What 0x does

• Swap API routes trades across Robinhood Chain DEXes for integrating apps
• RFQ quotes from market makers for stock tokens, mainly against USDG
• Cross-Chain API moves assets to and from Robinhood Chain
• Used by wallets such as Robinhood Wallet (partner since 2023)

0x is a paid API for integrators; apps can add their own fees on top of routed swaps.

0x provides swap aggregation as an API rather than an app, routing orders across the chain’s DEXes for the wallets and front-ends that integrate it, with a gasless path for meta-transactions. Robinhood Chain appears in its published supported-chain list and its settler contracts carry code here. DefiLlama ranks the 0x aggregator first on this chain by volume — $72.4M over 24 hours and $4.83B all time on 18 September 2026. There is no 0x token on this chain.
