Alternative comparison
TL;DR: 0x is the dex aggregation infrastructure protocol powering matcha, metamask swap, and hundreds of dapps. If you are looking for a 0x alternative with lower fees, gasless execution, MEV protection, and surplus returned to you, Orkid is the strongest option on Base, Ethereum, and Unichain.
Why switch
Protocol fee is embedded in the route — not transparent to the end user
Gasless mode charges 25 bps — 2.8x what Orkid charges (9 bps)
Orkid addresses these issues with a transparent 9 bps flat fee, gasless execution via Permit2, patent-backed MEV detection, and full surplus return to the user.
Top alternative
Orkid charges 9 bps vs 0x Gasless at 25 bps. On a $10,000 swap, that is $9 vs $25. Orkid returns surplus to you — 0x does not. Same gasless experience, lower fee, more transparent.
What 0x does well
0x is not a bad product. It has real strengths:
The question is whether those strengths matter more to you than transparent pricing, gasless execution, MEV protection, and surplus return.
Other alternatives
DEX
The largest decentralized exchange by volume, with V2, V3, and V4 pools.
Fee: 5-100 bps depending on the pool. V3 concentrated liquidity pools can be as low as 1 bp; V2 is flat at 30 bps.
Orkid vs Uniswap →Wallet Swap
The in-wallet swap feature powered by 0x, charging 0.875% per swap.

Orkid vs MetaMask Swap →Aggregator
The most established DEX aggregator with Fusion mode for gasless, MEV-protected swaps.
Fee: Classic mode: 0 bps platform fee, you pay pool fees + gas. Fusion mode: gasless, fee embedded in the Dutch auction spread.
Orkid vs 1inch →Aggregator
Batch auction DEX aggregator with coincidence of wants matching and MEV protection.
Fee: 0 bps protocol fee. Revenue comes from the batch auction spread and coincidence of wants matching.
Orkid vs CoW Swap →Ready to switch
If you swap through any 0x-powered interface (Matcha, MetaMask Swap, etc.), Orkid uses the same Permit2 signature flow. Same wallet, lower fees, surplus returned.
