0x

0x's Robinhood Chain integration is one of the more concrete day-one partnerships, because it is doing two distinct jobs that the chain genuinely needs. The first is liquidity for the product itself: 0x's Swap API exposes RFQ (request-for-quote) liquidity for Stock Tokens, connecting apps to professional market makers who quote executable prices, with USDG as the primary base pair. RFQ, rather than pure AMM routing, is the right structure for tokenised equities — the assets have real off-chain reference prices and thin early on-chain depth, so quoted market-maker pricing tends to beat a shallow pool. The second job is on-ramping: as the cross-chain swap provider inside Robinhood Wallet, 0x lets a user on Ethereum, Arbitrum, Base or Solana buy or sell a Stock Token, or bridge USDG, in a single transaction without juggling separate bridges. That is the difference between a chain that feels reachable and one that feels walled off. The position to take is that 0x is quietly load-bearing for the trading experience: it is both where a meaningful share of Stock Token liquidity is sourced and how retail actually reaches the chain from wherever their funds already sit. The integration is well-evidenced — a dated PR names the RFQ and Cross-Chain components explicitly — and it builds on 0x's Cross-Chain API reaching general availability on 4 July after a private beta that bridged over $230m across 25-plus chains, so the underlying rails are not new, only the Robinhood Chain destination is.
