Matcha: The 0x DEX Aggregator With Gasless Swaps, Reviewed
Matcha reviewed: 0x's clean DEX aggregator with RFQ liquidity and gasless swaps across many chains. How it works, fees, safety, and who it's for.
Table of contents
Most DEX aggregators optimize for price and forget the human using them. Matcha, built by the 0x team, does both: it routes across DEXs and professional market makers for a strong price, and wraps it in the cleanest interface in DeFi, with gasless swaps so you do not need native gas on a fresh chain. If you want swapping to just feel easy without giving up the rate, Matcha is the one. Here is how it works and how to start in two minutes.
What is Matcha?
Matcha is a DEX aggregator built by the 0x team. It routes each swap across many DEXs and professional RFQ (request-for-quote) market makers to find the best price, then presents it in one of the cleanest, most beginner-friendly interfaces in DeFi. The RFQ flow is a real differentiator: professional market makers stream quotes into 0x, and Matcha routes to them when they beat on-chain pools, which can mean less slippage on larger trades.
On supported chains, Matcha offers gasless swaps, deducting the fee from the tokens you are trading so you do not need the chain's native gas token to transact.
How Matcha works
- You set the swap: chain, input token, output token, and amount. Matcha returns the best quoted amount received.
- The router compares DEXs and RFQ market makers, routing to whichever gives the best fill, splitting where useful.
- Your wallet signs and the swap settles through 0x's contracts. On gasless swaps, a relayer submits the transaction and the fee comes from the token.
Typical result: a strong price with RFQ liquidity, a clean flow, and the option to swap without holding native gas on supported chains.
Why Matcha wins
- RFQ market-maker liquidity. 0x's professional quote flow can beat on-chain pools, reducing slippage on size.
- Gasless swaps. Transact on a fresh chain without pre-funding native gas.
- The cleanest UX. Approachable enough for newcomers, precise enough for pros, with clear price-impact and route detail.
- 0x settlement. Audited, widely used contracts behind every trade.
When to reach for something else: quote another aggregator (Odos, 1inch, KyberSwap) on large trades and take the better number, and note gasless availability varies by chain.
Security
Matcha is non-custodial and settles through 0x's audited, widely used contracts, so your funds stay in your wallet until a swap executes. 0x is one of the longest-running pieces of DeFi infrastructure. The standing risk is token approvals, common to every aggregator, so review what you approve and revoke unused allowances (a tool like Revoke.cash helps). As always, verify the official app URL and start with a small swap on a chain you have not used it on.
How to get started
- Open the app and connect a self-custody wallet.
- Pick the chain and tokens to swap.
- Review the quote, the amount received and price impact, and whether the swap is gasless, then confirm.
- Start small on a new chain to confirm everything behaves as expected.
Final verdict
Matcha is the aggregator to reach for when you want a clean, reliable swap without sacrificing price. RFQ market-maker liquidity, gasless swaps on many chains, and 0x settlement make it both approachable and capable, all non-custodial. Quote a second aggregator on large trades and take the better output, but for everyday swapping with the least friction, Matcha is hard to beat. Try your next swap through it and enjoy how little it asks of you.

What are Matcha gasless swaps?
On supported chains Matcha can execute a swap without you holding the chain's native gas token: the fee is deducted from the tokens you are trading and a relayer submits the transaction. It is convenient when you land on a new chain with only the asset you bridged in.
Matcha vs 1inch, which is better?
Both aggregate DEXs plus RFQ liquidity; the best price varies by pair and size. Matcha is prized for its clean UX and 0x's RFQ market-maker flow, while 1inch has Pathfinder and Fusion. Quote both and take the higher amount received for your trade.
