xStocks support on 0x

Last updated: June 26, 2026

What Are xStocks?

The Big Idea

xStocks are tokenized equities: blockchain-based tokens that give holders price exposure to real-world stocks and ETFs. Issued by Backed Finance (xStocks), each token represents 1:1 exposure to an underlying share held by a regulated custodian.

💡 Think of it as bringing US equities on-chain; so anyone with an internet connection can trade stocks like Apple, NVIDIA, Tesla, or Microsoft without needing a traditional brokerage account.

How They Work

xStocks tokens are ERC-20 tokens deployed across multiple blockchains including Ethereum, Solana, Arbitrum, etc. Examples of available xStocks include:

  • AAPLx — Apple xStock

  • NVDAx — NVIDIA xStock

  • TSLAx — Tesla xStock

  • MSFTx — Microsoft xStock

  • SPCXx — SpaceX xStock (the first tokenized IPO on xStocks)

A key differentiator: xStocks trade 24/7, including weekends (something traditional stock exchanges don't allow). This means users could trade SpaceX stock over a weekend before traditional venues even reopened on Monday.

Regulatory Structure

xStocks are regulated by the FMA (Liechtenstein Financial Market Authority) under the Liechtenstein Blockchain Act, and are issued by Backed Assets (JE) Limited, a Jersey Private Limited Company based in Jersey, Channel Islands. They are classified as Public Equity in RWA (Real World Asset) databases.

Important caveats:

  • xStocks provide price exposure only — not direct ownership of shares

  • They are not available to US persons, or in the UK, Canada, or Australia

  • Capital is at risk, and geographic restrictions apply

xStocks and 0x

0x integrated xStocks support into its API, making them accessible to hundreds of exchanges and millions of users. Key points about the integration:

  • xStocks are blocked by default on the 0x API

  • Integrators must explicitly opt in to enable xStocks trading

  • By opting in, integrators take on full compliance responsibility (e.g., geoblocking non-eligible regions)

  • 0x acts solely as a neutral software provider and makes no representations about the legality or regulatory status of xStocks tokens

xStocks are also tradable on Matcha (0x's consumer DEX aggregator) for non-US users.

Why It Matters

Tokenized real-world assets have graduated from a narrative play to serious volume. Onchain RWAs have more than tripled over the past year to roughly $34B, and tokenized stocks are one of the fastest-growing RWA segments. Traditional institutions see the potential of bringing 24/7 settlement and onchain composability to assets that have traded the same way for decades.

0x is positioned as a strong partner in the RWA space, working with xStocks ahead of competing aggregators. Over 30 teams have already opted in, including Coinbase, Robinhood, Trust Wallet, Kraken Wallet, OpenSea, Rabby and Mayan, with adoption ramping up as more integrators work through their compliance requirements.
