Stable (also known as Stablechain) is the world’s first specialized Layer 1 network built specifically for USDT operations. The project enables instant, transparent, and near-zero-cost transactions, eliminating the need for external tokens to pay for gas, and providing infrastructure suitable for both everyday users and large enterprises.

1. Overview and Context of Stablechain
Stablechain is a high-performance Layer 1 blockchain network developed with the participation of Bitfinex and Tether. It focuses on supporting the world’s most widely used stablecoin — USDT. A key feature of the network is that all transaction fees are paid directly in USDT, eliminating the need for a separate gas token. This greatly simplifies user interaction with the blockchain and lowers the entry barrier.
With sub-second finality and zero-fee peer-to-peer transfers, the network offers a more convenient and predictable alternative to traditional blockchain solutions, where fees are often volatile and depend on network load.
In July 2025, the project raised $28 million in a seed funding round led by Bitfinex and Hack VC, with participation from Franklin Templeton, Castle Island Ventures, KuCoin Ventures, and Tether CEO Paolo Ardoino. This level of institutional interest highlights the strategic relevance of the project.
Despite USDT surpassing $1 trillion in daily transactional volume, the infrastructure for stable digital assets remains fragmented and costly. Stablechain addresses these shortcomings by offering a purpose-built environment for fast, affordable, and stable USDT transactions.
2. Technical Architecture and Innovations
Stablechain uses a delegated Proof-of-Stake consensus mechanism called StableBFT, which delivers high throughput and sub-second block finality. The network is fully compatible with the Ethereum Virtual Machine (EVM), making it developer-friendly and allowing for easy porting of smart contracts.
One of the core features is the use of an enhanced stablecoin version — USDT0, based on the Omnichain Fungible Token (OFT) standard. It is automatically converted into gasUSDT for paying transaction fees. At the same time, regular peer-to-peer USDT0 transfers remain gasless thanks to the implementation of EIP-7702 and Account Abstraction. These technologies enable seamless and transparent transfers without intermediary tokens.
The technical infrastructure of Stablechain is designed for performance and scalability. Below is a table of key architectural components:
| Component | Description |
|---|---|
| StableBFT | Delegated consensus algorithm that provides sub-second finality and resilience against network disruptions. |
| USDT0 and gasUSDT | OFT-based version of USDT used for transfers; automatically converted into gasUSDT for paying fees. |
| StableDB | State storage system using MemDB and VersionDB for fast data processing. |
| StableVM++ | Optimized EVM version with parallel transaction execution for increased throughput. |
| Optimized RPC Layer | Provides fast communication between clients and nodes, reducing latency. |
| Account Abstraction (EIP-7702) | Enables gasless USDT transfers and flexible account logic. |
Upcoming feature updates from the Stablechain team include:
- USDT transfer aggregators — for optimizing large-volume transactions.
- Guaranteed blockspace — reserved space for enterprise users and payment providers.
- Private transfers — privacy-enabled functionality without compromising regulatory compliance.
This architecture allows Stablechain to overcome the bottlenecks of traditional blockchains, ensuring high speed, security, and scalability, while maintaining simplicity and accessibility for end users.
3. Use Cases and Target Audiences
Stablechain delivers a versatile infrastructure for working with USDT — equally suitable for everyday users, enterprises, and developers. With its fast confirmations, gasless peer-to-peer transfers, and native USDT gas payments, the network supports a broad range of practical applications.
Key use cases of Stablechain include:
- Simplified transfers for users — no need to hold ETH or other tokens; fees are paid in USDT and transfers are free.
- Intuitive social interface — Web2.5 wallet with social login and human-readable Stable Names for easier fund management.
- Enterprise blockspace access — reserved network bandwidth for high-volume partners and payment platforms.
- Large-scale USDT transfers — aggregated transactions with minimal costs.
- Private and compliant operations — transaction privacy tools aligned with regulatory standards.
- Web3 app development — full EVM compatibility allows seamless migration of dApps.
- Developer tools and analytics — SDKs, APIs, and infrastructure for building wallets and payment systems.
- Financial inclusion — enabling access to stablecoin transfers in regions with limited banking infrastructure.
In this way, Stablechain does more than address high fees and UX friction — it establishes a new benchmark for user experience in blockchain. It combines accessibility for individuals, reliability for enterprises, and flexibility for developers, making it a solid foundation for future wallets, corporate payment systems, and global financial services.
4. Platform Development Roadmap
The development of Stablechain is structured in clear phases, each aimed at scaling the network’s capabilities. The first phase, already launched, introduced core features such as sub-second finality, fee-free USDT transfers, and native gas payments in stablecoins. This foundation supports a frictionless experience for both emerging markets and everyday users.
The second phase, expected in Q4 2025, will implement optimistic parallel execution to further increase throughput and reduce congestion. This phase also includes the introduction of StableDB — a custom data layer built with MemDB and VersionDB to enable high-speed and resilient state storage.
The final stage in the current roadmap is set for Q2 2026 and will transition the network to a novel DAG-based consensus called Autobahn. This architecture is designed to scale beyond 10,000 transactions per second and enable the processing of institutional-scale financial flows. Alongside this, the infrastructure will be further expanded to serve enterprise partners and global payment systems.
Through this step-by-step execution of its roadmap, Stablechain is evolving from a foundational Layer 1 into a full-fledged financial platform, ready for integration into the global payments ecosystem and capable of challenging traditional finance on its own terms.
5. Conclusion
Stablechain introduces a new paradigm in blockchain infrastructure — one that revolves around stable assets. By enabling USDT-based gas payments, fee-free peer-to-peer transfers, EVM compatibility, and ultra-fast confirmations, the network directly addresses long-standing barriers such as complexity, high fees, and poor UX. With backing from top-tier investors and a layered technical stack, Stablechain is well-positioned to become the foundation for next-generation financial applications.
Amid growing global demand for stable and accessible payment rails, Stablechain acts not only as a technical innovation but also as a bridge between legacy financial systems and the Web3 economy. Its ease of integration, transaction efficiency, and real-world focus make it a promising platform for retail, cross-border, and institutional use.
