A token swap looks simple. Behind the button, liquidity has to come from somewhere. 0x provides APIs and smart-contract infrastructure for token swaps, liquidity access, and trading workflows. Its product suite is built for applications that need execution and market access across supported crypto networks. Liquidity is the pool of assets available to trade. Routing is how a swap finds its path through those pools. Those are different jobs. Explore 0x on Hood L two. Find the project links, its full description, and the sources behind the listing.

Frequently asked questions
- What does 0x do on Robinhood Chain?
- Two things from launch: it supplies RFQ market-maker liquidity for Stock Tokens (USDG base pair) via the Swap API, and it is the cross-chain swap provider in Robinhood Wallet for reaching the chain from other networks.
- Why RFQ instead of an AMM for Stock Tokens?
- RFQ asks market makers for executable quotes. The price depends on their inventory and the requested amount; compare it with available pool quotes and costs.
- Can I reach Robinhood Chain from another chain via 0x?
- The Cross-Chain API in Robinhood Wallet supports Stock Token trades and USDG transfers involving Ethereum, Arbitrum, Base and Solana in one transaction.
