Introduction

ISRGx is a blockchain-based tracker certificate that mirrors the price of Intuitive Surgical Inc. (Nasdaq: ISRG), a global leader in robotic-assisted surgery. It belongs to the xStocks family of tokenized equities created by Backed Finance, one of the most established real-world asset (RWA) issuers in the crypto space.

For eligible investors, ISRGx offers a crypto-native way to gain economic exposure to Intuitive Surgical's stock performance — without needing a traditional brokerage account.

History & Background

Backed Finance AG was founded in 2021 in Switzerland, inspired by the growing adoption of stablecoins and aimed at bringing regulated, traditional assets onto the blockchain. In May 2025, Backed launched the xStocks product line, initially covering 60+ U.S. stocks and ETFs. ISRGx was included as part of this broader rollout, giving on-chain access to Intuitive Surgical alongside blue-chip names like Apple, Tesla, and Nvidia.

In late 2025, Kraken's parent company Payward agreed to acquire Backed Finance AG, further cementing the platform's institutional backing.

How Intuitive Surgical tokenized stock (xStock) Works

The mechanism behind ISRGx is straightforward. When a token is issued, Backed Finance purchases actual ISRG shares through traditional brokers and deposits them with regulated custodians — including Alpaca Securities LLC (FINRA-regulated) and Swiss banks InCore Bank and Maerki Baumann. For every real share held in custody, exactly one ISRGx token is minted.

This 1:1 collateralization means the token's price closely tracks the underlying ISRG stock. Tokens are freely transferable on-chain and can be held in self-custody wallets, settling at blockchain speed (effectively T+0) rather than the traditional T+1 cycle.

Tokenomics

ISRGx is a fully collateralized tracker certificate, not an algorithmic or synthetic instrument. New tokens are minted only when the corresponding real shares are purchased and placed in custody. Conversely, tokens are burned when holders redeem and the underlying shares are sold. This dynamic supply model means the number of tokens in circulation at any given time directly reflects the amount of ISRG shares held in custody on behalf of token holders.

Ecosystem & Use Cases

ISRGx can be used in several ways:

• Price exposure — track Intuitive Surgical's stock performance via a crypto wallet
• 24/7 trading — trade on platforms like Kraken and Bybit outside traditional market hours
• DeFi composability — as a permissionless on-chain token, ISRGx can potentially be used within DeFi protocols for lending, collateral, or liquidity purposes
• Fractional access — investors can hold fractional positions without needing a full share

Team, Governance & Community

Backed Finance AG is a Swiss-regulated fintech whose team combines expertise in traditional finance, blockchain engineering, and regulatory compliance. The xStocks product operates under a legal structure involving Backed Assets (JE) Limited — a Jersey special-purpose vehicle registered with the Jersey Financial Services Commission. There is no governance token or DAO structure; Backed operates as a regulated issuer with centralized oversight over issuance and custody.

Advantages

• 1:1 real-share backing — fully collateralized, not synthetic
• Regulated custody — underlying shares held by FINRA-regulated and Swiss bank custodians
• Self-custody — tokens are freely transferable and can be held in your own wallet
• Multi-chain availability — accessible on Solana, Ethereum, Arbitrum, BNB Smart Chain, and more
• 24/7 trading — no traditional market-hours restrictions
• T+0 settlement — on-chain settlement is near-instant

Risks & Challenges

• Counterparty risk — holders rely on Backed Finance and custodians to maintain the 1:1 backing
• No shareholder rights — ISRGx holders do not receive voting rights in Intuitive Surgical
• Restricted eligibility — U.S. persons are prohibited from purchasing or holding xStocks products
• Regulatory uncertainty — the tokenized securities space continues to evolve across jurisdictions
• Liquidity risk — on-chain liquidity may be limited compared to the underlying stock
• Issuer concentration — the product depends on Backed Finance's ongoing operations and compliance

Long-Term Vision

ISRGx represents a broader shift toward bringing traditional capital markets onto public blockchains. Backed Finance envisions a future where any eligible investor globally can access blue-chip equities through a crypto wallet, composable with DeFi infrastructure. As MiCA regulations mature and institutional adoption of RWA tokens grows, products like ISRGx are positioned to bridge the gap between traditional finance and decentralized markets — making regulated equity exposure as accessible as holding a stablecoin.
