Sky Protocol enters the Cosmos ecosystem via Althea’s iFi DEX, enabling native access to USDS and sUSDS across the Interchain.

Sky Protocol’s flagship savings stablecoins, sUSDS and USDS, are now available on the Interchain via the Althea L1 iFi DEX. The Interchain, a fast-growing network of connected blockchains in the Cosmos ecosystem, lets tokens and data move freely across many chains. With over $9 billion in combined USDS and sUSDS supply, USDS is the third-largest stablecoin, and for the first time, it’s available natively across Cosmos.

This launch expands access to high-performance, decentralized stablecoins backed by real-world yield and seamlessly interoperable with major assets, such as USDC. Today, developers and operators can start integrating USDS into DeFi platforms, infrastructure payments, and machine-to-machine applications across the Interchain, marking a significant milestone for both infrastructure finance and cross-chain DeFi.

Althea has deep roots in stablecoin innovation. A long-time collaborator in the Sky (formerly MakerDAO) ecosystem, Althea pioneered the use of on-chain stables in telecom and infrastructure payments deploying DAI in real-world use cases long before stablecoins were household names.

The Infrastructure Finance Decentralized Exchange (iFi DEX) is the native DEX of the Althea L1 blockchain, expanding on Althea’s track record of stablecoin adoption. It provides both a decentralized exchange for the ecosystem and a settlement layer purpose-built for the emerging machine economy, utilities, and network infrastructure.

Designed for savings, long-term liquidity, and programmable payments, USDS offers a capital-efficient and reliable medium of exchange backed by real-world assets. Whether you're powering smart city sensors or settling renewable microgrid transactions, it delivers both stability and sustainable yield.

“Decentralized infrastructure requires capital that moves as fast as the network,” said Deborah Simpier, Co-Founder of Althea. “With USDS on Althea, routers, sensors, and grid controllers can transact seamlessly using stable, on-chain payments designed for automation and operational efficiency.”

Unlocking a $3+ Trillion Market

The integration with Althea brings Sky Protocol’s long-established lending and stable protocol to a blockchain purpose-built for infrastructure finance. With Althea’s focus on the $3 trillion global telecom and infrastructure market, this milestone opens new pathways to tokenize, fund, and scale critical infrastructure projects around the world.

Where DeFi Meets iFi

With this launch, Sky Protocol and Althea combine decentralized finance (DeFi) and infrastructure finance (iFi) into one seamless experience:

• Users can trade USDS, sUSDS, USDC, ETH, BTC, and other tokens across native EVM chains via the Althea L1 iFi DEX, ensuring smooth onboarding and cross-chain compatibility between the Cosmos and Ethereum ecosystems.
• With gasless transactions, autonomous devices like smart meters, routers, and sensors can interact directly with the DEX using USDS without paying gas fees.
• sUSDS brings the power of savings to native machine-to-machine (M2M) payments, thanks to Sky’s integration with Althea’s machine-to-machine payment protocols.

Developers and operators can begin integrating USDS into Interchain-native applications immediately via Althea’s iFi DEX smart contracts and liquidity pools.

About the Sky Protocol

Sky, formerly known as Maker, is a decentralized protocol with the Sky stablecoin USDS at its core. The protocol features Sky tokens (USDS, SKY), the Sky Savings Rate (SSR), Sky Token Rewards (STRs), SKY Staking, and more.

Sky Protocol is governed by a decentralized community and structured around two foundational frameworks: the Sky Agent Framework, which enables autonomous on-chain agents and allows founders to create Sky Stars, independent protocol units designed to foster fast-moving innovation at the margins of the ecosystem; and the Sky Atlas, a living, comprehensive set of governance rules developed through proposals and decentralized voting.
