Asia’s Cross-Border Money Is Moving Onchain

Ratio is a B2B middleware for stablecoin FX and settlement built atop Kaia's onchain settlement rail, targeting Asian corridors (initially USD–IDR and USD–JPY) to reduce cost and settlement time; a Kaia PoC reported sub-3-second settlement and ~87% lower cross-border transaction costs versus Ethereum. The report outlines Ratio's hybrid onchain/offchain architecture (onchain settlement and pool accounting, offchain quoting and risk controls), single-sided pools, oracle pricing, distribution advantages in Asia, regulatory progress, and the importance of end-to-end verification and audits (CertiK) before scaling to institutional volumes.
