KawaseChain

A viem Chain extended with kawasekit-specific routing + finality metadata.

All standard chain fields (id, rpcUrls, blockExplorers, nativeCurrency, …) are inherited from viem’s Chain. kawasekit adds only the fields below; per-token deployment info lives in src/tokens/.

defaultConfirmations / blockTimeMs are config-as-data: the facilitator reads them instead of branching on chain identity, so finality depth is a per-chain property rather than a code path (cf. the finality-tuning recipe at docs/recipes/facilitator-finality-tuning.md).

Example

import { polygon } from "kawasekit";

console.log(polygon.id);                   // 137
console.log(polygon.isTestnet);            // false
console.log(polygon.defaultConfirmations); // 4

Properties

blockExplorers?

optional blockExplorers?: object

Defined in: node_modules/.pnpm/viem@2.50.4_typescript@6.0.3_zod@4.4.3/node_modules/viem/_types/types/chain.d.ts:15

Collection of block explorers

Index Signature

[key: string]: ChainBlockExplorer

default

default: ChainBlockExplorer

Inherited from

Chain.blockExplorers

blockTime?

optional blockTime?: number

Defined in: node_modules/.pnpm/viem@2.50.4_typescript@6.0.3_zod@4.4.3/node_modules/viem/_types/types/chain.d.ts:20

Block time in milliseconds.

Inherited from

Chain.blockTime

blockTimeMs

readonly blockTimeMs: number

Defined in: src/chains/types.ts:41

Approximate block time in milliseconds. Used to auto-size the settle receiptTimeoutMs default from the confirmation depth, and as the basis for the finality-tuning recipe’s wall-time estimates.

contracts?

optional contracts?: object

Defined in: node_modules/.pnpm/viem@2.50.4_typescript@6.0.3_zod@4.4.3/node_modules/viem/_types/types/chain.d.ts:22

Collection of contracts

custom?

optional custom?: Record<string, unknown>

Inherited from

Chain.custom

defaultConfirmations

readonly defaultConfirmations: number

Defined in: src/chains/types.ts:35

Default settle confirmation depth for this chain (threat 2.8 / §6.6). Set by the chain’s finality model, not copied across chains: probabilistic chains (Polygon) need depth; deterministic-finality chains (Avalanche Snowman, Kaia IBFT) need 1-2; Ethereum needs ~32. Operators override via CreateSelfFacilitatorParams.confirmations.

ensTlds?
