Class ContractDryRun<E>

invokeMethod

• invokeMethod<T>(entrypoint: EntrypointName.Type<E>, metaOrInvoker: AccountAddress | ContractAddress | ContractInvokeMetadata, serializer: ((input: T) => ArrayBuffer), input: T, blockHash?: BlockHash): Promise<InvokeContractResult>

• Performs a dry-run of a contract entrypoint invocation. Useful for getting an indication of the result of an invocation of the entrypoint (e.g. getting a cost estimate).

  Returns

  the contract invocation result, which includes whether or not the invocation succeeded along with the energy spent.
