Matcha
6.9/10 total
The consumer front end for 0x's routing infrastructure, requiring a wallet connection and nothing else. Its marketing claims zero-fee swaps across seventeen networks, but its own help centre documents a 0.25% taker fee on most pairs and up to 0.4% on non-stablecoin cross-chain swaps, so treat the headline as applying to stablecoin pairs only. It also keeps positive slippage rather than returning it, which is the difference that matters when comparing against a router that refunds surplus.
Scores
Weights are published in the method and applied identically to every entry.
For
- No account, no email and no verification to trade
- On-chain settlement, so funds are never custodied by Matcha
- Stablecoin-to-stablecoin swaps genuinely are free of a Matcha fee on all supported chains
- Fee schedule is published in the help centre with per-mode and per-pair detail
- 0x routing has been in production since 2018, which is a long record for this category
Against
- The front page advertises zero fees while the help centre documents 0.25% on most pairs, which is a real mismatch a reader can be caught by
- Captures trade surplus when execution beats the quote instead of returning it to the trader
- Cross-chain non-stablecoin swaps cost 0.4%, high for an on-chain aggregator
- Every trade is public on-chain and the hosted front end sees your IP and wallet address
- No onion service, no no-JavaScript path, and the front end is not open source
Agent access 6/10
Programmatic access runs through the 0x Swap API, which requires an account and an issued API key with a metered plan. The key requirement is the only thing standing between an agent and unattended quoting and execution.
Reported separately and not counted in the total. It measures what an autonomous agent can do unattended, not whether the service is safe to use.
Fees
0.25% typical
The site headline says zero fees, but the help centre states a 0.25% taker fee on most pairs, zero on stablecoin-to-stablecoin, 0.04% on stablecoin cross-chain and 0.4% on other cross-chain pairs. Matcha also captures trade surplus when execution beats the quote, guaranteeing only that you receive at least the quoted amount.
