A TypeScript library for creating Monero applications using RPC and WebAssembly bindings to monero v0.18.4.0 'Fluorine Fermi'.

This fork tries to be as backwards compatible with older versions as possible.

• Supports client-side wallets in Node.js and the browser using WebAssembly.
• Supports wallet and daemon RPC clients.
• Supports multisig, view-only, and offline wallets.
• Wallet types are interchangeable by conforming to a common interface.
• Uses a clearly defined data model and API specification intended to be intuitive and robust.
• Query wallet transactions, transfers, and outputs by their properties.
• Fetch and process binary data from the daemon (e.g. raw blocks).
• Receive notifications when blocks are added to the chain or when wallets sync, send, or receive.
• Over 300 passing Mocha tests.

Build browser or Node.js applications using RPC or WebAssembly bindings to monero-project/monero. Wallet implementations are interchangeable by conforming to a common interface, MoneroWallet.ts.

// import monero-ts (or import types individually)
import moneroTs from "monero-ts";

// connect to daemon
let daemon = await moneroTs.connectToDaemonRpc("http://localhost:28081");
let height = await daemon.getHeight();        // 1523651
let txsInPool = await daemon.getTxPool();     // get transactions in the pool

// create wallet from mnemonic phrase using WebAssembly bindings to monero-project
let walletFull = await moneroTs.createWalletFull({
  path: "sample_wallet_full",
  password: "supersecretpassword123",
  networkType: moneroTs.MoneroNetworkType.TESTNET,
  seed: "hefty value scenic...",
  restoreHeight: 573936,
  server: { // provide url or MoneroRpcConnection
    uri: "http://localhost:28081",
    username: "superuser",
    password: "abctesting123"
  }
});

// synchronize with progress notifications
await walletFull.sync(new class extends moneroTs.MoneroWalletListener {
  async onSyncProgress(height: number, startHeight: number, endHeight: number, percentDone: number, message: string) {
    // feed a progress bar?
  }
});

// synchronize in the background every 5 seconds
await walletFull.startSyncing(5000);

// receive notifications when funds are received, confirmed, and unlocked
let fundsReceived = false;
await walletFull.addListener(new class extends moneroTs.MoneroWalletListener {
  async onOutputReceived(output: moneroTs.MoneroOutputWallet) {
    let amount = output.getAmount();
    let txHash = output.getTx().getHash();
    let isConfirmed = output.getTx().getIsConfirmed();
    let isLocked = output.getTx().getIsLocked();
    fundsReceived = true;
  }
});

// connect to wallet RPC and open wallet
let walletRpc = await moneroTs.connectToWalletRpc("http://localhost:28084", "rpc_user", "abc123");
await walletRpc.openWallet("sample_wallet_rpc", "supersecretpassword123");
let primaryAddress = await walletRpc.getPrimaryAddress(); // 555zgduFhmKd2o8rPUz...
let balance = await walletRpc.getBalance();   // 533648366742
let txs = await walletRpc.getTxs();           // get transactions containing transfers to/from the wallet

// send funds from RPC wallet to WebAssembly wallet
let createdTx = await walletRpc.createTx({
  accountIndex: 0,
  address: await walletFull.getAddress(1, 0),
  amount: 250000000000n, // send 0.25 XMR (denominated in atomic units)
  relay: false // create transaction and relay to the network if true
});
let fee = createdTx.getFee(); // "Are you sure you want to send... ?"
await walletRpc.relayTx(createdTx); // relay the transaction

// recipient receives unconfirmed funds within 5 seconds
await new Promise(function(resolve) { setTimeout(resolve, 5000); });
assert(fundsReceived);

// save and close WebAssembly wallet
await walletFull.close(true);

1. cd your_project or mkdir your_project && cd your_project && npm init
2. npm install monero-ts
3. Add import moneroTs from "monero-ts" in your application code (or import types individually).

Node 20 LTS is recommended. Alternatively, Node 16 and 18 LTS work using the --experimental-wasm-threads flag.

1. Bundle your application code for a browser. See xmr-sample-webpack for an example project using Webpack.
2. Copy assets from ./dist to your web app's build directory.

1. Download and install Monero CLI.
2. Start monerod, e.g.: ./monerod --stagenet (or use a remote daemon).
3. Start monero-wallet-rpc, e.g.: ./monero-wallet-rpc --daemon-address http://localhost:38081 --stagenet --rpc-bind-port 38084 --rpc-login rpc_user:abc123 --wallet-dir ./

This project uses WebAssembly to package and execute Monero's source code for a browser or other WebAssembly-supported environment.

Compiled WebAssembly binaries are committed to ./dist for convenience, but these files can be built independently from source code:

1. Install and activate emscripten.
   1. Clone emscripten repository: git clone https://github.com/emscripten-core/emsdk.git
   2. cd emsdk
   3. git pull && ./emsdk install 3.1.66 && ./emsdk activate 3.1.66 && source ./emsdk_env.sh
   4. export EMSCRIPTEN=path/to/emsdk/upstream/emscripten (change for your system)
2. Clone monero-ts repository: git clone --recursive https://github.com/MoreloNetwork/monero-ts.git
3. cd monero-ts
4. ./bin/update_submodules.sh
5. Modify ./external/monero-cpp/external/monero-project/src/crypto/wallet/CMakeLists.txt from set(MONERO_WALLET_CRYPTO_LIBRARY "auto" ... to set(MONERO_WALLET_CRYPTO_LIBRARY "cn" ....
6. Build the monero-cpp submodule (located at ./external/monero-cpp) by following instructions for your system. This will ensure all dependencies are installed. Be sure to install unbound 1.19.0 to your home directory (~/unbound-1.19.0).
7. ./bin/build_all.sh (install monero-project dependencies as needed for your system)

1. Clone the project repository: git clone https://github.com/MoreloNetowkr/monero-ts.git
2. cd monero-ts
3. Start RPC servers:
   1. Download and install Monero CLI.
   2. Start monerod, e.g.: ./monerod --testnet (or use a remote daemon).
   3. Start monero-wallet-rpc, e.g.: ./monero-wallet-rpc --daemon-address http://localhost:38081 --testnet --rpc-bind-port 28084 --rpc-login rpc_user:abc123 --wallet-dir ./
4. Configure the appropriate RPC endpoints, authentication, and other settings in TestUtils.ts (e.g. WALLET_RPC_CONFIG and DAEMON_RPC_CONFIG).

• Run all tests: npm test
• Run tests by their description, e.g.: npm run test -- --grep "Can get transactions"

1. Start monero-wallet-rpc servers used by tests: ./bin/start_wallet_rpc_test_servers.sh
2. In another terminal, build browser tests: ./bin/build_browser_tests.sh
3. Access http://localhost:8080/tests.html in a browser to run all tests
