0x Now Supports Ondo Stocks

Tokenized equities are starting to show up in onchain liquidity the same way any other asset does: traded on DEXs and AMMs once they're listed. 0x now surfaces that liquidity for Ondo Stocks through 0x Swap API and Cross-Chain API, giving any integrator a single API to quote and route trades in tokenized US stocks, without a direct integration into each individual venue.

How the integration works

0x Swap API aggregates Ondo Stocks liquidity from the DEXs and AMMs already connected to Swap API on Ethereum and BSC, and routes each trade to the best price across them. This is the same aggregation model Swap API uses for any other asset, with no separate infrastructure to learn and no new integration pattern for your team.

Coverage tracks whichever Ondo Stocks tickers are actually listed on those connected venues at a given time, rather than a fixed set. As more tickers reach onchain liquidity, they become tradable through the same integration without any changes on your end.

Two ways to plug in

Swap API and Cross-Chain API cover different parts of the same problem, and both work exactly as they do for any other asset.

If your users are already on Ethereum or BSC, Swap API quotes and executes the trade directly against aggregated liquidity, with no changes to how you call the API today.

If they're not, Cross-Chain API allows a user’s assets to move to a supported network first. Solana is supported on the destination side through bridge providers, so users starting there can still reach Ondo Stocks liquidity and move back out, without a separate application in the flow.

Why this matters beyond the integration itself

Every new asset class a product supports touches more than the API layer: it's a decision about user activation, liquidity access, and compliance posture all at once. Aggregating Ondo Stocks the same way Swap API aggregates everything else means your team doesn't need a new pattern to support them: the same quoting, routing, and settlement flow you already use just picks up a new asset class.

Ondo is one of the largest issuers of tokenized US-listed stocks, and as more of that liquidity comes onchain through standard DEXs and AMMs, it becomes reachable through the same aggregation infrastructure 0x already runs.

"The promise of tokenized stocks starts with access. By aggregating Ondo Stocks liquidity through the same API hundreds thousands of teams already use, 0x turns onchain access to US equities from a one-off integration into a built-in default. That's exactly the kind of distribution this asset class needs to scale to billions of users."
