and Kamino on Solana, and is accessible via wallets like MetaMask and Phantom.

Team, Governance & Community

BMNRx is issued and managed by Backed Finance, co-founded by Adam Levi and others with backgrounds in decentralized governance projects. Backed secured $9.5 million in Series A funding in 2024, led by Gnosis. Following Kraken's acquisition announcement in December 2025, Backed Finance operates with deeper institutional backing and exchange-level infrastructure support.

There is no token-based governance for BMNRx. All decisions about the product structure and compliance are managed centrally by Backed Finance.

Advantages

• 1:1 real asset backing — every token is matched by a real share in regulated custody
• DeFi composability — usable as collateral, in liquidity pools, and across DeFi protocols
• 24/7 trading — no market-hours restrictions like traditional stock exchanges
• Multi-chain availability — live on Ethereum, Solana, BNB Smart Chain, TON, and more

Risks & Challenges

• US-user restrictions — xStocks are not available to US persons, limiting the addressable audience
• Liquidity concentration — trading activity across xStocks tends to concentrate in a small number of popular tokens, which can mean thinner markets for BMNRx
• Counterparty risk — holders depend on the custodian and SPV structure functioning correctly
• Regulatory evolution — the regulatory landscape for tokenized securities continues to shift globally
• Spread and fee costs — market-maker spreads and platform fees can add friction to trading

Long-Term Vision

BMNRx sits at the intersection of real-world asset tokenization and decentralized finance — a fast-growing sector aimed at moving traditional capital markets onto open blockchain infrastructure. Backed Finance's xStocks platform envisions a world where any publicly traded asset can be held in a wallet, transferred in seconds, and integrated into complex financial products without intermediaries.

As institutional adoption of tokenized securities grows, BMNRx and its xStock peers are positioned to serve as foundational building blocks for a new generation of on-chain financial products accessible to users around the world.
