From Chain Metadata

Send a batch of dispatch calls and atomically execute them. The whole transaction will rollback and fail if any of the calls failed. May be called from any origin except `None`. `calls`: The calls to be dispatched from the same origin. The number of call must not exceed the constant: `batched_calls_limit` (available in constant metadata). If origin is root then the calls are dispatched without checking origin filter. (This includes bypassing `frame_system::Config::BaseCallFilter`). ## Complexity O(C) where C is the number of calls to be batched.

Code Examples

import { createClient, Binary } from "polkadot-api";
import { getWsProvider } from "polkadot-api/ws";
import { sub } from "@polkadot-api/descriptors"; // generated by: npx papi add sub -w wss://entrypoint-finney.opentensor.ai:443

const client = createClient(getWsProvider("wss://entrypoint-finney.opentensor.ai:443"));
const api = client.getTypedApi(sub);

// Build batch_all call (typed, named args)
const calls = [] as [];

const tx = api.tx.Utility.batch_all({
  calls,
});
