What Is Stable? The USDT-Optimized Blockchain for Scalable Stablecoin Transactions

Stable is a high-performance Layer-1 blockchain dedicated to USDT, the world’s leading stablecoin with over $150 billion in circulation and 350 million users. Designed to address infrastructure bottlenecks in payments, DeFi, and cross-border transfers, Stable delivers gas-free USDT0 transactions, sub-second finality, and enterprise-grade features, making it the ideal settlement layer for stablecoin activity in 2025’s $300 billion+ market.

Core Architecture: dPoS and EVM Compatibility

Stable operates on a delegated Proof-of-Stake (dPoS) consensus, achieving sub-second block times and single-slot finality for instant, reliable settlements. Fully EVM-compatible, it supports Ethereum tooling and smart contracts, enabling seamless migration of dApps. USDT serves as the gas token for non-USDT0 transfers, with automatic conversions via bundler and paymaster systems.

• Consensus: dPoS for efficiency and security.
• Compatibility: 100% EVM; low migration barriers.
• Gas Model: USDT0 for fees; gas-free for USDT0 transfers via EIP-7702 and Account Abstraction.

Key Features: Optimized for USDT

Stable prioritizes USDT usability with tailored innovations:

• Gas-Free USDT0 Transfers: EIP-7702 enables zero-fee USDT0 sends, simplifying retail and institutional flows.
• Sub-Second Finality: Under 1-second confirmations for high-frequency payments.
• USDT0 Cross-Chain Bridge: Seamless bridging from Ethereum, Arbitrum, HyperEVM, Tron, and more.
• Stable Wallet: Web2.5 UX for intuitive sending, receiving, and card integrations.
• Enterprise Tools: Guaranteed blockspace, transfer aggregation for throughput, confidential transfers balancing privacy and compliance.

Future enhancements include USDT Transfer Aggregator for bundled efficiency and Guaranteed Blockspace for predictable institutional use.

Use Cases: From Retail to Institutions

Stable excels in:

• Retail Payments: Everyday users send USDT0 gas-free via mobile wallets.
• DeFi Integration: High-throughput lending, borrowing, and RWAs with minimal costs.
• Institutional Flows: Large-scale settlements with compliance and privacy.

In DeFi’s $150 billion+ TVL era, Stable reduces costs by 90% for remittances and unlocks $10 trillion in tokenized assets.

2025 Outlook: $300B Stablecoin Catalyst

Stable could capture 10% of USDT volume, driving $30 billion in transactions. Risks include regulatory shifts, but dPoS and EVM compatibility mitigate scalability concerns.

In summary, Stable’s USDT-focused blockchain revolutionizes stablecoin efficiency, blending speed, security, and usability for DeFi’s future.
