Stable Shakes Up Crypto: Launches First-Ever USDT-Optimized Layer 1 Blockchain

Move over, legacy payment rails—Stable just dropped a blockchain that eats USDT transfers for breakfast.

The Game-Changer

No more gas wars or network congestion. Stable's new Layer 1 is purpose-built to handle Tether transactions at scale, cutting settlement times to sub-second speeds while keeping fees lower than a Wall Street banker's moral standards.

Why It Matters

This isn't just another 'Ethereum killer.' By architecting the chain from the ground up for stablecoin payments, Stable bypasses the patchwork solutions currently bolted onto existing networks. Merchants get instant finality; traders escape the volatility trap.

The Bottom Line

Watch for exchanges to integrate this faster than you can say 'regulatory arbitrage.' In a world where 75% of crypto trades involve USDT, optimizing the plumbing could finally make crypto payments viable—assuming the SEC doesn't ruin the party first.

TLDR

• Stable Launches USDT-Only Blockchain for Instant, Low-Fee Payments
• Gas-Free USDT Transfers Arrive with Stable’s High-Speed Stablechain
• Stablechain Uses USDT as Native Gas, Ends Volatile Fee Woes
• Backed by Bitfinex, Stable Powers Global Payments with LayerZero-Linked USDT0
• Stable Brings EVM Dev Tools and Web2 UX to Stablecoin Settlements

Stable has introduced a new LAYER 1 blockchain tailored for USDT payments, aiming to solve issues tied to stablecoin usage. The chain, branded as a “stablechain,” integrates Tether’s USDT as its native token for gas and settlement. It is built to offer sub-second finality, ultra-low fees and enterprise-grade scalability for seamless global payments.

Stablechain Launches with USDT at Core

Stable positions itself as the first blockchain built for stablecoins, with USDT powering all transactions and gas fees. Unlike general-purpose chains, Stable eliminates the need for volatile tokens by letting users pay fees in USDT directly. The chain also supports gas-free peer-to-peer USDT transfers through a LayerZero-powered token called USDT0.

This approach simplifies how users and businesses interact with digital dollars, especially for cross-border transactions and retail payments. With a transaction confirmation time under one second and fees under a cent, Stable promises predictable, high-speed payment performance. The chain also targets both everyday use and institutional-grade functionality.

Stable allows developers to deploy dApps with familiar tools and enables new capabilities specific to stablecoin applications. The infrastructure includes an SDK suite, APIs and specialized support for stablecoin-based payment systems, lending platforms, and DeFi tools. Stable also integrates features like human-readable wallet aliases and fiat on-ramps through the Stable Wallet.

Enterprise Features Enhance Utility and Adoption

Stable has introduced multiple features tailored for high-volume businesses and institutions requiring predictable blockchain performance. These include guaranteed blockspace, batch settlement processing and private transfer mechanisms for regulatory-compliant confidentiality. The infrastructure is designed to handle thousands of transactions per second without congestion.

The platform’s future upgrades aim to strengthen its role in the stablecoin ecosystem. Phase 2 will adopt optimistic parallel execution to boost throughput and integrate enterprise-centric blockspace allocation. Phase 3 will upgrade the network to a DAG-based consensus system, further improving speed, resilience, and resource efficiency.

USDT’s dominance in global transaction volume gives Stable a significant advantage in targeting real-world financial use cases. Businesses relying on digital dollars can now bypass legacy processors and deploy cost-effective systems directly on-chain. Stablechain is thus positioning itself as a direct infrastructure layer for global commerce and digital finance.

Backing, Integration and Regulatory Timing

Bitfinex and the team behind the decentralized USDT0 token, designed for zero-gas stablecoin transfers, support the project. USDT0 enables seamless bridging across multiple blockchain networks using LayerZero’s messaging protocol, enhancing Stable’s interoperability with the broader ecosystem. While the development team remains undisclosed, Tether’s CEO previously acknowledged the project as having emerged from stealth mode.

Stable’s release coincides with growing regulatory momentum in the United States. The introduction of the GENIUS Act marks progress in setting standards for stablecoin governance and issuance. This timing could help legitimize purpose-built chains like Stable that align with regulatory frameworks while scaling real-world applications.

Bitfinex had previously invested $3.5 million in Plasma, a separate project building a sidechain optimized for USDT usage. However, Stable goes further by creating a fully dedicated Layer 1 architecture for stablecoins. This reflects a strategic shift toward blockchain systems designed exclusively for fiat-backed tokens
