kaia

const kaia: object

Kaia mainnet — priority 2 production chain.

Kaia (Klaytn + Finschia) runs IBFT consensus with immediate finality — a single confirmed block is final — so defaultConfirmations is 1 (do NOT copy Polygon’s 4). JPYC is live at the same address as the other chains (src/tokens/jpyc.ts).

Note: ZeroDev does not support Kaia, so the smart-account path (session keys, sponsored UserOps) is not yet available here — it is planned via Pimlico (M5-3 Phase 2). The x402 EOA-payer path works today.
