Kii is integrating its on-chain foreign exchange (FX) infrastructure into the Stable ecosystem, a move designed to enhance cross-border payment efficiency. The integration provides Stable's users, fintech clients, and enterprise partners with 24/7 FX execution and automated routing, aiming to create smoother settlement for stablecoin payment flows.

This partnership addresses a critical bottleneck in the digital asset space: the mismatch between the 24/7 nature of cryptocurrencies and the traditional Monday-Friday world of FX markets. Traditional FX settlement can take hours or even days, creating friction and risk for cross-border payments. By serving as a dedicated on-chain FX layer, Kii aims to provide more competitive and responsive pricing directly on-chain.

KiiChain, described as an EVM-compatible Layer 1 AppChain, is built specifically for this purpose. The integration signals a broader industry trend of developing specialized infrastructure to bridge the gap between blockchain-based finance and legacy financial systems. It follows similar moves by other major players, highlighting a growing focus on building robust rails for global stablecoin utility.
