Stable Raises $28M to Build USDT-Optimized Blockchain for Global Payments

Stable, a blockchain platform focused on Tether’s (USDT) utility, has raised $28 million in seed funding led by Bitfinex and Hack VC, with contributions from Franklin Templeton, Castle Island Ventures, KuCoin Ventures, and angel investors such as Tether CEO Paolo Ardoino and Braintree co-founder Bryan Johnson [1]. The funding is intended to develop what the company calls a “stablechain,” designed to optimize USDT for global digital payments, leveraging low fees, fast transaction speeds, and a stable unit of account [2].

According to Stable’s CEO, Joshua Harding, the current global payment infrastructure has failed to meet the needs of a rapidly digitizing economy. The new platform aims to address these shortcomings by building on the trust and liquidity of stablecoins to deliver instant and secure cross-border transactions [3]. Harding also emphasized the importance of collaboration with major investors from both traditional and crypto finance, which reflects shared confidence in the future of digital payments [4].

The company has outlined a three-phase development plan for the remainder of the year. The first phase includes integrating USDT as the gas token with sub-second block times. The second phase will focus on enterprise-grade payment solutions, while the third will prioritize developer tools and ecosystem expansion [5]. The roadmap underscores a strategic shift toward building scalable infrastructure that can support broader adoption of stablecoin-based transactions.

The funding coincides with a broader surge in interest in stablecoin-backed blockchains, particularly as the stablecoin market has grown to $273 billion, dominated by USDT and USDC. This momentum is further supported by regulatory developments like the recent U.S. GENIUS Act, which seeks to establish clearer guidelines for stablecoin operations [6].

Stable is part of a growing wave of projects focused on enhancing stablecoin utility. For instance, another stablecoin network, Plasma, recently raised $373 million in a token sale offering free stablecoin transfers, highlighting a competitive yet complementary innovation trend [7]. These efforts suggest a broader industry push toward leveraging stablecoin liquidity for more efficient and accessible financial systems.

The round was announced through multiple channels, including X posts from Stable and Hack VC, and was widely covered by financial and blockchain media within a four-day window [8]. The participation of traditional and venture capital investors signals increasing institutional confidence in the potential of stablecoin-centric blockchains to redefine digital finance [9].
