dispatch() (transaction)

Othent JS SDK dispatch() function

The dispatch() function allows you to quickly sign and send a transaction to the network in a bundled format. It is best for smaller datas and contract interactions. If the bundled transaction cannot be submitted, it will fall back to a base layer transaction. The function returns the result of the API call.

This function assumes (and requires) a user is authenticated. See requireAuth().

Tip: If you are trying to sign a larger piece of data (> 5 MB), make sure to notify the user to not switch / close the browser tab. Larger transactions are split into chunks in the background and will take longer to sign.

Tip: The function uses the default bundler node, or the one passed as an option. Consider using the signDataItem() function to create and sign a DataItem and manually send it to a custom bundler.

API

dispatch(
  transaction: Transaction,
  options?: DispatchOptions,
): Promise<ArDriveBundledTransactionData | UploadedTransactionData>;

`transaction: Transaction`

A valid Arweave Transaction instance, without a keyfile.

`options?: DispatchOptions`

options?.node?: UrlString (string)
Node used for bundling transactions. Defaults to ArDrive Turbo's node.
options?.arweave?: Arweave
Custom Arweave instance. Defaults to an instance connected to https://arweave.net:443.

`return Promise<ArDriveBundledTransactionData | UploadedTransactionData>`

A Promise containing the result of the upload request, including the ID of the submitted transaction, as as well as a type property indicating if it was uploaded by a bundle or directly to the base layer, as well as some additional properties:

interface ArDriveBundledTransactionData {
  type: "BUNDLED";
  id: string;
  timestamp: number;
  winc: string;
  version: string;
  deadlineHeight: number;
  dataCaches: string[];
  fastFinalityIndexes: string[];
  public: string;
  signature: string;
  owner: string;
}

interface UploadedTransactionData {
  type: "BASE";
  id: string;
  signature: string;
  owner: string;
}

Example usage

import Arweave from "arweave";
import { Othent } from "@othent/kms";

const arweave = new Arweave({
  host: "ar-io.net",
  port: 443,
  protocol: "https"
});

const othent = new Othent({ appInfo, throwErrors: false, ... });

// Make sure the user is authenticated, or prompt them to authenticate:
await othent.requireAuth();

// Create a transaction:
const transaction = await arweave.createTransaction({
  data: '<html><head><meta charset="UTF-8"><title>Hello permanent world! This was signed via ArConnect!!!</title></head><body></body></html>'
});

// Dispatch (and sign) it using the default bundler:
const dispatchResult = await othent.dispatch(transaction);

console.log(`The transaction was dispatched as a ${ dispatchResult.type === "BUNDLED" ? "bundled" : "base layer" } Arweave transaction.`);
