Stable raises $28M to build USDT-optimized blockchain with sub-second block times

Stable, a Layer 1 blockchain platform focused on enhancing the utility of Tether’s USDT, has secured $28 million in seed funding, led by Bitfinex and Hack VC, with participation from Franklin Templeton, Castle Island Ventures, KuCoin Ventures, and angel investors including Tether CEO Paolo Ardoino and Braintree co-founder Bryan Johnson [1]. The funding will support the development of a blockchain optimized for USDT transactions, aiming to provide faster, more secure, and cost-effective digital payments [2].

The platform, known as "Stablechain," is designed to serve as a dedicated infrastructure for stablecoin transactions, particularly leveraging USDT’s liquidity. CEO Joshua Harding emphasized that current global payment systems are outdated and unable to meet the demands of a rapidly digitizing economy [3]. Stable’s solution aims to integrate USDT into its core protocol, offering sub-second block times and enterprise-grade infrastructure to streamline cross-border transactions [4]. The project’s roadmap outlines three phases for the remainder of the year: the first focuses on using USDT as the gas token with optimized block times, the second on enterprise payment solutions, and the third on expanding tools for developers and ecosystem growth [5].

The fundraising aligns with the broader trend of stablecoin-optimized blockchains, particularly as U.S. regulatory clarity improves. The recently passed GENIUS Act provides a clearer regulatory framework for stablecoin operations, encouraging innovation in digital payments [6]. This regulatory shift has bolstered confidence in the sector, as evidenced by the participation of both institutional and crypto-native investors in Stable’s funding round [9].

The announcement was widely covered in crypto and financial media within four days of its release, with coordinated updates shared via public platforms like X [8]. Tether CEO Paolo Ardoino, who also serves as CTO of Bitfinex, praised Stable’s infrastructure and roadmap, noting that the project is well-positioned to expand USDT’s adoption in light of evolving U.S. policies [7].

Stable’s initiative reflects a growing industry movement to modernize global financial systems through stablecoin-based solutions. By focusing on USDT’s scalability and reliability, the platform aims to bridge the gap between traditional and digital finance, offering instant, secure, and scalable cross-border transaction capabilities.
