2. Send Move coin

This tutorial covers multiple ways to send coins on the Initia blockchain, and how to send transactions on Initia and Minitias.

Step 1: Get coin from faucet (Optional)

Get Testnet INIT tokens from the Initia Faucet if the account does not hold any tokens. See Get INIT token.

Step 2: Send Coin

CLI

Check balances before sending coin.

> initiad query bank balances [addr] \
    --node [rpc-url]:[rpc-port]

balances:
- amount: "100000000"
  denom: uinit
pagination:
  next_key: null
  total: "0"
  
> initiad query bank balances [addr] \
    --node [rpc-url]:[rpc-port]

balances: []
pagination: null

TIP: On Cosmos ecosystem, the u prefix on the token denom defines as μ(0.000001). The above example with 100,000,000 uinit means 100 INIT.

Send coin

    --gas auto --gas-adjustment 1.5 --gas-prices 0.15uinit \

Check balances after sending coin.

> initiad query bank balances [addr] \
    --node [rpc-url]:[rpc-port]

balances:
- amount: "99763570"
  denom: uinit
pagination:
  next_key: null
  total: "0"
> initiad query bank balances init1ehg0xxyksp69kfsvq8k336e7mpscf29nt50sjl \
    --node https://next-stone-rpc.initia.tech:443

balances:
- amount: "100000"
  denom: uinit
pagination:
  next_key: null
  total: "0"

You can check that the Sender's balance has decreased by fee + send amount, and the receiver's balance increased by the send amount.

initia.js

Check balances before sending coin.

import { LCDClient, MnemonicKey } from '@initia/initia.js';

async function checkBalances() {
  const lcd = new LCDClient('[rest-url]', {
    gasPrices: '0.15uinit',
    gasAdjustment: '1.5',
  });

  const key = new MnemonicKey({
    mnemonic:
      'beauty sniff protect ...',
  });
  const receiver = 'init10v3kg8hfvsj6tklfj5aam9ya5lmvtl9snqsawg';

  const senderBalances = await lcd.bank.balance(key.accAddress);
  const receiverBalances = await lcd.bank.balance(receiver);

  console.log('sender balances:', senderBalances[0]);
  // sender balances: Coins {
  //   _coins: {
  //     uinit: Coin { denom: 'uinit', amount: '100000000', isDecimal: false }
  //   }
  // }
  console.log('receiver balances:', receiverBalances[0]);
  // receiver balances: Coins { _coins: {} }
}

checkBalances();

TIP: On Cosmos ecosystem, the u prefix on the token denom defines as μ(0.000001). The above example with 100,000,000 uinit means 100 INIT.

Send coin

import { LCDClient, MnemonicKey, MsgSend, Wallet } from '@initia/initia.js';

async function sendCoin() {
  const lcd = new LCDClient('[rest-url]', {
    gasPrices: '0.15uinit',
    gasAdjustment: '1.5',
  });

  const key = new MnemonicKey({
    mnemonic:
      'beauty sniff protect ...',
  });
  const wallet = new Wallet(lcd, key);
  const receiver = 'init10v3kg8hfvsj6tklfj5aam9ya5lmvtl9snqsawg';

  const msgs = [
    new MsgSend(
      key.accAddress, // sender
      receiver,       // receiver
      '100000uinit'   // amount
    ),
  ];

  // sign tx
  const signedTx = await wallet.createAndSignTx({ msgs });
  // send(broadcast) tx
  lcd.tx.broadcastSync(signedTx).then(res => console.log(res));
  // {
  //   height: 0,
  //   txhash: 'EA9021C165FF676820C4FB3C01DD88626FCE0202B1511F0DD42FB6A58C92C730',
  //   raw_log: '[]'
  // }
}

sendCoin();

  const senderBalances = await lcd.bank.balance(key.accAddress);
  const receiverBalances = await lcd.bank.balance(receiver);

  console.log('sender balances:', senderBalances[0]);
  // sender balances: Coins {
