Stable, a new Layer 1 blockchain dedicated to USDT, seeks to drive stablecoin adoption by offering zero-fee USDT transfers and sub-second settlements.

Executive Summary

Stable, a new Layer 1 blockchain focused on USDT, is positioning itself as a "Trojan Horse" to drive mass adoption of stablecoins. By offering zero-fee USDT transfers and sub-second settlements, Stable aims to address the inefficiencies and high costs associated with existing stablecoin infrastructure. The network operates on a delegated Proof-of-Stake consensus mechanism called StableBFT, which delivers high throughput and sub-second block finality.

The Event in Detail

Stable is designed as a high-speed network specifically for USDT transactions. Key features include the elimination of gas fees, sub-second transaction confirmation, and a simplified user experience. All transaction fees are paid directly in USDT, removing the need for a separate gas token. The network operates on a "dual chain parallel" model, consisting of the Stable Public Chain (Layer 1) and the Plasma Chain. USDT on Stable exists in two variations: USDT0, a bridging token, and gasUSDT, a non-transferable asset for network fees. Both maintain a 1:1 peg to standard USDT.

Market Implications

Stable's strategy involves attracting users through free transfers, then expanding to payments, DeFi services, and institutional partnerships. By offering premium services like "Guaranteed Blockspace," Stable aims to ensure low costs and high reliability, particularly for corporate cross-border settlements. This could lead to increased adoption of USDT for payments and DeFi, potentially challenging existing payment systems like Visa and Paypal. The protocol aims to improve the utility and adoption of USDT, potentially increasing its market share and overall stablecoin usage.

Expert Commentary

According to a report by Tiger Research, Stable aims to drive mass adoption of stablecoins through zero gas fee P2P transfers and sub-second settlements. The report suggests that Stable can expand its ecosystem by developing institutional services and partnerships, providing premium services like "Guaranteed Blockspace" to ensure low costs and high reliability. The improved consensus mechanism can achieve confirmations in sub-second levels while maintaining extremely low costs.

Broader Context

Stable addresses the shortcomings of existing stablecoin infrastructure by offering a purpose-built environment for fast, affordable, and stable USDT transactions. The project raised $28 million in a seed funding round in July 2025, led by Bitfinex and Hack VC, with participation from Franklin Templeton, Castle Island Ventures, KuCoin Ventures, and Tether CEO Paolo Ardoino, highlighting the strategic relevance of the project.
