summary

0x RFQ uses off‑chain quotes with on‑chain settlement so signed orders execute at a preset price, making trades zero slippage and impossible to front‑run thanks to the txOrigin field that restricts who can submit the transaction. Quotes are gas‑efficient, settled from makers' wallets, and aimed at liquid, hedgeable pairs (WBTC, stablecoins, DeFi blue chips). Practical constraints: it needs sophisticated market‑making infrastructure; current uptake is roughly 40% of DEX volume with about 10–20 professional market makers and is available via 0x API and Matcha.
