Mento Is Bringing Onchain FX to the Monad Ecosystem

Foreign exchange is the world’s largest financial market, processing over $9.6 trillion in daily volume. Yet despite this scale, onchain FX has lagged behind other financial primitives. Adoption has been constrained by fragmented liquidity, unreliable pricing, and execution models that were never designed for real-world currencies.
As stablecoins mature into widely used financial rails, reliable onchain FX becomes a critical piece of missing infrastructure. Payments, treasury management, cross-border commerce, and global DeFi applications require reliable currency exchange.
Mento is bringing institutional-grade FX infrastructure to the Monad ecosystem whose high-performance execution environment creates the conditions for FX to finally scale onchain.
Introducing Mento
Mento is the onchain FX liquidity layer, providing decentralized infrastructure for predictable pricing and tight execution across global currencies. Today, Mento supports 15 currencies, has processed $18.5B in trading volume in 2025, and powers stablecoin swaps for over 12M+ Opera MiniPay users.
Purpose built for real-world currency exchange, Mento enables stablecoin-based FX markets that prioritize reliability, transparency, and capital efficiency. All core requirements for financial applications operating at scale.
By expanding to Monad, Mento is laying the foundation for reliable onchain FX markets within the ecosystem. This expansion is supported by Mento’s integration with Wormhole, enabling secure cross-chain connectivity as FX markets grow across ecosystems.
Fixed-Price FX: A New Primitive for Monad
Introduced with Mento V3, the Fixed-Price FX model enables predictable, reference-rate execution for real-world currency markets. Rather than relying on volatile AMM curves not built for the FX market, Fixed-Price FX pools track real-world reference rates using oracle-based pricing. Chainlink helps to deliver consistent execution for non-USD stablecoins.
This approach is designed for use cases that demand pricing stability, including:
- Cross-border payroll, invoicing, and treasury workflows requiring tight spreads and predictable settlement;
- Fintech apps that need stable, real-time currency conversions across multiple markets;
- DeFi protocols integrating low-slippage FX pairs for yield strategies, lending markets, and automated rebalancing.
For Monad developers this unlocks a natively composable FX primitive, pegged to oracle-driven rates and deployable across multi-currency flows, that can be embedded into smart contract systems for trading, settlement, and payment applications.
Why Monad
FX markets are defined by tight spreads and fast-moving reference rates. Execution quality depends on low latency, fast finality, and the ability to update quotes and rebalance liquidity continuously. Monad’s high-throughput EVM environment is exactly built for this kind of always-on market activity, where pricing can stay current and settlement can happen quickly and predictably.
By deploying on Monad, Mento brings institutional-grade FX execution onchain, enabling high-velocity trading, efficient routing, and deep liquidity formation for real-world currency pairs.
Multichain FX Architecture
Mento’s expansion to Monad is part of a broader multichain strategy. Stablecoin issuance and risk management remain anchored on Celo, while liquidity and market formation extend to high-performance environments like Monad, optimized for distribution, trading, and deep liquidity.
This architecture allows Mento to scale onchain FX across ecosystems without fragmenting liquidity or compromising pricing integrity. Over time, Mento will continue to expand to additional chains, bringing reliable onchain FX wherever builders and users demand it.
What to Expect
Mento’s deployment on Monad will begin with a GBPm / USDm trading pair, one of the most actively traded FX pairs globally. Additional currencies are expected to follow as liquidity and demand grow.
Incentivized liquidity programs and ecosystem collaborations will accompany the launch to support early market formation and ensure high execution quality.
More details on timing, participation, and ecosystem programs will be shared ahead of deployment.
