Type Alias ChainClient<TChains>

ChainClient: { [K in string & keyof TChains]: TypedApi<TChains[K]> } & {
destroy: () => void;
raw: { [K in string & keyof TChains]: PolkadotClient };
}

A connected chain client returned by createChainClient or getChainAPI.

Each key from your config maps to a fully-typed PAPI TypedApi. Access raw PolkadotClient instances via .raw for advanced use cases like creating an InkSdk for contract interactions.

Type Parameters

TChains extends Record<string, ChainDefinition>
The chain descriptor record used to create this client.

Type Declaration

destroy: () => void
Destroy all connections managed by this client.
raw: { [K in string & keyof TChains]: PolkadotClient }
Raw PolkadotClient instances, keyed by chain name. Use for advanced APIs like createInkSdk.

Example

// Typed API access — fully typed from your descriptors
const account = await client.assetHub.query.System.Account.getValue(addr);

// Raw client for advanced use (e.g., InkSdk for contracts)
import { createInkSdk } from "@polkadot-api/sdk-ink";
const inkSdk = createInkSdk(client.raw.assetHub, { atBest: true });
