Mayan Finance is a cross-chain swap protocol built on Wormhole messaging that enables fast, MEV-protected swaps between Solana, Ethereum, and 10+ EVM chains — using auction-based order routing (SWIFT) and Wormhole’s Circle CCTP integration (MCTP) to minimize slippage and front-running on cross-chain trades.
Overview
Mayan Finance launched in 2022 as a Wormhole-native cross-chain swap protocol focused on the Solana ↔ EVM corridor, which previously had no efficient native solution. Unlike general-purpose bridge aggregators, Mayan built its own proprietary routing algorithms and introduced MEV protection at the cross-chain level — a novel approach since most bridges execute cross-chain orders transparently and are subject to MEV extraction. Mayan processes swaps through two complementary systems: SWIFT (auction-based routing) and MCTP (Wormhole’s USDC bridging + Mayan DEX swap).
Two Routing Systems
The following sections cover this in detail.
SWIFT (Mayan’s Auction Protocol)
SWIFT is Mayan’s main cross-chain swap mechanism:
- User signs order on source chain specifying: output token, minimum amount, target chain, deadline
- SWIFT auction — solvers (competitive fillers) bid to provide the output on destination chain
- Fast settlement — winning solver delivers tokens immediately (in ~10 seconds) and is repaid via Wormhole messages
- MEV protection — because output amount is specified upfront with a minimum, front-running the solver’s fill on destination chain doesn’t harm the user; the minimum is already committed
Auction dynamics:
- Solvers compete to offer the best output amount above the user’s minimum
- Higher competition → better execution for users
- Solvers profit from the spread between what they deliver and what they eventually recover from bridged tokens
MCTP (Mayan Circle Transfer Protocol)
MCTP uses Wormhole’s integration with Circle’s CCTP (Cross-Chain Transfer Protocol):
- Source chain → burn USDC → Wormhole message → destination chain → mint canonical USDC → DEX swap to output token
- Canonical USDC — avoids wrapped/synthetic USDC issues; always native Circle-issued USDC settlement
- Slower than SWIFT but suitable for larger USDC transfers where canonical safety matters
Solana ↔ EVM Corridor
Mayan’s primary differentiation is the Solana ↔ EVM direction:
- Native Solana DEX liquidity (Jupiter aggregator on Solana side) → cross-chain → EVM DEX
- Most bridge aggregators (LI.FI, Socket) optimize EVM↔EVM; Solana paths were historically inferior
- Mayan became the dominant router for Solana ↔ Ethereum/Arbitrum/Base swaps
MEV Protection in Cross-Chain Swaps
Traditional cross-chain swaps are vulnerable to MEV on the destination chain:
- User bridges Token A to chain B and specifies a DEX swap on arrival
- MEV bots see the pending bridge transaction and front-run the DEX swap on destination chain
- User receives worse price than quoted
Mayan’s SWIFT prevents this by:
- Pre-committing to a minimum output amount on-chain before solver executes
- Solvers operate in a competitive auction — MEV profit opportunity doesn’t come at user’s expense
- The user’s minimum is cryptographically guaranteed; solvers absorb slippage risk
MAYAN Token and Protocol Fees
- MAYAN token — governance token for Mayan Finance DAO
- Fee sharing — a portion of swap fees distributed to MAYAN stakers
- Protocol charges a small basis point fee on each swap routed through SWIFT or MCTP
