Transforming Blockchain for Payments

Stable is a next-generation Layer 1 blockchain that prioritizes financial transaction efficiency. Built with developers and institutions in mind, Stable introduces a novel mechanism: USDT as the native gas token. This addresses one of the most persistent challenges in blockchain development—transaction fee volatility—by providing cost predictability and financial clarity for builders.

With sub-second finality, Stable offers instant transaction settlement, making it especially relevant for applications like payment processors, cross-border remittances, and institutional finance.

The protocol’s strategic backing from Bitfinex and USDT0, along with guidance from Paolo Ardoino (CEO of Tether), ensures alignment with global stablecoin ecosystems, lending both credibility and reach to its broader ambitions.

Why Alchemy?

Alchemy, trusted by leading firms like Visa, Stripe, and VanEck, is the technical backbone behind some of the most demanding Web3 applications. For Stable, choosing Alchemy ensures access to enterprise-grade infrastructure with 99.99% uptime, SOC 2 Type II compliance, and a track record of over $150B+ in onchain transaction support.

Key benefits Alchemy brings to the table include:

• Ultra-Reliable RPC Infrastructure: Global redundancy and always-on performance, essential for uninterrupted payment services.

• Gasless Transaction Orchestration: Seamless integration of Stable’s USDT0-powered fee abstraction layer, removing user friction.

• Robust Developer Tooling: APIs including Websockets, Debug API, and Webhooks to accelerate dApp development and deployment.

Industry Use Cases and Vision

Stable’s architecture is purpose-built to support critical financial infrastructure. Its target verticals include:

• Payments Infrastructure: Enabling real-time, low-cost digital payments via apps like Stable Pay.

• Cross-Border Remittances: Reducing friction for international money transfers.

• DeFi Platforms: Empowering capital-efficient protocols with fast finality.

• Institutional Finance: Supporting high-throughput use cases like payroll and B2B transactions, with features like guaranteed blockspace and privacy tools.

“Payment applications need infrastructure that’s as dependable as the financial systems they’re built to improve.”
– Mike Garland, Head of Product, Alchemy

“Alchemy’s infrastructure powers our gas-free USDT0 mechanism and ensures the guaranteed uptime our ecosystem partners rely on.”
– Brian Mehler, CEO of Stable

The Road Ahead

With this integration, Alchemy continues to cement its reputation as the go-to infrastructure partner for mission-critical blockchain systems. Stable, in turn, stands ready to redefine how global value moves—faster, cheaper, and more reliably than ever before.

As Stable’s public testnet and pre-deposit campaign approach, developers and institutions alike are encouraged to begin exploring the platform’s capabilities.

Welcome to Stable — the first blockchain designed exclusively for stablecoins, powered by USDT, the world’s most used digital dollar. With over $150 billion in circulation and more than 350 million global users, USDT has become the backbone of crypto markets, DeFi, and international payments. Yet despite its ubiquity, the infrastructure it runs on hasn’t kept pace with growing demand.

Fees remain unpredictable, transactions aren’t always fast, and users are often forced to juggle volatile gas tokens just to move stablecoins. Enterprises face scalability bottlenecks and compliance hurdles, while developers wrestle with unnecessary complexities.

Stable was created to change that. It is a high-throughput Layer 1 blockchain purpose-built to move stablecoins at scale, enabling gas-free transfers, sub-second finality, ultra-low costs, and enterprise-grade features.

In short, the world’s most used asset finally has a chain worthy of it.

What is Stable?

Stable is the first Stablechain — a dedicated payments Layer 1 where USDT is both the settlement and gas token. It’s optimized from the ground up to serve stablecoin users, enterprises, and developers.

Key Innovations:

• USDT as Native Gas: No more juggling volatile tokens. Users pay fees directly in USDT. Peer-to-peer USDT transfers are even gas-free.
• Sub-Second Finality: Payments finalize instantly, suitable for micropayments and large institutional settlements alike.
• Optimized for Scale: Handles thousands of transactions per second with minimal cost, consistently under a fraction of a cent.
• Enterprise Features: Confidential transfers, guaranteed blockspace, and aggregated large-scale USDT settlement.
• Developer-Friendly: Fully EVM compatible with specialized SDKs, APIs, and integration tools.

Stable is not just another general-purpose blockchain. It’s custom-engineered for USDT, solving the inefficiencies that limit adoption today.

The Problems Before Stable

As stablecoins gain prominence, existing blockchains show their cracks:

• Unpredictable Fees: Gas costs often spike, making frequent low-value transactions impractical.
• Enterprise Friction: Businesses face inconsistent speeds, a lack of privacy solutions, and poor integration with legacy systems.
• User Confusion: Newcomers must hold multiple assets just to send a stablecoin.
• Limited Access: In underserved regions, high remittance fees and banking barriers keep users excluded.
• Developer Complexity: General-purpose chains don’t provide stablecoin-specific infrastructure, complicating dApp development.

Stable was built to address these pain points directly.

After Stable: A Tailored Ecosystem for USDT

Stable transforms the stablecoin experience with dedicated infrastructure and specialized tooling.

For Users:

• Gas-Free Transfers: Send USDT peer-to-peer without paying gas.
• Intuitive Wallet: The Stable Wallet provides a web2.5-like experience with debit/credit card integration.
• Cross-Border Ready: Seamless global transfers at a fraction of the cost of traditional remittances.
• Consistent Reliability: Transactions finalize in under a second, every time.

For Enterprises:

• Guaranteed Blockspace: Reserve dedicated capacity for consistent throughput.
• Confidential Transfers: Regulatory-compliant privacy for sensitive operations.
• High-Volume Aggregation: Efficient large-scale USDT settlements.
• Integration Tools: APIs and SDKs to plug Stable directly into existing systems.

For Developers:

• 100% EVM Compatible: Deploy Ethereum contracts seamlessly.
• Specialized SDKs: Tailored to stablecoin use cases.
• Stable EVM: Precompiles for deeper integration between dApps and chain logic.
• Future-Proof: Roadmap includes DAG-based consensus, transfer aggregation, and enhanced scalability.

• Enterprise Features (Upcoming) – Confidential transfers and guaranteed blockspace allocation.

Real-World Applications

Stable isn’t just theoretical—it’s designed for everyday utility and global adoption.

• Financial Services: Power savings, lending, and settlement systems built on stablecoins.
• Remittances: Enable instant, near-zero-cost cross-border payments.
• Merchant Solutions: Accept USDT payments without third-party processors.
• Consumer Payments: Spend USDT directly with debit and credit card integrations.

By removing the friction of gas tokens, high fees, and inconsistent infrastructure, Stable makes digital dollars as usable as physical dollars—only faster and cheaper.

Roadmap and Vision

Stable’s development is rolling out in phases, each designed to expand utility and scalability:

• Phase 1: High-performance L1 with sub-second finality and EVM compatibility.
• Phase 2: Enterprise adoption with confidential transfers and guaranteed blockspace.
• Phase 3: Expanded real-world integrations with payments, remittances, and merchant solutions.
• Phase 4: Advanced consensus (DAG-based) and transfer aggregation for massive scale.

The endgame? A dedicated, global stablecoin infrastructure that unlocks the full potential of USDT for users, institutions, and developers alike.

Conclusion

Stable is the first blockchain purpose-built for stablecoins, creating a home for USDT that is fast, cost-efficient, secure, and developer-friendly.
