What is Stable (STABLE)? A Layer 1 blockchain specifically designed for USDT payments.

As stablecoins evolve from trading instruments into everyday financial infrastructure, the limitations of existing blockchains become increasingly clear. While USDT has become the dominant digital dollar—powering exchanges, DeFi protocols, and cross-border payments globally—the underlying network it relies on was not designed for high-frequency, low-cost, and reliable stablecoin settlements.

Stable (STABLE) was created to fill this gap. As a Layer 1 blockchain specifically designed for USDT payments, Stable rethinks the blockchain architecture from the ground up, optimizing each layer for speed, predictability, and real-world availability.

The STABLE token is now available for spot trading on XT.com, providing users with a safe and seamless way to acquire this digital asset.

What is Stable (STABLE)?

Stable is a Layer 1 blockchain built specifically for stablecoin payments. It provides a settlement layer that enables value to flow in USD₮, maintaining consistent performance, predictable fees, and sub-second final confirmation.

Globally, USDT boasts a circulating supply exceeding $190 billion and over 350 million users, placing it at the forefront of the stablecoin market and supporting centralized exchanges, decentralized finance (DeFi), and international payments. However, current infrastructure struggles to meet the growing demand for lower costs, higher speeds, and greater reliability. Stable addresses these needs with a scalable, secure, and user-friendly blockchain specifically built for USDT's real-world use cases. Whether serving retail users in emerging markets or financial institutions handling large transaction volumes, Stable provides a superior environment for faster, cheaper, and significantly more efficient transactions.

How Stable Works: Understanding the Core Mechanisms

From its state database, execution, and consensus mechanisms to specific optimizations for USDT, Stable's design focuses on performance, scalability, and reliability. Every component of its technology stack is optimized to support high-throughput workloads and enable seamless native USDT operations across the network.

StableBFT

In its initial phase, the Stable blockchain employs StableBFT—a customized Proof-of-Stake (PoS) consensus protocol built on CometBFT—to ensure high throughput, low latency, and strong reliability across the network. To further optimize consensus performance, Stable plans to decouple data propagation from the consensus process and implement a mechanism that allows transactions to be directly broadcast to the block proposer.

To significantly accelerate the consensus process, Stable also plans to upgrade its protocol to a DAG-based Autobahn architecture. StableBFT, built on top of Autobahn, will implement:

• Parallel proposal processing is achieved by eliminating the single-leader constraint;
• By separating data propagation from final sorting, faster final confirmation is achieved;
• Leveraging a robust BFT mechanism, it provides enhanced resistance to attacks and interference in complex network environments.

Stable EVM

Stable EVM is Stable's Ethereum-compatible execution layer, enabling users to seamlessly interact with the chain using existing Ethereum tools and wallets. To bridge the gap between Stable EVM and StableSDK, Stable EVM introduces a set of precompiles, allowing EVM smart contracts to call the core logic of the underlying chain in a safe and atomic manner.

In terms of performance, Stable plans to maximize the execution efficiency of the EVM by introducing StableVM++. StableVM++ will integrate alternative EVM implementations such as EVMONE and combine them with a Block-STM-based OP parallel execution engine to significantly improve execution performance.

StableDB

Stable improves overall performance by addressing a key bottleneck in blockchain—slow disk storage after each block is written. Its core idea is to separate state commits from the storage process, freeing blocks from the latency of disk writes during processing.

With the help of mmap-based MemDB and VersionDB, the latest data can be processed efficiently in memory, while historical data is efficiently persisted, thereby significantly improving the overall throughput.

High-performance RPC

Even if the blockchain itself is fast enough, a slow RPC layer can still severely disrupt the user experience. Stable addresses this issue by redesigning the traditional monolithic RPC architecture—an architecture that typically suffers from severe resource contention and insufficient scalability.

Stable introduces a split-path architecture, which breaks down operation processes according to different functions and deploys lightweight, dedicated RPC nodes to achieve faster response times. Future updates will include RPC nodes optimized for EVM view calls and integration of a native indexer to further accelerate data access for dApps.

Application scenarios of Stable

Stable uses USDT as its core asset and builds its infrastructure around stablecoins, aiming to serve businesses, ordinary users, and developers simultaneously. As a blockchain specifically designed for USDT settlement, Stable provides a reliable, high-performance, and cost-effective underlying foundation, helping to comprehensively improve financial efficiency across various scenarios.

For enterprises: Reliable USDT native infrastructure

Stable is deeply optimized for USDT issuance, settlement, and high-frequency, high-value transactions, providing institutions with a secure and efficient payment and clearing solution. Enterprise-level features include:

• Guaranteed block space (coming soon) will maintain stable transaction latency even during network congestion;
• High-throughput transaction processing capabilities achieved through transfer aggregation;
• A robust and secure architecture for critical financial operations.

The upcoming confidential transfer feature will help institutions protect transaction privacy while meeting regulatory requirements such as anti-money laundering (AML) and auditing.

In addition, Stable supports a variety of practical institutional applications, including stablecoin-based payment solutions and merchant terminals, enabling merchants to accept USDT payments directly with predictable performance and extremely low operating costs.
