Send Funds

Overview

Once you have a wallet and some funds (tutorial), another common task is sending Dash to an address. (Sending Dash to a contact or a DPNS identity requires the Dashpay app, which has not been registered yet.)

Wallet Operations

The JavaScript SDK does not cache wallet information. It re-syncs the entire Core chain for some wallet operations (e.g. client.getWalletAccount()) which can result in wait times of 5+ minutes.

A future release will add caching so that access is much faster after the initial sync. For now, the skipSynchronizationBeforeHeight option can be used to sync the wallet starting at a certain block height.

const Dash = require('dash');

const clientOpts = {
  network: 'testnet',
  wallet: {
    mnemonic: 'your wallet mnemonic goes here',
    unsafeOptions: {
      skipSynchronizationBeforeHeight: 650000, // only sync from early-2022
    },
  },
};
const client = new Dash.Client(clientOpts);

const sendFunds = async () => {
  const account = await client.getWalletAccount();

  const transaction = account.createTransaction({
    recipient: 'yP8A3cbdxRtLRduy5mXDsBnJtMzHWs6ZXr', // Testnet2 faucet
    satoshis: 100000000, // 1 Dash
  });
  return account.broadcastTransaction(transaction);
};

sendFunds()
  .then((d) => console.log('Transaction broadcast!\nTransaction ID:', d))
  .catch((e) => console.error('Something went wrong:\n', e))
  .finally(() => client.disconnect());

// Handle wallet async errors
client.on('error', (error, context) => {
  console.error(`Client error: ${error.name}`);
  console.error(context);
});

What's Happening

After initializing the Client, we build a new transaction with account.createTransaction. It requires a recipient and an amount in satoshis (often called "duffs" in Dash). 100 million satoshis equals one Dash. We pass the transaction to account.broadcastTransaction and wait for it to return. Then we output the result, which is a transaction ID. After that we disconnect from the Client so node can exit.
