Sui TypeScript SDK

This is the Sui TypeScript SDK built on the Sui JSON RPC API. It provides utility classes and functions for applications to sign transactions and interact with the Sui network.

WARNING: Note that we are still iterating on the RPC and SDK API before TestNet, therefore please expect frequent breaking changes in the short-term. We expect the API to stabilize after the upcoming TestNet launch.

Working with DevNet

The SDK will be published to npm registry with the same bi-weekly release cycle as the DevNet validators and RPC Server. To use the SDK in your project, you can do:

$ npm install @mysten/sui.js

You can also use your preferred npm client, such as yarn or pnpm.

Working with local network

Note that the latest tag for the published SDK might go out of sync with the RPC server on the main branch until the next release. If you're developing against a local network, we recommend using the experimental-tagged packages, which contain the latest changes from main.

npm install @mysten/sui.js@experimental

Refer to the JSON RPC topic for instructions about how to start a local network and local RPC server.

Building Locally

To get started you need to install pnpm, then run the following command:

# Install all dependencies
$ pnpm install
# Run the build for the TypeScript SDK
$ pnpm sdk build

Type Doc

You can view the generated Type Doc for the current release of the SDK at http://typescript-sdk-docs.s3-website-us-east-1.amazonaws.com/.

For the latest docs for the main branch, run pnpm doc and open the doc/index.html in your browser.

Testing

To run unit tests

cd sdk/typescript
pnpm run test:unit

To run E2E tests against local network

cd sdk/typescript
pnpm run prepare:e2e
pnpm run test:e2e

To run E2E tests against DevNet

cd sdk/typescript
VITE_FAUCET_URL='https://faucet.devnet.sui.io:443/gas' VITE_FULLNODE_URL='https://fullnode.devnet.sui.io' pnpm test:e2e

Connecting to Sui Network

The JsonRpcProvider class provides a connection to the JSON-RPC Server and should be used for all read-only operations. The default URLs to connect with the RPC server are:

• local: http://127.0.0.1:9000
• DevNet: https://fullnode.devnet.sui.io

import { JsonRpcProvider, Network } from '@mysten/sui.js';
// connect to local RPC server
const provider = new JsonRpcProvider(Network.DEVNET);
// get tokens from the local faucet server
await provider.requestSuiFromFaucet(
  '0xbff6ccc8707aa517b4f1b95750a2a8c666012df3'
);

For local development, you can run cargo run --bin sui-test-validator to spin up a local network with a local validator, a fullnode, and a faucet server.

import { JsonRpcProvider, Network } from '@mysten/sui.js';
// connect to Devnet
const provider = new JsonRpcProvider(Network.LOCAL);
// get tokens from the DevNet faucet server
await provider.requestSuiFromFaucet(
  '0xbff6ccc8707aa517b4f1b95750a2a8c666012df3'
);

You can also pass in custom URLs to your own fullnode and faucet server

import { JsonRpcProvider } from '@mysten/sui.js';
// connect to a custom RPC server
const provider = new JsonRpcProvider('https://fullnode.devnet.sui.io', {
  // you can also skip providing this field if you don't plan to interact with the faucet
  faucetURL: 'https://faucet.devnet.sui.io',
});
// get tokens from a custom faucet server
await provider.requestSuiFromFaucet(
  '0xbff6ccc8707aa517b4f1b95750a2a8c666012df3'
);

Examples

Fetch objects owned by the address 0xbff6ccc8707aa517b4f1b95750a2a8c666012df3

import { JsonRpcProvider } from '@mysten/sui.js';
const provider = new JsonRpcProvider();
const objects = await provider.getOwnedObjectRefs(
  '0xbff6ccc8707aa517b4f1b95750a2a8c666012df3'
);

Fetch object details for the object with id 0xcff6ccc8707aa517b4f1b95750a2a8c666012df3

import { JsonRpcProvider } from '@mysten/sui.js';
const provider = new JsonRpcProvider();
const txn = await provider.getObject(
  '0xcff6ccc8707aa517b4f1b95750a2a8c666012df3'
);
// You can also fetch multiple objects in one batch request
const txns = await provider.getObjectBatch([
  '0xcff6ccc8707aa517b4f1b95750a2a8c666012df3',
  '0xdff6ccc8707aa517b4f1b95750a2a8c666012df3',
]);

Fetch transaction details from transaction digests:

import { JsonRpcProvider } from '@mysten/sui.js';
const provider = new JsonRpcProvider();
const txn = await provider.getTransactionWithEffects(
  '6mn5W1CczLwitHCO9OIUbqirNrQ0cuKdyxaNe16SAME='
);
// You can also fetch multiple transactions in one batch request
const txns = await provider.getTransactionWithEffectsBatch([
  '6mn5W1CczLwitHCO9OIUbqirNrQ0cuKdyxaNe16SAME=',
  '7mn5W1CczLwitHCO9OIUbqirNrQ0cuKdyxaNe16SAME=',
]);

Fetch transaction events from a transaction digest:

import { JsonRpcProvider } from '@mysten/sui.js';
const provider = new JsonRpcProvider();
const txEvents = await provider.getEventsByTransaction(
  '6mn5W1CczLwitHCO9OIUbqirNrQ0cuKdyxaNe16SAME='
);

Fetch events by sender address:

import { JsonRpcProvider } from '@mysten/sui.js';
const provider = new JsonRpcProvider();
const senderEvents = await provider.getEventsBySender(
  '0xbff6ccc8707aa517b4f1b95750a2a8c666012df3'
);

For any operations that involves signing or submitting transactions, you should use the Signer API. For example:

To transfer a 0x2::coin::Coin<SUI>:

import { Ed25519Keypair, JsonRpcProvider, RawSigner } from '@mysten/sui.js';
// Generate a new Ed25519 Keypair
const keypair = new Ed25519Keypair();
const provider = new JsonRpcProvider();
const signer = new RawSigner(keypair, provider);
const transferTxn = await signer.transferObjectWithRequestType({
  objectId: '0x5015b016ab570df14c87649eda918e09e5cc61e0',
  gasBudget: 1000,
  recipient: '0xd84058cb73bdeabe123b56632713dcd65e1a6c92',
});
console.log('transferTxn', transferTxn);

To split a 0x2::coin::Coin<SUI> into multiple coins

import { Ed25519Keypair, JsonRpcProvider, RawSigner } from '@mysten/sui.js';
// Generate a new Keypair
const keypair = new Ed25519Keypair();
const provider = new JsonRpcProvider();
const signer = new RawSigner(keypair, provider);
const splitTxn = await signer.splitCoinWithRequestType({
  coinObjectId: '0x5015b016ab570df14c87649eda918e09e5cc61e0',
  // Say if the original coin has a balance of 100,
  // This function will create three new coins of amount 10, 20, 30,
  // respectively, the original coin will retain the remaining balance(40).
  splitAmounts: [10, 20, 30],
  gasBudget: 1000,
});
console.log('SplitCoin txn', splitTxn);

To merge two coins:

import { Ed25519Keypair, JsonRpcProvider, RawSigner } from '@mysten/sui.js';
// Generate a new Keypair
const keypair = new Ed25519Keypair();
const provider = new JsonRpcProvider();
const signer = new RawSigner(keypair, provider);
const mergeTxn = await signer.mergeCoinWithRequestType({
  primaryCoin: '0x5015b016ab570df14c87649eda918e09e5cc61e0',
  coinToMerge: '0xcc460051569bfb888dedaf5182e76f473ee351af',
  gasBudget: 1000,
});
console.log('MergeCoin txn', mergeTxn);

To make a move call:

import { Ed25519Keypair, JsonRpcProvider, RawSigner } from '@mysten/sui.js';
// Generate a new Keypair
const keypair = new Ed25519Keypair();
const provider = new JsonRpcProvider();
const signer = new RawSigner(keypair, provider);
const moveCallTxn = await signer.executeMoveCallWithRequestType({
  packageObjectId: '0x2',
  module: 'devnet_nft',
  function: 'mint',
  typeArguments: [],
  arguments: [
    'Example NFT',
    'An NFT created by the wallet Command Line Tool',
    'ipfs://bafkreibngqhl3gaa7daob4i2vccziay2jjlp435cf66vhono7nrvww53ty',
  ],
  gasBudget: 10000,
});
console.log('moveCallTxn', moveCallTxn);

Subscribe to all events created by transactions sent by account 0xbff6ccc8707aa517b4f1b95750a2a8c666012df3

import { JsonRpcProvider } from '@mysten/sui.js';
const provider = new JsonRpcProvider();

// calls RPC method 'sui_subscribeEvent' with params:
// [ { SenderAddress: '0xbff6ccc8707aa517b4f1b95750a2a8c666012df3' } ]
const subscriptionId = await provider.subscribeEvent(
  { SenderAddress: '0xbff6ccc8707aa517b4f1b95750a2a8c666012df3' },
  (event: SuiEventEnvelope) => {
    // handle subscription notification message here. This function is called once per subscription message.
  }
);

// later, to unsubscribe
// calls RPC method 'sui_unsubscribeEvent' with params: [ subscriptionId ]
const subFoundAndRemoved = await provider.unsubscribeEvent(subscriptionId);

Subscribe to all events created by the devnet_nft module

import { JsonRpcProvider } from '@mysten/sui.js';
const provider = new JsonRpcProvider();

const devnetNftFilter = {
  All: [
    { EventType: 'MoveEvent' },
    { Package: '0x2' },
    { Module: 'devnet_nft' },
  ],
};
const devNftSub = await provider.subscribeEvent(
  devnetNftFilter,
  (event: SuiEventEnvelope) => {
    // handle subscription notification message here
  }
);

To publish a package:

import { Ed25519Keypair, JsonRpcProvider, RawSigner } from '@mysten/sui.js';
const { execSync } = require('child_process');
// Generate a new Keypair
const keypair = new Ed25519Keypair();
const provider = new JsonRpcProvider();
const signer = new RawSigner(keypair, provider);
const compiledModules = JSON.parse(
  execSync(
    `${cliPath} move build --dump-bytecode-as-base64 --path ${packagePath}`,
    { encoding: 'utf-8' }
  )
);
const modulesInBytes = compiledModules.map((m) =>
  Array.from(new Base64DataBuffer(m).getData())
);
const publishTxn = await signer.publishWithRequestType({
  compiledModules: modulesInBytes,
  gasBudget: 10000,
});
console.log('publishTxn', publishTxn);

Alternatively, a Secp256k1 can be initiated:

import { Secp256k1Keypair, JsonRpcProvider, RawSigner } from '@mysten/sui.js';
// Generate a new Secp256k1 Keypair
const keypair = new Secp256k1Keypair();

const provider = new JsonRpcProvider();
const signer = new RawSigner(keypair, provider);
