The Stable blockchain, a Tether-supported LAYER 1 network, is set to transition its native gas token from gUSDT to USDT0 on February 4, 2026, as part of a protocol upgrade aimed at streamlining user experience and enhancing production readiness for its stablecoin-focused ecosystem. This v1.2.0 update arrives just two months after the blockchain’s launch, signaling rapid development. The move eliminates token conversion hassles, unifies fee payments, and strengthens institutional adoption. With over $780M in on-chain value and partnerships with heavyweights like Anchorage Digital and PayPal Ventures, Stable is positioning itself as a leader in enterprise-grade stablecoin infrastructure.

What is the Stable Platform?

Stable is a Layer 1 blockchain specifically designed for stablecoin transactions, backed by Tether—the issuer of USDT, the world’s largest stablecoin. Launched on December 8, 2025, the network has already processed over $780 million in on-chain value and secured partnerships with institutional players like Anchorage Digital, PayPal Ventures, and Orbital. The platform’s thesis revolves around creating a native stablecoin infrastructure for real-world payments, addressing gaps in existing blockchain systems.

Stable’s architecture prioritizes enterprise adoption through low-cost features for high-volume users, sub-second block finality via its StableBFT consensus mechanism, and full EVM compatibility. Unlike traditional blockchains where gas fees are paid in volatile native tokens (like ETH), Stable processes all transactions in USDT, eliminating treasury headaches for payment processors and financial institutions.

Why the Switch from gUSDT to USDT0?

The February 4 upgrade replaces gUSDT with USDT0 as the native gas asset, simplifying user experience by removing the need for token conversions. This unification allows fee payments and settlements to occur in a single stablecoin-denominated flow. In practical terms, this means users no longer need to juggle multiple token types for transactions—a pain point especially for institutional users managing large-scale operations.

Paolo Ardoino, CEO of Tether, emphasized in a recent interview: "This upgrade reflects our commitment to creating frictionless financial infrastructure. By eliminating conversion steps, we’re reducing operational complexity for businesses building on Stable."

Key Improvements in the v1.2.0 Upgrade

Beyond the gas token transition, the update introduces several technical enhancements:

• On-chain staking completion signals: A protocol-level feature that lets applications deterministically track staking lifecycle completion without polling.
• Solidity compatibility fixes: Resolves issues for developers building smart contracts.
• API-managed gas exemptions: Enables zero-gas-cost transactions for specific controlled flows.

Partners are advised to update systems to support USDT0-based gas fees across all transaction processes. The upgrade also requires indexers to detect the new unbonding completion signal—a change that improves transparency for staking operations.

Competitive Landscape and Future Roadmap

Stable isn’t alone in the race for enterprise stablecoin dominance. Competitors like Circle’s Arc and Stripe’s Tempo announced similar networks in 2025, while Bitfinex-backed Plasma launched its mainnet beta in September 2025. However, Stable’s early traction—with $28M in initial funding led by Bitfinex and Hack VC—gives it a head start.

The platform plans to launch StablePay, its consumer-facing digital wallet, later this year, featuring free P2P transfers. Through continued corporate collaborations, Stable aims to become the go-to platform for institutional payment flows. As one BTCC analyst noted: "Stable’s focus on eliminating crypto volatility from enterprise operations could make it the dark horse of 2026’s blockchain adoption race."
