On July 1, 2025, Stable launched  Stablechain, the first-ever dedicated Layer 1 blockchain powered exclusively by Tether’s USDT stablecoin. This pioneering blockchain, simply branded as Stable, aims to transform the way stablecoins are used by offering ultra-fast, low-cost, and reliable transactions tailored specifically for USDT payments, addressing long-standing inefficiencies in the stablecoin ecosystem.

A Blockchain Built for Stablecoins

Stablechain uses USDT as its native gas and settlement token, effectively eliminating unpredictable transaction fees and slow settlement times that often plague users and institutions alike. This design choice simplifies the user experience by allowing payments and fees to be settled directly in USDT, the world’s most widely used stablecoin, which currently settles over $100 billion daily. Stablechain offers sub-second block finality, ensuring near-instant transaction confirmations, and is fully Ethereum Virtual Machine (EVM) compatible, allowing developers to deploy decentralized applications (dApps) with familiar tools and frameworks. This compatibility also means that existing Ethereum-based dApps can migrate or integrate with Stablechain seamlessly, enhancing the stablecoin payment infrastructure.

Gas-Free Transfers with USDT0 Integration

A standout feature of Stablechain is its integration with USDT0, a decentralized version of USDT powered by LayerZero technology. Transactions involving USDT0 are gas-free, further reducing costs and friction for users. This innovation is particularly appealing for peer-to-peer transfers and cross-border payments, where minimizing fees and delays is critical.

Institutional-Grade Features

Stablechain is not just designed for retail users but also caters to institutional needs. It offers guaranteed blockspace allocation, batch transaction processing, and confidential transfers that balance privacy with regulatory compliance. These features make Stablechain attractive for enterprises seeking scalable, secure, and compliant stablecoin payment solutions. The native Stable Wallet enhances user convenience by supporting social login, debit/credit card integration, and human-readable wallet names, making it easier for users to interact with the blockchain without the usual complexity associated with crypto wallets.

Roadmap and Ecosystem Growth

Stable plans to roll out further innovations in upcoming phases, including optimistic parallel execution to boost transaction throughput, additional enterprise tools, and comprehensive developer SDKs to foster a vibrant ecosystem around Stablechain. These developments aim to accelerate adoption and enable new use cases in payments, decentralized finance (DeFi), and beyond.

Backing and Industry Support

The project is backed by Bitfinex and the decentralized USDT0 community. Bitfinex also led a $3.5 million funding round in 2024 for Plasma, a sidechain focused on reducing USDT transaction fees, underscoring the firm’s commitment to enhancing stablecoin infrastructure. Tether CEO Paolo Ardoino has publicly congratulated the Stable team on their innovation, highlighting the immense potential for stablecoins in payments, remittances, and trading. Ardoino’s endorsement signals strong industry confidence in Stablechain’s vision and technology.

Market Context

Stablechain represents a significant leap forward in the stablecoin and blockchain ecosystem. By creating a dedicated Layer 1 blockchain powered by USDT, Stable addresses key pain points such as volatile fees, slow settlements, and complex user experiences. The launch of Stablechain comes at a critical moment as U.S. lawmakers move closer to passing the GENIUS Act, which aims to regulate stablecoins. This legislation could bring more clarity and legitimacy to stablecoin operations, making Stablechain’s timing especially strategic for the sector.
