# Kaia Blockchain

> Why Ratio is built on Kaia and what it means for partners

Ratio is built on the [Kaia blockchain](https://kaia.io) — 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

<CardGroup cols={2}>
  <Card title="Sub-second finality" icon="bolt">
    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.
  </Card>

  <Card title="EVM compatible" icon="code">
    Fully EVM-compatible — Ratio's contracts are Solidity, developed and audited with standard Ethereum tooling (Hardhat, Foundry, OpenZeppelin).
  </Card>

  <Card title="Asia-focused ecosystem" icon="earth-asia">
    Distribution partners (LINE, Kakao, GCash) with hundreds of millions of users, local stablecoin issuers (IDRX, MYRC, tnSGD), and DeFi protocols (SuperEarn, AlphaSec).
  </Card>

  <Card title="Low transaction costs" icon="money-bill">
    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.
  </Card>
</CardGroup>

## 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.

<Tip>
  As new stablecoins launch on Kaia, Ratio can add corresponding corridors through configuration — no protocol changes required.
