StableChain: The Birth of a Dedicated Blockchain for the Stablecoin Era

From Stablecoins to a Dedicated Blockchain Infrastructure

In 2025, Tether—the world’s largest stablecoin issuer—partnered with Bitfinex to launch StableChain, a blockchain built specifically for stablecoin transactions. This initiative marks a new chapter for digital assets, shifting from reliance on multipurpose blockchains like Ethereum and TRON toward a native infrastructure optimized for stability, speed, and payment efficiency.

Unlike general-purpose blockchains, StableChain’s mission is simple: enable faster, cheaper, and more stable transactions for the world’s most widely used stablecoin, USDT.

What Exactly Is StableChain?

StableChain is a Layer 1 blockchain network purpose-built for stablecoin payments and transfers. Rather than competing with all-purpose ecosystems, it focuses on one high-efficiency function—facilitating seamless USDT movement.

Think of it as the “bullet train” of digital finance—while Ethereum and TRON serve as open highways for all dApps, StableChain is a specialized, high-speed line exclusively for stablecoin transport. This specialization delivers major improvements in cost, throughput, and reliability.

Technical Framework: The Power Behind the Network

StableChain is powered by StableBFT, a newly developed consensus mechanism balancing high performance and robust security. It’s also EVM-compatible, allowing developers to migrate Ethereum-based applications effortlessly without rebuilding from scratch.

Transaction finality occurs within 100 - 350 milliseconds, and throughput reaches 3,000 - 10,000 TPS—a quantum leap beyond most existing blockchains.

USDT as Native Gas: A Simpler Model

One of StableChain’s most innovative features is the use of USDT as the native gas token.

Instead of holding ETH or TRX to pay fees, users can cover all costs directly in USDT.

• All transaction fees are paid in USDT
• Peer-to-peer transfers are free of charge
• Average transaction cost: less than $0.001

This design eliminates the friction of managing multiple tokens and shields users from fee volatility tied to other crypto assets.

Ultra-Fast, Low-Cost Transactions

StableChain is engineered for Web2-like responsiveness. Transactions confirm within milliseconds, and network congestion is virtually nonexistent.

At launch, the network achieves 3,000 TPS, with plans to scale past 10,000 TPS, making it ideal for global remittances, real-time settlements, and high-frequency payments.

Cross-Chain Integration and Enterprise Solutions

Beyond speed, StableChain emphasizes interoperability and enterprise adoption.

Through integration with LayerZero, USDT can move fluidly across multiple networks, increasing overall liquidity.

For institutional partners, StableChain introduces tailored features such as:

• Guaranteed block space for enterprises
• Batch transaction processing
• Confidential transaction options

Reports indicate that PayPal Ventures has invested in the project, signaling potential integration of PYUSD into the network and accelerating stablecoin adoption in the global payment ecosystem.

Liquidity Bootstrapping and Early Access Program

StableChain recently announced the second phase of its deposit program, set to launch on November 6 at 22:00 (UTC+8). With a total allocation of $500 million, the program is open exclusively to KYC-verified users, each limited to one wallet address.

Participants can deposit USDC, which will automatically convert to USDT on the Stable network—forming the foundation of early-stage liquidity and institutional engagement.

A Glimpse Into the Future of Stablecoin Networks

The creation of StableChain signifies the beginning of a self-sustaining stablecoin ecosystem—one that no longer depends on external Layer 1 chains.

For users, it means instant transactions, minimal fees, and maximum reliability. For Tether, it’s a strategic step toward consolidating the stablecoin economy under its own infrastructure.

As digital payments evolve, StableChain may well emerge as the core hub of global stablecoin activity, accelerating the mainstream adoption of blockchain-based finance.
