getRuntimeVersion

  • getRuntimeVersion(): Promise<SubstrateRuntimeVersion>

  • Get current version of the runtime This is similar to .runtimeVersion but also ensure the corresponding metadata of this runtime version is downloaded & setup.

    This is helpful when you want to check runtime version to prepare for runtime upgrade

    Returns Promise<SubstrateRuntimeVersion>

off

  • off(event, handler?): this

  • Parameters

    • event: Events
    • Optionalhandler: HandlerFn

    Returns this

on

  • on(event, handler): Unsub

  • Parameters

    • event: Events
    • handler: HandlerFn

    Returns Unsub

once

  • once(event, handler): Unsub

  • Parameters

    • event: Events
    • handler: HandlerFn

    Returns Unsub

setSigner

  • setSigner(signer?): void

  • Update the signer instance for signing transactions

    Parameters

    • Optionalsigner: Signer

    Returns void
