Tokenized equities are one of the fastest-growing categories in onchain finance. 0x launching support for xStocks enables hundreds of products already building on Swap API to move value freely between native tokens and RWAs, even when the markets are closed.

What are xStocks?

xStocks are tokenized versions of real stocks and ETFs. They are issued by Backed, a Swiss-regulated company. Each xStock token represents 1:1 exposure to the underlying share or fund, held by a licensed custodian under Swiss regulatory frameworks.

xStocks are just one form of tokenized equities, a relatively new and exciting offering in the category of tokenized real-world assets (RWAs). As a major driver of institutional adoption, 0x is expanding RWA support to give integrators access to the broadest selection of these tokens.

Because xStocks are standard ERC-20 tokens, they can be traded onchain like any other token, even outside traditional market hours. xStocks can be bought or sold around the clock, including over weekends and holidays, though price updates may lag while the underlying market is closed.

How 0x powers xStocks trading

xStocks liquidity is sourced through 0x RFQ. Trades made through 0x interface directly with market makers, rather than through third-party aggregators. That means quotes for tokenized equities come from the same execution layer that already powers swaps.

For integrators who opt in, xStocks are available through the same Swap API integration already in production, and are sourced and settled through the same infrastructure that already serves 521+ integrators.

Built for compliance: Opt-in to enable

Equities are regulated assets, so 0x will not automatically enable xStocks in your app. xStocks are blocked by default on the 0x API and integrators must explicitly opt in to enable xStocks trading.

By opting in, the integrator takes on compliance responsibility for offering these assets, including geoblocking and any jurisdictional requirements that apply to their users. 0x acts solely as a neutral software provider and makes no representations about the legality or regulatory status of any xStocks token.

This is the first asset type on 0x to require explicit opt-in rather than default support. The model keeps compliance decisions where they belong, with the integrator offering the product, while giving teams a clean and easy path to enable tokenized equities when they're ready.

Why RWAs matter now

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.
