Mayan Finance

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:

  1. User signs order on source chain specifying: output token, minimum amount, target chain, deadline
  2. SWIFT auction — solvers (competitive fillers) bid to provide the output on destination chain
  3. Fast settlement — winning solver delivers tokens immediately (in ~10 seconds) and is repaid via Wormhole messages
  4. 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
