Interface: PolkadotConfig
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,
};
