Welcome to Ratio
Asia's purpose-built stablecoin orchestration layer for institutional cross-border payments.
Ratio is a B2B middleware infrastructure that orchestrates stablecoins across banks, e-wallets, and payment service providers through a single API integration — built on the Kaia blockchain with sub-second settlement finality.
With one integration, the Stablecoin Orchestration Layer (SOL) abstracts the immense technical and regulatory complexity of local Asian markets, providing an end-to-end solution for intelligent liquidity routing, optimised FX swaps, and instant cross-border settlement.
