What Is Stable (STABLE)? A Purpose-Built Layer 1 for USDT Payments
As stablecoins continue to move from trading instruments to everyday financial infrastructure, the limitations of existing blockchains have become increasingly clear. While USDT has emerged as the dominant digital dollar—powering exchanges, DeFi protocols, and cross-border payments at global scale—the underlying networks it relies on were not designed specifically for high-frequency, low-cost, and reliable stablecoin settlement.
Stable(STABLE) was created to address this gap. Built as a purpose-designed Layer 1 blockchain for USDT payments, Stable rethinks blockchain architecture from the ground up, optimizing every layer for speed, predictability, and real-world usability.
The token is now available for STABLE/USDT spot trading on XT.com, offering users a secure and seamless way to access the digital asset.

What is Stable(STABLE)?
Stable is a Layer1 blockchain purpose-built for stablecoin payments. It provides a settlement layer where value moves in USD₮ with consistent performance, predictable fees, and sub-second finality.
With over $190 billion in circulation and more than 350 million users globally, USDT leads the stablecoin market, powering centralized exchanges, decentralized finance (DeFi), and international payments. Yet, current infrastructure struggles to meet increasing demands for lower costs, higher speeds, and greater reliability. Stable addresses these demands through a scalable, secure, and user-friendly blockchain specifically crafted for USDT’s practical needs. Whether serving retail users in emerging markets or financial institutions handling substantial transaction volumes, Stable delivers an optimal environment to make transactions faster, cheaper, and significantly more efficient.
How Stable(STABLE) Works: Core Mechanism Explained
From the state database, execution, and consensus to USDT-specific optimizations, Stable is designed with a focus on performance, scalability, and reliability. Each component of the stack is optimized to support high-throughput workloads and seamless USDT-native operations across the network.
StableBFT
Initially, Stable Blockchain leverages StableBFT, a customized PoS consensus protocol built on CometBFT, to ensure high throughput, low latency, and strong reliability across the network. To further optimize consensus performance, Stable is planning to decouple data dissemination from the consensus process and implement direct transaction broadcasting to block proposer.
To significantly accelerate consensus, Stable intends to upgrade its protocol to a DAG-based Autobahn. StableBFT, built atop Autobahn, will enable:
- Parallel proposal processing by eliminating the single-leader limitation.
- Faster finality by separating data propagation from final ordering.
- Enhanced resilience against network adversities through robust BFT mechanisms.
Stable EVM
Stable EVM is Stable’s Ethereum-compatible execution layer, enabling seamless interaction with the chain using existing Ethereum tools and wallets. To bridge the gap between the Stable EVM and the StableSDK, Stable EVM introduces a set of precompiles, enabling EVM smart contracts to call into the core chain logic securely and atomically. Stable plans to maximize EVM execution performance through the introduction of StableVM++, which integrates an alternative EVM implementation such as EVMONE and an optimistic parallel execution engine based on Block-STM.
StableDB
Stable improves blockchain speed by fixing a major bottleneck: slow disk storage after each block. It separates state commitment from storage, allowing blocks to process without delay. With MemDB and VersionDB powered by mmap, recent data is handled in-memory while older data is stored efficiently, boosting overall throughput.
High Performance RPC
Even if a blockchain is fast, a slow RPC layer can ruin the user experience. Stable addresses this by rethinking the traditional monolithic RPC design, which suffers from resource contention and poor scalability. Instead, it introduces a split-path architecture that separates operations based on their function, deploying lightweight, specialized RPC nodes for faster response times.Future plans include RPC nodes optimized for EVM view calls and native indexer integration for even faster dApp data access.
Use Cases of Stable
Stable is designed to serve enterprises, everyday users, and developers by providing stablecoin-centric infrastructure with USDT as the core asset. As a blockchain purpose-built for USDT settlement, Stable delivers a reliable, high-performance, and cost-efficient foundation that enhances financial efficiency across different use cases.
For Enterprises: Reliable, USDT-Native Infrastructure
Stable optimizes USDT issuance, settlement, and high-volume transactions, offering institutions a secure and efficient payment and settlement solution.
