CoW Swap vs. Mayan
Rift Research
Last updated
TLDR: CoW Swap is a batch-auction DEX built on CoW Protocol. Mayan is a fast cross-chain swap protocol. Consider CoW Swap when you want MEV-protected swaps and coincidence-of-wants matching. Consider Mayan when you need a fast EVM ↔︎ Solana or similar corridor. Confirm the live winner on rates.gg.
What each protocol is
CoW Swap. CoW Swap is the primary interface for CoW Protocol. Users sign intents. Solvers batch them, search on-chain and off-chain liquidity, and settle in a combinatorial auction designed to protect against MEV. Opposite orders can match peer-to-peer (a coincidence of wants). Official docs: CoW Protocol Docs. App: swap.cow.fi.
Mayan. Mayan routes cross-chain swaps through Swift (intent auction), MCTP (Circle CCTP plus Mayan auction), and Wormhole Swap. It is widely used on EVM ↔︎ Solana and similar corridors. Official docs: Mayan Docs. App: mayan.finance.
Short version
| Dimension | CoW Swap | Mayan |
|---|---|---|
| Role | Batch-auction DEX on CoW Protocol | Fast cross-chain swap protocol |
| Fee | Solver competition pricing; surplus-aware execution | Priced into the auction / route quote |
| Coverage | Ethereum and other CoW-supported EVM networks; cross-chain swaps exist on the UI | Solana, Ethereum, Base, Arbitrum, Optimism, BNB Chain, Sui, HyperEVM, Monad and others listed in Mayan docs |
| Settlement | Batch auction through the CoW settlement contract | Native on the destination; path depends on Swift, MCTP or Wormhole |
| Trust model | Non-upgradeable vault relayer and settlement contracts; solver competition | Intent auction plus the messaging layer used on that path (CCTP or Wormhole) |
| Good fit for | MEV-protected swaps and coincidence-of-wants matching | Fast EVM ↔︎ Solana and related corridors |

Where each fits
CoW Swap may fit when:
- MEV protection and batch-auction execution matter
- The trade is inside CoW’s supported environment
- A coincidence of wants in the batch can improve the net price
Mayan may fit when:
- Solana is on one side of the route
- You want an intent fill rather than an AMM curve
- MCTP can reuse CCTP for a USDC leg
Key differences
CoW Swap and Mayan should be compared on the job you need to complete: the input asset, destination asset and chain, trade size, execution method and custody assumptions. They may overlap on some routes and complement each other on others. A broader chain list or faster advertised fill does not establish a better net rate. Compare executable quotes in the same window, including gas and every underlying step.
When to use which
- Use CoW Swap when you want MEV-protected swaps and coincidence-of-wants matching.
- Use Mayan when you need a fast EVM ↔︎ Solana or similar corridor.
- If both can quote the same route, take the better net output after fees, time and settlement type. Check that print on rates.gg.
FAQ
Which is cheaper, CoW Swap or Mayan?
Neither has a universal price advantage. CoW Swap: Solver competition pricing; surplus-aware execution. Mayan: Priced into the auction / route quote. Compare executable quotes for the same size, destination and time window, including gas, underlying venue costs and any extra transfer. Expected output and minimum received are different figures; compare like with like.
Is CoW Swap a substitute for Mayan?
Only on overlapping pairs and chains. When both can quote the same route, take the better net output after fees and time. When only one supports the asset or chain, that one is the only option.
Where are the official CoW Swap and Mayan docs?

Get the Best of Both With Rift
Rift is a strong alternative to choosing between CoW Swap and Mayan. It brings routes from both together with additional venues on supported pairs, comparing available quotes to find the best net execution for your order. You get the strengths of both through one API.
Rift adds no router fee and uses secure hardware enclaves to enforce noncustodial execution. Underlying venue fees, spreads and network costs still apply, and availability depends on the asset, chain and order size. The live quote shows the route and expected output.
