types.PolkadotConfig

Properties

metadata

Optional metadata: Record<string, `0x${string}`>

provide a locally saved metadata file for a modestly fast startup time (e.g. 1 second when provided, 1.5 seconds without).

Note

if not provided the SDK will read the needed data from chain during startup

Note

format is key as genesis hash and spec version and the value hex encoded chain metadata

Example

creating valid metadata

const meta = _polkadotApi.runtimeMetadata.toHex();
const genesisHash = _polkadotApi.genesisHash;
const specVersion = _polkadotApi.runtimeVersion.specVersion;

const metadata = {
[`${genesisHash}-${specVersion}`]: meta,
};
