July 31, 2025 – TCI – KuCoin Ventures, the investment arm of global cryptocurrency exchange KuCoin, has announced a strategic investment in Stable, a high-throughput Layer 1 blockchain explicitly designed for stablecoin issuance, settlement, and payments infrastructure. Powered by USDT, Stable positions itself as the first “Stablechain”, a blockchain purpose-built to support stablecoin activity at scale.
The project is supported by teams from both Tether and Bitfinex, with Bitfinex CTO Paolo Ardoino advising the initiative. The investment round included participation from KuCoin Ventures, Ardoino, Bitfinex, Hack VC, and Franklin Templeton, among others. The presence of both crypto-native and traditional finance investors reflects a growing consensus around the need for improved stablecoin infrastructure.
Unlike general-purpose blockchains such as Ethereum or Tron, Stable is optimized for stablecoin use cases and aims to solve several limitations seen in today’s on-chain payments. These include unpredictable fees, delayed confirmation times, and friction in user experience. Stable’s design introduces a more streamlined approach to payments by incorporating features directly into its core protocol.
“Payments infrastructure around the world needs an overhaul, and traditional methods have failed to achieve fast, reliable, and secure digital payments despite massive demand from consumers across the globe,” said Joshua Harding, Co-founder and CEO of Stable. “Stable was developed to take advantage of the potential behind stablecoins like USDT to offer instant and seamless payments, directly addressing problems with current payment rails. The support we have received from major investors in both crypto and traditional finance shows that they share our vision, one that we are incredibly excited to work alongside them to make a reality.”
One of Stable’s key differentiators is its use of USDT as the native gas token, eliminating the need for users to hold a separate platform token. Peer-to-peer USDT transfers are gas-free, which significantly simplifies the payment process. The blockchain is built on the StableBFT consensus, derived from Cosmos’ CometBFT, and is set to integrate DAG (Directed Acyclic Graph) architecture to further increase throughput and reduce confirmation times. Additionally, Stable supports enterprise-grade scalability, allowing businesses to apply for dedicated block space to ensure predictable transaction performance.
Commenting on the investment, Cass Tsai, Head of KuCoin Ventures, said:
“We firmly believe in the long-term potential of stablecoins in global payment ecosystems. Stable, as a high-performance blockchain tailored for USDT, provides a clear path forward for scalable stablecoin circulation, settlement, and cross-border use cases. We look forward to working with the Stable team to advance the development of a global stablecoin clearing and settlement network, and to support the industry’s next growth chapter.”
The investment marks a continuation of KuCoin Ventures’ strategic focus on next-generation payment infrastructure and stablecoin ecosystems, recognizing the role stablecoins will play in future financial systems.
