Ratio is built on the Kaia blockchain — a high-performance Layer 1 designed for mass adoption in Asia. Kaia provides the settlement infrastructure that makes instant, atomic FX execution possible.

​
Why Kaia

Sub-second finality

Kaia’s BFT consensus provides deterministic, immediate finality. Once confirmed, a transaction is final — no reorgs, no probabilistic confirmation. Essential for institutional FX where settlement certainty is non-negotiable.

EVM compatible

Fully EVM-compatible — Ratio’s contracts are Solidity, developed and audited with standard Ethereum tooling (Hardhat, Foundry, OpenZeppelin).

Asia-focused ecosystem

Distribution partners (LINE, Kakao, GCash) with hundreds of millions of users, local stablecoin issuers (IDRX, MYRC, tnSGD), and DeFi protocols (SuperEarn, AlphaSec).

Low transaction costs

Gas fees are a fraction of Ethereum mainnet, making it viable to settle every individual swap on-chain — even micro-transactions. No batch settlement needed.

​
What Kaia means for partners

Partners don’t interact with the blockchain directly. Ratio’s API abstracts all on-chain operations — partners send API requests and receive settlement confirmations without managing wallets, signing transactions, or paying gas. However, partners benefit indirectly:
  • Settlement certainty — Every confirmed swap is backed by a finalised on-chain transaction with no risk of reversal.
  • Auditability — Every settlement has a tx_hash verifiable on Kaia’s block explorer — an independent audit trail for compliance.
  • Transparency — Pool balances, LP token supply, and fee distributions are all visible on-chain.

Stablecoin ecosystem on Kaia

Kaia is actively onboarding stablecoins across Asian currencies:
As new stablecoins launch on Kaia, Ratio can add corresponding corridors through configuration — no protocol changes required.
