1. Project Overview / What is Stable

Stable claims to be the “world’s first blockchain dedicated to stablecoins” — also known as “Stablechain”. The official website describes it as:

“Stable is an institutional-grade blockchain built for stablecoins. … Delivering the rails that global institutions and payment systems can trust.”

Its target scenario: Stablecoins like USDT are already used daily by 500M+ users, yet the underlying “rails” remain fragmented, costly, and slow. The website states:

“500M+ users rely on USDT daily yet the rails are still fragmented, unreliable, and expensive.”

Thus, Stable’s positioning is: Build a blockchain specifically designed for stablecoin payments and settlements, enabling global-scale circulation of digital dollars.

2. Core Features / Key Features

Stable highlights several selling points / modules on its website:

  • Native USDT Settlement — “Use USDT to pay transaction fees and avoid fee rate volatility.”
  • Gasless by Design — “Fees in USDT, with free peer transfers and no surprises.”
  • Enterprise-Ready — “Fast, compliant, and easy to integrate at global scale.”
  • Throughput That Scales — Official target: 10,000+ TPS.
  • EVM Compatible — Seamless migration of Ethereum tools and smart contracts.
  • UX & Finality — Promises sub-second finality, gas-free peer transfers, etc.

3. Target Audience

According to the website, Stable targets the following user groups:

  • Institutions & Enterprises: “Built to meet the performance, compliance, and reliability standards of the world’s largest financial players.”
  • Consumers / Users: “Stable makes digital dollars feel like real money. Fast, simple, and predictable.”
  • Developers: Modular SDK, EVM compatibility, developer-friendly migration environment.

4. Roadmap

The website outlines a phased development plan:

  • Phase 1 (Now): Deploy the world’s first native USDT blockchain infrastructure with real throughput and utility.
  • Phase 2 (Q4 2025): Introduce optimistic parallel execution & StableDB to boost throughput while maintaining second-level settlement.
  • Phase 3 (Q2 2026): Scale to 10,000+ TPS with DAG-based consensus, laying the foundation for future enterprise applications.

5. Highlights & Challenges

Highlights

  • Focuses on stablecoin payment/settlement — a large-scale real-world use case, closer to the real economy than typical crypto chains.
  • Uses USDT as native “Gas” — a direct response to current on-chain fee volatility.
  • Balances users, enterprises, and developers — broad adaptability.

Challenges

  • High barriers: Achieving 10,000+ TPS, global enterprise compliance, and mass adoption of stablecoin payments.
  • High regulatory risk: Stablecoins + large-scale cross-border settlement involve multiple jurisdictions.
  • Fierce competition: Many high-TPS and payment-focused chains exist; failure to quickly build ecosystem and capture use cases risks marginalization.
  • User ecosystem and real-world use cases need time to validate.
