Typescript SDK for Endless

Reference Docs

1. For SDK documentation, check out the TypeScript SDK documentation
2. For in-depth examples, check out the examples folder with ready-made package.json files to get you going quickly!

The Endless TypeScript SDK provides a convenient way to interact with the Endless blockchain using TypeScript. It offers a set of utility functions, classes, and types to simplify the integration process and enhance developer productivity.

This repository supports version >= 0.0.0 of the Endless SDK npm package.

Installation

For use in Node.js or a web application

Install with your favorite package manager such as npm, yarn, or pnpm:

pnpm install endless-ts-sdk

Usage

Initialize Endless to access the SDK API.

// initiate the main entry point into Endless SDK
const endless = new Endless();

If you want to pass in a custom config

// an optional config information for the SDK client instance.
const config = new EndlessConfig({
  network: Network.LOCAL,
  // If it is a mini program environment, set miniprogram to true
  // miniprogram: true
}); // default network is devnet
const endless = new Endless(config);

Account management (default to Ed25519)

Note: We introduce a Single Sender authentication. Generating an account defaults to Legacy Ed25519 authentication with the option to use the Single Sender unified authentication

Generate new keys

const account = Account.generate(); // defaults to Legacy Ed25519

Derive from private key

// Create a private key instance for Ed25519 scheme
const privateKey = new Ed25519PrivateKey("myEd25519privatekeystring");

// Derive an account from private key

// This is used as a local calculation and therefore is used to instantiate an `Account`
// that has not had its authentication key rotated
const account = await Account.fromPrivateKey({ privateKey });

Derive from private key and address

// Create a private key instance for Ed25519 scheme
const privateKey = new Ed25519PrivateKey("myEd25519privatekeystring");

Derive from path

const path = "m/44'/637'/0'/0'/1";
const mnemonic = "various float stumble...";
const account = Account.fromDerivationPath({ path, mnemonic });

Submit transaction

Single Signer transaction

Using transaction submission api

const alice: Account = Account.generate();
const bobAddress = "0xb0b";
// build transaction
const transaction = await endless.transaction.build.simple({
  sender: alice.accountAddress,
  data: {
    function: "0x1::coin::transfer",
    typeArguments: ["0x1::endless_coin::EndlessCoin"],
    functionArguments: [bobAddress, 100],
  },
});

// using sign and submit separately
const senderAuthenticator = endless.transaction.sign({ signer: alice, transaction });
const committedTransaction = await endless.transaction.submit.simple({ transaction, senderAuthenticator });

// using signAndSubmit combined
const committedTransaction = await endless.signAndSubmitTransaction({ signer: alice, transaction });

Using built in transferCoinTransaction

const alice: Account = Account.generate();
const bobAddress = "0xb0b";
// build transaction
const transaction = await endless.transferCoinTransaction({
  sender: alice,
  recipient: bobAddress,
  amount: 100,
});

const pendingTransaction = await endless.signAndSubmitTransaction({ signer: alice, transaction });

Troubleshooting

If you see import error when you do this

import { Endless, EndlessConfig, Network } from "endless-ts-sdk";

It could be your tsconfig.json is not incompatible, make sure your moduleResolution is set to node instead of bundler.
